Abstract

Purpose

Greater trochanteric pain syndrome (GTPS) is a condition resulting in lateral hip pain, most commonly caused by tendinosis or tear of the gluteus medius and minimus tendons, and greater trochanteric bursitis. Our aim was to assess pelvic parameters and proximal femoral anatomy in patients suffering from surgical-stage GTPS compared with a control group.

Methods

This retrospective, case-control study assessed 43 patients suffering from GTPS, matched according to age, gender, body mass index and level of sport and physical activity to 43 control patients, between 2013 and 2018. Pelvic parameters, including pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS), and proximal femoral anatomy, including femoral offset (FO) and neck-shaft angle (NSA), were measured using the EOS Imaging™ system.

Results

GTPS patients had a significantly lower mean (± SD) SS than control patients (33.1 ± 10.4 vs. 39.6 ± 9.7°, respectively; p < 0.05). There was no significant difference in PT (21.3 ± 7.1 vs. 19.0 ± 7.2°), PI (53.5 ± 11.6 vs. 57.7 ± 10.5°), FO (40.4 ± 8 vs. 42.2 ± 6.8°) or NSA (125.1 ± 5.8 vs. 124.4 ± 4.7°). There was no difference in lower back pain symptoms in a subgroup analysis of GTPS patients.

Conclusions

Sacral slope was lower in patients with surgical-stage GTPS than in asymptomatic hip patients, using the EOS Imaging™ system.

大转子转子疼痛综合征的脊髓盆腔参数：一项回顾性病例对照研究

摘要

目的

大转子转子疼痛综合征（GTPS）是一种导致外侧髋部疼痛的疾病，最常见的原因是臀中肌和小肌腱的肌腱病或撕裂，以及大转子转子囊炎。我们的目的是评估与对照组相比手术阶段GTPS患者的骨盆参数和股骨近端解剖。

方法

这项回顾性病例对照研究评估了43名患有GTPS的患者，根据年龄，性别，体重指数以及运动和体育锻炼的水平，在2013年至2018年之间对43名对照患者进行了匹配。骨盆参数，包括骨盆发生率（PI） ，骨盆倾斜（PT）和骨倾斜（SS）以及股骨近端解剖结构，包括股骨偏移（FO）和颈轴角（NSA），均使用EOS Imaging™系统进行了测量。

结果

GTPS患者的平均（±SD）SS显着低于对照组患者（分别为33.1±10.4和39.6±9.7°；p  <0.05）。PT（21.3±7.1 vs. 19.0±7.2°），PI（53.5±11.6 vs. 57.7±10.5°），FO（40.4±8 vs.42.2±6.8°）或NSA（125.1±5.8）没有显着差异vs. 124.4±4.7°）。在GTPS患者的亚组分析中，下背部疼痛症状无差异。

结论

使用EOS Imaging™系统，手术阶段GTPS患者的patients骨斜率低于无症状髋关节患者。
