Abstract

BACKGROUND:

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.

METHODS:

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).

RESULTS:

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.

CONCLUSION:

Our data add to the literature suggesting GJL does not predispose to RSI.

LEVEL OF EVIDENCE:

Level II, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.
