Chronic Ankle Instability: Results with Brostrom-Evans Procedure

Albiñana Cuningham Juan, Macklin Vadell Alberto and Peratta Marcela

Ankle inversion injuries account for 40% of all sport injuries and up to 20-24% of these will have residual pain, instability, or a combination of both. There are two types of chronic ankle instability: functional and mechanical. In this study, we will retrospectively analyze the Brostrom-Evans technique used to treat the mechanical chronic instabilities. We have reviewed ten procedures in nine recreational athletes, 6 male and 4 female, one of which was bilateral. In two cases, a calcaneal osteotomy was associated to correct the hindfoot varus. The Brostrom-Evans technique solves the chronic instability problem by sacrificing the normal inversion movement of the ankle. We would recommend modifying the hindfoot varus and then performing a Brostrom-Evans plasty in those cases in which a calcaneus varus is associated to a chronic instability.
