1 Dynamic Interspinous Assisted Motion (DIAM) Compliance with NICE A.Kasis, K. Lingulta G. Reddy, T. Friesem Spinal Unit, North Tees Hospital

2 Non-rigid stablization? Non rigid stabilization of the L spine Alternative to fusion Distraction Some motion

3 First review, July 2005

4 DIAM Conforms to interspinous anatomy Minimal distrubance to segmental muscles Two independent laces

5 Devices reviewed by NICE Bronsard and Graf ligaments Dynesys systems (Pedicle screws) Mims device DIAM Wallis X stop.

8 Recommendations 1.Inform clinical governance 2.Patients, written information 3.Audit and review

9 Spinal unit, North Tees 10 patients (13 prosthesis) Average age 59 (38-78) 6 female

10 Indications 6 spinal stenosis 3 spinal stenosis with facet arthropathy 1 patient with 2 levels disc degenerations, not suitable fusion/disc replacement (Jehovah Witness)

11 Pre-op investigations MRI Plain X rays 2 patients had discography

12 9 spinal rehab with no benefit 4 sacral epidural injection One nerve root block Pre-op treatment

13 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)

14 Advantages No blood transfusion required No neurological complications No infection No spinal canal intrusion

15 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

16 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)

17 Recommendations Re-audit at a longer follow up Another literature review

18 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.
