Periprosthetic radius fracture after total wrist arthroplasty: A case report

Total wrist arthroplasty (TWA) is indicated in select low demand patients with pan-carpal arthritis to decrease pain and preserve motion. Complications of TWA are well described including aseptic loosening, superficial and deep infection, wound issues, component dislocation, stiffness, and both intraoperative and post-operative fracture. With 4th generation implant designs, the incidence of many of these complications have decreased, but these complications remain challenging to address. In particular, sparse literature is available for the treatment of periprosthetic radius fractures after TWA. This report describes the management of an open, periprosthetic distal third radius fracture 18 months after index TWA in a medically complex 53-year-old female with lag screw fixation and a dorsal wrist spanning plate (DSP).
