Extended Application of WISH type S-form hip Brace for Patients with Bilateral Painful Hip Osteoarthritis

Abstract

Dynamic lateral instability of the femoral head develops in patients with osteoarthritis (OA) of the hip. Recently we have developed a hip brace, called the WISH-type hip brace, and showed successful response of the patients quantitatively. However, a negligible effect was observed in patients with bilateral involvement. Here, we extended the application of the WISH-type hip brace for two patients with bilateral OA joints. The resultant WISH-type hip brace with two S-form portions for bilateral thighs provided good recovery in hip function. Interestingly Timed Up & Go (TUG) test performed for one patient revealed a positive effect of the brace on the functional mobility. To the best of our knowledge, this is the first report elucidating the therapeutic effect of brace therapy with bilateral hip stabilization from hip functional and functional mobility points of view. Application of the present brace should be taken into account for patients with painful bilateral hip OA before easy application of invasive surgery such as total hip arthroplasty.
