Hand involvement in psoriatic arthritis.
From a population of 105 patients with confirmed psoriatic arthritis, 25 patients required hand surgery. These 25 surgical patients were evaluated retrospectively both clinically and radiographically. The patterns of hand and wrist involvement as well as the results of surgery differed from those typically seen in rheumatoid disease. Spontaneous fusion of the wrist in a functional position, severe proximal interphalangeal involvement often with marked flexion contractures, severe erosion of the distal interphalangeal joint with spontaneous fusions, and generalized stiffness characterize these hands. Minimal improvement in motion and a significantly increased incidence of infection following arthroplasty were noted.
