Objective?To investigate the surgical method and clinical efficacy of repairing whole-hand destructive injury or hand degloving injury with the transplant of pedis compound free flap.?Methods?From February 2003 to June 2008, 21 patients with whole-hand destructive injury or hand degloving injury were treated, including 15 males and 6 females aged 18-45 years old (average 25 years old). The injury was caused by punching machine crush in 10 cases, roller crush in 7 cases, and imprinter crush in 4 cases. The time between injury and operation was 1-9 hours. Eleven cases had the skin-degloving injury of the whole hand, while the other 10 cases had the proximal palm injury combined with dorsal or palmar skin and soft tissue defect. After debridement, the size of wound was 9 cm × 7 cm - 15 cm × 10 cm in the dorsal aspect and 10 cm × 7 cm -16 cm × 10 cm in the palmar aspect. The defect was repaired by the thumbnail flap of dorsalis pedis flap and the second toenail flap of dorsalis pedis flap in 5 cases, the thumbnail flap of dorsalis pedis flap and the second toe with dorsalis pedis flap in 4 cases, and bilateral second toe with dorsalis pedis flap in 12 cases. The flap area harvested during operation ranged from 6 cm × 5 cm to 16 cm × 11 cm. Three fingers were constructed in 2 cases and two fingers in 19 cases. Distal interphalangeal joint toe amputation was conducted in the thumbnail flap donor site, metatarsophalangeal joint toe amputation was performed in the second toenail flap donor site, and full-thickness skin grafting was conducted in the abdomen.?Results?At 7 days after operation, the index finger in 1 case repaired by the second toenail flap suffered from necrosis and received amputation, 1 case suffered from partial necrosis of distal dorsalis pedis flap and recovered after dressing change, and the rest 42 tissue flaps survived. Forty-three out of 44 reconstructed fingers survived. All the wounds healed by first intention. At 2 weeks after operation, 2 cases had partial necrosis of the donor site flap and underwent secondary skin grafting after dressing change, the rest skin grafts survived, and all the wounds healed by first intention. Nineteen cases were followed up for 6-36 months (average 11 months). The flaps of palm and dorsum of hand showed no swelling, the reconstructed fingers had a satisfactory appearance and performed such functions as grabbing, grasping, and nipping. The sensory of the flaps and the reconstructed fingers recovered to S2-S4 grade. The donor site on the dorsum of the foot had no obvious scar contracture, without obvious influence on walking.?Conclusion?For the whole-hand destructive injury or hand degloving injury, the method of transplanting pedis compound free flap can repair the defect in the hand and reconstruct the function of the injured hand partially. It is an effective treatment method.

The flap size of lateral leg and dosalis pedis ranged from 4 cm×10 cm to 7 cm×10 cm and from 5 cm×10 cm to 9 cm×12 cm, respectively.Resutls Six cases were treated and followed up for 6 weeks to 1 year. The transplanted flaps survived with satisfactory recovery in function and appearance of theburned hand. The function of donor lower extremity was not damaged. Conclusion The procedure of the free multiple flaps of lower extremity based on the anterior tibial vascular pedicle is reliable and effective for primaryrepair of burned hand.
Objective To summarize and review the development and experience of anastomosis vascular pedicle free composite tissue flap. Methods From July 1987 to March 2007， 321 patients with complete records were treated. Fourteen tissue flaps were applied for the repair of trauma or tumor excision defects of the body, and for organ reconstruction. Results Vascular crisis occurred in 20 patients within 48 hours postoperatively. Necrosis occurred at flap end in 6 patients. The total survival rate was 94.8%. The main experience was: ① Training to grasp the basic microvascular anastomosis technique was very importantstarting up period for surgeons. The basic technique should be often practiced to ensure the safty of clinical application. ②Restoring appearance and function were equally important in practice.③Utilizing the minimal invasive methods and decreasing the loss of function of donor site were important for improvement of reconstruction quality. The purpose was to achieve functional and esthetic restoration in the condition of lowest donor site scarification. Conclusion The application of free composite tissue flap is important for the development of plastic surgery. There are extensive applications for free flap, especially for those critical patients. The application of free flap could decrease the mobility rate, shorten the treatment period, ease the pain of patients and improve the reconstruction effect. The experience of donor site selection, the strategy of poor recipient site condition, the advantages and disadvantages of muscle flap, the applications time, infections wound treatment and application, are helpful for the future application.
