Silastic implant arthroplasty for post-traumatic stiffness of the finger joints.

In the years 1981 to 1987, 50 patients had 59 replacements of the finger joints. Of these, 41 patients with 49 joint operations were reviewed, with follow-up ranging from two to eight years (average 32 months). About 80% of these patients were satisfied that silastic implant arthroplasty had relieved their pain and stiffness and improved function of the finger and hand. They were satisfied that this procedure was preferable to amputation or fusion. Success or failure was assessed not only on the range of movement of the joint being replaced, but on relief of pain, correction of deformity, stability and overall finger function. The seven patients regarded as failures are analysed in detail.
