Dorsocommissural flap.

We present a case of dorsoradial skin loss over the middle phalanx of the middle finger with section of the central slip of the extensor tendon and loss of one lateral band following mechanical injury. Successful primary reconstruction of the central slip was performed by retrograde flap from the central slip of the extensor tendon tied with barb-wire over a padded button, splinted for 2 weeks with a K-wire, and skin cover with a dorsocommissural flap based on the second web space. Other reconstructive options are discussed.
