Reconstruction of radial polydactyly.

Area of Science:

• Orthopedics
• Hand Surgery
• Congenital Malformations

Background:

• Radial polydactyly presents a spectrum of thumb duplication.
• The Wassel classification system categorizes these differences.
• Surgical reconstruction is tailored to individual thumb characteristics.

Purpose of the Study:

• To outline the principles of radial polydactyly reconstruction.
• To describe the management of Wassel type 4 radial polydactyly.
• To highlight the complexity of other radial polydactyly types.

Main Methods:

• Classification of radial polydactyly using the Wassel system.
• Assessment of thumb size and quality for surgical planning.
• Surgical techniques including thumb excision, centralization, and ligament reconstruction.

Main Results:

• The ulnar thumb is typically larger and preserved.
• The smaller radial thumb is commonly excised.
• Wassel type 4 involves excision, centralization, alignment, and radial collateral ligament reconstruction.

Conclusions:

• Reconstruction strategies for radial polydactyly are diverse.
• Wassel type 4 has a defined surgical approach.
• More complex types necessitate intricate reconstructive procedures.
