Abstract

Background

The debate surrounding the influence of the open Latarjet procedure on postoperative scapular motions persists, and there is no evidence regarding its effects on periscapular muscle activation. This study aimed to assess the short-term influence of the open Latarjet procedure on scapular kinematics and periscapular muscle activity during arm raising and lowering based on comparisons between patients and healthy athletes.

Methods

22 healthy male athletes and 22 male athletes scheduled for glenohumeral stabilization surgery by the open Latarjet procedure were included. Scapular kinematics, periscapular muscle activities, and shoulder-related quality of life were recorded before surgery and 3 months postoperatively for the Latarjet group. For the healthy group, same assessments were performed 3 months apart. Bilateral differences in both scapular kinematics and periscapular muscle activation ratios and the Western Ontario Shoulder Instability (WOSI) index were defined as dependent variables.

Results

Scapular kinematics of the operated shoulder, namely scapular upward/downward rotation, internal/external rotation, and anterior/posterior tilt recorded between 20° and 120° of humerothoracic elevation, showed no alterations 3 months after surgery (P > .05) and did not differ from those observed in healthy athletes (P > .05). Similarly, all periscapular muscle activations were not different within time and between groups (P > .05). The WOSI index of the operated shoulder was significantly improved postoperatively (871.9 ± 443.7 vs. 1346.3 ± 552.3) but remained higher than the WOSI indices of the nonoperated shoulder or those of the healthy group (52.7 ± 75.6).

Conclusions

This study emphasizes the short-term effects of the open Latarjet procedure, demonstrating an improvement in the shoulder-related quality of life 3 months after surgery. Notably, during this period, both kinematics and periscapular muscle activity remained consistent and similar to the patterns observed for healthy athletes.

开放式 Latarjet 手术对术后三个月肩关节运动学和肩胛周围肌肉活动的影响。

背景：围绕开放式Latarjet手术对术后肩胛骨运动的影响的争论一直存在，而关于其对肩胛周围肌肉激活的影响却没有证据。本研究旨在通过对患者和健康运动员进行比较，评估开放式Latarjet手术在手臂抬起和放下时对肩胛骨运动学和肩胛周围肌肉活动的短期影响。在手术前和术后3个月，对Latarjet组的肩胛运动学、肩胛周围肌肉活动和肩部相关生活质量进行记录。对于健康组，同样的评估在术后3个月进行。双侧肩胛骨运动学和肩胛周围肌肉激活率的差异以及西安大略省肩关节不稳定（WOSI）指数被定义为因变量：手术后3个月，肩胛骨运动学，即肩胛骨上/下旋转、内/外旋转和前/后倾斜，在肱骨胸廓抬高20°至120°之间的记录没有变化（P>0.05），与健康运动员的记录也没有差异（P>0.05）。同样，所有肩胛周围肌肉的激活在不同时间和不同组别之间也没有差异（p>0.05）。手术组肩关节的 WOSI 指数在术后明显改善（871.9 ± 443.7 vs. 1346.3 ± 552.3），但仍高于未手术组或健康组的 WOSI 指数（52.7±75.6）：本研究强调了开放式Latarjet手术的短期效果，表明术后3个月肩部相关生活质量有所改善。值得注意的是，在此期间，运动学和肩胛周围肌肉活动均保持一致，与健康运动员的活动模式相似。

期刊介绍： The official publication for eight leading specialty organizations, this authoritative journal is the only publication to focus exclusively on medical, surgical, and physical techniques for treating injury/disease of the upper extremity, including the shoulder girdle, arm, and elbow. Clinically oriented and peer-reviewed, the Journal provides an international forum for the exchange of information on new techniques, instruments, and materials. Journal of Shoulder and Elbow Surgery features vivid photos, professional illustrations, and explicit diagrams that demonstrate surgical approaches and depict implant devices. Topics covered include fractures, dislocations, diseases and injuries of the rotator cuff, imaging techniques, arthritis, arthroscopy, arthroplasty, and rehabilitation.
