Area of Science:

  • Orthopedics
  • Hand Surgery
  • Congenital Malformations

Background:

  • Thumb duplication (radial polydactyly) is a congenital alteration of hand plate formation.
  • It's classified under the radio-ulnar axis developmental abnormalities.
  • This condition can occur in isolation or as part of a broader syndrome.

Purpose of the Study:

  • To provide a comprehensive analysis of radial polydactyly.
  • To review genetic factors, classifications, and surgical techniques.
  • To evaluate functional results and current/future scientific evidence.

Main Methods:

  • Literature review of radial polydactyly.
  • Analysis of genetic underpinnings and classifications (e.g., Wassel).
  • Evaluation of surgical techniques and outcome assessment tools (Tada score, JSSH system).

Main Results:

  • The Wassel classification is standard but has limitations with immature epiphyses.
  • Surgical goals include thumb alignment, stability, and aesthetics.
  • Validated scales like Tada and JSSH assess functional outcomes and complications.

Conclusions:

  • Radial polydactyly requires careful classification and surgical planning.
  • While isolated defects are common, syndromic associations exist.
  • Further research is needed for evidence-based treatment guidelines.
