01-08 differential diagnosis - expanded systemic causes
TRANSCRIPT
1 – DDx Back Pain Cervical Spine Thoracic Spine Lumbar Spine
NMS Bone Persistent, excruciating , often worse at night; ONSET: #=immediate
O/A: -Spondylosis→ altered alignment of facets→↑risk of strain or
lock
- may lead to hypermobility (esp initially), more often hypomobility
-Cervical bar Lhermitte’s sign (flexn –extn → ‘electric’ shock);
ΔΔ MS
- NRI ← osteophytosis (mechanical irritation)
Osteoporosis - #? – greatly ↑ risk of #, most commonly in
hip, wrist, spine. Contra to forceful TTT. Ca & Mg, Vit C & Vit D supplements, wt. bearing Exx, esp outside (vit D aids Ca absorption). Oestrogen also aids Ca absorb, prevents urinary excretion; progesterone MAY encourage new bone growth (tofu, sesame seeds etc have high progesterone content). Fosamax (alendronic acid) may be Pxx. Alendronic acid inhibits osteoclastic bone resorption. Controversial: may be a link ĉ osteonecrosis of jaw. Also systemic bioavailability after oral ingestion extremely low (~0.6%), affected by ingestion of food/fluids before or after (have to fast). Has also been argued that osteoclastic activity is natural/necessary, and alendronic acid may prevent breakdown of old bone (→ ↑ bone density) but the bone thus preserved is not necessarily stronger.
Spinal stenosis - see Neuro/Referred below
Cervical Rib (rare) ∞ TOS? Often incomplete, may be fibrous
→ will not show on x-ray (need MRI)
C2 # Klippel Feil Syndrome Dens #? Whiplash/rugby
Rib # - exquisitely ful, AGG deep breathing, tuning fork,
percussion, A-P & latl rib compression. NOTE: may not show on xray immed after injury Osteochondritis/Scheurmann’s (35% of pop,
although only 5% ∑atic); low TSp and T/L region, also affects LSp Kyphotic (/kypholordotic) posture – stretching
& weakening of TES, may cause hypoxic ; ↑ stress on C/T and ↑CSp lordosis →facet irritation, ↑wear and tear A/S – bamboo spine, a.m. stiffness(>30 mins), improve ĉ
exercise; on sacral springing, ankylosis evident on S/B; cervical hyperextn, thoracic kyphosis, ↓ LSp lordosis, hip & knee flexn contractures. Night , ↓ rib expansion. Slow onset (starts <40 yoa)
Scoliosis – This is a can of worms... MYTH: if a scoliosis
disappears when Pt sits, it is functional (that is a compensatory/acquired scoliosis, i.e. compensation for short LEx). Scolioses may be DEXTROscoliosis (CONVEXITY R) or LEVOscoliosis (CONVEXITY L); Functional vs. structural (following Ward et al 2002:619): Assess degree of functionality of scoliosis by standing postr to pt.” Pt bends forward until maximal rib hump on horizon. Pt then swings upper body right, then left, while clinician observes functional ability of rib hump to reduce. Amt of rib hump remaining indicates assoc structural scoliotic component. Functional scoliotic curves reduce ĉ S/B, rotn or forward bending”

Difficulty getting OOB. “Hitching Sx” – 2 step process moving from flexn to extn: 1st extend LSp into lordosis, then extending hip. May be Sx & ∑ of spinal stenosis: neurogenic claud, NRI, poss cauda equina. QL works against psoas →may affect ilio-hyp, ilio-ing & gen-fem Nn→groin (mimcs hip/SI referral)
Osteochondritis Spinal Stenosis – may be ass ĉ LBP, and/or paraesthesiae
unilatl/bilatl LExx, loss of B/B control. Neurogenic claudication: classically relieved by bending forward for a few seconds (leaning against wall etc). Dull ache across L/S when standing/walking. LMNL Sx at level, UMNL Sx below level of lesion (ataxia, hyperreflexia, proprioceptive deficits). SLRT & femoral n stretch will be –ive. ↓ LSp lordosis. °Δ pulses.
Osteoporotic Crush # - characteristic gibbus or acute
angle, formed when vert body collapses (‘Dowager’s hump’); loss of height (2-4cm / #). Ac regional back (usually low thoracic/high lumbar) rad → antr along costal margins. RISK FACTORS: post-menopausal (↓oestr & progest), low body fat, low Ca &/or Mg intake, high caffeine intake, bed rest, alcoholism, steroid use, (HIV) CD4 <200, liver disease

