Abstract
OBJECTIVE: This study aimed to introduce anterior controllable antedisplacement fusion (ACAF), a new surgical technique, to treat multilevel cervical spondylotic myelopathy with spinal stenosis, compared with anterior cervical corpectomy and fusion (ACCF).
METHODS: From January 2016 to June 2017, patients with multilevel cervical spondylotic myelopathy with spinal stenosis (MCSMSS) who underwent ACAF (36 cases) and ACCF (45 cases) were enrolled in this study. Japanese Orthopedic Association (JOA) score was analyzed before the operation and at each time point during the follow-up after surgery to evaluate the neurologic function. Both clinical and radiologic outcomes, and perioperative complications were analyzed.
RESULTS: At the final follow-up, the mean JOA scores of the two groups were significantly improved compared with preoperative, respectively (P<0.01, P<0.01). However, the mean JOA scores between the two groups was not statistically significant (13.7±1.9 vs. 13.5±1.8; P=0.66). The operative duration was longer and the blood loss was higher in ACAF group than in ACCF group. The overall occurrence of complications in ACAF group was significantly lower than that in ACCF group (P<0.05).
CONCLUSIONS: ACAF has similar clinical and radiological outcomes and less complications compared with ACCF in the treatment of MCSMSS, and ACAF can be used as an alternative for cervical stenosis.
