Objectives: 

To examine clinical gait parameters, hip muscle strength, pelvic functional outcomes, and psychological outcomes after surgical fixation of OTA/AO 61-B and 61-C pelvic ring injuries.

Design: 

Retrospective review identified 10 OTA/AO 61-B patients and 9 OTA/AO 61-C patients for recruitment who were between 1 and 5 years after pelvic fixation. Gait and strength assessments, and patient-reported outcome scores were performed/collected and analyzed.

Setting: 

Outpatient clinical motion performance laboratory.

Patients/Participants: 

Patients with OTA/AO 61-B and OTA/AO 61-C fractures who were between 1 and 5 years after pelvic fixation.

Main Outcome Measurements: 

Hip strength, kinetics, and spatial–temporal outcomes; Majeed Pelvic Outcome Score; Short Form 36; Hamilton Anxiety/Depression Rating Scales.

Results: 

There were no differences in age, body mass index, or time since definitive fixation between OTA/AO 61-B and 61-C groups. The OTA/AO 61-C group had higher median injury severity scores, longer length of stay, and greater postoperative pelvic fracture displacement. There was no difference in bilateral hip strength, bilateral peak hip moments, peak hip power, and walking speed between groups. Patients with OTA/AO 61-C fractures had lower scores on Short Form 36 General Health and Majeed Work, with a trend toward a lower Total Majeed score. There were no differences in self-reported total anxiety and depression symptoms.

Conclusions: 

This study did not identify any gait, strength, or psychological differences between OTA/AO 61-B and 61-C injuries at 1–5 years of follow-up. However, increased injury severity in OTA/AO 61-C patients may have residual consequences on perceived general health and ability to work. This pilot study establishes a template for future research into functional recovery of patients with severe pelvic ring trauma.

Level of Evidence: 

Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

OTA/AO 61-B 和 61-C 骨盆环损伤后的术后步态、髋部力量和患者报告的结果分析

目标： 

检查OTA/AO 61-B 和 61-C 骨盆环损伤手术固定后的临床步态参数、髋部肌肉力量、骨盆功能结果和心理结果。

设计： 

回顾性审查确定了 10 名 OTA/AO 61-B 患者和 9 名 OTA/AO 61-C 患者在骨盆固定后 1 至 5 年内招募。进行/收集和分析步态和力量评估以及患者报告的结果评分。

环境： 

门诊临床运动性能实验室。

患者/参与者： 

骨盆固定后 1 至 5 年的 OTA/AO 61-B 和 OTA/AO 61-C 骨折患者。

主要成果测量： 

髋部力量、动力学和时空结果；Majeed 骨盆结果评分；简表 36；汉密尔顿焦虑/抑郁评定量表。

结果： 

OTA/AO 61-B 和 61-C 组之间的年龄、体重指数或自最终固定后的时间没有差异。OTA/AO 61-C 组的中位损伤严重程度评分更高，住院时间更长，术后骨盆骨折移位更大。组间双侧髋部力量、双侧髋部峰值力矩、峰值髋部功率和步行速度无差异。OTA/AO 61-C 骨折患者在 Short Form 36 General Health 和 Majeed Work 上的得分较低，总 Majeed 得分呈较低趋势。自我报告的总焦虑和抑郁症状没有差异。

结论： 

这项研究在 1-5 年的随访中没有发现 OTA/AO 61-B 和 61-C 损伤之间的任何步态、力量或心理差异。然而，OTA/AO 61-C 患者的损伤严重程度增加可能会对感知的总体健康和工作能力产生残余影响。这项初步研究为未来研究严重骨盆环外伤患者的功能恢复建立了一个模板。

证据等级： 

预后等级 III。有关证据级别的完整描述，请参见作者说明。