R/A (early CSp involve common) – contra to HVLAT, controversial
as to whether should TTT affected jts at all
Rib lesion (insp/exp): Costotransverse/vertebral - on palpation, often
worse at angle; on DEEP inspiration/coughing, tend to have ass. stretched ligs, therefore may recur
- Costochondral (antr) : Tietze’s – 50% at 2nd rib;
tender ful perichondral swelling over single(?) costal cart, often 2° to postr lesion
Facet irritation – less common than CSp or LSp, if

Myasthenia Gravis - see Systemic Causes
Postural fatigue: (MM hypoxia) -Hypomobility ∞ shortening – ch contracture of MM →
relative hypoxia of tissues (poor blood supply) → buildup of metabolites and inflammatory mediators (prostaglandins, Subs P, cytokines etc); move will relieve as pumps and flushes tissues – DO NOT TALK ABOUT ISCHAEMIA UNLESS THERE IS E.G. TOTAL OCCLUSION OF BLOOD SUPPLY (NECROSIS WILL SWIFTLY FOLLOW) – NOT A CH CONDITION!
Exaggerated kyphosis → TES
Breathing issues: - Intercostals - Diaphragm (esp around T/L)
Myasthenia Gravis - see Systemic Causes
Postural fatigue: -LES hypertonia ∞ hip extensor hypertonia -Link ĉ exaggerated A-P curves

Olecranon # or hyperextension injury – ass ĉ antr
capsular strain; for # assess on active extn vs. resisted extn: resisted extn will localise & intensify
Olecranon impingement – forced extn → ; often some
degree of valgus instability (↑medl gapping); caused by repetitive extn ĉ valgus component (e.g. overhead throwing/tennis strokes)
Avulsion/stress # [medl] epicondyle Radiocapitellar chondromalacia ← repetitive valgus
stress (throwing athletes, racquet sports) → compresses radial head into capitellum. May result in periosteal bruising, osteochondral injury or even loose body formation. PPW latl elbow ĉ swelling & locking; passive pronation-supination applied with an axial load → & crepitus, TTP latlly over radiocapitellar jt.
Osteochondritis dessicans – affects convex jt surface –

NOTE: Carpal bone probs tend to have well-localised (helps ΔΔ against e.g. tendonitis)
Scaphoid # - classic: fall onto outstretched hand.Local .
Hamate # - 2% of carpal #s. Those involving hook are more
common (30% ← repetitive swinging by golfers/bats racquets → stress #). Direct #s lso ass ĉ fall onto outstretched hand.

PPW non-specific shoulder ĉ overhead/cross-body activities, deep, vague in nature, often ass ĉ popping/clicking/catching, possible weakness and/or stiffness. Pt supine, flex UEx to 120° ĉ max ER, elbow flexed to 90°. +ve = on A-R elbow flexn. Kim et al (2003) state sensitivity of 89.7% & specificity 96.9% in detecting SLAP lesions

R/A – uncommon in elbow Radial/ulnar dislocation – radial sublux: children <4yoa; in
adults = housemaid’s elbow, due to axial Txx of extended, pronated forearm. May involve torn annular lig.
O/A – mainly DIPJs (swelling, ), Heberden’s nodes (DIP),
sometimes Bouchard’s nodes (PIP)
R/A (swan-neck deformity) – esp PIPJs, swollen; MM wasting
Triangular Fibrocartilage Complex dysfunction –
TFCC describes the ligamentous & cartilaginous structures that suspend the distal radius & ulnar carpus from distal ulna (improves functional wrist stability, cushions forces translated through ulnocarpal axis, and allows 6° of freedom of move). Differentiates humans from lower primates (Palmer 1981). PPW ulnar sided wrist , freq ĉ clicking. Caused: falls onto pronated extended wrist, power drill injuries (drill locks and rotates wrist instead of drill bit), disTxx force applied to volar forearm/wrist, distal radius #s.

