The function of the hand was improved. The deformities were corrected by arthroplasty or arthodesis. The applied anatomy and operatirc techniques were introduced. The intraoperative problems were discussed.
Objective To introduce the application of the scrotal flap on reconstructing partial urethra defect. Methods From March 1998 to August 2004, 31 patients with urethra defect were treated with scrotal flap. Their ages ranged from6 to 34 years. Thirty-one patients included 8 cases of congenital deformity of urethra and 23 cases of complication of urethral fistula, urethral stenosis and phallus bend after hypospadias repair. The flap widths were 1. 2. cm in child and 2.3. cm in adult. The flap lengthwas 1. -2.0 times as much as the width. Nine cases were classified as penile type, 10 cases as penoscrotal type, 7 cases as scrotal type(3 children in association withcleft scrotum) and -cases as perrineal type because of pseudohermaphroditism.Urethroplasty was given by scrotal fascia vascular net flap to reconstruct urethra defect. Results All the flaps survived, and the incision healed well. Twenty four cases achieved healing by first intention and 7 cases by second intention. And fistula occurred and healed after 2 weeks in 1 case. 27 cases were followed up 14 years, 2 cases had slight chordee, the others were satisfactivly. Conclusion Urethroplasty with scrotal fascia vascular net flap is an ideal method for the partial defect urethra.
OBJECTIVE: To evaluate the clinical efficacy of fasciocutaneous flap in the repair of the III degree burn wound in the facio-cervical region. METHODS: From January 1997 to October 2001, 11 cases of III degree burn wounds in the facio-cervical region were repaired with the cervical-thoracic fasciocutaneous flap ranging from 18 cm x 8 cm to 13 cm x 5 cm. Donor sites were covered with "Z" plasty or skin grafting. RESULTS: Except for partial necrosis of distal end of the flap in 1 case, the flaps in the other 10 cases all survived and presented satisfactory appearance and function during the following up. CONCLUSION: The fasciocutaneous flap in the cervical-thoracic region may provide a large area of flap, and can be easily transferred. It’s an ideal flap for the repair of skin defect in the facio-cervical region, especially for the repair of the wounds with infection or exposure of vessel, nerve and tendon.
The ultra length and width random calf fasciocutaneous flaps whose blood supply came from the calf fasciocutaneous vascular network were transposed in 9 cases for the treatment of severe trauma of leg. All of the flaps survived except one having necrosis of the distal fourth. The length and width of the flap to the width of the pedicle were 6.1∶1 and 2.7∶1 respectively. Properly extended the area and decreased of blood perfusion of the flan would reduce the burden of the venous backflow to the flap relatively. The abundant vascular networks of the calf fasciocutaneous flap was a very important factor that this type of flap would possibly survive.

Objective To explore the effectiveness of anterolateral thigh fasciocutaneous flap for repair of skin and soft tissue defect and simultaneous Achilles tendon reconstruction with modified methods of ilio-tibial bundle suture. Methods Between October 2009 and June 2011, 10 cases of Achilles tendon and soft tissue defects were treated. There were 7 males and 3 females, aged from 5 to 60 years (median, 40 years). Injury was caused by spoke in 5 cases, by heavy pound in 3 cases, and by traffic accident in 2 cases. The time between injury and admission was 2-24 hours (mean, 8 hours). The size of wound ranged from 11 cm × 7 cm to 18 cm × 10 cm; the length of Achilles tendon defect was 4-10 cm (mean, 7 cm). Three cases complicated by calcaneal tuberosity defect. After admission, emergency debridement and vacuum sealing drainage were performed for 5-7 days, anterolateral thigh fasciocutaneous flap transplantation of 11 cm × 7 cm to 20 cm × 12 cm was used to repair skin and soft tissue defects, and improved method of ilio-tibial bundle suture was used to reconstruct Achilles tendon. The flap donor site was closed directly or repaired with skin grafting to repair. Results All flaps and the graft skin at donor site survived, healing of wounds by first intention was obtained. All patients were followed up 6-18 months (mean, 10 months). The flap was soft and flexible; the flap had slight encumbrance in 3 cases, and the others had good appearance. At last follow-up, two-point discrimination was 2-4 cm (mean, 3 cm). The patients were able to walk normally. The range of motion (ROM) of affected side was (24.40 ± 2.17)° extension and (44.00 ± 1.94)° flexion, showing no significant difference when compared with ROM of normal side [(25.90 ± 2.33)° and (45.60 ± 1.84)° ] (t=1.591, P=0.129; t=1.735, P=0.100). According to Arner-Lindhoim assessment method for ankle joint function, all the patients obtained excellent results. Conclusion A combination of anterolateral thigh fasciocutaneous flap for repair of skin and soft tissue defects and simultaneous Achilles tendon reconstruction with modified methods of ilio-tibial bundle suture is beneficial to function recovery of the ankle joint because early function exercises can be done.
