First dorsal metacarpal artery flap in hand reconstruction. II. Clinical application

Area of Science:

• Hand surgery
• Plastic surgery
• Reconstructive surgery

Background:

• Soft tissue defects in the hand pose significant reconstructive challenges.
• The first dorsal metacarpal artery (FDMA) flap is a potential option for hand defect coverage.

Purpose of the Study:

• To evaluate the efficacy of the first dorsal metacarpal artery flap for soft tissue hand defect coverage.

Main Methods:

• The FDMA flap was utilized in 23 patients.
• The flap was employed as either a fasciocutaneous or fascial flap.
• In some cases, vascularized periosteum or tendon was raised with the flap.

Main Results:

• The FDMA flap provided successful coverage for soft tissue hand defects in the studied cohort.
• The flap demonstrated versatility in its application as fasciocutaneous or fascial.
• The ability to include adjacent tissues expanded its reconstructive utility.

Conclusions:

• The first dorsal metacarpal artery flap is a reliable and versatile option for reconstructing soft tissue hand defects.
• Its adaptability allows for various flap designs, including fasciocutaneous, fascial, and inclusion of periosteum or tendon.
• This flap represents a valuable tool in the armamentarium of hand and reconstructive surgeons.
