Resurfacing arthroplasty versus silicone arthroplasty for proximal interphalangeal joint osteoarthritis.

Purpose: To compare the outcomes of silicone proximal interphalangeal joint (PIPJ) arthroplasties to pyrolytic carbon implants in patients with osteoarthritis.

Methods: This study is a retrospective review of 41 arthroplasties in 22 patients with severe PIPJ osteoarthritis performed by a single surgeon. There were 13 patients and 22 joints in the silicone group with an average follow-up of 45 months.

Pyrolytic carbon proximal interphalangeal joint resurfacing arthroplasty.

Purpose: To evaluate the clinical results of a pyrolytic carbon resurfacing proximal interphalangeal joint (PIPJ) arthroplasty in patients with osteoarthritis.

Methods: A retrospective review of 18 PIPJ arthroplasties in 8 women with severe osteoarthritis performed by a single surgeon was completed with an average follow-up period of 13 months. Clinical assessment included range of motion (ROM), stability, and deformity.

Tendon avulsion injuries of the distal phalanx.

Unlabelled: Mallet injuries are the result of incompetence of the terminal tendon. Most acute mallet fingers can be treated by continuous splinting of the distal interphalangeal (DIP) joint in extension for 5-6 weeks. Fracture dislocations require open reduction and internal fixation.
