Radial polydactyly, or thumb duplication, has limited outcome data for the Bilhaut-Cloquet procedure. While surgical techniques improve appearance and stability, none restore normal joint motion, though patient satisfaction is high.

Area of Science:

  • Orthopedics
  • Congenital Hand Surgery
  • Pediatric Hand Surgery

Background:

  • Radial polydactyly is a common congenital hand difference, often presenting as thumb duplication.
  • Limited data exists on the long-term outcomes of surgical interventions, particularly the Bilhaut-Cloquet procedure.

Purpose of the Study:

  • To evaluate the clinical outcomes of various operative and nonoperative treatments for radial polydactyly.
  • To assess the effectiveness of the Bilhaut-Cloquet procedure compared to other methods.

Main Methods:

  • Retrospective chart review of 21 patients (26 thumbs) treated between 1979-1994.
  • Surgical groups included ablation alone, ablation with ligament reconstruction/shaving, and Bilhaut-Cloquet procedure.
  • Nonoperative management was used for Wassel type I classification.

Main Results:

  • Ablation alone had a high reoperation rate (5/6 thumbs required subsequent procedures).
  • Combined ablation with reconstruction improved alignment and stability but not interphalangeal joint motion.
  • The Bilhaut-Cloquet procedure enhanced cosmetic and functional appearance but did not restore normal joint motion.

Conclusions:

  • Ablation of the thumb without reconstruction is contraindicated due to high reoperation rates.
  • Current surgical techniques improve thumb appearance and stability but do not guarantee normal joint motion.
  • Despite functional limitations, all patients reported significant improvement and satisfaction compared to their preoperative condition.
