Silicone implant arthroplasty is effective for hand and wrist arthritis. Despite concerns about silicone synovitis, this study found a low symptomatic complication rate, supporting its continued use.

Area of Science:

  • Orthopedic Surgery
  • Hand and Wrist Surgery
  • Biomaterials in Medicine

Background:

  • Silicone implant arthroplasty is a common treatment for symptomatic hand and wrist arthritis.
  • Concerns regarding silicone synovitis have led to a decrease in implant usage.
  • The actual incidence and impact of silicone synovitis remain unclear.

Purpose of the Study:

  • To evaluate the incidence and outcomes of silicone implant arthroplasty in the hand and wrist.
  • To assess the development of symptomatic silicone synovitis after surgery.
  • To determine the long-term efficacy and safety of silicone implants.

Main Methods:

  • A retrospective survey of patients who underwent silicone implant arthroplasty between 1975 and 1990.
  • Exclusion of patients with rheumatoid arthritis and those undergoing MP or IP joint arthroplasty.

  • Personal review of 229 implants with a mean follow-up of 3.8 years.

    • Main Results:

    • 40% of reviewed implants showed significant radiological changes.
    • Only 4.8% of patients (11 out of 229) developed symptomatic silicone synovitis requiring treatment.
    • Revision surgery for symptomatic cases yielded entirely satisfactory results.

    Conclusions:

    • Silicone implant arthroplasty remains a viable and effective treatment for painful joint disease in the hand and wrist.
    • The incidence of symptomatic silicone synovitis is low, and complications are manageable.
    • The benefits of silicone implant arthroplasty outweigh the risks for selected patients.
