Objective To study the methods and effectiveness of repairing degloving injury of the distal phalanx with homodigital bilobed flaps tiled. Methods Between April 2008 and June 2011, 40 patients (40 fingers) with degloving injury of the distal phalanx were treated, which were caused by machine. There were 30 males and 10 females, aged from 18 to 56 years
(mean, 30 years). The time from injury to operation was 1-5 hours (mean, 2.5 hours). Affected fingers included index in 13
cases, middle finger in 11 cases, ring finger in 9 cases, and l ittle finger in 7 cases. The defect area ranged from 3.0 cm × 2.0 cm to 5.5 cm × 3.8 cm. All cases complicated by pollution and exposure of tendon and phalanx, 5 cases by phalangeal fractures, and tendon insertion had no rupture. The end dorsal branches of digital artery island flaps and digital arterial island flaps were used in 14 cases, the end dorsal branches of digital artery island flaps and near dorsal branches of digital artery island flaps in 18 cases, and the end dorsal branches of digital artery island flaps and superficial palmar digital veins arteril ization island flaps in 8 cases. The area of the upper flaps ranged from 2.0 cm × 1.5 cm to 2.6 cm × 2.2 cm and the area of the next leaf flaps ranged from 2.5 cm × 2.0 cm to 3.5 cm × 2.5 cm. The donor sites were covered with free flaps. Results Flap bl ister occurred in 13 cases and vascular crisis in 3 cases. The flaps survived in 40 cases, wound healing by first intention was achieved in 38 cases, and by second intention in 2 cases. The donor skin-grafting was survival. After operation, 30 patients were followed up 8 to 20 months with an average of 10.6 months. The flaps had satisfactory appearance and soft texture, and the finger tip had no touch pain. The sensory function of the flaps was restored at 4-6 weeks after operation; two-point discrimination was 6.0 to 10.0 mm in 24 flaps at 12-15 months. According to the total active movement (TAM) evaluation system introduced by the American Society for Surgery of the Hand in 1975, the results were excellent in 27 cases, good in 2 cases, and fair in 1 case, and the excellent and good
rate was 96.7%. Conclusion The homodigital bilobed flaps tiled for degloving injury of the distal phalanx is simple and easyto- operate with less injury.
