Outcomes of laminectomy for neurogenic claudication based upon NCOS

Due to referring of patients with neurological claudication and the importance of treatment results in these patients، limited information about its results، and importance of this information، and to determine the results of laminectomy in patients with neurological claudication according to Neurogenic Claudication Outcome Score (NCOS)، this study was conducted in patients of several hospitals during 2009-2011.

This study was performed using Case Series method. All patients with neurological claudication diagnosis who had laminectomy surgery، were studied. Patients had been treated for at least three، were recalled and the results of treatment were evaluated based on NCOS scoring and 20 rating increase in the scale after the operation was considered as successful laminectomy and role of factors associated with success or failure was determined by regression analysis. Patients’ satisfaction was also evaluated.

study on 84 eligible patients was performed during two years. Patients’ aged 61±11 (30 to 84 years) and patients were followed for least one year. Average changes of NCOS score، before and after surgery was 42/71±18/75. A significant difference was found between before and after surgery NCOS. (p<0. 0001). Regression analysis showed that higher rank of NCOS before surgery، age، and gender affects the prognosis of treatment (p<0. 0001). 90. 47% of patients were satisfied with the surgery.

Laminectomy for patients with neurological claudication is useful and effective and recommended. It appears that NCOS parameters before surgery، age، and gender affect prognosis of laminectomy result. Therefore، more Analytical Research in this area is recommended.
