bull 469 studies 249 to be scientifically admissible bull 101 articles related to the burden and determinants of neck pain in the general
population bull Incidence ranged from 0055 per 1000 person years(disc herniation with
radiculopathy) to bull 213 per 1000 persons (self-reported neck pain) bull Incidence of neck injuries during competitive sports ranged from 002 to 21 per
1000 exposures bull The 12-month prevalence of pain typically ranged between 30 and 50 the 12-
month prevalence of activity-limiting pain was 17 to 115 bull Neck pain was more prevalent among women and prevalence peaked in middle
age bull Risk factors for neck pain included genetics poor psychological health and
exposure to tobacco Disc degeneration was not identified as a risk factor bull The use of sporting gear (helmets face shields) to prevent other types of injury
was not associated with increased neck injuries in bicycling hockey or skiing

bull RetrospectiveObjective To assess the incidence of complications associated with fluoroscopically guided percutaneous radiofrequency denervation of the lumbar facet joints
bull facet joint radiofrequency denervation procedures performed at the Mayo Clinic in Jacksonville during a 5-year period
bull Ninety-two patients received a total of 616 radiofrequency lesions during 116 separate denervation procedures An average of 5 plusmn 3 lesions were performed during each radiofrequency denervation procedure
bull Six minor complications were identified yielding a 10 overall incidence of minor complications per radiofrequency site
bull Complications included 3 cases of localized pain lasting more than 2 weeks (05) and 3 cases of neuritic pain lasting less than 2 weeks (05) No cases of infection new motor deficits or new sensory deficits were identified
bull Conclusions Fluoroscopically guided percutaneous radiofrequency denervation of the lumbar facets is associated with an overall 10 incidence of minor complications per lesion site
Cervical Degenerative Disc Disease (C-DDD)
Abstract Cervical MRI 497 ASYMPTOMATIC subjects

bull 20s 17 of discs of men 12 of those of women bull 60lt 86 and 89 of discs of both men and women
bull demonstrable compression of the spinal cord was observed in 76 of subjects mostly over 50 years of age
bull ldquoOur results should be taken into account when interpreting the MRI findings in patients with symptomatic disorders of the cervical spinerdquo

When Is C-DDD Clinically significant (C-DDD)
Results A systematic review of the literature demonstrated that cervical discography plays a significant role in selecting surgical candidates and improving outcomes despite concerns regarding the false-positive rate lack of standardization and assorted potential confounding factors Based on the studies utilizing the International Association for the Study of Pain (IASP) criteria the data show a prevalence rate ranging between 16 and 20 Based on the 3 studies that utilized IASP criteria during the performance of cervical discography the evidence derived from studies evaluating the diagnostic validity of the procedure the indicated level of evidence is Level II-2 based on modified US Preventive Services Task Force (USPSTF) criteria
bullBeyond the debate regarding its efficacy in identifying the site of cervical symptomatology and directing appropriate intervention are the potential morbidity and mortality associated with this diagnostic procedure bullDiscitis subdural empyema spinal cord injury vascular injury and prevertebral abscess have all been reported as complications of diagnostic cervical disc injection bullRetrospective 4400 cervical disc injections in 1357 patients performed by an experienced radiologist between 1988 and 1993 to define the morbidity and mortality associated with discography bullIn addition we reviewed the extant medical literature on the complications of this controversial procedure bull This study demonstrates significant complications from diagnostic discography procedures occurring in less than 06 of the patients and 016 of the cervical disc injections

bull Herniation
bull Axial neck pain is originated from sinuvertebral nerve located in ventral epidural spaces which has been described to be related to central or paramedian disc herniation
bull 108 patients who underwent IL and TF epidural injections axial neckinterscapular pain due to central or paramedian cervical disc herniation were included
bull Successful pain relief was defined if a 50 or more reduction of NRS score was achieved in comparison with pretreatment one
bull Overall 79 (731) and 57 (528) 2 and 8 weeks respectively Seventy-six (704) and 52 (481) had successful functional improvement at 2 and 8 weeks Cervical epidural injection showed favorable results in 2 weeks and moderate results in 8 weeks in patients with axial pain due to cervical disc herniation

