Objective To investigate of effectiveness of free fascia lata flap assisted by indocyanine green angiography (ICGA) in treatment of Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures. Methods A clinical data of 14 patients with Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures between March 2020 and June 2024 was retrospectively analyzed. All Achilles tendon defects were repaired with the free fascia lata assisted by ICGA during operation. There were 12 males and 2 females with an average age of 45.4 years (range, 26-71 years). The causes of Achilles tendon rupture included sports injury in 10 cases, Achilles tendon-related tendinopathy in 3 cases, and glass laceration injury in 1 case. The time from Achilles tendon rupture to operation was 4-40 weeks (median, 4.5 weeks). Preoperative MRI examination showed that the defect length of the Achilles tendon was 2-5 cm (mean, 3.2 cm). The operation time and intraoperative blood loss were recorded. The color Doppler ultrasound (CDU) and MRI were taken to observe the foot blood vessels and the tendon healing. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, Achilles Tendon rupture score (ATRS), and range of motion of the ankle joint were used to estimate the pain and function of ankle joint. Results All operations of the 14 patients were successfully completed. The operation time ranged from 3.00 to 4.50 hours (mean, 3.60 hours). The intraoperative blood loss ranged from 10 to 50 mL (mean, 36.4 mL). After operation, 1 patient had exudation at the recipient site, which healed after dressing change; the other incisions healed by first intention. All incisions at the donor sites healed by first intention. All patients were followed up 6-36 months (mean, 11.4 months). The CDU of the foot at 1 month after operation showed that the blood flow signal of the perforating vessels of the fascia lata flap was clear. The ankle MRI at 2 months after operation showed the good continuity of the Achilles tendon. No complication such as the Achilles tendon re-rupture, ankle stiffness, or scar contracture occurred during follow-up. Compared with preoperative score, the AOFAS score, ATRS score, and plantar flexion range of motion significantly increased at 1, 3, and 6 months after operation (P<0.05), while the VAS score and dorsiflexion range of motion significantly decreased (P<0.05). The AOFAS score, ATRS score, and VAS score at 3 and 6 months further improved when compared with those at 1 month (P<0.05); however, there was no significant difference in the range of motion of the ankle joint (P>0.05). There was no significant difference in above indicators between 3 and 6 months after operation (P>0.05). Conclusion The treatment of Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures with free fascia lata flaps under the guidance of ICGA has the advantages of precise design, fast healing, and a wide range of adaptability.

Objective To evaluate a modified anterolateral thigh fascial flap designed for the treatment of the soft tissue defects in the forearmsand hands. Methods From September 2000 to December 2003, a modified anterolateral thigh fascial flap combined with the intermediate split thickness skin graft was applied to the treatment of 13 patients with the soft tissue defects in the forearms or the hands. There were 8 males and 5 females, aged 19-43 years (average, 27.6 years). Three patients had a mangled injury, 4 had a belt injury, and 6 had a crush injury; 6 patients had their tissue defects on the palm side of the forearm, 6 had their tissue defects on the dorsal side of thehand, and 1 had the defect in the index finger (dorsal side of the hand). The tissue defects ranged in size from 17.5 cm×7.7 cm to 4.6 cm×3.4 cm.In addition, 4 of the patients had an accompanying fracture in the forearm or the hand,and the remaining 9 had an extenor tendon injury. All the patients underwent emergency debridement and reposition with an internal fixation for the fracture; 3-5 days after the repair of the injured nerves, muscle tendons and blood vessels, the tissue defects were repaired with the anterolateral thigh fascial flap combined with the intermediate split thickness skin graft. Results No vascular crisis developed after operation. All the flaps survived except one flap that developed a parial skin necrosis (2.0 cm ×1.0 cm) in the hand, but the skin survived after another skingrafting. The follow-up for 3-12 months revealed that all the flaps and skin grafts had a good appearance with no contracture of the skin. According to the evaluation criteria for the upper limbs recommended by the Hand Society of Chinese Medical Association, 9 patients had an excellent result, 2 had a good result, 1 had a fair result, and 1 had a poor result, with a good/excellence rate of 85%. Conclusion The modified anterolateral thigh fascial flap combined with the skin graft is one of the best methods for the treatment of the soft tissue defects in the forearms and the hands. This method has advantages of no requirement for a further flap reconstruction, no skin scar or contracture in the future, easy management for the donor site, and less wound formation.
Repairs of the wornds arter cicatricial resection in 15 cases of claw hands after burn by retrograde transfer of posterior interosscous vascularized fascial flap, of forearm were reported. 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 observe the clinical effect of repairing rectovaginal septum with graft of fascia flap with blood vessels. Methods From August 2004 to August 2006, 12 female patients with rectocele were treated,aging 49-73 years. The disease course was from 5 to 30 years(mean, 5.6 years). All patients suffered dysporia. X-rayfilms showed severe rectocele (≥30 mm), or with the descendent perineum syndrome(≥40 mm), and inner pendant rectal mucosa (3 cases) and/or narrow anal canal (9 cases).The size of fascia flap ranged from 15 cm×3 cm to 18 cm×5 cm. Results The bleeding amount was 800 ml in 2 cases, and 500 ml in 10 cases. All fascia flaps survived. In the 12 patients, 11 had a primary wound healing(Stage Ⅰ), 1 had a delayed wound healing(Stage Ⅱ). The donor sites healed at Stage Ⅱ. Twelve patients could defecate normally 46 days after surgery. The legs edema occurred in 2 cases, urinary retention combined with infection occurred in 1 case. And all recovered completely after treatment. Eleven patients were followed up for 6 to 12 months. Digital anorectal examination showed prerectal pouch disappearance, glaze surface and good elasticity. Xray films and CT showed that the rectocele disappeared. Conclusion The operation of repairing rectovaginal septum with graft of fascia with blood vessels can effectively recover anatomy of rectovaginal septum and its normal biological function.
ObjectiveTo investigate the feasibility of the free descending branch of lateral circumflex femoral artery perforator tissue flap (fascia flap plus skin flap) to repair large soft tissue defects of the extremities and its impact on the donor site. MethodsBetween January 2013 and February 2015, 9 cases of large tissue defects of the extremities were repaired with the free descending branch of lateral circumflex femoral artery perforator tissue flap. There were 8 males and 1 female, aged from 13 to 56 years (median, 36 years). The causes included traffic accident injury in 6 cases and crushing injury by heavy object in 3 cases. Soft tissue defect located at the lower limbs in 7 cases and at the upper limbs in 2 cases, including 2 cases of simple tendon exposure, 2 cases of simple bone exposure, and 5 cases of tendon and bone exposure. After debridement, the soft tissue defect area ranged from 13 cm×7 cm to 20 cm×18 cm. The tissue flaps ranged from 14 cm×8 cm to 23 cm×19 cm. The donor site was directly sutured, scalp graft was used to cover the fascia flap. ResultsAfter operation, partial necrosis of the skin grafting on the fascia flap occurred in 2 cases and healed after dressing change. Arterial crisis occurred in 1 case and the flap survived after anastomosis. The other tissue flaps survived and wounds healed by first intention. The skin grafting healed by first intention in 7 cases, by second intention in 2 cases. The patients were followed up 4-24 months (mean, 10 months). The appearance and function of the tissue flaps were satisfactory, only linear scar was observed at the donor site, which had less damage and no effect on walking. ConclusionFree descending branch of lateral circumflex femoral artery perforator tissue flap can repair large soft tissue defect of the extremities. The donor site can be sutured directly, which reduces damage to donor site and is accord with the principle of plastic surgery.
