Abstract
Metacarpophalangeal joint replacement is one of the most common surgery performed for rheumatoid hand deformities. The systemic and progressive nature of rheumatoid arthritis and other inflammatory arthritis make isolated assessment and treatment of metacarpophalangeal joint joints challenging.Extensive joint involvement and systemic nature of the illness has an impact in the prognosis of the illness. The long term outcome of the surgical procedure depends on how best the illness is controlled. Technical aspects of the surgery in patients with rheumatoid arthritis can be widely variable and can make implant arthroplasty challenging. We present a case report of an unusual presentation of a rare complication following metacarpophalangeal joint replacement performed 17 years ago.

On examination, a nodule was seen over the metacarpophalangeal joint of the index finger
We present a case report of an unusual presentation of a rare complication following metacarpophalangeal joint replacement performed 17 years ago
We found one case of index finger distal interphalangeal joint silicone arthroplasty, where the implant had eroded through the skin and was removed with satisfactory results [10]
Summary
MCP joint replacement in rheumatoid arthritis (RA) patients is one of the commonest surgeries performed for hand deformities and functional difficulties. Complications reported for a MCP joint replacement are namely implant fracture, periprosthetic cyst formation, subsidence, Silicone arthroplasty for MCP joint replacement, introduced by Swanson in 1962, has remained the most popular procedure [5]. Implants have moved toward semiconstrained or non-constrained designs and toward minimal bone resection that aims at preserving soft tissue supports to unload component stems and improve fixation while mimicking joint biomechanics. These implants are comparatively new in market and there long-term results are awaited
