Transverse snuffbox perforator flap for a first-web contracture: an anatomical study and case report

Area of Science:

• Hand surgery
• Plastic surgery
• Anatomy

Background:

• Thumb hypoplasia and first-web contracture present significant reconstructive challenges.
• Limited reconstructive options exist for complex first-web contractures.

Observation:

• A transverse elliptical cutaneous flap was designed on the dorsal wrist.
• The flap's vascular supply was based on radial artery cutaneous perforators in the anatomical snuffbox.

Findings:

• The described flap is a reliable and viable option for reconstruction.
• Successful application of the flap in a pediatric case with thumb hypoplasia and first-web contracture was demonstrated.

Implications:

• This flap offers a novel solution for treating thumb hypoplasia and first-web contractures.
• The technique expands the armamentarium of reconstructive surgeons for upper extremity deformities.
