• To review the fundamental principles of using first dorsal metacarpal artery flaps.
• To provide an overview of reconstructive options for thumb soft tissue injuries.
• To highlight the versatility of these flaps in hand surgery.

Main Methods:

• Review of surgical techniques for first dorsal metacarpal artery flaps.
• Discussion of flap variations: racquet, island, and bilobed.
• Analysis of their application in reconstructive hand surgery.

Main Results:

• First dorsal metacarpal artery flaps offer a versatile reconstructive option.
• Different flap designs allow tailored solutions for thumb injuries.
• These flaps are a valuable tool in the microsurgical armamentarium.

Conclusions:

• First dorsal metacarpal artery flaps are effective for thumb soft tissue reconstruction.
• Understanding flap variations is crucial for successful surgical outcomes.
• Microsurgical flap techniques are essential for restoring hand function.
