Study Design: This was a retrospective analysis. Background: Surgical decompression is the gold standard for preventing the progression of neurological deficit in degenerative multilevel cervical spondylotic myelopathy (CSM). The efficacy of posterior laminectomy in the surgical management of CSM has been described in the past, but long-term follow-up data are scanty. Objective: The aim of this study is to assess the long-term clinical-radiological outcomes following posterior cervical decompressive laminectomy in multilevel degenerative CSM. Materials and Methods: A retrospective analysis of 110 patients with degenerative multilevel CSM who underwent posterior cervical laminectomy alone in a single hospital by a single surgeon from 2009 to 2013 with minimum 5-year follow-up. Pre- and post-operative clinical parameters (visual analog scale [VAS], Nurick and modified Japanese orthopedic association [mJOA]), radiological parameter (Sagittal cervical Cobb's Angle), perioperative complications (time, blood loss, and hospital stay), postoperative complications (infection, C5 palsy, and neurological worsening) were evaluated. Results: Totally 110 patients (males – 68 and females – 42) with age varying from 46 to 80 (mean-57) years, and the mean duration of illness was 3 months were evaluated. Mean clinical parameters are VAS (preoperative = 5 ± 1.31, postoperative = 1.49 ± 0.687), Nurick grading (preoperative = 3.23 ± 71, postoperative = 1.924 ± 0.75), and mJOA (preoperative = 6.32 ± 0.87, postoperative = 9.89 ± 1.37). The mean blood loss was 93.95 ± 19.18 ml, and the mean time taken for surgery was 83.65 ± 10.18 min. About 13% (n = 15) patients developed cervical kyphosis and 29% (n = 32) developed changes in cervical spine alignment and 10% (n = 11) developed worsening of neurology at final follow-up. Two patients developed a superficial infection which was managed with antibiotics. Three patients developed C5 palsy which recovered with due time. Conclusions: With the proper selection of patients, posterior cervical laminectomy is effective in offering a clinical improvement to patients with degenerative multilevel CSM with a low incidence of clinically significant radiological deterioration.
