Abstract
OBJECTIVE: To explore the clinical efficacy and safety of microscopy-assisted anterior corpectomy and fusion for cervical ossification of the posterior longitudinal ligament (OPLL).
METHODS: A retrospective review of 32 cervical OPLL patients who underwent microscopy-assisted anterior corpectomy and fusion from June 2012 to March 2017 was carried out. Patients were evaluated with outcome metrics: Japanese Orthopaedic Association (JOA) scores (17 points method), visual analog scale (VAS), and radiographic parameters of the lordotic angle. The complications during treatment and follow-up were recorded.
RESULTS: This study included 32 patients (15 males and 17 females) with a mean age of 58.3 ± 2.9 years (range 42-68 years). The average duration of follow-up was 19.0 ± 3.5 months (range 11-46 months). The scores of postoperative VAS significantly decreased (P < 0.05). The average JOA score at 12 months postoperation significantly improved (p < 0.05). The lordotic angle increased after surgery (P < 0.05). There was no titanium mesh subsidence, no pseudarthrosis or hardware failure at 1‑year follow-up.
COMPLICATIONS: One cerebrospinal fluid leakage in the surgery was managed using a gelatine sponge and the patient recovered after 1 week: One patient developed laryngeal nerve injury symptom of hoarseness and recovered spontaneously in 2 weeks without intervention and 1 patient suffered slight postoperative infection. There was no worsening of neurological function.
CONCLUSION: Microscopy-assisted anterior cervical anterior surgery appears to be a safe and effective treatment option for selected cases of cervical posterior longitudinal ligament ossification.