Painful arc – following Neer (1972) impingement of rotator cuff
tendons (commonly supraspinatus) under coracoacromial arch. Stage 1: <25yoa, charac by ac inflamm, oedema, microhaemorrhage in rotator cuff. Stage 2: 25-40 yoa, sequel of St 1, charac by tendonitis & fibrosis. Stage 3: >40 yoa, mech disruption of tendon, Δs in coracoacromial arch e.g. osteophytosis along antr acromion. 2° impingement: occurs 2° to functional ↓ in supraspinatus outlet space ← underlying instability of G/H. HAWKIN’S TEST: Elevate Pts UEx to 90° while forcibly IR shoulder. = subacromial impinge/rotator cuff tendonitis. Bak & Fauno (1997) found Hawkin’s more sensitive for impingement than Neer’s test (IR upper humerus & forcibly flex → 180°).

TTT ĉ corticosteroids (most common reason for L/T use) – risk factor for osteoporosis – ask about menopause, nulliparity, Exx, FHx etc.
Heart (e.g. MI) → L - ask about: sweating, nausea, chest
discomfort, mouth/jaw/tooth when getting shoulder . Does shoulder increase with exertion that should not involve shoulder (climbing stairs, exercise bicycle)?
Liver → L - e.g. hepatitis, cirrhosis, metastatic Ca
Gallbladder, pancreatitis, perforated duodenal ulcer → R - ask about relnship with meals: eating REL
duodenal/pyloric ulcer; AGG gastric ulcer, gallbladder inflamm; 1-3 hrs after eating/between meals = duodenal/pyloric ulcer, gallstones; ask about effect of antacids (ulcers in general), NSAIDs Note: any structure contacting diaphragm may refer via PHRENIC N.

arcade of Struthers; 2 heads of FCU & FDP. Tinel’s between olecranon & medl epicondyle Tumour – e.g. metastasis to bone (night and other
constitutional Σs) Osteomyelitis – infection spreads (a) from bloodstream (b)
contiguously from adjacent infected area or (c) penetrating trauma/iatrogenically. Tibia, humerus, vertebrae, maxilla & mandibular bodies most prone to bloodborne infection due to anatomy of blood supply.
NRI – C6 (latl, thumb)/C7 (middle)/C8 (medl)
Carpal Tunnel Syndrome (Median n.) – more likely if
‘double crush’ e.g. combined ĉ pronator teres syndrome. Phalen’s test: must hold for at least one min. TInel’s: have to hit quite briskly (patella hammer is best)
Radial Tunnel Syndrome – postr interosseus n. night

Cubitus valgus/varus – Tardy ulnar n. palsy ass. ĉ excess
valgus
Loose body – ass. ĉ O/A, radiocapitellar chondromalacia Wrist/Shoulder dysfunction (compensatory mechanism)
(cf. shoulder): e.g. poor shoulder posture (protracted, tightened antr structures) → humerus held in IR → shortening of supinators (inc biceps brachii) → at EoR extn supinators taut → imbalance of elbow/wrist flexors/extensors → PDF epicondylitis.
Ganglion - common cause of ulnar n. compression in canal of

Bone # of femoral head – can be surprisingly aΣatic.
Pelvic # Osteoporosis – greatly ↑ risk of #, most commonly in hip,
wrist, spine. Contra to forceful TTT. Ca & Mg, Vit C & Vit D supplements, wt. bearing Exx, esp outside (vit D aids Ca absorption). Oestrogen also aids Ca absorb, prevents urinary excretion; progesterone MAY encourage new bone growth (tofu, sesame seeds etc have high progesterone content). Fosamax (alendronic acid) may be Pxx. Alendronic acid inhibits osteoclastic bone resorption. Controversial: may be a link ĉ osteonecrosis of jaw. Also systemic bioavailability after oral ingestion extremely low (~0.6%), affected by ingestion of food/fluids before or after (have to fast). Has also been argued that osteoclastic activity is natural/necessary, and alendronic acid may prevent breakdown of old bone (→ ↑ bone density) but the bone thus preserved is not necessarily stronger.

