OBJECTIVETo investigate the clinical outcomes of anterior corpectomy combined with anterior intervertebral decompression and fusion for multilevel cervical spondylotic myelopathy.

METHODSThe clinical data of 28 patients with multilevel cervical spondylotic myelopathy who underwent surgery from October 2012 to June 2014 were retrospectively analyzed. There were 18 males and 10 females, aged from 45 to 77 years old with an average of (60.11±9.37) years. Three levels were involved in 27 cases, while four levels were involved in 1 case. The preoperative JOA score was 8.89±1.87; the fusion segments angles was (4.87±4.56)°; and the cervical curvature was (11.68±1.25)°. Anterior hybrid decompression and fusion were performed in 28 patients. The fusion segments angles and the cervical curvature were assessed by X-rays at 1, 12 months after operation, respectively. JOA score was used to evaluate the clinical effect.

RESULTSThe operative time was 163 min on average (ranged from 120 to 205 min), and intraoperative bleeding was 198 ml on average(ranged from 100 to 300 ml). Hoarseness occurred in 1 case and got recovery at 3 weeks after operation and choke cough occurred in 1 case, and got improvement at 1 week after operation. All the patients were regularly followed for 12-24 months with an average of(18.46±3.20) months. Graft bone obtained fusion at 12 months after operation and the position of internal fixation was good. The fusion segments angles, the cervical curvature and JOA scores were significantly improved at 1, 12 months after operation(<0.05). The improvement rate of JOA score was(46.46±20.26)% at 12 months after operation, 12 cases got excellent results, 14 good and 2 fair.

CONCLUSIONSAnterior corpectomy combined with anterior intervertebral decompression and fusion is safe and effective and can get satisfactory effects for multilevel cervical spondylotic myelopathy.
