Resurfacing Capitate Pyrocarbon Implant versus Proximal Row Carpectomy Alone: A Comparative Study to Evaluate the Role of Capitate Prosthetic Resurfacing in Advanced Carpal Collapse.

Background: The Resurfacing Capitate Pyrocarbon Implant associated with proximal row carpectomy has been used to treat symptomatic advanced carpal collapse, widening the indications of proximal row carpectomy to patients with capitate head arthritis. The authors retrospectively compared their case series of implant versus carpectomy alone, analyzing whether prosthetic implant outcomes could be similar to those of proximal row carpectomy even with a higher stage of osteoarthritis.

Methods: Fifty-seven patients who underwent surgery for wrist osteoarthritis (minimum follow-up, 2 years) were selected retrospectively.
