Identifying the entry point for transcapitate intramedullary implant insertion into the third metacarpal in rheumatoid and osteoarthritis.

This anatomical study identifies the optimum entry point for intramedullary implant insertion into the capitate during total wrist arthroplasty. An entry point more radial and distal from the centre of the capitate head is suggested to avoid fractures and perforations in rheumatoid hands.
