Compliance with NICE
A. Kasis, K. Lingulta

Spinal Unit, North Tees Hospital
Non-rigid stablization?
• Non rigid stabilization of the L spine
• Alternative to fusion
• Distraction
• Some motion
First review, July 2005
DIAM
• Conforms to interspinous anatomy
• Minimal distrubance to segmental muscles
• Two independent laces
Devices reviewed by NICE
• Bronsard and Graf ligaments
• Dynesys systems (Pedicle screws)
• Mims device
• DIAM
• Wallis
• X stop.

Recommendations
1. Inform clinical governance
2. Patients, written information
3. Audit and review
Spinal unit, North Tees
• 10 patients (13 prosthesis)
• Average age 59 (38-78)
• 6 female
Indications
• 6 spinal stenosis
• 3 spinal stenosis with facet arthropathy
• 1 patient with 2 levels disc degenerations, not suitable fusion/disc replacement (Jehovah Witness)
Pre-op investigations
• MRI
• Plain X rays
• 2 patients had discography
9 spinal rehab with no benefit
4 sacral epidural injection
One nerve root block
Pre-op treatment
• Most common level L4/5
• Most common size used 10 and 12
• Average length of surgery about 40 minutes per prosthesis
• Length of stay 1.3 days per prosthesis (1-3)
Advantages
• No blood transfusion required
• No neurological complications
• No infection
• No spinal canal intrusion
Compliance with NICE
All patients received NICE leaflet
Notes record:• 9/10 record of giving the leaflet.• 10/10 record of all possible complications• 10/10 record of success rate, and possible
requirement of additional procedure• 10/10 record of new procedure
Satisfaction
• 10/10 patients were satisfied with the procedure, at the first review in the clinic.
• Average follow up is 2.3 months (1.5-6)
Recommendations
• Re-audit at a longer follow up
• Another literature review
57 y old lorry driver (Jehovah Witness), with 2 level degenerative disease, 3 months post DIAM procedure, patient returned to work 4 weeks post
op.
