Wrist Hemiarthroplasty for Complex Intraarticular Distal Radius Fracture in a Patient with Manifest Osteoporosis.

Distal radius fracture (DRF) is one of the most common fractures of the elderly. The higher the degree of joint surface destruction, and the more adverse factors are involved, the more challenging proper treatment becomes. In this regard, osteoporosis as underlying systemic disease, chondropathy or degeneration of adjacent wrist bones as well as incompliance significantly impair the success of the chosen primary therapy. Wrist hemiarthroplasty has already been reported as primary or secondary procedure for DRFs. In this case report, we present a patient with a severely comminuted DRF including posttraumatic degeneration of the lunate as well as manifest osteoporosis. Wrist hemiarthroplasty using the ReMotion radius component in combination with proximal row carpectomy was performed as secondary surgery. This procedure proved to be a viable treatment option in terms of achieving low pain levels, high range of motion values and stable osteointegration over a course of 6.5 follow-up years.
