Introduction: Laminoplasty is widely regarded as a safe and effective surgical treatment for cervical spine myelopathy (CSM) caused by spinal canal stenosis. Laminoplasty procedures for spinal cord decompression vary, but the majority of them necessitate the use of costly tools to support the laminae. We used the modified Z-plasty (Sakou's approach) for CSM patients from 2005 to 2015 in an attempt to lower treatment costs.
The purpose of this study is to look at Modified Z-Plasty for Cervical Spine Myelopathy. Our department of spinal surgery chose Z-laminoplasty for multilevel cervical stenosis since it did not require any pricey devices to anchor the laminae and had a favourable outcome.
The following are the materials and methods used in this retrospective investigation. Patients with CSM who had been treated with a modified Z-plasty approach were chosen. We used Sakou's approach, in which the laminae are alternately opened in opposite orientations. The JOA score and Hirabayashi recovery rate are used to assess neurological recovery, whereas the Neck Disability Index (NDI) is used to assess cervical functional outcome.
Results: 42 patients were followed for an average of 10 years (5-15 years), with a male to female ratio of 3:1 and an average age of 61. The average operating duration was 40 minutes, and the blood loss per lamina was 45 ml. The growing index of the canal was 4.2 mm (3-5 mm). The mean JOA score before and after surgery was 11.1 and 14.7, respectively (p0.05). The mean NDI for axial discomfort was 18 points, with 88 percent of subjects having good or excellent cervical function. There were three occurrences of C5 palsy as a result of the problems, all of which recovered completely within a year.
Conclusion: Although the modified Z-plasty is regarded an old-fashioned operation, it can nevertheless yield satisfactory clinical and radiological outcomes for cervical myelopathic patients. The absence of hardware such as titanium plates or hydroxyapatite spacers minimises infection risk and treatment costs. This operation is suited for low-income patients in developing nations, based on the risk-benefit and cost-benefit ratios.Author(S) Details
