Abstract：

Objective To explore the effect of using proper digital artery lateral cutaneous branch-chain flap with dorsal digital nerves or dorsal branch of proper digital nerye for repairing of fingertip defect.Methods From December 2008 to November 2009, 24 cases (26 digits) of fingertip defect were treated with proper digital artery lateral cutaneous branch-chain flap.The flap was designed on the lateral side of the proximal phalanx of the injured finger with its long axis running on the lateral midline of the finger.The vascular pedicle was 0.8 to 1.0 cm wide.The pivot point was at the distal 1/3 of the middle phalanx upon which the flap was reversed to repair the defect of the fingertip.The dorsal digital nerve or dorsal branch of proper digital nerve was included in the flap and coapted with the nerve in the wound to reconstruct sensation of the injured finger.Results All 26 flaps survived.Postoperative follow-up period was 6 to 8 months.All these flaps recovered with satisfying and quality, excellent sensation with 4 to 8 mm two-point discrimination.ROM of the interphalangeal joint of the injured finger was good.Conclusion Proper digital artery lateral cutaneous branchchain flap transfer with nerve coaptation is an ideal method for repairing fingertip defect.The surgery is simple.Reliable blood supply can be achieved without sacrificing the proper digital artery.Coaptation of the nerve restores sensation at the fingertip.There is minor donor site damage and very few complications.

Direct and reversed dorsal digital island flaps: A review of 65 cases

BackgroundReconstruction of soft tissue defects in fingers continues to be a challenging problem. The purpose of this study is to report the reconstruction of small-to-moderate defects of fingers with dorsal digital island flap (DDIF) and to evaluate the efficacy of use of the flap.MethodsOver last six years, a retrospective study was conducted with 65 patients who had soft tissue defects of fingers treated with the DDIF. Sixty-nine soft-tissue defects were found in 69 fingers in 65 patients. Based on the flow direction of blood supply, the patients were divided into two groups: the direct (n = 35) and reversed (n = 30) DDIF groups. In addition, based on the different donor sites, the direct DDIF group was divided into two subgroups: the proximal phalangeal direct DDIF subgroup (n = 16) and the extended pedicle direct DDIF subgroup (n = 19). The main outcomes were static 2-point discrimination and Semmes–Weinstein monofilament scores of flap and joint motion.ResultsAt the final follow-up, the mean static two-point discrimination of the flaps was 9.7 mm (range, 8 to 12 mm) in the proximal phalangeal direct DDIF subgroup and 8.3 mm (range, 7 to 11 mm) in the extended pedicle direct DDIF subgroup, with a significant difference (p = 0.005). In the direct DDIF group, there was no significant difference in total active motion between the donor fingers and the opposite sides. In the reversed DDIF group, the mean total active motion of the donor fingers was 170° and the data of the opposite sides was 181°, with a significant difference (p = 0.024). Maximum amplitude losses of 15° were seen in 12% of patients in the distal interphalangeal joint.ConclusionsThe DDIF is reliable and technically easy for reconstructing small-to-moderate defects of fingers. The extended pedicle direct DDIF may be an optional solution when sensory reconstruction is needed.

Abstract：

Objective To report operative procedures and clinical results of repairing finger soft tissue defects with a modified reversed island flap pedicled on a perforating branch of the dorsal metacarpal artery. Methods From January 2005 to March 2008,we repaired 38 finger soft tissue defects in 31 patients (26 men and 5 women) with a modified reversed island flap pedicled on a distal perforating branch of the dorsal metacarpal artery and anastomosis of the cutaneous nerve.Their ages ranged from 14 to 66 years,with a mean of 29.6 years.Altogether 11 index,18 middle,6 ring and 3 little fingers were injured.Nine patients were complicated with rupture of tendons,3 with extenso-tendon defects and 5 with middle phalanx fractures.The defect areas ranged from 1.0 cm × 0.8 cm to 3.2 cm× 2.5 cm.The flap areas ranged from 1.2 cm× 1.0 cm to 3.5 cm× 2.8 cm.The flap did not carry a full length of the dorsal metacarpal artery but only the distal perforating branch of the artery.The rotating point of the flap pedicle was altered from the dorsal to the palmar side to extend the vessel pedicle.The donor sites were closed by suture or skin graft. Results Twenty-eight patients (35 fingers) were followed up for 3 to 25 months (mean,15.3 months) .All flaps survived with satisfactory appearance,sensation and function.All flaps and donor sites obtained primary healing.The two-point discrimination was 6 to 9 mm (mean,7.7 mm).According to Total Active Movement (TAM) evaluation system,the results were excellent in 20,good in 13 and fair in 2 fingers,with a good to excellent rate of 94.3％. Conclusion The modified reversed island flap pedicled on a distal perforating branch of the dorsal metacarpal artery and anastomosis of the cutaneous nerve is an easy,safe and effective treatment for finger soft tissue defects.
