One-stage reconstruction for amputated thumbs with melanoma

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Microsurgery

Background:

• Thumb amputation presents significant reconstructive challenges due to functional and aesthetic deficits.
• Traditional methods often yield suboptimal results, necessitating innovative surgical approaches.

Observation:

• Two patients with amputated thumbs underwent single-stage reconstruction using a modified wrap-around flap.
• The procedure utilized an onychocutaneous flap from the big toe for partial defects and a combined dorsalis pedis and wrap-around flap for total thumb reconstruction.

Findings:

• The modified wrap-around flap procedure demonstrated suitability for both partial and total thumb defects.
• This technique effectively addressed varying thumb lengths and volumes, including nail bed reconstruction.

Implications:

• This one-stage reconstructive approach offers a promising solution for thumb amputation, potentially improving functional and aesthetic outcomes.
• The described flap techniques provide valuable options for surgeons managing complex thumb defects.
