重建M形钢板修复骨盆后环损伤的稳定性

背景：骨盆后环损伤后精确的复位和稳定的固定与术后功能状况密切相关。目的：探讨M形钢板在骨盆后环损伤中的临床应用价值。方法：回顾性分析32例采用后路M形钢板固定方法治疗骨盆后环损伤的病例资料，其中男22例，女10例，年龄18~51岁。Matta标准评定骨折复位情况，Majeed 评分系统评估内固定后功能。结果与结论：内固定时间平均1.5 h，置入过程中出血80~300 mL，所有患者无神经损伤及感染，切口均一期愈合，均获得随访，随访时间8~36个月。内固定后复位Matta评定：优24例，良6例，可2例，优良率93.8%。Majeed 功能评分：优20例，良8例，可4例，优良率87.5%。提示M形钢板通过解剖塑形与骨盆后环有效贴附固定，具有稳定性好、操作简单、手术时间短、创伤小、出血少、并发症少等特点。

M-shaped plate fixation for posterior pelvic ring injury: A stability study

BACKGROUND: Accurate reduction and stable fixation after posterior pelvic ring injury are closely related to postoperative functional status.OBJECTIVE: To investigate the clinical experience that M-shaped plate fixation for injuries at the posterior ring of the pelvis. METHODS: The clinical data of 32 cases with posterior pelvic ring injury undergoing M-shaped plate were analyzed retrospectively. There were 22 males and 10 females, at age range of 18-51 years (mean 34.5 years). Fracture reduction was evaluated by Matta criterion and function was evaluated by Majeed functional scoring. RESULTS AND CONCLUSION: The average intraoperative time was 1.5 hours (ranging from 1 to 2 hours), and the average intraoperative blood was 190 mL (ranging from 80 to 300 mL). There was no iatrogenic nerve injury and all the incisions healed during the primary procedure. All the patients were available at follow-up, with a mean period of 22 months (ranging from 8 to 36 months). According to Matta criterion for fracture reduction, the results were excellent in 24 patients, good in 6 and fair in 2, with excellence rate of 93.8%. According to the Majeed functional scoring, the results were excellent in 20 patients, good in 8 and fair in 4, with excellence rate of 87.5%. M-shaped plate fixation for posterior pelvic ring injury has the advantages of broad indications, simplicity of operator, short intraoperative time, small trauma, less bleeding, fewer complications, and significant clinical efficacy, which is worth spreading.
