BACKGROUND To compare the clinical and radiological outcomes between posterior mono-segment and short-segment fixation combined with one-stage posterior debridement and bone grafting fusion in treating single-segment lumbar spinal tuberculosis (LSTB). METHODS Sixty-two patients with single-segment LSTB treated by a posterior-only approach were divided into two groups: short-segment fixation (Group A, n = 32) and mono-segment fixation (Group B, n = 30). The clinical and radiographic outcomes were analyzed and compared between the two groups. RESULTS The intraoperative bleeding volume, operation time, and hospitalization duration were lower in Group B than in Group A. All patients achieved the bony fusion criteria. The visual analog scale score, Japanese Orthopedic Association score, and Oswestry Disability Index were substantially improved 3 months postoperatively and at the last visit in both groups, with no significant difference between the two groups (P > 0.05). Kirkaldy-Willis functional evaluation at the final follow-up demonstrated that all patients in both groups achieved excellent or good results. The difference in the angle correction rate and correction loss between Groups A and B was not significant (P > 0.05). CONCLUSIONS One-stage posterior debridement, bone grafting fusion, and mono-segment or short-segment fixation can provide satisfactory clinical and radiological outcomes. Mono-segment fixation is more suitable for the treatment of single-segment LSTB because the lumbar segments with normal motion can be preserved with less trauma, a shorter operation time, shorter hospitalization, and lower costs.

单节段腰椎结核的一期后路清创、植骨融合以及单节段与短节段固定：至少 5 年随访结果。


背景 比较后路单节段和短节段固定联合一期后路清创植骨融合治疗单节段腰椎结核（LSTB）的临床和影像学结果。方法 将 62 例仅后路入路治疗的单节段 LSTB 患者分为两组：短节段固定（A 组，n = 32）和单节段固定（B 组，n = 30）。分析并比较两组的临床和影像学结果。结果B组术中出血量、手术时间、住院时间均低于A组，所有患者均达到骨性融合标准。两组患者术后3个月及末次访视时视觉模拟量表评分、日本骨科协会评分、Oswestry功能障碍指数均有明显改善，但两组间差异无统计学意义（P>0.05）。最终随访时的 Kirkaldy-Willis 功能评估表明，两组患者均取得了优异或良好的结果。 A、B组角度矫正率和矫正损失差异无显着性（P>0.05）。结论 一期后路清创、植骨融合和单节段或短节段固定可提供满意的临床和放射学结果。单节段固定更适合单节段LSTB的治疗，因为可以保留正常运动的腰椎节段，创伤小，手术时间短，住院时间短，费用低。
