Abstract
AbstractOur 4‐year clinical experience with reconstruction of worn metacarpo‐phalangeal and proximal interphalangeal joints with silicone‐Dacron prostheses in 121 patients is presented.Emphasis is on preoperative assessment and proper selection of patients.Three hundred sixty‐nine metacarpophalangeal joint prostheses and 27 proximal interphalangeal joint prostheses have been inserted. Most of the patients had rheumatoid arthritis; several had degenerative arthroses, and a few had traumatic arthrosis.Particular attention is directed to minor modification of surgical techniques and emphasis is on postoperative management. Suggestions for implant redesigning and modification are made.The silicone‐Dacron arthroplasties have been successful in decreasing pain, improving stability, increasing hand function, and in providing an adequate range of motion.Complications have included five infections, two recognized fractured prostheses, and two instances of early dislocation of a prosthesis. The patients have consistently been relieved of pain: on the basis of this short‐term experience, we believe that the implant principle in the hand is successful, but improvements in design and material are needed.
