Perichondrial arthroplasty in the hand: a case report.
A two-stage arthroplasty technique was used to treat an isolated fibrous ankylosis that developed in the index metacarpophalangeal joint of a 14-year-old boy after a rattlesnake bite. The first stage consisted of a minimal joint resection combined with rib perichondrial grafts to resurface the joint. The second stage, performed 5 months later, consisted of a capsulotomy and removal of a silicone membrane left within the joint to separate the grafts. Biopsy of the joint surfaces revealed the presence of hyaline-like cartilage. Nearly normal pain-free motion was restored. Follow-up now exceeds 30 months.