Cervical Radiculopathy
C-Radic Non-operative Management
bull ldquoThe axons of these nerves are either compressed directly or are rendered ischemic by compression of their blood supply Symptoms of sensory or motor loss arise as a result of block of conduction along the affected axons The features of cervical radiculopathy therefore are essentially negative in nature they reflect loss of function In contrast pain is a positive feature not caused by loss of nerve function
bull For this reason cervical radicular pain cannot be summarily attributed to the same causes as those of radiculopathy Compression of axons does not elicit pain If compression is to be invoked as a mechanism for pain it must explicitly relate to compression of a dorsal root ganglionldquo

Cervical Radiculopathy
bull ldquoAs opposed to compression there are growing contentions that cervical radicular pain may be caused by inflammation of the cervical nerve roots This mechanism might be applicable to radicular pain caused by disc protrusions because inflammatory exudates have now been isolated from cervical disc material However inflammation cannot be invoked as the mechanism of radicular pain caused by noninflammatory lesions such as tumors cysts and osteophytes For these conditions compression of the dorsal root ganglion is the only mechanism for which there is experimental evidence
bull However none of these considerations bear on the causes and mechanisms of neck pain Whatever its cause and whatever its mechanism cervical radicular pain is perceived in the upper limb

ndash Epidural steroid injections
bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention
bull Complications of Cervical Epidural Nerve Blocks with Steroids A Prospective Study of 790 Consecutive Blocks WALDMAN STEVEN D MD MayJune 1989 - Volume 14 - Issue 3pp 99-159
790 consecutive cervical epidural nerve blocks were followed prospectively for a six-week period for early as well as delayed complications
bull Two patients sustained unintentional dural puncture Both patients ultimately required cervical epidural blood patch
bull Three patients experienced vasovagal syncope during CSENB They were easily resuscitated
bull One late complication of superficial infection at the injection site was noted The patient recovered without sequela
bull From the above data it appears that CSENB represents a safe modality in the treatment of a variety of painful conditions
bull Study Design A prospective concurrently controlled randomized multicenter trial of an anterior Bagby and Kuslich cervical fusion cage (BAKC Sulzer Spine-Tech Minneapolis MN) for treatment of degenerative disc disease of the cervical spineObjectives To report clinical results with maximum 24-month follow-up of fusions performed with the BAKC fusion cageSummary of Background Data Threaded lumbar cages have been used during the past decade as a safe and effective surgical solution for chronic disabling low back pain Threaded cages have now been developed for use in anterior cervical interbody fusions to obviate the need for allografts or autogenous bone grafting procedures while providing initial stability during the fusion processMethods Patients with symptomatic cervical discogenic radiculopathy were treated with either anterior cervical discectomy with uninstrumented bone-only fusion (ACDF) or BAKC fusion cage(s) Independent radiographic assessment of fusion was made and patient-based outcome was assessed by visual analog pain scale and a Short Form (SF)-36 Health Status QuestionnaireResults Data analysis included 344 patients at 1 year and 180 at 2 years When the two cage groups (hydroxya patite-coated or noncoated) were compared with the ACDF group similar outcomes were noted for duration of surgery hospital stay improvements in neck pain and radicular pain in the affected limb improvements in the SF-36 Physical Component subscale and Mental Component subscale and the patientsrsquo perception of overall surgical outcome Symptom improvements were maintained at 2 years A greater percentage of patients with ACDF needed an iliac crest bone harvest than did BAKC patients (67vsmdash 3)
bull Successful fusion for one-level procedures at 12 months was 979 for the BAKC groups and 897 for the ACDF group (P lt 005)
bull The complication rate for the ACDF group was 204 compared with an overall complication rate of 118 with BAKC

bull For this reason cervical radicular pain cannot be summarily attributed to the same causes as those of radiculopathy Compression of axons does not elicit pain If compression is to be invoked as a mechanism for pain it must explicitly relate to compression of a dorsal root ganglionldquo

Cervical Radiculopathy
bull ldquoAs opposed to compression there are growing contentions that cervical radicular pain may be caused by inflammation of the cervical nerve roots This mechanism might be applicable to radicular pain caused by disc protrusions because inflammatory exudates have now been isolated from cervical disc material However inflammation cannot be invoked as the mechanism of radicular pain caused by noninflammatory lesions such as tumors cysts and osteophytes For these conditions compression of the dorsal root ganglion is the only mechanism for which there is experimental evidence
bull However none of these considerations bear on the causes and mechanisms of neck pain Whatever its cause and whatever its mechanism cervical radicular pain is perceived in the upper limb

