An On-Top-Plasty Reconstruction for Complicated Radial Polydactyly

Area of Science:

• Hand surgery
• Pediatric orthopedics
• Congenital anomalies

Background:

• Radial polydactyly presents with diverse clinical manifestations.
• Understanding subtle anatomical variations is crucial for surgical planning.
• Tailored surgical approaches can enhance patient outcomes.

Purpose of the Study:

• To describe a novel surgical reconstruction for radial polydactyly.
• To demonstrate the utility of spare-part surgery in complex hand anomalies.
• To improve both aesthetic and functional results in thumb reconstruction.

Main Methods:

• Case presentation of a patient with radial polydactyly, featuring an accessory thumb and a hypoplastic primary thumb.
• Surgical technique involved an on-top-plasty reconstruction using the accessory digit.
• The diminutive distal phalanx of the primary thumb was replaced with elements from the accessory digit.

Main Results:

• Successful reconstruction of the primary thumb using the spare-part on-top-plasty technique.
• The reconstructed digit exhibited improved aesthetics and functionality.
• Avoidance of simple excision of the accessory digit preserved valuable surgical tissue.

Conclusions:

• Spare-part surgery offers a viable and effective alternative for radial polydactyly reconstruction.
• This novel approach addresses complex thumb hypoplasia by utilizing accessory digits.
• The described technique can lead to superior functional and aesthetic outcomes in challenging cases.
