A number of studies suggest a relationship between generalized joint laxity (GJL) and increased risk of some musculoskeletal injuries. However, there are conflicting data on the association between GJL and traumatic recurrent shoulder instability (RSI).
QUESTIONS/PURPOSES: We therefore asked whether the incidence of GJL in patients with RSI was greater than that in a control group.
We preoperatively determined GJL with a Beighton score in 100 male patients arthroscopically treated for RSI. The mean age of the patients was 25 years. We identified a control group of 100 individuals, matched for age and gender, with no known history of instability of the shoulder, knees, or ankles and obtained the same score. Those patients with a Beighton score greater than six points were considered lax (representing GJL).
We identified no difference in the rate of GJL in the two groups: 13 of the 100 patients versus nine of the 100 control subjects.
Our data add to the literature suggesting GJL does not predispose to RSI.

多项研究表明，全身性关节松弛症（GJL）与某些肌肉骨骼损伤的风险增加之间存在关联。然而，关于 GJL 与创伤性复发性肩关节不稳定（RSI）之间的关联，数据存在矛盾。
问题/目的：因此，我们询问 RSI 患者的 GJL 发生率是否高于对照组。
我们对 100 名接受 RSI 关节镜治疗的男性患者进行了术前 Beighton 评分，以确定 GJL。患者的平均年龄为 25 岁。我们确定了 100 名年龄和性别匹配、无已知肩、膝或踝关节不稳定病史的对照组，并获得了相同的评分。Beighton 评分大于 6 分的患者被认为是松弛的（代表 GJL）。
两组 GJL 的发生率无差异：100 名患者中有 13 名，100 名对照组中有 9 名。
我们的数据增加了文献中 GJL 不会导致 RSI 的证据。
