Abstract:
Background: To explore the correlation between body mass index (BMI) and the incidence of axial symptoms after cervical laminoplasty. Methods: A retrospective review of cases who passed cervical open-door laminoplasty secured with titanium miniplates fixation and no bone grafting in our hospital from January 2020 to September 2020 was performed. According to the obesity classification in China1, 30 patients were overweight (BMI≥24kg/m2), and 36 were not non-overweight (BMI＜24kg/m2). Blood loss during surgery, operative time, hospitalization time, visual analog scale scores (VAS) postoperatively, Japanese Orthopedic Association (JOA) scores preoperatively and postoperatively, and cervical alignment were evaluated. Results: The overweight group's operative time was longer than the non-overweight group's (P＜0.05), but the amount of blood loss during the operation was not different (t=-1.281, P＞0.05). The hospitalization time of the overweight group was longer than the non-overweight group’s (P＜0.05). The VAS score of the overweight group was significantly higher on post-operative day 1 and day 3 P＜0.05; P＜0.05). There’s no significant difference in pre- and post-operative JOA scores or Cobb angles (pre-operatively and 1 month post-operatively) between the two groups (P>0.05; P>0.05). Conclusion: After cervical expansive single-door laminoplasty secured with mini plates, higher BMI had more severe axial symptoms in the postoperative period than the non-overweight group.
