STUDY DESIGN: Retrospective cohort analysis.
OBJECTIVE: The purpose of this study is to investigate whether the removal of the posterior longitudinal ligament (PLL) affects the mid-term outcome of anterior cervical fusion for cervical spondylosis with sympathetic symptoms(CSSS).
METHODS: From January 2012 to July 2013, 66 patients who were diagnosed with CSSS with ≥ 10-year follow-up at our institution were assessed. All patients were divided into two groups: Group A (36 cases) in which patients underwent anterior cervical fusion with PLL resection and Group B (30 cases) in which patients underwent anterior cervical fusion without PLL resection. The sympathetic symptom 20-point system was used to evaluate the sympathetic symptoms, such as tinnitus, headache and vertigo, etc. And the neurological status was assessed by the Japanese Orthopedic Association (JOA) scores. Clinical and radiologic data were evaluated preoperatively, 9 days, 3 months, 6 months, 12 months, 24 months, 60 months, and 120 months postoperatively. Data collected included all perioperative complications as morbidities that occurred during the period of follow-up.
RESULTS: The postoperative JOA scores and 20-point score can be significantly improved compared with preoperative whether the PLL is removed in both groups. However, the postoperative 20-point score of patients in group A was significantly different from that in group B. No loosening and displacement of prosthesis occurred.
CONCLUSION: A better clinical effect could be attained when resecting the PLL in the operation. The PLL may play an important role in CSSS. The mid-term outcomes of anterior cervical fusion with PLL resection were satisfied in treating CSSS.
