  • REPAIR OF COMPLICATED DEGLOVING INJURIES OF OPPOSITE FINGER WITH AKIN UNITED FLAPS PEDICLED WITH DORSAL CARPAL BRANCH OF ULNAR ARTERY

    Objective To evaluate the cl inical efficacy of akin united flaps pedicled with dorsal carpal branch of ulnar artery in repairing compl icated degloving injuries of the opposite fingers. Methods Between August 2005 and August 2009, 11 cases of compl icated degloving injuries of single finger were treated, including 8 males and 3 females with an average age of 26 years (range, 19-55 years). The defect locations were thumb in 1 case, index finger in 7 cases, and middle finger in 3 cases, including 9 cases of mechanical injury and 2 cases of traffic accident injury. The extent of skin avulsion was the proximal segments or beyond the middle segment of finger with a defect range from 5.0 cm × 4.5 cm to 8.0 cm × 5.5 cm. Compl icated injuries included phalangeal fracture in 2 cases, extensor tendon injury in 3 cases, flexor and extensor tendon injuries in 1 case, digital vascular injury in 9 cases, and digital nerve injury in 6 cases. The time from injury to operation was 2-18 hours (mean, 4.8 hours). The akin united flaps were designed on the basis of anatomical distribution of the dorsal carpal branch of ulnar artery. The proximally pedicled flaps enclosed palmar finger, and the distally pedicled flaps enclosed dorsal finger. The size of flaps ranged from 10 cm × 3 cm to 16 cm × 3 cm. The donor sites were sutured directly. After 3 weeks, the pedicle was cut. Results Light yellow secretion and eczema on the flap were observed in 1 case at 3 days, were cured after 2 weeks of dressing change; other flaps survived and healing of incisions by first intention was achieved. The incisions at donor sites healed by first intention. The secondary plastic operation was performed in 2 cases because of bulky flaps at 3 months after operation. Eleven patients were followed up postoperatively 6-12 months (8 months on average). The texture and appearance of all the flaps were satisfactory. The two-point discrimination was 12-20 mm with satisfactory recovery of finger function at 6 months after operation. According to Jebsen standard, the results were excellent in 8 cases, good in 2 cases, and poor in 1 case. Conclusion With rel iable blood supply, easy dissection, less injury at donor site, and good repair results, the akin united flaps pedicled with dorsal carpal branch ofulnar artery is a good method to repair complicated degloving injuries of the opposite fingers.

  • REPAIR OF FINGER TISSUE DEFECT WITH MODIFIED ISLAND FLAP BASED ON REVERSED DORSAL METACARPAL ARTERY

    Objective To investigate the operative procedure and the cl inical results of the modified island flap based on the reversed dorsal metacarpal artery for repairing finger tissue defect. Methods From January 2004 to March 2009, 38 patients (43 fingers) with finger tissue defect were treated with the modified island flaps based on the reversed dorsal metacarpal artery. The deverting point was altered from the dorsal point to the palm. There were 27 males (31 fingers) and 11 females (12 fingers) with an average age of 43.6 years (range, 12-67 years). Defect was caused by crash injury in 18 cases, crush injury in 14 cases, and cutting injury in 6 cases. Of them, 11 index fingers, 23 middle fingers, 7 ring fingers, and 2 l ittle fingers were involved. The area of the defect ranged from 1.0 cm × 0.7 cm to 3.2 cm × 2.5 cm. The area of flaps ranged from 1.2 cm × 1.0 cm to 3.5 cm × 2.8 cm. The donor sites were sutured directly. Results Tension vesicular scabbing occurred in distal part of flap, and was cured after dressing change in 3 cases. The other flaps survived and incision healed primarily. All incision at donor sites healed primarily. Thirty-one patients (35 fingers) were followed up 6-29 months (15.3 months on average). All flaps survived with satisfactory appearance, sensation, and function. Two-point discrimination was 6-9 mm (7.9 mm on average). The results were excellent in 20 fingers, good in 13 fingers, and fair in 2 fingers according to the total active movement (TAM) standards; the excellent and good rate was 94.3%. Conclusion The treatment of finger tissue defect with the modified island flap based on the reversed dorsal metacarpal artery is recommendable. The deverting point was altered from the dorsal point to the palm. The vessel pedicle is extended. It can be easily and conveniently performed for more cases.
