Reverse dorsal digital and intercommissural flaps used for digital reconstruction.

Reverse dorsal digital and intercommissural flaps offer a simple and versatile option for skin cover of distal finger defects, especially when other local flaps are not available. Twenty-one reverse dorsal digital flaps were used, on an outpatient basis, to cover dorsal soft tissue defects over or beyond the PIP joint. All the flaps were transposed as reverse island flaps. The average size of the defects was 2.5 cm(2) and they were all used to cover exposed tendon, bone, joint or a combination. Twenty flaps survived completely and did not present any feature of circulatory difficulty. Marginal necrosis of one flap was noticed, while two patients complained of swollen finger 6 months later. No morbidity was reported and the patients maintained good range of motion. Various other types of flaps that have been used to reconstruct distal digital skin defects are reviewed and compared with the reverse dorsal digital and metacarpal flaps.
