Abstract
OBJECTIVE: To investigate the effectiveness of stand-alone MC+polyether-ether-ketone (PEEK) Cage (single blade type) in anterior cervical double-level fusion for more than 2 years follow-up. METHODS: A clinical data of 30 patients who were treated with anterior cervical fusion surgery with stand-alone MC+PEEK Cage (single blade type) between January 2013 and December 2016 and followed up for more than 2 years, was retrospectively analyzed. There were 16 males and 14 females, aged from 34 to 72 years with an average of 52.2 years. There were 16 cases of cervical spondylotic myelopathy, 8 cases of cervical spondylotic myelopathy, and 6 cases of traumatic cervical disc herniation. The continuous double segments were C 4, 5, C 5, 6 in 12 cases and C 5, 6, C 6, 7 in 18 cases; and the disease duration ranged from3 days to 24 months (mean, 12 months). Postoperative neck hematoma and wound healing were observed; dysphagia was assessed by Bazaz system; and bone fusion was assessed by Suk method. Before operation, at 1 week after operation, and at last follow-up, the Japanese Orthopaedic Association (JOA) score was used to evaluate the neurological recovery; the cervical X-ray film was performed to record the cervical curvature (C 2-C 7 Cobb angle), the height of the intervertebral space of the fusion segment, and to judge the occurrence of the fusion Cage subsidence. RESULTS: No complication such as neck hematoma, incision infection, or esophageal fistula was found, primary healing of incisions was obtained in all cases. All patients were followed up 24-72 months (mean, 46 months). Neurological symptoms such as limb numbness and pain gradually disappeared after operation; during the follow-up period, the cervical curvature could be effectively maintained; dysphagia and internal fixation related complications such as displacement of Cages were not found. All patients obtained bony fusion from 3 to 8 months with an average time of 4.3 months. Compared with preoperative ones, the JOA score, intervertebral space height, and Cobb angle of cervical spine were significantly improved at 1 week after operation and at last follow-up ( P<0.05), but there was no significant difference between 1 week after operation and last follow-up ( P>0.05). CONCLUSION: The application of stand-alone MC+PEEK Cage (single card type) in anterior cervical fusion can provide early cervical stability, effectively maintain the physiological curvature of cervical spine and the height of fusion intervertebral space.
