Decompressive Cervical Laminectomy and Lateral Mass Screw-Rod Fusion for Multisegmental Cervical Spondylotic Myelopathy with Flexible Sagittal Cervical Alignment

Background data: Posterior cervical laminectomy and lateral mass screw-rod fusion techniques were classically recommended in flexible sagittal alignment relying on indirect decompression via posterior cord shift. Purpose: This study aims to investigate the efficacy of with fixation for treating multisegmental spondylotic myelopathy alignment. Study Design: Prospective clinical cohort study. Patients Methods: In total, 38 patients clinically symptomatic M-CSM instability and/or kyphosis admitted our Zagazig university hospitals (long-segment instrumented ≥3 segments) completed 24-month follow-up period between April 2014 June 2018 last visit took place October 2020. categorized into lordotic, straight, kyphotic groups according shape spine curve a neutral X-ray view. Results: A total 266 screws inserted 134 levels (3 20 patients, 4 16 5 2 patients), all had good fusion, was stable, based absence hardware failure or subsidence. All (100%) gained more lordosis variable degree preoperative The mean percentage neck pain improvement Visual Analogue Scale (VAS) lordotic group 69.1%, straight 43.8%, 15.8%. neurological function (JOA score) 83.17%, 43%, 17%. disability (NDI 47.66%, 24.5%, 16.66%. Conclusion: Decompressive screw stabilization is effective (2022ESJ259)
