To evaluate the efficacy of percutaneous uniplanar pedicle screw (PUPS) combined with injured vertebra fixation for treating thoracolumbar burst fracture and provide technique notes.
A descriptive study.
Department of Orthopaedics, General Hospital of Central Theater Command, Wuhan, China, from February 2019 to December 2021.
Patients who had undergone PUPS internal fixation for thoracolumbar burst fracture were followed up for more than 12 months in the General Hospital of Central Theater Command, Wuhan, China. The operation time, intraoperative blood loss, and hospital stay were recorded. Visual analysis scale (VAS), score of low back pain, ODI (oswestry disability endex), anterior vertebral height (AVH), Cobb angle were documented before and after the operation, Also, the complications and postoperative tail shank angles (TSA) were documented.
All 23 patients were followed up for more than 12 months without re-fracture, loosening or breakage of the screw and rod. The operation time, intraoperative blood loss, and hospital stay were 51.34±8.30 minutes, 75.67±16.55 minutes, and 9.86±1.96 days respectively. VAS and ODI scores after the operation were significantly lower than before (p <0.05). The AVH and Cobb angle after operation were significantly better as compared with those before the operation (p <0.05), but no statistically significant difference was found in those two values at 1 week, 3 months, and 12 months after operation (p >0.05). No statistically significant difference was found in TSA after the operation (p >0.05).
PUPS combined with injured vertebra fixation reveals satisfactory efficacy for thoracolumbar burst fracture with well reduction of the fracture, the AVH, and Cobb angle maintenance.

评估经皮单平面椎弓根螺钉（PUPS）联合伤椎固定治疗胸腰椎爆裂骨折的疗效并提供技术要点。
描述性研究。
中国武汉中部战区总医院骨科，2019年2月至2021年12月。
在中国武汉中部战区总医院对接受PUPS内固定治疗胸腰椎爆裂骨折的患者进行了超过12个月的随访。记录手术时间、术中出血量和住院时间。记录术前和术后的视觉模拟评分（VAS）、腰痛评分、Oswestry功能障碍指数（ODI）、椎体前缘高度（AVH）、Cobb角。此外，记录并发症和术后尾椎角（TSA）。
23例患者均获随访超过12个月，未出现螺钉和棒的再骨折、松动或断裂。手术时间、术中出血量和住院时间分别为51.34±8.30分钟、75.67±16.55分钟和9.86±1.96天。术后VAS和ODI评分显著低于术前（p<0.05）。术后AVH和Cobb角与术前相比明显改善（p<0.05），但术后1周、3个月和12个月这两个值差异无统计学意义（p>0.05）。术后TSA差异无统计学意义（p>0.05）。
PUPS联合伤椎固定治疗胸腰椎爆裂骨折疗效满意，骨折复位良好，AVH和Cobb角得以维持。