Objective To investigate the surgical method and effectiveness of repairing traumatic metacarpophalangeal joint defect by the composite tissue flap autograft of the second metatarsophalangeal joint. Methods Between June 2005 and December 2009, 6 cases (6 fingers) of traumatic metacarpophalangeal joint defect were treated with the composite tissue flap autograft of second metatarsophalangeal joint (containing extensor tendon, flexor tendon, proper digital nerve, planta or dorsal flap). All patients were males, aged 18-48 years, including 3 cases of mechanical injury, 2 cases of crush injury, and 1 case of penetrating trauma. The 2nd, 3rd, and 4th metacarpophalangeal joints were involved in defects in 2 cases, repectively, and defects ranged from 1.5 cm × 1.5 cm to 3.0 cm × 2.5 cm in size. All patients had skin and soft tissue defects, and defects ranged from 4 cm × 2 cm to 5 cm × 4 cm in size; and 5 cases complicated by extensor tendon defect (2.5-5.0 cm in length), 3 cases by flexor tendon rupture, and 3 cases by common palmar digital nerve injury. The time from injury to admission was 2-6 hours. Results The composite tissue flaps and skin grafts survived in all cases. All incisions healed by first intention. All patients were followed up 1-5 years. The X-ray films showed good healing between the transplanted metatarsophalangeal joint and metacarpals and phalanges at 9-14 weeks postoperatively. The appearance, colour, and texture of the skin flap were satisfactory, and the senses of pain and touch were recovered. The palmar flexion range of transplanted metacarpophalangeal joints was 50-70°, and the dorsal extension range was 5-10° at last follow-up. According to the functional assessment criteria of upper limb formulated by the Hand Surgery Branch of Chinese Medical Association, the results were excellent in 4 cases, good in 1 case, and fair in 1 case, and the excellent and good rate of 83.3%. No dysfunction of the donor foot was observed. Conclusion The metatarsophalangeal joint composite tissue flap can provide bone, nerve, skin, muscles, and tendons, so it is an effective approach to repair the metacarpophalangeal joint defect and to recover the function of the injured joints in one operation.
Objective To investigate the approach of using a nasolabial flap in conjunction with an auricular composite tissue flap with the skin on the dorsal aspect of the auricle excised for the restoration of full-thickness defects of the nasal ala following the removal of basal cell carcinoma. Methods The data of unilateral nasal alar full-thickness defect after basal cell carcinoma surgery at Department of Plastic and Burn Surgery of West China Hospital, Sichuan University between January 2016 and January 2018 were selected. All patients had full-thickness defects of the unilateral nasal ala after surgery. According to the size of the defect, the nasal labial sulcus flap combined with the auricular composite tissue flap with the skin on the back of the auricle removed was used for nasal ala repair and reconstruction in the first stage. The pedicle division of the flap was performed in the second stage one month after the surgery. The observation contents included: the survival situation of the flap and the auricular composite tissue flap, the recurrence situation of the tumor, the appearance of the affected nasal ala, the scar situation in the surgical area, and the patient satisfaction. Results A total of 18 patients were included. Among them, there were 5 males and 13 females. All 18 patients were followed up for 36 months postoperatively. The postoperative flaps and auricular composite tissue flaps survived favorably, and no tumor recurrence was detected. The contour of the affected nasal ala was satisfactory, the surgical scars were inconspicuous, and the nasofacial angle was effectively maintained. All patients expressed satisfaction with the appearance of the nose and the facial profile. Conclusions The two-stage surgical repair protocol involving the use of a nasolabial flap in combination with an auricular composite tissue flap with the skin on the back of the auricle removed for repairing the full-thickness defect of the nasal ala after basal cell carcinoma of the nasal ala is straightforward in execution. It can yield a favorable nasal ala appearance postoperatively and adequately safeguard the nasofacial angle from impairment. Thus, it merits extensive application and promotion.
