Objective To evaluate the effectiveness of interference screw and flexor hallucis longus tendon as augmentation material in repair of chronic Achilles tendon rupture. Methods From October 2004 to June 2007, 32 patients (35 feet) with chronic Achilles tendon rupture were treated, including 21 males (22 feet) and 11 females (13 feet) and aging 32-85 years. The disease course was 4-132 days. There were 29 patients with hoofl ike movements history and 3 patients withoutobvious inducement. The result of Thompson test was positive in 31 cases (33 feet). The score was 56.09 ± 7.25 according to the American Orthopaedic Foot and Ankle Society ankle-hindfoot scoring system (AOFAS). MRI indicated that the gap of the chronic Achilles tendon rupture was 0.5-5.0 cm. Medial foot incision associated with medial heel incision or only medial heel incision was made to harvest flexor hallucis longus tendon. The tendon should be 3 cm longer than the end of the Achilles tendon, then fix the tendon to the calcaneus. Results Wound dehiscence occurred and wound healed after dressing change in 1 case; wound healed by first intention in other patients. Thirty-two patients were followed up for 12-32 months (mean 19.4 months). The AOFAS score was 94.22 ± 4.63, showing statistically significant difference when compared with that before operation (P lt; 0.01). The results were excellent in 28 cases, good in 3 cases and fair in 1 case. No sural nerve injury, posterior tibial nerve injury, plantar painful scar, medial plantar nerve injury and lateral plantar nerve injury occurred. Conclusion Flexor hallucis longus tendon transfer offers a desirable outcome in operative recovery, tendon fixation and compl ications.
Objective To report the clinical result of the improvedisland skin flap with distallybased sural nerve nutrient vessels in repairing skin defect in the heel, ankle or foot. Methods From August2004 to April 2005, 15 patients with skin defect in the heel, ankle or foot at distal part were treated by the improved island skin flap with distally-based of sural nerve nutrient vessels. Of 15 flaps, 12 were simplex flaps and 3 were complex flaps. These flap area ranged from 7 cm×6 cm to 11×8 cm. The donor sites were sutured directly and covered with free flap. Results All flaps survived without flap swelling and disturbance of blood circulation. The wounds of donor and recipient sites healed by first intention. The followup period ranged from 3 to 6 months. The texture of flap was soft and the color of flap was similar to that of normal skin. The foot function was excellent. Conclusion The improved island skin flap with distally-based sural nerve nutrient vessels is an ideal skin flap for repairing skin defect in the heel, ankle or foot distal part in clinical. The operation is simple and need not to anastomose blood vessel.
Objective To investigate the effectiveness of groin flap combined with medial plantar artery perforator flap (MPAP) for degree Ⅲ-Ⅳ defects of multiple fingers. Methods Between January 2018 and June 2019, 12 patients with degree Ⅲ-Ⅳ defects of multiple fingers caused by crushing were admitted. There were 9 males and 3 females with a median age of 29 years (range, 16-42 years). The mean interval between the injury and admission was 3 hours (range, 1-9 hours). The injured fingers of 7 cases were index and middle fingers, 4 cases were middle and ring fingers, and 1 case was index, middle, and ring fingers. All fingers were taken thorough debridement and covered by the vacuum sealing drainage device during the emergency operation. The mean interval between the debridement and flap repairing was 18 hours (range, 12-36 hours). During the first-stage operation, the iliac bone graft was used to reconstruct bone frame, and the proximal interphalangeal (PIP) joint from the foot was transferred as the digital PIP joint, then the thin groin flap and MPAP were tailored to cover the dorsal and palmar defects, respectively. The size of the groin flap was 7.0 cm×4.5 cm-14.0 cm×9.0 cm, and the size of the MPAP was 8.0 cm×4.5 cm-14.0 cm×6.5 cm. The abdominal donor site was directly sutured, and the foot was repaired with full-thickness skin grafting. The flaps were separated into the finger shape at the second-stage. Results All the flaps survived, and the wounds healed by first intention; the incisions in the donor site healed by first intention, and the skin grafts survived completely. All patients were followed up 12-18 months (mean, 16 months). At last follow-up, the injured finger was similar to the contralateral one in terms of texture, appearance, and color. The mean two-point discrimination was 8 mm (range, 6-10 mm), and the sensate level recovered to the S3-S4. According to the Michigan Hand Outcomes Questionnaire (MHQ), the reconstructed hand function was excellent in 8 cases and good in 4 cases. There was no complication in the donor sites. Conclusion The degree Ⅲ-Ⅳ defects of multiple fingers were repaired by the groin flap and MPAP, and the reconstructed fingers can perform good texture and motion with being sensate, with less sacrifice on the foot.
目的 評價不同皮瓣、肌皮瓣修復小腿及足踝部皮膚軟組織缺損的效果，探討小腿及足踝部皮膚軟組織缺損的理想修復方法。 方法 2002年6月－2010年1月，應用15種皮瓣、肌皮瓣修復128例（138處）小腿及足踝部皮膚軟組織缺損。其中小腿中上段21處，小腿中下段45處，內外踝及足跟部43處，足背及前足29處。主要應用最多的皮瓣有腓腸神經營養血管皮瓣、腓腸肌內外側頭肌皮瓣、腓淺神經營養血管皮瓣和足底內側皮瓣。修復軟組織缺損范圍5 cm×4 cm～23 cm×14 cm。 結果 術后135處創面Ⅰ期愈合，皮瓣完全成活；2處皮瓣部分壞死，經二次手術植皮修復；1例游離股前外側皮瓣修復小腿中下段軟組織缺損，皮瓣完全壞死，后改取對側腓腸神經營養血管交腿皮瓣修復成活。腓腸神經營養血管皮瓣應用例數最多，成活率高，吻合血管的游離皮瓣壞死率較高。術后患者均獲隨訪1～10年，平均23個月，皮瓣均成活良好, 無潰瘍、滲液等。 結論 正確認識并選擇皮瓣、肌皮瓣修復小腿及足踝部皮膚軟組織缺損可提高皮瓣成活率，恢復肢體良好功能，腓腸神經營養血管皮瓣是一種修復小腿及足踝部軟組織缺損的理想皮瓣。
From 1984 to 1994, 236 different types of traumatic defects of foot were repaired by microsurgical tissue grafting. They included simple cutaneous flap in 187 and composite flap in 49. Among the 236 different tissue flaps, vascularized flap was used in 97 and pedicled flap in 139. The 4 fore-foot and 6 heel defects were repaired by composite skeleted cutaneous grafts with scapula and vascularized febula respectively. After the follow-up from 1 to 10 years, all the grafted tissues were survived and healed well. The functions were satisfactory, and 186 patients had resumed their original works. The key to good function following repair was to maintaion the integrity of foot structures and the sensation of the sole and heel.
