Introduction Shoulder instability injuries are common in sports involving collisions and overhead movements. Arthroscopic Bankart repair and the open Latarjet are two commonly used surgical stabilisation procedures. There is a lack of knowledge surrounding movement strategies, joint loading and muscle strength after each of these procedures. This study will compare: (1) shoulder joint neuromechanics during activities of daily living and an overhead sporting task; (2) shoulder range of motion; (3) shoulder strength; and (4) self-reported shoulder function and health status, between individuals who have undergone an arthroscopic Bankart repair versus open Latarjet. Methods and analysis This is a prospective cohort, single-centre, non-randomised parallel arm study of surgical interventions for athletic shoulder instability injuries. Thirty participants will be recruited. Of these, 20 will have experienced one or more traumatic shoulder instability injuries requiring surgical stabilisation—and will undergo an arthroscopic Bankart repair or open Latarjet procedure. The remaining 10 participants will have no history of shoulder instability injury and act as controls. Participants will undergo baseline testing and be followed up at 3, 6 and 12 months. A two-way (group×time) analysis of variance with repeated measures on one factor (ie, time) will compare each outcome measure between groups across time points. Ethics and dissemination This study was approved by the Barwon Health and Deakin University Human Research Ethics Committees. Outcomes will be disseminated through publications in peer-reviewed journals and presentations at relevant scientific conferences. Trial registration number Australian and New Zealand Clinical Trials Registry (ACTRN12620000016932).

评估关节镜 Bankart 修复和开放式 Latarjet 肩部稳定程序对肩关节神经力学和功能的影响：单中心、平行臂试验方案

简介 肩部不稳定损伤在涉及碰撞和头顶运动的运动中很常见。关节镜 Bankart 修复和开放式 Latarjet 是两种常用的手术稳定程序。在这些程序中的每一个之后，缺乏关于运动策略、关节负荷和肌肉力量的知识。本研究将比较： (1) 日常生活活动和头顶运动任务期间的肩关节神经力学；(2)肩关节活动度；(3) 肩部力量；(4) 接受关节镜 Bankart 修复与开放式 Latarjet 的个体之间自我报告的肩部功能和健康状况。方法和分析 这是一项前瞻性队列、单中心、非随机平行臂研究，针对运动性肩部不稳损伤的外科干预进行了研究。将招募三十名参与者。其中，20 人将经历过一次或多次创伤性肩部不稳定损伤，需要手术稳定——并将接受关节镜 Bankart 修复或开放式 Latarjet 手术。其余 10 名参与者将没有肩部不稳定损伤的历史并充当对照。参与者将接受基线测试，并在 3、6 和 12 个月时进行随访。对一个因素（即时间）进行重复测量的双向（组×时间）方差分析将跨时间点比较组之间的每个结果测量。伦理和传播 本研究得到了 Barwon Health 和 Deakin 大学人类研究伦理委员会的批准。成果将通过同行评审期刊上的出版物和相关科学会议上的演讲进行传播。
