The purpose of this study was to evaluate the use of titanium mesh cage (filled with morselized local bone from a corpectomy) and locking plate after anterior corpectomy for multi-level disease of the cervical spine. With this procedure, since 1999, we treated 16 patients (6 men and 10 women with a mean age of 61.6 years) for cervical myelopathy caused by OPLL (8 cases), vertebral tumors (3 cases), spondylosis (3 cases), and osteomyelitis (2 cases). Corpectomy was performed in one (8 cases), two (7 cases), and three vertebrae (1 case). Autologous bone fragment were taken from the removed vertebra, except in any cases complicated by tumor and infection. The improved rate as scored on the Neurosurgical Cervical Spine Scale (NCSS) was on average 68.8%, and stable bone union was obtained in 13 cases in an average follow-up period 18.7-months (range of from 12 to 29 months), except in cases complicated by metastatic tumors. Postoperative complications included dyspnea (1 patient) and cerebrospinal fluid leakage treated by lumbar drainage (1 patient) without any additional repair operation. There were no hardware complications. This technique presents good clinical results and helps to avoid complications associated with harvesting bone from the iliac crest donor site.
