Osseointegrated finger prosthesis: An alternative method for finger reconstruction.

Abstract

Three patients had traumatic amputation of the index and middle fingers at the base of the proximal phalanx. A 2-stage reconstruction procedure with osseointegrated titanium implants was performed in each patient to fix a finger prosthesis to the proximal phalanx. The first stage included implantation of the titanium fixture into the medullary canal of the proximal phalanx. After a 3-month rest period to allow the fixture to firmly osseointegrate with the proximal phalanx, a skin-penetrating abutment was placed on top of the fixture, to which the prosthesis was firmly attached. The follow-up period ranged from 16 to 24 months. There were minimal skin problems. Some tactile sensibility, better motor function, and good cosmetic results were achieved.
