BACKGROUND/AIM: Open surgical reduction/fixation of thoracolumbar fractures results in significant soft-tissue trauma and related complications. Minimally-invasive technical developments could deliver similar radiological outcomes, while avoiding the related complications. We evaluated radiological and perioperative outcomes in thoracolumbar fractures by using a novel minimally-invasive device.
PATIENTS AND METHODS
Twenty-six patients with 29 thoracolumbar fractures using the NForce device were analyzed. Postoperative reduction and alignment were assessed by radiographic measurement of the local kyphosis angle (LKA) up until a follow-up period of 9 months.
RESULTS
Postoperative imaging revealed an average reduction of traumatic kyphosis of 8.25° (±7.72°) with an average postoperative LKA of 3.24° (±8.97°). The highest degree of reduction was 27.39°. The mean LKA had increased to 5.08° (±5.17°) at 3 months postoperative, 5.43° (±4.32°) at 6 months and 6.21° (±3.82°) at 9 months.
CONCLUSION
The minimally invasive NForce system is effective in performing anatomic percutaneous reduction/fixation.
背景/目的：开放式手术复位/固定胸腰椎骨折会导致明显的软组织创伤和相关并发症。微创技术的发展可以带来类似的影像学结果，同时避免相关并发症。我们使用一种新型微创器械评估胸腰椎骨折的影像学和围手术期结果。
患者和方法
分析了 26 例使用 NForce 装置的 29 例胸腰椎骨折患者。通过局部后凸角（LKA）的放射学测量评估术后复位和对线，随访时间直至 9 个月。
结果
术后影像学显示创伤后后凸畸形平均矫正 8.25°（±7.72°），术后 LKA 平均为 3.24°（±8.97°）。最大矫正度数为 27.39°。术后 3 个月 LKA 平均增加至 5.08°（±5.17°），术后 6 个月增加至 5.43°（±4.32°），术后 9 个月增加至 6.21°（±3.82°）。
结论
微创 NForce 系统在进行解剖经皮复位/固定方面是有效的。
