Triphalangeal Thumb Reduction Osteotomy Through a Versatile Spiral Approach.

Area of Science:

• Congenital Hand Surgery
• Pediatric Orthopedics

Background:

• Triphalangeal thumb (TPT) is a congenital anomaly resulting in thumb deformity, malalignment, and excessive length.
• Functional impairment and psychological distress are common in TPT patients due to abnormal thumb appearance and length.

Observation:

• Established surgical methods for TPT, such as extra phalanx removal or reduction osteotomy, often leave residual skin and soft tissue surplus.
• Classic circular incisions used in TPT surgery do not adequately address the soft tissue excess post-osteotomy.

Findings:

• A spiral incision approach for TPT reconstruction provides ample anatomic exposure.
• This technique allows for simultaneous reduction of both skeletal and soft tissue components, effectively managing skin and soft tissue surplus.

Implications:

• The spiral incision technique offers a comprehensive solution for TPT, improving both functional outcomes and aesthetic appearance.
• This approach may represent a significant advancement in surgical correction for triphalangeal thumb, enhancing patient satisfaction.