TTT ITB (tight?), VMO (weak?), hams (hypertonic?), adductors (hypo?), hip MM imbalances, foot pronation? (→tibial IR). Advice: relative rest, non-impact activities (swimming?), coldpacking esp post-activity, tell Pt could take up to 6/52 to resolve. If no resolution → imaging, possible surgery
Tibiofemoral disloc – traumatic onset, will nearly
always be ligamentous damage (strain/rupture), severe swelling
Loose bodies (→ locking) R/A

PID Reiter’s (arthritis, urethritis, uveitis) - See p7, SNAs A/S – See p7, SNAs AAA - NOTE: AA’s are often a∑atic as nociceptors do not
respond well to slow Δs. Palpate latl to rectus sheath for ‘pulsatile’ AA pulse. LBP may be only Σ on presenting. Ask about throbbing or burning . Check for radiofemoral delay.
Kidney stones
Charcot’s joints – sensorimotor loss, esp the loss of
proprioception, ass ĉ diabetic neuropathy → severe degenerative arthritis. Common in ankle & knee, also in shoulder (∞ ĉ periarthritis and adhesive capsulitis, 5x more common in diabetic population)
L3/4 referral – facet strain/apophysitis/lock; disc annular
strain/herniation/bulge

4th MTPJs (where latl plantar n. combines ĉ part of medl planter n. PDF pes planus, high heels/tight toe boxes (e.g. female footwear). Entrapment neuropathy. Neuralgic on pressure. May also be P+Ns/numbness.
Foot drop (∞ cauda equina ) – Pt cannot heel-walk. May notice on
greeting Pt (while walking, high step). May be caused by L5 NRC (e.g. herniation), sciatic n. compression (direct trauma, iatrogenic), peroneal/fibular n. palsy (esp at fibular head), lumbosacral plexus (cauda equina), spinal cord compression (poliomyelitis, SOL, cervical bar), stroke/TIA/brain tumour, MS
Intermittent claudication – Neurogenic: ↓ blood flow to Nn in
spinal foraminae, spinal stenosis. Probably some at rest (i.e. is not relieved as swiftly as vascular claud, may persist for hours). Walk further when flexed (shopping trolley, uphill, mowing grass), Pulses NAD, ° LExx skin Δs. May be ° neuro
Sx or ∑s. Vascular: stops immediately when Pt stops walking/sits. May be
abŇ pulses (HOWEVER may not be apparent at rest), sin cold, dry flaky (poor perfusion)

