title: Dorsal transposition flap for reconstruction of lateral or medial oblique amputations of the thumb with exposure of bone.
abstract: A dorsal transposition flap for the treatment of medial or lateral oblique amputations of the thumb is indicated when the amputation extends proximal or up to the eponychial fold with loss of the paronychial fold and exposure of bone. The procedure, exemplified in three typical cases, obviates the need for cross-digit flaps and avoids the risk of digital stiffness.
