Abstract

Objective To explore the clinical effect of intertransverse bone grafting in the correction surgery for kyphosis deformity in ankylosing spondylitis (AS). Methods A retrospective analysis was conducted on 24 patients with AS combined with kyphosis who underwent posterior osteotomy correction and intertransverse process bone grafting from 2021 to 2023. The postoperative spinal parameters (GK, TK, LL, SVA, etc.), bone graft fusion rate, and complications were evaluated. Results The patients underwent the surgery smoothly and had good tolerance. The postoperative thoracic lordosis angle(55.50°±16.81°), lumbar lordosis angle (44.04°±13.77°), total spinal kyphosis angle (37.29°±17.42°), sagittal plane deviation [(5.49±3.87) cm] and other parameters exhibited statistically significant differences in comparison to the preoperative period (P<0.05). Subsequent follow-up of the patients revealed no substantial decline in the parameters of concern. The absence of complications, including but not limited to vascular and nerve injuries, as well as stress fractures, was noteworthy. The postoperative bone graft fusion rate was 91.6% (22/24), and there were no cases of internal fixation breakage. Conclusions Intertransverse bone grafting can effectively enhance spinal stability and reduce the risk of postoperative correction loss.
