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.
ObjectiveTo investigate the effectiveness of dorsalis pedis flap series-parallel big toe nail composite tissue flap in the repairment of hand skin of degloving injury with tumb defect. MethodsBetween March 2009 and June 2013, 8 cases of hand degloving injury with thumb defect caused by machine twisting were treated. There were 7 males and 1 female with the mean age of 36 years (range, 26-48 years). Injury located at the left hand in 3 cases and at the right hand in 5 cases. The time from injury to hospitalization was 1.5-4.0 hours (mean, 2.5 hours). The defect area was 8 cm×6 cm to 15 cm×11 cm. The thumb defect was rated as degree I in 5 cases and as degree II in 3 cases. The contralateral dorsal skin flap (9 cm×7 cm to 10 cm×8 cm) combined with ipsilateral big toe nail composite tissue flap (2.5 cm×1.8 cm to 3.0 cm×2.0 cm) was used, including 3 parallel anastomosis flaps and 5 series anastomosis flaps. The donor site of the dorsal flap was repaired with thick skin grafts, the stumps wound was covered with tongue flap at the shank side of big toe. ResultsVascular crisis occurred in 1 big toe nail composite tissue flap, margin necrosis occurred in 2 dorsalis pedis flap;the other flaps survived, and primary healing of wound was obtained. The grafted skin at dorsal donor site all survived, skin of hallux toe stump had no necrosis. Eight cases were followed up 4-20 months (mean, 15.5 months). All flaps had soft texture and satisfactory appearance;the cutaneous sensory recovery time was 4-7 months (mean, 5 months). At 4 months after operation, the two-point discrimination of the thumb pulp was 8-10 mm (mean, 9 mm), and the two-point discrimination of dorsal skin flap was 7-9 mm (mean, 8.5 mm). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the results were excellent in 4 cases, good in 3 cases, and fair in 1 case. The donor foot had normal function. ConclusionDorsalis pedis flap series-parallel big toe nail composite tissue flap is an ideal way to repair hand skin defect, and reconstructs the thumb, which has many advantages, including simple surgical procedure, no limitation to recipient site, soft texture, satisfactory appearance and function of reconstructing thumb, and small donor foot loss.
OBJECTIVE: To investigate the clinical results of the medial multiplex flap pedicled with the posterior tibial vessel. METHODS: Twelve cases with soft tissue defects and bone defects of limbs were treated with the medial multiplex flap pedicled with the posterior tibial vessel from September 1992 to May 1999. Among them, bone and soft tissue defects following opened fracture in 7 cases, chronic ulcer following chronic osteomyelitis in 2 cases, melanoepithelioma in 2 cases, bone and soft tissue defects following osteoma resection in 1 case. The bone defect area was from 2.5 cm x 5.0 cm to 4.5 cm x 11.0 cm. Free graft was performed in 5 cases, bridged transposition in 3 cases and reversal transposition in 4 cases, among them, periosteal myocutaneous flap with autogenous or allogeneic bone grafting in 8 cases, myocutaneous flap in 4 cases. The area of the flaps from 6 cm x 8 cm to 12 cm x 25 cm. RESULTS: All flaps were healed by first intention, but in the distal fragments of bigger flaps were partially necrosed in 2 cases. In 10 cases bone healing were obtained after 16 weeks of operation according to the X-ray photos. All cases were followed up from 6 to 18 months. All cases achieved satisfactory result but 1 case died because of lung metastasis of osteoma. CONCLUSION: The multiplex graft pedicled with the posterior tibial vessel is an ideal graft for repairing the large soft tissue defects and bone defects, because it has such advantages as adequate blood supply, big vascular diameter, long pedicle and big dermatomic area.
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.
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.
