The use of two cross finger flaps from one digit has not been previously reported and the technique raises concerns regarding donor finger morbidity. In this paper, the authors report on a case series of double cross fingers flaps harvested from the middle finger to reconstruct large defects in the adjacent index or ring finger; with an emphasis on documenting morbidity in the donor middle finger.
A total of four cases of double cross finger flaps were retrospectively reviewed. Demographic data, surgery, and postoperative complications were documented. Donor middle finger morbidity (stiffness, painful neuromas, skin graft instability, cold intolerance and cosmetic concerns) were also documented.
All patients were young male industrial workers. Two patients underwent reconstruction with de-epithelialized cross finger flaps and the other two patients had classic cross finger flaps. No postoperative complications were noted. Mild stiffness at the distal interphalangeal joints were noted in all patients. There were no painful neuromas and one donor site had occasional blistering at the site of the skin graft. Mild cold intolerance was seen in the two patients with electric burns. Hyperpigmentation of the skin grafts was noted in all patients.
Our paper introduces to the literature the technique of utilizing two cross finger flaps from the middle finger to reconstruct large dorsal or volar defects of the adjacent index or ring finger. The study shows that the technique is feasible and is easily executed. The results document an acceptable donor finger morbidity.