7 – Osteoarthritis vs. Rheumatoid Arthritis
Osteoarthritis Rheumatoid Arthritis Definition Non-inflammatory disorder of synovial joints, charac. by articular surface wear &
formation of new bone
Auto-immune inflammatory multi-systemic connective tissue disorder
Epidemiology 80% m. & 89% f. over the age of 75yrs, ♀ > ♂ 3:1
1-2 % general population. , ♀ > ♂ 3:1. Onset any time 10-70 yoa, but peak: 30-40 yoa.
Aetiology Primary O/A = idiopathic (many factors, but cause unknown) Secondary O/A = consequent to trauma, congenital abnormalities, infection, functional problems, avascular necrosis, neuropathy, metabolic/endocrine diseases, crystal arthropathies, or iatrogenesis.
Unknown – sex hormones may be involved (often 1st
appears after pregnancy, or remits during, contraceptive pill appears to have mild protective influence), also genetic/immunological component likely
Pathophysiology Stage 1: Breakdown of articular surface Stage 2: Synovial irritation Stage 3: Chondral remodelling Stage 4: Eburnation of bone & cyst formation Stage 5: Disorganization
Ch inflammatory synovitis: proliferation of villi that contain infiltrates of lymphocytes,
macrophages & plasma cells. Synoviocytes secrete cytokines → stimulate further synoviocyte prod, cartilage resorption, further cytokine production (may →progressive nature of disease). In established disease these mild inflammatory lesions develop into RHEUMATOID NODULES (pathognomic of R/A) in many tissues – heart/pericardium, lungs, blood Vv, skin/subcut tissue, eye, salivary/lacrimal glands etc. Synovium devs tumour-like mass – PANNUS that extends from synovial margin eroding articular cartilage & invading bone. Exudate within jt → swollen S/Ts
Clinical Features Affects mainly: 1st
CMCJ, 1st
MTPJ, knee & hip (joints that have undergone most recent evolutionary Δ?) AGG wt. bearing/use; worse after activity/at end of day REL by rest Stiffness, weakness (usually 2° to disuse) Crepitus/clicking Swelling – may be bony, cold, hard. Often ĉ additional effusion (←synovitis?) Locking/unsteadiness ← loose bodies/irregular jt surface MM weakness/wasting ↓ RoM Jt deformities – e.g. fixed flex
n, Heberden’s/Bouchard’s nodes
NRI/impingement - 2° to Spondylosis
Commonly affected initially: PIPJs, MCPJs, MTPJs, wrist, CSp Knee common in later stages, along ĉ hip, ankle. Likely to be symmetrical BUT 20% Pts present initially as monartrhitis, usually knee or wrist Jt & stiffness, esp a.m. Low-grade pyrexia, malaise, fatigue, wt loss ass ĉ anorexia Sjögren’s Syndrome in up to 40% of Pts (dry, sore eyes, nose & mouth). Uveitis & scleritis important ocular manifestations RESP: nodules, interstitial fibrosis, obstruction small bronchi → wheeze, exertional dyspnoea CVS: pericarditis, vasculitis (esp fingers & nail beds), mitral valve disease, Raynaud’s, anaemia NERVOUS: cervical myelopathy (most common rheum cause of death in R/A), CTS
DDx
Depends on whether mono-, oligo- or polyarthritic on presentation... SLE, allergic/viral onset polyarthritis, psoriatic arthritis, 1° generalised O/A
Medical Management
NSAIDs, intra-articular steroid injections, glucosamine & chondroitin supplement (may ↓ Σs, unlikely to promote regrowth of cart), artificial synovial fluid (M/T, lasts appx 6/12); osteotomy, arthrodesis, debridement, jt. resurfacing, total joint replacement
NSAIDs, DMARDs (disease-modifying anti-rheumatic drugs, a group of otherwise unrelated compounds e.g. methotrexate, sulphasalazine, anti-malarials, gold) steroids
Osteopathic Management
Advice: explanation of condition and reassurance; keep active but modify causing activities: low-impact exercise (swimming, exercise bikes), wt. loss if viscerotopic, walking stick c-lat
l side if hip/knee affected etc. Disuse (not just overuse) can → Δ in
function and levels – if any given jt not used through full RoM → poorer health of that joint (and those surrounding it). Bony remodelling is an ongoing process → maintain function through manual therapy & Exx.
Exx to maintain RoM, MM bulk around affected joints, and general fitness. Avoid TTT of neck (synovitis around C1/2 may → excess move or vertical subluxation of C1 relative to C2; both may lead to progressive spastic quadraparesis or transient episodes of medullary dysfunction; also transverse ligament likely to be affected – CONTRA TO HVLAT), do not TTT during active phase/flare-up. Controversial: only treat unaffected joints?
SERONEGATIVE ARTHROPATHIES (SNAs)
Group of overlapping forms of INFLAMMATORY JOINT DISEASE COMMON FEATURES: Tendency to affect the SPINE RhF negative ↑ incidence of HLA-B27 FAMILY HISTORY of single/multiple SLAs PPW: Back pain AGG prolonged inactivity/sitting/lying REL activity
When Pts present ĉ back AGG prolonged sitting/lying down, REL activity, suspect SNA... Enthesopathy is responsible for many of the features: inflammation, fibrosis, ossification/reactive bone formation at the enthesis

Reiter’s/Reactive Arthritis Triad of Σs: Conjunctivitis Urethritis Arthritis
Peak incidence age 30 yoa, following enteric infection distr much wider – children & elderly may be affected
Follows intestinal/dysenteric or genital infection (major identifiable cause inflamm arthritis in young adults in West)
- PERIPHERAL ARTHRITIS: starts 2/52 after infect; asymmetrical, additive - UVEITIS/CONJUNCTIVITIS - URETHRITIS: dysuria/urethral discharge, polyuria, prostatitis, balanitis, cystitis
Treat infection (ABx); for arthritis: NSAIDs, rest. If spondylitis is present, TTT as per A/S (above). In a
c stages jt
aspiration and corticosteroid injections may be performed.
Psoriatic Arthritis
Psoriasis affects 1-2% [Caucasian] population. 5-10% of these will have PsA. m=f; 30% of cases have FHx Peak onset 36-46 yoa Most Pts ĉ PsA have pre-existing skin/nail psoriasis, but jt inflamm precedes psoriasis in c. 15% of cases.
Aetiology unknown; trauma, stress, infection all implicated. Hormonal factors also seem to be involved - PsA usually improves during pregnancy and there is often post-partum flare.
DIPJ DISEASE: m>f, sausage digits ARTHRITIS MUTILANS: <5%. Small jts hands & feet ĉ osteolysis of phalanges PERIPHERAL OLIGO/POLYARTHRITIS: most common subgroup; affects large/small jts. Sausage digits SPONDYLITIS: mainly SPINAL involve. >half Pts have CSp involve.
