Extensor indicis proprius opponensplasty is effective for hand deformities, with 87.5% of patients achieving excellent or good outcomes. This reconstructive surgery offers significant functional improvement for many individuals.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Reconstructive Surgery

Background:

  • Opponensplasty is a crucial procedure for restoring thumb function in various hand deformities.
  • The extensor indicis proprius (EIP) tendon transfer is a common technique for this surgery.
  • Evaluating the outcomes of EIP opponensplasty, especially with concurrent corrective procedures, is important for surgical decision-making.

Purpose of the Study:

  • To analyze the functional outcomes of extensor indicis proprius opponensplasty.
  • To assess the results of EIP opponensplasty when performed with simultaneous adjuvant surgeries for other hand deformities.

Main Methods:

  • Retrospective analysis of 39 patients (40 hands) who underwent EIP opponensplasty.
  • Data collection included patient demographics, surgical procedures, and follow-up assessments.

Related Experiment Videos

  • Mean follow-up duration was 33.8 months.

    • Main Results:

    • Overall, 87.5% of hands achieved excellent or good functional results.
    • Fair results were observed in 10% of hands, and poor results in 2.4%.
    • A significant proportion of patients (29 hands) had simultaneous corrective surgeries, indicating the procedure's versatility.

    Conclusions:

    • Extensor indicis proprius opponensplasty demonstrates high efficacy in improving thumb function.
    • The procedure yields favorable outcomes even when combined with other surgical interventions for hand deformities.
    • EIP opponensplasty is a reliable reconstructive option for patients requiring restoration of thumb opposition.
