Digital artery perforator flap transfer for volar soft tissue defect due to dissociation from joint contracture in camptodactyly

Abstract

Summary: Camptodactyly is a condition defined by persistent flexion contracture of the proximal interphalangeal joints of the hand. Surgical treatment requires flaps for the dissection of the skin and the resulting soft tissue defect, soft tissue release, and sometimes reconstruction of the extension mechanism. Z-plasty and transposition flap have been reported as methods used in soft tissue defects. In this case, covering the defects of the digits was necessary for keeping the wound clean; thus, we should select a surgical method that facilitates stable and reliable blood flow of the flap. The digital artery perforator flap is pedicled and its transfer does not require the dissection of neurovascular bundles; therefore, it can be used safety and relatively easily. We considered the digital artery perforator flap to be a useful technique in terms of securing stable and reliable blood flow and not twisting the skin. Thus, we performed a digital artery perforator flap transfer for a volar soft tissue defect due to dissociation from proximal interphalangeal joint contracture in camptodactyly.
