Conclusion The dorsalis pedis flap for hand two series of skin and soft tissue defects, with design flexibility, excellent texture flaps, etc., is to repair the hand skin and soft tissue defects of the two better way.

Objective To determine the surgical approaches and evaluate the clinical efficacy of skin defects of the emergency thumb, finger reconstruction.Methods Emergency in 11 cases complicated skin defect of the thumb and the hand, fingers missing injured patients by using the method of combined of toenail flap of biped dorsalis pedis flap or the second toe.The implantation of thumbnail flap of dorsalis pedis flap combined with the second toenail flap was applied on 5 cases.3 cases had received the implantation of thumbnail flap of dorsalis pedis flap combined with the second toe and 3 cases with combined repair of the second toe of biped dorsal flap.Of all the cases, reconstruction of 3 fingers in 1 case, reconstruction of 2 fingers in 10 cases,5 cases with reconstruction by means of implantation of toenail flap of same pediele splitting flap or the second toe, 6 cases with repair of toenail flap of dorsalis pedis flap or second toe.Results Except for 1 necrosis occurred in 1 finger in 1 case of 3 fingers reconstruction, the rest of tissue flaps and fingers all survived.The primary healing was achieved postoperatively.The patients were followed up for 5-24 months.The functions such as grabbing, grasping, nipping were basically restored after the repair.The appearance of hand was also restored to a certain degree.Sensory recovery S2-S4 of reconstruction finger and flap was achieved.Healing was satisfying in the donor area, no obvious cicatricial contracture was seen, while the walk function was not affected.Conclusion The application of combined implantation of toenail flap of biped dorsalis pedis flap or the second toe in the repair of overall hand skin degloving injury could restore the function and appearance of the injured hands to a certain degree.It is proved to be an effective treatment method.

Objective To assess the clinical efficacy of repair of thumb joints using the proximal interphalangeal joint of the second toe. Methods Proximal interphalangeal joint grafts of the second toe with vascular anastomosis were used to repair 54 fingers defects in 49 cases, including reconstruction of metacarpophalangeal joints in 21 fingers,proximal interphaiangeal joints in 28 fingers and distal interphaiangeal joints in 5 fingers, amounting to 38 fingers of entire joint transplantation and 16 fingers of semi-joint transplantation. An assessment was made for the clinical efficacy after the reconstruction. Results All 54 grafted joints in 49 cases survived. Primary postoperative healing was achieved. Followed-up from 6 to 19 months, all grafted joints clinically healed within 4 to 8 weeks. The bone healing time was 6 to 12 weeks. Degeneration of grafted joints was absent. Neither nonunion nor re-fracture was observed. The postoperative flexion activity range of proximal interphalangeal joints was 35°-90°, averaged 65°; the flexion range of metacarpophalangeal joints was 30°-75°, averaged 45°; the flexion range of distal interphalangeal joints was 25°-65°, averaged 35°. According to the joint activity criteria TAM / TAF, there were 23 grafted fingers of excellence, 25 of satisfaction, 5 of average and 3 of poor recovery. Favorable grafts accounted for 84 percent. Best efficacy was evidenced in proximal interphalangeal joint grafts, followed by metacarpophalengeal ones,whereas distal interphalangeal transplantation provided poorer outcomes. Conclusion Repair of thumb joint defects using proximal interphalangeal joint grafts of the second toe free enables favorable functional recovery and satisfying improvement of joint activities.

Objective: To investigate the clinical effects of extra-long lateral femoral supercharged perforator flaps in repair of ankle and foot wounds. Methods: From March 2014 to October 2018, 16 patients with foot and ankle injuries were admitted to our hospital and left large area of wounds on foot and ankle after emergency treatment. There were 13 males and 3 females, with age of 27 to 60 years. The area of the wounds ranged from 14 cm×10 cm to 40 cm×17 cm. The wounds were repaired with extra-long lateral femoral supercharged perforator flaps. The widths of flaps in 8 patients were longer than 8 cm, and the bilobed flaps were designed to repair the wounds. The area of the flaps ranged from 12 cm×5 cm to 40 cm×9 cm. During the operation, 54 perforators were detected, with an average of 3.2 perforators in each flap, and 36 source arteries of perforators were detected. The blood vessel trunk of 15 patients was descending branch of the lateral femoral circumflex artery, and their supercharged mode was anastomosis of the bulky perforator of descending branch of the lateral femoral circumflex artery with the oblique branch of the lateral femoral circumflex artery and/or medial femoral circumflex artery or the descending branch of superficial illiac circumflex artery. The blood vessel trunk of 1 patient was oblique branch of the lateral femoral circumflex artery, and the supercharged mode of the patient was anastomosis of the oblique branch of the lateral femoral circumflex artery with the bulky perforator of the descending branch of the lateral femoral circumflex artery. The wounds were covered with the flaps after supercharged blood vessel anastomosis, and blood vessels in the donor sites were anastomosed with those in the recipient sites. The donor site was sutured directly. The survival of the flap after the operation and healing time of the wound, and the flap condition, the two-point discrimination distance of flap in patients who were reconstructed with sensation, the recovery of the ankle function, and the appearance of the donor site during follow-up were recorded. Results: A total of 17 flaps in 16 patients were designed, including 8 bilobed flaps and 9 non-lobulated flaps. Sixteen flaps in 15 patients survived. Vascular crisis occurred in the flap of one patient, and the flap survived when the vascular crisis was relieved by the second operation. The healing time of foot and ankle wounds ranged from 12 to 90 days. All the lateral femoral donor sites healed completely. During follow-up of 8 to 48 months, flaps in 2 patients were slightly bloated and were trimmed in 6 months after the operation. The other flaps were with good appearance, soft texture, good elasticity, and no rupture or ulceration. The two-point discrimination distances of flaps ranged from 7 to 16 mm in 8 patients who were reconstructed with sensation, and the other flaps recovered protective sensation. The flexion and extension function of ankle joint recovered well, and the walking function was not affected significantly. All donor sites formed linear scar, with no deep tissue infection such as osteomyelitis. Conclusions The application of extra-long lateral femoral supercharged perforator flaps to repair the large area of wounds in foot and ankle can significantly reduce damage to donor sites and has advantages of rich blood supply and good safety, thus it has satisfactory clinical effects.
