经椎弓根短节段后路内固定(SSPI)骨水泥增强术(TCA)具有较好的即刻止痛效果和长期重建稳定性，被认为是治疗椎体骨坏死(ONV)手术策略的一大进步。方法回顾分析46例ONV患者，男22例，女24例，平均年龄62.87.11岁。结果36例患者完成了至少5年的随访期(平均随访期67+/-4.2个月)。发生并发症7例，分别为肺炎(2/36，5.56%)、螺钉松动(2/36，5.56%)、皮下组织中度血肿(1/36，2.78%)、骨水泥渗漏(2/36，5.56%)。术后6个月VAS平均评分较术前明显降低(P<0.05)。平均ODI得分显示出类似的趋势。术后平均后凸角和平均椎体高度均较术前明显矫正(P
BackgroundTranspedicular intracorporeal cement augmentation (TCA) with short segmental posterior instrumentation (SSPI), which provides an ideal immediate analgesic effect and long-term reconstructive stability, is thought to be a sensible advancement to the operative strategy in treating osteonecrosis of the vertebral body (ONV). However, long-term follow-up studies about the treatment are scarce.MethodsForty-six ONV patients (22 males and 24 females, mean age of 62.87.11years) underwent TCA with SSPI were retrospectively analyzed. During follow-up, clinical outcomes, such as the Visual Analogue Scale (VAS) score and the Oswestry Disability Index (ODI) score, were evaluated, as well as radiologic outcomes, such as the average vertebral height and kyphotic angle.ResultsA total of 36 patients completed a follow-up period of at least 5years (mean follow-up period of 67 +/- 4.2months). Among them, seven patients experienced complications, i.e., pneumonia (2/36, 5.56%), screw loosening (2/36, 5.56%), moderate hematoma in the subcutaneous tissue (1/36, 2.78%), and cement leakage (2/36, 5.56%). Compared to the preoperative score, the mean VAS score was significantly reduced 6months postoperatively (P0.05). The mean ODI score exhibited a comparable trend. Regarding the radiologic evaluation, the mean kyphotic angle and average vertebral body height were significantly corrected postoperatively (both P