Objective To evaluate clinical significance of reversed sural neurovascular fasciocutaneous flap for reconstruction of softtissue defects in ankle and foot. Methods From July 1994 to December 2002, 52 cases of soft-tissuedefects in the ankle and foot were reconstructed by use of reversed sural neurovascular fascio-cutaneous flap, including 47 cases of traumatic defects, 3 cases of chronic ulcer and 2 cases of tumors. The flap area ranged from 4 cm×6 cm to 10 cm×21 cm. Results The flaps survived in 48 cases; the distal part necrosed and secondary free-skin graft were further conducted in 4 cases. All soft-tissue defects were repaired and their accompanied bone and tendon exposurehealed. Forty-six cases were followed-up for 5 months to 48 months, the color and texture of the flaps were excellent and 2point discrimination was 11-17 mm(14 mm on average).The functions of ankle joints were good.Conclusion The reversedsural neurovascular fascio-cutaneous flap is convenient in design and dissection. Its use can retained and replace vascular anostomosed flaps to certain degrees.
OBJECTIVE In order to increase the survival area of pedicled fasciocutaneous flap, a multiple pedicled blocking randomized fasciocutaneous flap was designed. METHODS From January 1991 to September 1998, this technique was used to repair 33 cases, including 27 males and 6 females and the ages ranged from 6 to 58 years. All of the patients were suffered from traffic accidents. In these cases, 22 cases had skin defects of legs and feet with bone, nerve and tendon exposed, 5 cases had osteomyelitis as well as internal fixaters exposed and the other 6 had deformity from scar. The size of the flap was 25.0 cm x 13.0 cm x 2.4 cm at its maximum and 6.0 cm x 3.5 cm x 1.5 cm at its minimum. Based on the traditional blocking flap, according to the severity of the wound and conditions of the neighboring tissues, a flap having 2 to 4 orthogonal pedicles with a width of 1.5 to 3.0 cm was designed. The medical-graded stainless steel sheet was implanted below the deep fascia, and after blocking for 3 to 6 days, the side pedicles were divided. 6 to 14 days later, one of the two remaining pedicles was divided and was transferred to repair the defect. RESULTS 31 cases were followed up for 6 months to 5 years without any trouble of the joints. The flap had a good external appearance and was high pressure-resistant. CONCLUSION The multiple pedicled blocking randomized fasciocutaneous flap increased the size of the flap and the length to width ratio. It had the following advantages: manage at will, high resistance to infection and a large survival area of flap.
Objective To evaluate the effect of internal fixation on the stability of pedicled fascial flap and the osteogenesis of exceed critical size defect (ECSD) of bone so as to provide theory for the clinical application by the radiography and histology observation. Methods The ECSD model of the right ulnar midshaft bone and periosteum defect of 1 cm in length was established in 32 New Zealand white rabbits (aged 4-5 months), which were divided into group A and group B randomly (16 rabbits in each group). The composite tissue engineered bone was prepared by seeding autologous red bone marrow (ARBM) on osteoinductive absorbing material (OAM) containing bone morphogenetic protein and was used repair bone defect. A pedicled fascial flap being close to the bone defect area was prepared to wrap the bone defect in group A (control group). Titanium miniplate internal fixation was used after defect was repair with composite tissue engineered bone and pedicled fascial flap in group B (experimental group). At 2, 4, 6, and 8 weeks, the X-ray films examination, morphology observation, and histology examination were performed; and the imaging 4-score scoring method and the bone morphometry analysis was carried out. Results All rabbits survived at the end of experiment. By X-ray film observation, group B was superior to group A in the bone texture, the space between the bone ends, the radiographic changes of material absorption and degradation, osteogenesis, diaphysis structure formation, medullary cavity recanalization. The radiographic scores of group B were significantly higher than those of group A at different time points after operation (P lt; 0.05). By morphology and histology observation, group B was superior to group A in fascial flap stability, tissue engineered bone absorption and substitution rate, external callus formation, the quantity and distribution area of new cartilage cells and mature bone cells, and bone formation such as bone trabecula construction, mature lamellar bone formation, and marrow cavity recanalization. The quantitative ratio of bone morphometry analysis in the repair area of group B were significantly larger than those of group A at different time points after operation (P lt; 0.05). Conclusion The stability of the membrane structure and the bone defect area can be improved after the internal fixation, which can accelerate bone regeneration rate of the tissue engineered bone, shorten period of bone defect repair, and improve the bone quality.
