Correction of thumb deformities after burn: versatility of first dorsal metacarpal artery flap.
In the management of a debilitated burned hand due to contractures, thumb reconstruction constitutes the most crucial part for a beneficial functional outcome. Among the limited local flap alternatives for the thumb, the first dorsal metacarpal artery flap, harvested from the dorsal aspect of the index finger can provide elastic, durable and sensate coverage for soft tissue defects after contracture release. In a 3-year period, neurovascular island first dorsal metacarpal artery flap was used in 14 patients suffering thumb deformities. The time elapsed after the underlying injury until reconstruction ranged from 5 months to 17 years. Follow-up revealed that all deformities were successfully treated with satisfactory functional recovery and cosmetic results. Donor site morbidity was minimal with an acceptable scar on the dorsum of the index finger and adequate tendon gliding without producing extension deficit. Our experience with management of deformities involving the thumb and/or adjacent thenar area revealed that the first dorsal metacarpal artery flap is a reliable local neurovascular island flap option, offering acceptable functional and cosmetic outcomes in respect to sensation, elasticity, durability and skin-match.
