Abstract
The anatomic and clinical bases for the reliable and versatile boomerang flap in reconstruction of complex distal finger injuries are presented. This one-step procedure, utilizing the dorsolateral skin of the proximal phalanx of an adjacent digit as a reverse island flap, has proved valuable in the salvage of severely injured digits. The boomerang flap was applied in ten cases with distal phalanx injuries. Soft tissue defects in all patients were combined with bone, joint, or tendon exposure. The flaps were transferred as a neurovascular flap for sensory resurfacing of the major pulp loss. This flap preserves the proper palmar digital artery to the fingertip and provides an extended and innervated skin paddle to cover finger soft tissue defect as well as to improve flap sensibility in the distal pulp.
