Study Design: 

Prospective review.

Objective: 

The aim was to assess the efficacy and safety of short-segment pedicle fixation of low lumbar fractures (L3–L5).

Background: 

Low lumbar fractures are relatively uncommon, and limited data exists regarding the management of these injuries. No previous studies have specifically examined the surgical management of L3–L5 fractures exclusively with pedicle fixation.

Materials and Methods: 

We reviewed prospectively collected data of 36 patients who underwent short-segment pedicle fixation for low lumbar fractures at our institution between 1993 and 2018.

Results: 

There was no worsening of neurological status following surgery, and three patients regained motor or sphincter function. Thirty-one (86.1%) patients went on to successful fusion. Three (8%) patients required reoperation. Four (11%) patients had surgical complications.

Conclusions: 

This large series provides information regarding the safety and efficacy of surgical management of low lumbar fractures with pedicle fixation. Following surgery, there was no neurological worsening and some patients regained neurological function. Low complication rates, low reoperation rates, and low pain levels at final follow-up provide evidence that the surgical management of low lumbar fractures utilizing short-segment pedicle fixation is safe and efficacious.

外伤性低位腰椎骨折（L3～L5）短节段椎弓根内固定术36例报告

学习规划： 

前瞻性审查。

客观的： 

目的是评估短节段椎弓根固定治疗低位腰椎骨折（L3-L5）的有效性和安全性。

背景： 

低位腰椎骨折相对罕见，并且有关这些损伤处理的数据有限。之前没有研究专门检验仅采用椎弓根固定的 L3-L5 骨折的手术治疗。

材料和方法： 

我们回顾了 1993 年至 2018 年间在我们机构因低位腰椎骨折接受短节段椎弓根固定的 36 名患者的前瞻性数据。

结果： 

手术后神经状态没有恶化，三名患者恢复了运动或括约肌功能。三十一名 (86.1%) 患者成功融合。三名（8%）患者需要再次手术。四名 (11%) 患者出现手术并发症。

结论： 

这个大型系列提供了有关椎弓根固定手术治疗低位腰椎骨折的安全性和有效性的信息。手术后，神经功能没有恶化，一些患者恢复了神经功能。低并发症率、低再手术率和最终随访时的低疼痛水平证明，利用短节段椎弓根固定术治疗低位腰椎骨折是安全有效的。
