A dynamic myocutaneous flap for hand reconstruction

Area of Science:

• Reconstructive surgery
• Plastic surgery
• Hand surgery

Background:

• Neurovascular pedicle transfer and myocutaneous flaps are established reconstructive techniques.
• The dynamic myocutaneous flap represents an advancement, combining muscle and skin transfer.
• This technique utilizes the neurovascular bundle for flap viability.

Observation:

• Injection studies confirmed the viability of transferring the abductor digiti quinti muscle and overlying hypothenar skin.
• The neurovascular bundle supports the transferred tissue.
• The flap was successfully used in a clinical case.

Findings:

• A dynamic myocutaneous flap successfully reconstructed skin cover and functional opposition.
• The flap was used following resection of a thumb arteriovenous malformation.
• This technique is a viable option for complex hand reconstructions.

Implications:

• The dynamic myocutaneous flap offers a new option for reconstructing defects in the hand.
• Potential applications include defects from electrical burns, avulsions, or tumor resections.
• This technique expands the versatility of myocutaneous flaps in reconstructive surgery.