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention
bull Complications of Cervical Epidural Nerve Blocks with Steroids A Prospective Study of 790 Consecutive Blocks WALDMAN STEVEN D MD MayJune 1989 - Volume 14 - Issue 3pp 99-159
790 consecutive cervical epidural nerve blocks were followed prospectively for a six-week period for early as well as delayed complications
bull Two patients sustained unintentional dural puncture Both patients ultimately required cervical epidural blood patch
bull Three patients experienced vasovagal syncope during CSENB They were easily resuscitated
bull One late complication of superficial infection at the injection site was noted The patient recovered without sequela

When Is C-DDD Clinically significant (C-DDD)
Results A systematic review of the literature demonstrated that cervical discography plays a significant role in selecting surgical candidates and improving outcomes despite concerns regarding the false-positive rate lack of standardization and assorted potential confounding factors Based on the studies utilizing the International Association for the Study of Pain (IASP) criteria the data show a prevalence rate ranging between 16 and 20 Based on the 3 studies that utilized IASP criteria during the performance of cervical discography the evidence derived from studies evaluating the diagnostic validity of the procedure the indicated level of evidence is Level II-2 based on modified US Preventive Services Task Force (USPSTF) criteria
bullBeyond the debate regarding its efficacy in identifying the site of cervical symptomatology and directing appropriate intervention are the potential morbidity and mortality associated with this diagnostic procedure bullDiscitis subdural empyema spinal cord injury vascular injury and prevertebral abscess have all been reported as complications of diagnostic cervical disc injection bullRetrospective 4400 cervical disc injections in 1357 patients performed by an experienced radiologist between 1988 and 1993 to define the morbidity and mortality associated with discography bullIn addition we reviewed the extant medical literature on the complications of this controversial procedure bull This study demonstrates significant complications from diagnostic discography procedures occurring in less than 06 of the patients and 016 of the cervical disc injections

Results A systematic review of the literature demonstrated that cervical discography plays a significant role in selecting surgical candidates and improving outcomes despite concerns regarding the false-positive rate lack of standardization and assorted potential confounding factors Based on the studies utilizing the International Association for the Study of Pain (IASP) criteria the data show a prevalence rate ranging between 16 and 20 Based on the 3 studies that utilized IASP criteria during the performance of cervical discography the evidence derived from studies evaluating the diagnostic validity of the procedure the indicated level of evidence is Level II-2 based on modified US Preventive Services Task Force (USPSTF) criteria

bull ldquoThe axons of these nerves are either compressed directly or are rendered ischemic by compression of their blood supply Symptoms of sensory or motor loss arise as a result of block of conduction along the affected axons The features of cervical radiculopathy therefore are essentially negative in nature they reflect loss of function In contrast pain is a positive feature not caused by loss of nerve function
bull For this reason cervical radicular pain cannot be summarily attributed to the same causes as those of radiculopathy Compression of axons does not elicit pain If compression is to be invoked as a mechanism for pain it must explicitly relate to compression of a dorsal root ganglionldquo

bull ldquoAs opposed to compression there are growing contentions that cervical radicular pain may be caused by inflammation of the cervical nerve roots This mechanism might be applicable to radicular pain caused by disc protrusions because inflammatory exudates have now been isolated from cervical disc material However inflammation cannot be invoked as the mechanism of radicular pain caused by noninflammatory lesions such as tumors cysts and osteophytes For these conditions compression of the dorsal root ganglion is the only mechanism for which there is experimental evidence

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

bull ldquoThe axons of these nerves are either compressed directly or are rendered ischemic by compression of their blood supply Symptoms of sensory or motor loss arise as a result of block of conduction along the affected axons The features of cervical radiculopathy therefore are essentially negative in nature they reflect loss of function In contrast pain is a positive feature not caused by loss of nerve function
bull For this reason cervical radicular pain cannot be summarily attributed to the same causes as those of radiculopathy Compression of axons does not elicit pain If compression is to be invoked as a mechanism for pain it must explicitly relate to compression of a dorsal root ganglionldquo

bull ldquoAs opposed to compression there are growing contentions that cervical radicular pain may be caused by inflammation of the cervical nerve roots This mechanism might be applicable to radicular pain caused by disc protrusions because inflammatory exudates have now been isolated from cervical disc material However inflammation cannot be invoked as the mechanism of radicular pain caused by noninflammatory lesions such as tumors cysts and osteophytes For these conditions compression of the dorsal root ganglion is the only mechanism for which there is experimental evidence

