Surgical results in anterior cervical discectomy and fusion using a countersunk interlocking autogenous iliac bone graft.

Abstract

The purpose of this study was to evaluate the surgical results of anterior cervical discectomy and fusion using a countersunk interlocking autogenous iliac bone graft. Two hundred thirty-two patients were followed for an average of 6.8 years. All patients suffered neck and arm pain. Two hundred twenty patients received conservative treatment for at least six months. Overall results were satisfactory in 202 patients (87%) and unsatisfactory in 30 patients (13%). The pseudoarthrosis rate was 6.5% which is significantly lower than previous reports. The premise of this technique is that the interlocking graft prevents migration, promotes fusion by providing immobilization, and restores the height of the interspace. Anterior cervical discectomy and fusion, using a countersunk interlocking autogenous iliac bone graft, is a satisfactory surgical procedure in which successful pain relief is to be expected.
