Three- to Six-Year Results of Metacarpophalangeal Joints Arthroplasty in Psoriatic Arthritis

Abstract

Patients with psoriatic arthritis often need the replacement of the hand joints owing to the high prevalence of hand joints involvement and their often severe destruction and/or function loss. The long-term results of silicone arthroplasty of metacarpophalangeal joints in psoriatic patients are almost unreported in the scientific literature. We analyzed 3- to 6-year results of 14 metacarpophalangeal joint replacements with silicone implants that we performed in nine psoriatic patients. The metacarpophalangeal joints arthroplasty in all the patients led to the significant short-term and long-term increase of range of motions and decrease of pain. However, two complications occurred. The choice of the implant, the possibility, causes, and significance of the complications are justified. Metacarpophalangeal joints silicone arthroplasty in psoriatic arthritis during skin manifestations remission period is an effective and relatively safe method of finger joints contractures and deformities treatment.
