Abstract
We are presenting a prospective analysis and assessment for the results of the Coflex@ inter-spinous dynamic stabilization device with a 2 year follow up. The purpose of this study is to assess the efficacy and safety of the Coflex@ Posterior Dynamic Stabilization Implant.
A prospective analysis was performed on 121 patients (176 devices) treated with the Coflex@ Interspinous Implant. Indication for the treatment was spinal canal foraminal stenosis with nerve root irritation.
Pre- and postoperative disability and pain scores were measured using Oswestry disability score, functional assessment a radiological evaluation at pre-operative - three - six twelve and twenty-four month interval.
Data analysis revealed a high rate of patient satisfaction 92% of patients are satisfied and will have the surgery again 81% of patients had major improvement of their leg symptoms. 72% of patients reported improvement of their back pain symptoms this was more noted in the decompression group.
Two revision surgeries were carried out. One due to implant back-out and the second due to infection.
The Coflex@inter-spinous implant is a simple surgical treatment strategy with a low risk. Early results show a good improvement of both clinical and radiological parameters combined with patient satisfaction with better outcome achieved if combined with spinal decompression.
