Abstract：
OBJECTIVE: This study aimed to investigate the causes of lumboperitoneal (LP) shunt failure and determine risk factors for lumbar catheter fracture.
METHODS: We retrospectively investigated 149 patients who underwent LP shunting in our hospital between January 2012 and March 2023. Shunt reconstruction occurred in 22 patients (14.8%). Among these, cause of failure was lumbar catheter fracture in 5 (22.7%). Patient backgrounds, cause of LP shunt failure, surgical technique factors, and anatomical characteristics were extracted for comparative analysis and risk factors of lumbar catheter fracture were analyzed.
RESULTS: Compared with the no reoperation group (n = 127), patients in the lumbar catheter fracture tended to be younger (63 ± 20 vs. 72 ± 11 years) and favorable neurologic status (modified Rankin scale score ≤2) after initial LP shunt; however, the differences were not significant. Lumbar lordosis was significantly higher in the lumbar catheter fracture group (52.7°± 14.8° vs. 37.1°± 12.3°; P = 0.0067).
CONCLUSIONS: Excessive lumbar lordosis is a risk factor for lumbar catheter fracture in patients undergoing LP shunting. Younger age and higher level of postoperative activities of daily living might also be associated with lumbar catheter fracture.

摘要：
目的：本研究旨在探讨腰腹膜（LP）分流失败的原因并确定腰椎导管骨折的危险因素。
方法：我们回顾性调查了在2012年1月至2023年3月期间在我们医院接受LP分流的149例患者。分流重建22例(14.8%)。其中,失败的原因是5例(22.7%)的腰椎导管骨折。患者背景,低压分流故障的原因,手术技术因素，提取解剖学特征进行对比分析,分析腰椎导管骨折的危险因素。
结果：与未再手术组（n=127）相比，腰椎导管骨折患者趋于年轻（63±20vs.初次LP分流后72±11年）和良好的神经系统状况（改良的Rankin量表评分≤2）；但是差异不显着。腰椎导管骨折组腰椎前凸明显增高（52.7°±14.8°vs.37.1°±12.3°;P=0.0067)。
结论：腰椎前凸过度是LP分流患者腰椎导管骨折的危险因素。年龄较小和术后日常生活活动水平较高也可能与腰椎导管骨折有关。
