摘要
OBJECTIVE: To compare the change in cervical range of motion (CROM) after the 2 most widely used techniques for multilevel cervical spondylotic myelopathy (CSM): anterior cervical corpectomy and fusion (ACCF) and laminoplasty. METHODS: Patients with multilevel CSM treated in our hospital between 2014 and 2018 were divided into an ACCF group and a laminoplasty (LAMP) group according to the treatment received. Their demographic data, preoperative and postoperative Japanese Orthopedic Association (JOA) scores, and CROM, measured using the Coda Motion system, were analyzed and compared. RESULTS: A total of 53 patients were enrolled, including 29 patients in the ACCF group and 24 patients in the LAMP group. Age, sex, duration of follow-up, and preoperative and postoperative JOA scores were comparable in the 2 groups. Compared with preoperative measurements, ACCF group lost an average of 9.8%, 28.5%, 8.9%, 9.9%, 10.6%, and 7.8% of their CROM in flexion, extension, left and right lateral flexion, and left and right rotation, respectively, at the latest follow-up. For the LAMP group, these average losses were 3.5%, 16.4%, 3.2%, 6.3%, 7.0%, and 5.7%, respectively. Thus, the ACCF group exhibited greater average CROM loss than the LAMP group in all directions at the latest follow-up. CONCLUSIONS: Both ACCF and laminoplasty cause significant CROM loss in patients with multilevel CSM. The laminoplasty technique preserved more CROM than ACCF in all 6 directions after at least 1 year of follow-up. These results can be used when counseling patients undergoing surgery.
