It might be challenging to identify an acceptable soft-tissue grafting material to seal a cut on the dorsum of a finger. The absence of locally accessible tissue makes it difficult to repair after dorsal tissue loss and subsequent tendon or joint exposure. Since local flaps, such as transposition and advancement flaps with random vascularity, are only able to move a small quantity of tissue from the surrounding area, their usage may be restricted. The dorsal metacarpal artery perforator flap (DMCA) is a vascular island flap that originates from the dorsum of the hand and may be used in a variety of ways to repair soft-tissue abnormalities in the fingers. Defects on the index finger, middle finger, and little finger are commonly repaired with the DMCA perforator flap. When other flap alternatives are restricted, such as with dorsal finger deformities, the dorsal metacarpal artery (DMCA) flap is a useful tool in the reconstructive hand surgeon's arsenal. The flap is straightforward to harvest with minimum donor site morbidity and complies with most reconstructive concepts, such as "to replace like with like." The first dorsal metacarpal artery (FDMA) flap, in particular, is commonly utilized to repair damage to the thumb. |
