Five-Year Results of a New Total Replacement Prosthesis for the Finger Metacarpo-phalangeal JointsFrom the Hand and Upper Limb Unit, Robert Jones and Agnes Hunt Orthopaedic and District Hospital Oswestry, Shropshire, UK and University Hospitals of Leicester, Groby Road, Leicester, LE3 9QP, UK Correspondence: Mr David Harris, Hand and Upper Limb Unit, Robert Jones and Agnes Hunt Orthopaedic and District Hospital NHS Trust, Oswestry, Shropshire SY10 7AG, UK.

An unconstrained surface metacarpophalangeal joint replacement was developed with metal metacarpal and polyethylene phalangeal components, fixed by uncemented finned polyethylene plugs which allowed some metacarpal component motion. Clinical and radiological results in 13 joints in eight patients are presented after 5 years. One infection required revision at 3 months. There were no further complications. At final review there were no implant failures. Two of 13 joints showed lucency around the phalangeal component and one showed 2 mm subsidence of the metacarpal component. No other adverse radiological features were observed. Seven patients had no pain and one had minor discomfort. Joint movement had improved from an arc of 27° to 60° and disability, assessed using the P.E.M. questionnaire, had improved from 77% to 9%.
