Three- to six-year results of metacarpophalangeal joints arthroplasty in psoriatic arthritis.

Background: 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.

Materials And Methods: We analyzed 3- to 6-year results of 14 metacarpophalangeal joint replacements with silicone implants that we performed in nine psoriatic patients.

Results: 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.

Conclusions: 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.
