ABSTRACT
STUDY DESIGN:
Prospective cohort study.PURPOSE:
Evaluation of the clinico-radiological outcome and complications of limited laminectomy and restorative spinoplasty in spinal canal stenosis. OVERVIEW OF LITERATURE It is critical to achieve adequate spinal decompression, while maintaining spinal stability.METHODS:
Forty-four patients with degenerative lumbar canal stenosis underwent limited laminectomy and restorative spinoplasty at our centre from July 2008 to December 2010. Four patients were lost to follow-up leaving a total of 40 patients at an average final follow-up of 32 months (range, 24-41 months). There were 26 females and 14 males. The mean+/-standard deviation (SD) of the age was 64.7+/-7.6 years (range, 55-88 years). The final outcome was assessed using the Japanese Orthopaedic Association (JOA) score.RESULTS:
At the time of the final follow-up, all patients recorded marked improvement in their symptoms, with only 2 patients complaining of occasional mild back pain and 1 patient complaining of occasional mild leg pain. The mean+/-SD for the preoperative claudication distance was 95.2+/-62.5 m, which improved to 582+/-147.7 m after the operation, and the preoperative anterio-posterior canal diameter as measured on the computed tomography scan was 8.3+/-2.1 mm, which improved to 13.2+/-1.8 mm postoperatively. The JOA score improved from a mean+/-SD of 13.3+/-4.1 to 22.9+/-4.1 at the time of the final follow-up. As for complications, dural tears occurred in 2 patients, for which repair was performed with no additional treatment needed.CONCLUSIONS:
Limited laminectomy and restorative spinoplasty is an efficient surgical procedure which relieves neurogenic claudication by achieving sufficient decompression of the cord with maintenance of spinal stability.
