Abstract

Background

Although it is considered a sensitive indicator of shoulder disabilities, the scapulohumeral rhythm has not been investigated after anterior glenohumeral stabilization with open Latarjet procedure. This study aimed to assess the short-term influence of glenohumeral stabilization on scapulohumeral rhythm in patients who underwent open Latarjet procedure compared to asymptomatic individuals.

Methods

A group of male patients who underwent anterior glenohumeral stabilization by open Latarjet procedure and a healthy group were enrolled in this study. An electromagnetic device was used to record scapulothoracic and glenohumeral joint kinematics during dynamic arm elevation and depression in the scapular plane before and three months after surgery. Then, the three-dimensional dynamic scapulohumeral rhythm was computed bilaterally. SPM ANOVAs were used for statistical analysis.

Findings

Twenty-two participants per group were included. The scapulohumeral rhythm of the two groups increased from 1.88 [mean] ± 0.79 [standard deviation] to 2.83 ± 1.52 during the ascending phase, while a decrease followed by a slight increase in the scapulohumeral rhythm were observed during the descending phase. The scapulohumeral rhythm did not significantly differ between the operated and non-operated sides or before and after surgery. When pooling the sides for each group, no significant differences were observed between the groups.

Interpretation

The scapulohumeral rhythm in patients who underwent the Latarjet procedure is not modified three months after surgery and is similar to the scapulohumeral rhythm of asymptomatic individuals. These findings suggest that in addition to restoring glenohumeral stability, the open Latarjet procedure preserves shoulder joint coordination three months postoperatively.

开放式 Latarjet 手术术后三个月不影响肩胛肱骨节律

背景虽然肩胛肱骨节律被认为是肩关节残疾的一个敏感指标，但目前尚未对开放式Latarjet术进行盂肱前稳定后的肩胛肱骨节律进行研究。本研究旨在评估与无症状者相比，接受开放式 Latarjet 手术的患者在接受盂肱关节稳定术后对肩胛骨节律的短期影响。使用电磁装置记录手术前和手术后三个月手臂在肩胛平面动态抬高和降低时肩胛胸和盂肱关节的运动学特性。然后，计算双侧肩胛骨和肱骨的三维动态节律。统计分析采用 SPM 方差分析。在上升阶段，两组的肩胛肱骨节律从 1.88[平均值] ± 0.79[标准差]上升到 2.83 ± 1.52，而在下降阶段，肩胛肱骨节律先下降后略有上升。手术侧和非手术侧以及手术前后的肩胛肱骨节律无明显差异。解释接受拉塔杰特手术的患者的肩胛肱骨节律在术后三个月没有改变，与无症状者的肩胛肱骨节律相似。这些研究结果表明，开放式Latarjet手术除了能恢复盂肱关节的稳定性外，还能在术后三个月保持肩关节的协调性。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
