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.
【Abstract】 Objective To investigate the operative techniques and cl inical results of repairing the soft tissue defectsof forearm and hand with free peroneal perforator-based sural neurofasciocutaneous flap. Methods From May 2006 toJanuary 2007, 6 patients including 5 males and 1 female were treated. Their ages ranged from 22 years to 51 years. They were injured by motor vehicle accidents (2 cases), or crushed by machines (4 cases), with skin defect of hand in 1 case, skin defect of hand associated with tendon injuries and metacarpal fractures in 2 cases, skin defect of forearm in 2 cases, and forearm skin defects with fractures of radius and ulna in 1 case. The areas of soft tissue defect ranged from 16 cm × 7 cm to 24 cm × 10 cm. The debridement and the primary treatment to tendons or bones were performed on emergency. And free flaps were transplanted when the wound areas were stable at 4 to 7 days after the emergent treatment. During the operation, the flaps were designed along the axis of the sural nerve nutrient vessels according to the shape and size of the soft tissue defects, with the peroneal perforator above the lateral malleolus as the pedicle and along with a part of the peroneal artery for vascula anastomosis. Then the flaps were harvested and transferred to the reci pient sites with the peroneal vartey anastomosed to the radial (or ulnar) artery and the peroneal veins to one of the radial (or ulnar) veins and the cephal ic vein, respectively. The flap size ranged from 18 cm × 8 cm to 25 cm × 12 cm. The donor areas were closed by skin grafts. Results The 5 flaps survived after the surgery. Partial inadequate venous return and distal superficial necrosis happened in only 1 case, which also got secondary heal ing by changing dressing and anti-infective therapy. The donor sites reached primary heal ing completely. The followed-up in all the patients for 6 to 13 months revealed that the appearance and function of the flaps were all satisfactory, and no influence on ambulation of donor site was found. Conclusion Peroneal perforator-based sural neurofasciocutaneous flap has the advantages of favourable appearance, constant vascular pedicle, rel iable blood supply, large size of elevation and minor influence on the donor site. And the free transfer of this flap is an ideal procedure to repair the large soft tissue defects of forearm and hand.

Objective To investigate the operative procedures and cl inical outcomes of the modified superficial peroneal neuro-fasciocutaneous flap in repairing soft tissue defect of forefoot. Methods From May 2006 to May 2009, 5 male patients (aged 40-63 years) with soft tissue defect of forefoot were treated with the modified superficial peroneal eurofasciocutaneous flap. Tendons and bones were exposed in all cases. Defect was caused by object crash (4 cases) and traffic accident (1 case). The sizes of soft tissue defects of forefoot were 4 cm × 2 cm-8 cm × 4 cm. Rotating point of the modified superficial peroneal neuro-fasciocutaneous flap pedicled with the peripheral vessels network of ankle joint was at the level of tibiotalar joint. The flaps ranging from 5 cm × 4 cm to 10 cm × 6 cm were adopted to repair soft tissue defects of forefoot. The donor sites were either sutured directly or covered with intermediate spl it thickness skin grafts. Results All flaps survived and all wounds healed by first intention. Skin graft at donor site survived completely in all cases. All patients were followed up 6-18 months (mean 11 months). The appearance, texture, and function of the flap were satisfactory. There was a protective sensibil ity in all flaps without abrasion or ulceration, and the two-point discrimination of the flaps was 10-13 mm. The walking pattern was normal. No obvious discomfort was observed at the skin-graft donor sites. Conclusion With rel iable blood supply, no sacrifice of vascular trunks, favorable texture, and thickness, the modified superficial peroneal neuro-fasciocutaneous flap pedicled with the peripheral vessels network of ankle joint is useful to repair skin soft tissue defect of the forefoot.
ObjectiveTo investigate the effectiveness of using radial mid-forearm perforator fasciocutaneous flap to repair soft tissue defect in lower segment of the forearm and the wrist.
MethodsBetween May 2007 and July 2012, 7 cases of soft tissue defect of lower segment of the forearm and the wrist were repaired with radial mid-forearm perforator fasciocutaneous flap. There were 6 males and 1 female with an average age of 38 years (range, 22-45 years). Defects were caused by crushing injury in 4 cases with the disease duration of 3-22 days (mean, 14 days), by internal fixation of ulnar comminuted fracture in 2 cases after 16 and 20 days of operation respectively, and by focal cleaning of wrist joint tuberculosis in 1 cases after 24 days of operation. The locations of defect were the lower segment of the forearm in 5 cases and the dorsal side of the wrist in 2 cases. The area of soft tissue defect ranged from 4 cm×3 cm to 9 cm×5 cm. The size of flap ranged from 6 cm×4 cm to 12 cm×6 cm. The donor site was closed with direct suturing or skin grafting.
