PURPOSE: To describe the reconstruction of small defects on the dorsum of the hands using a first dorsal metacarpal artery-based fascial flap harvested through the borders of the defect.
METHODS: From January, 2015 to May, 2017, 29 patients (29 hands) with soft tissue defects on the dorsum of the hand were treated using a first dorsal metacarpal artery-based fascial flap. At final follow-up, we measured range of motion of the metacarpophalangeal joints and the first web span.
RESULTS: Average size of the defects was 2.7 × 2.5 cm. Average size of the flaps was 2.9 × 2.7 cm. Average length of the pedicle was 2.9 cm. All flaps survived. Range of motion of the second to fourth metacarpophalangeal joints reached 93% to 98% of the opposite hand. The span of the first web reached 98% of the opposite hand.
CONCLUSIONS: A first dorsal metacarpal artery-based fascial flap can be an alternative for reconstruction of small defects on the dorsum of the hands. Flap harvesting through the border of the defect avoided an additional scar at the donor site.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
