Outcome of Laminoplasty in Patients with Multilevel Cervical Myelopathy

Abstract

Objective: To determine the outcome of surgical intervention in the form of laminoplasty in the patients with multilevel cervical myelopathy. Material and Methods: Descriptive case series, was conducted at NS-I, PINS, Lahore for 6 months. The patients were included through non probability consecutive sampling that fulfilled inclusion criteria. All of the patients were assessed using JOA score before and after 2 months of surgery. General characteristics, including age, gender, other medical conditions and other risk factors were assessed prior to surgery. The total number of 35 patients was included with expected JOA percentage recovery rate of 75% + 21% after the procedure. Results: In this study 35 total patients were enrolled. The mean age was 55.68 + 9.92 years. Total number of male patients were 23 (65.71), while the female was 12 (34.29). The mean duration of degenerative cervical myelopathy was 3.90 + 1.3 months. The mean pre op value of JOA score was 7.08 + 2.7 (4 – 10) for the patients. The mean post op score was 13.00 + 2.30 (9 – 17). The mean recovery value calculated at two month interval was 62.12 + 17.39 (38.46 – 100). Statistically, there was a significant difference of outcome of pre and post op value of JOA scores i.e., p value = 0.00. Conclusion: Our study determined that, the open door laminoplasty is an effective and reliable technique with good outcome in the treatment of multi-level degenerative cervical spine myelopathy patients.
