Posterior shoulder instability in overhead athletes presents a unique and difficult challenge. Often, this group has an inherent capsular laxity and/or humeral retroversion to accommodate the range of motion necessary to throw. This adaptation makes the diagnosis of posterior capsulolabral pathology challenging, as the examiner must differentiate between adaptive capsular laxity and pathologic instability. Further complicating matters, the intraoperative surgeon must find the delicate balance of achieving stability while still allowing the necessary range of motion.
过头运动运动员的肩关节后向不稳是一个独特且棘手的挑战。通常，这类人群存在先天性关节囊松弛和/或肱骨后倾，以适应投掷所需的活动范围。这种适应性变化使得后关节囊盂唇病变的诊断颇具挑战性，因为检查者必须区分适应性关节囊松弛和病理性不稳。更复杂的是，术中外科医生必须在实现稳定的同时，还要找到保持必要活动范围的微妙平衡。