ResultsThe intraoperative blood loss was 50-90 mL (mean, 64 mL); the operation time was 60-80 minutes (mean, 72 minutes). Six flaps survived with wound heal ing by first intention; partial flap necrosis occurred in 1 case, and delayed healing was obtained after dressing change. Skin grafting at donor sites survived with healing of incision by first intention. The patients were followed up 3-14 months (mean, 9 months). No ulcer or sinus tract was observed; all flaps showed a sl ightly swollen appearance and had normal color.
ConclusionRadial mid-forearm perforator fasciocutaneous flap does not need to dissect the source of blood vessels due to constantly anatomical structure. It has the advantages of easy operation, rich blood supply, high survival rate, and satisfactory cl inical effect, so it is an important supplement of the other non-main vessel pedicle flaps to repair soft tissue defect in the lower segment of the forearm and the wrist.
ObjectiveTo investigate the operative method of repairing soft tissue defect of the thumb with modified radial dorsal fasciocutaneous flap and its effectiveness.MethodsBetween June 2015 and December 2016, 15 patients with volar or dorsal defects of the thumb were treated with modified radial dorsal fasciocutaneous flaps which distal pedicles were cut off. Of 15 cases, 11 were male and 4 were female, aged 35-70 years (mean, 46 years). The causes of injury included crush injury in 12 cases and avulsion injury in 3 cases. Because all patients had volar or dorsal defects of the thumb which were accompanied by tendon or bone exposure, they had no condition or desire to replant. There were 12 cases of volar defect of thumb and 3 cases of dorsal defect. The area of defects ranged from 2.0 cm×1.2 cm to 3.0 cm×2.5 cm. The time between injury and operation was 16 hours to 2 days (mean, 30.4 hours). The radial dorsal fascio-cutaneous flaps of 2.3 cm×1.5 cm to 3.3 cm×2.8 cm in size were adopted to repair defects. The donor sites were directly sutured.ResultsAll flaps survived, and no severe swelling or tension blister occurred. The donor sites and wounds healed by first intention. All patients were followed up 3-12 months (mean, 6 months). The color and texture of the grafted flaps were similar to those of normal skin, with no bloated appearance. According to total active motion standard at last follow-up, the finger function was excellent in 8 cases and good in 7 cases.ConclusionModified radial dorsal fasciocutaneous flap of the thumb is a reliable flap with easy dissection and less trauma in repair of soft tissue defects of the thumbs, and satisfactory clinical outcome can be obtained.
Objective To investigate the operative techniques and cl inical results of the superficial peroneal neurofasciocutaneous flap based on the distal perforating branch of peroneal artery in repairing donor site defect of forefoot. Methods From March 2005 to October 2007, 15 patients (11 males and 4 females, aged 20-45 years with an average of 33.6 years) with finger defects resulting from either machine crush (12 cases) or car accidents (3 cases) were treated, including 12 cases of thumb defect, 2 of II-V finger defect and 1 of all fingers defect. Among them, 6 cases were reconstructed with immediate toe-to-hand free transplantation after injury, and 9 cases were reconstructed at 3-5 months after injury. The donor site soft tissue defects of forefoot were 6 cm × 4 cm-12 cm × 6 cm in size, and the superficial peroneal neruofasciocutaneousflaps ranging from 10 cm × 4 cm to 14 cm × 6 cm were adopted to repair the donor site defects after taking the escending branch of the distal perforating branch of peroneal artery as flap rotation axis. The donor sites in all cases were covered with intermediate spl it thickness skin grafts. Results All flaps survived and all wounds healed by first intention. All reconstructed fingers survived completely except one index finger, which suffered from necrosis. Over the 6-18 months follow-up period (mean 11 months), the texture and appearance of all the flaps were good, with two-point discriminations ranging from 10-13 mm, and all patients had satisfactory recovery of foot function. No obvious discomfort and neuroma were observed in the skin-graft donor sites. The feel ing of all the reconstructed fingers recovered to a certain degree, so did the grabbing function. Conclusion Due to its rel iable blood supply, no sacrifice of vascular trunks, favorable texture and thickness and simple operative procedure, the superficial peroneal neurofasciocutaneous flap based on the distal perforating branch of peroneal artery is effective to repair the donor site defect in forefoot caused by finger reconstruction with free toe-to-hand transplantation.