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

790 consecutive cervical epidural nerve blocks were followed prospectively for a six-week period for early as well as delayed complications
bull Two patients sustained unintentional dural puncture Both patients ultimately required cervical epidural blood patch
bull Three patients experienced vasovagal syncope during CSENB They were easily resuscitated
bull One late complication of superficial infection at the injection site was noted The patient recovered without sequela
bull From the above data it appears that CSENB represents a safe modality in the treatment of a variety of painful conditions
bull Study Design A prospective concurrently controlled randomized multicenter trial of an anterior Bagby and Kuslich cervical fusion cage (BAKC Sulzer Spine-Tech Minneapolis MN) for treatment of degenerative disc disease of the cervical spineObjectives To report clinical results with maximum 24-month follow-up of fusions performed with the BAKC fusion cageSummary of Background Data Threaded lumbar cages have been used during the past decade as a safe and effective surgical solution for chronic disabling low back pain Threaded cages have now been developed for use in anterior cervical interbody fusions to obviate the need for allografts or autogenous bone grafting procedures while providing initial stability during the fusion processMethods Patients with symptomatic cervical discogenic radiculopathy were treated with either anterior cervical discectomy with uninstrumented bone-only fusion (ACDF) or BAKC fusion cage(s) Independent radiographic assessment of fusion was made and patient-based outcome was assessed by visual analog pain scale and a Short Form (SF)-36 Health Status QuestionnaireResults Data analysis included 344 patients at 1 year and 180 at 2 years When the two cage groups (hydroxya patite-coated or noncoated) were compared with the ACDF group similar outcomes were noted for duration of surgery hospital stay improvements in neck pain and radicular pain in the affected limb improvements in the SF-36 Physical Component subscale and Mental Component subscale and the patientsrsquo perception of overall surgical outcome Symptom improvements were maintained at 2 years A greater percentage of patients with ACDF needed an iliac crest bone harvest than did BAKC patients (67vsmdash 3)
bull Successful fusion for one-level procedures at 12 months was 979 for the BAKC groups and 897 for the ACDF group (P lt 005)

Results A systematic review of the literature demonstrated that cervical discography plays a significant role in selecting surgical candidates and improving outcomes despite concerns regarding the false-positive rate lack of standardization and assorted potential confounding factors Based on the studies utilizing the International Association for the Study of Pain (IASP) criteria the data show a prevalence rate ranging between 16 and 20 Based on the 3 studies that utilized IASP criteria during the performance of cervical discography the evidence derived from studies evaluating the diagnostic validity of the procedure the indicated level of evidence is Level II-2 based on modified US Preventive Services Task Force (USPSTF) criteria

bull ldquoThe axons of these nerves are either compressed directly or are rendered ischemic by compression of their blood supply Symptoms of sensory or motor loss arise as a result of block of conduction along the affected axons The features of cervical radiculopathy therefore are essentially negative in nature they reflect loss of function In contrast pain is a positive feature not caused by loss of nerve function
bull For this reason cervical radicular pain cannot be summarily attributed to the same causes as those of radiculopathy Compression of axons does not elicit pain If compression is to be invoked as a mechanism for pain it must explicitly relate to compression of a dorsal root ganglionldquo

Cervical Radiculopathy
bull ldquoAs opposed to compression there are growing contentions that cervical radicular pain may be caused by inflammation of the cervical nerve roots This mechanism might be applicable to radicular pain caused by disc protrusions because inflammatory exudates have now been isolated from cervical disc material However inflammation cannot be invoked as the mechanism of radicular pain caused by noninflammatory lesions such as tumors cysts and osteophytes For these conditions compression of the dorsal root ganglion is the only mechanism for which there is experimental evidence
bull However none of these considerations bear on the causes and mechanisms of neck pain Whatever its cause and whatever its mechanism cervical radicular pain is perceived in the upper limb

