| 【Abstract】 Objectives: To investigate the clinical outcomes of subtotal corpectomy combined with discectomy for multilevel cervical spondylosis. Methods: A total of 32 consecutive patients with multilevel cervical spondylosis undergoing subtotal corpecomy combined with discectomy from March 2002 to January 2012 wasretrospectively reviewed. This case series included 20 males and 12 females with an average age at surgery of 52.32±5.73 years(range, 48 to 76 years). Cervical spondylotic myelopathy was determined in 26 cases and mixed cervical spondylopathy in 6 cases . Three levels were involved in 29 cases, while four levels were involved in 3 cases. The mean preoperative JOA score was 8.07±1.82(5-11); the anterior column height was 67.29±2.63(61.98-73.01)mm; and C value of cervical curvature was 2.86±2.63[(-3.14)-8.42]. Anterior hybrid decompression and fusion was performed in all patients. In addition, the anterior column height and C value of cervical curvature were assessed radiographically at routine postoperative intervals of 1 week and 6, 12 months respectively. Results: The operation time was 105min in average(from 90 to 160min), and the amount of bleeding was 200ml in average(from 100 to 350ml). 1 case with postoperative choke cough and 2 cases with hoarseness improved gradually after correspondent treatment. All cases were regularly followed up for 12-24 months, with an average of 14.0±3.1 months. Solid fusion in all cases was noted 6-12 months later. No instrument failure was noted. The anterior column height, C value of cervical curvature and JOA scores significantly increased at 1 week, 6 and 12 months after operation(P<0.05). The improvement rate of neurological function was (68.38±11.07）% at 12 months after operation, with 11 excellent, 17 good and 4 fair. Conclusions: Subtotal vertebrectomy combined with anterior decompression through cervical disc space and fusion is safe and effective for multilevel cervical spondylosis. |
