Modified Broström Procedure for Chronic Ankle Instability With Generalized Joint Hypermobility.

Background:Chronic ankle instability with generalized joint hypermobility (GJH) is considered a contraindication for the modified Brostrom procedure. The most widely accepted definition of GJH is a Beighton score of ≥4 on a 9-point scale. However, it is not clear whether this criterion can be applied to determine the GJH that would lead to a poor outcome after a modified Brostrom procedure. Some of the previous studies that report unfavorable outcomes do not specify the tests or cutoff scores used to determine the GJH, and, in fact, some of the patients with GJH in these studies had good outcomes.Hypothesis:The modified Brostrom procedure results in satisfactory outcomes in patients who have chronic ankle instability with GJH if the contralateral uninjured ankle shows a normal varus talar tilt and anterior talar translation during stress tests.Study Design:Case series; Level of evidence, 4.Methods:Modified Brostrom procedure was performed in 32 patients with chronic ankle instability with GJH if the contr...
