    Area of Science:

    • Orthopedic Surgery
    • Hand Surgery
    • Biomaterials Science

    Background:

    • Carpometacarpal (CMC) joint derangement causes significant hand pain and functional impairment.
    • Trapezium replacement arthroplasty is a surgical option for CMC joint arthritis.
    • Swanson silicone prostheses are commonly used in these procedures.

    Purpose of the Study:

    • To evaluate the long-term outcomes of trapezium replacement arthroplasty using Swanson silicone prostheses for CMC joint derangement.
    • To assess pain levels, joint mobility, strength, and patient satisfaction post-surgery.
    • To identify the incidence of radiographic complications.

    Main Methods:

    • A retrospective review of 31 patients (34 joints) who underwent trapezium replacement arthroplasty with Swanson silicone prostheses.

  • Follow-up duration ranged from 0.5 to 12 years.
  • Assessment included subjective pain evaluation, measurement of mobility and strength, and radiographic examination.

    • Main Results:

    • Twenty-five hands were pain-free at follow-up, with nine experiencing pain only on exertion.
    • Generally good restoration of mobility and strength was observed.
    • Radiographic findings included 12 prosthesis fractures, three dislocations, and five cases of incongruity.

    Conclusions:

    • Trapezium replacement arthroplasty with Swanson silicone prostheses provides satisfactory long-term pain relief and functional recovery for CMC joint derangement.
    • Despite a notable rate of radiographic complications, overall patient satisfaction remains high.
    • The study highlights the effectiveness of this surgical intervention in improving quality of life for patients with CMC joint pain.
