Radial polydactyly: an outcome study

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.