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention
bull Complications of Cervical Epidural Nerve Blocks with Steroids A Prospective Study of 790 Consecutive Blocks WALDMAN STEVEN D MD MayJune 1989 - Volume 14 - Issue 3pp 99-159
790 consecutive cervical epidural nerve blocks were followed prospectively for a six-week period for early as well as delayed complications
bull Two patients sustained unintentional dural puncture Both patients ultimately required cervical epidural blood patch
bull Three patients experienced vasovagal syncope during CSENB They were easily resuscitated
bull One late complication of superficial infection at the injection site was noted The patient recovered without sequela
bull From the above data it appears that CSENB represents a safe modality in the treatment of a variety of painful conditions
bull Study Design A prospective concurrently controlled randomized multicenter trial of an anterior Bagby and Kuslich cervical fusion cage (BAKC Sulzer Spine-Tech Minneapolis MN) for treatment of degenerative disc disease of the cervical spineObjectives To report clinical results with maximum 24-month follow-up of fusions performed with the BAKC fusion cageSummary of Background Data Threaded lumbar cages have been used during the past decade as a safe and effective surgical solution for chronic disabling low back pain Threaded cages have now been developed for use in anterior cervical interbody fusions to obviate the need for allografts or autogenous bone grafting procedures while providing initial stability during the fusion processMethods Patients with symptomatic cervical discogenic radiculopathy were treated with either anterior cervical discectomy with uninstrumented bone-only fusion (ACDF) or BAKC fusion cage(s) Independent radiographic assessment of fusion was made and patient-based outcome was assessed by visual analog pain scale and a Short Form (SF)-36 Health Status QuestionnaireResults Data analysis included 344 patients at 1 year and 180 at 2 years When the two cage groups (hydroxya patite-coated or noncoated) were compared with the ACDF group similar outcomes were noted for duration of surgery hospital stay improvements in neck pain and radicular pain in the affected limb improvements in the SF-36 Physical Component subscale and Mental Component subscale and the patientsrsquo perception of overall surgical outcome Symptom improvements were maintained at 2 years A greater percentage of patients with ACDF needed an iliac crest bone harvest than did BAKC patients (67vsmdash 3)
bull Successful fusion for one-level procedures at 12 months was 979 for the BAKC groups and 897 for the ACDF group (P lt 005)

bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

bull This prospective study with independent clinical review was set up to monitor the clinical outcome of patients when using serial periradicularepidural corticosteroid injection techniques in managing cervical radiculopathy
bull Over a 10 year period between 1986 and 1995 a consecutive series of 68 secondary referral patients presenting with cervical radiculopathy were entered into the study
bull Of the 64 patients (94) who under-went imaging relevant pathology thought to correlate with the clinical presentation was demonstrated in all but one patient
bull Serial periradicularepidural corticosteroid injections were used to control pain an average of 25 injections was administered per patient (range 1ndash6)
bull Patients underwent a final clinical examination when their pain had remained satisfactorily under control for an average of 7 months (range 1ndash23 months) They subsequently were reassessed by an independent clinician at an average of 39 months (range 4ndash112 months) after initial presentation via a telephone interview
bull Despite the fact that all 68 patients were potential surgical candidates they all made a satisfactory recovery without the need for surgical intervention
bull Forty-eight patients (76) did not experience any arm pain and of the 15 patients (24) who did this improved from 10 to an average of 2 (range 1ndash4) on a 10-point pain scale Thus patients with cervical radiculopathy make a satisfactory recovery with serial periradicularepidural corticosteroid injections without the need for surgical intervention

bull Two patients sustained unintentional dural puncture Both patients ultimately required cervical epidural blood patch
bull Three patients experienced vasovagal syncope during CSENB They were easily resuscitated

Cervical Radiculopathy
bull ldquoAs opposed to compression there are growing contentions that cervical radicular pain may be caused by inflammation of the cervical nerve roots This mechanism might be applicable to radicular pain caused by disc protrusions because inflammatory exudates have now been isolated from cervical disc material However inflammation cannot be invoked as the mechanism of radicular pain caused by noninflammatory lesions such as tumors cysts and osteophytes For these conditions compression of the dorsal root ganglion is the only mechanism for which there is experimental evidence
bull However none of these considerations bear on the causes and mechanisms of neck pain Whatever its cause and whatever its mechanism cervical radicular pain is perceived in the upper limb
