Objective To evaluate the effectiveness of hamstring tendon and flexor hallucis longus (FHL) tendon autograft for Achilles tendon defects reconstruction. Methods Between February 2009 and October 2011, 9 patients (9 feet) with Achilles tendon defect were treated with hamstring tendon and FHL tendon autograft. Of 9 cases, 6 were male and 3 were female with an average age of 43 years (range, 21-65 years), including 5 cases of chronic Achilles tendon ruptures caused by sport injury and 4 cases of Achilles tendon defects caused by resection of tendon lesion (2 cases of hyaline degeneration with necrosis, 1 case of giant cell tumor, and 1 case of chronic inflammation with hyaline degeneration). The disease duration ranged from 31 to 387 days (mean, 137.6 days). The defect length was 5 to 18 cm (mean, 8.6 cm). Functional exercise of the ankle began at 6 weeks after plaster fixation. Results Dehiscence and effusion occurred in 2 cases and plantar pain caused by injury of tibial nerve in 1 case; primary healing of wound was obtained in the other patients without complication. Nine patients were followed up 19.7 months on average (range, 13-25 months); no re-rupture was observed. There was no significant difference in the dorsal extension between at preoperation and at 1 year and last follow-up after operation (P gt; 0.05); the ankle plantar flexion at 1 year and last follow-up after operation was significantly larger than that at preoperation (P lt; 0.05). The ankle plantar flexion and dorsal extension at 1 year and last follow-up after operation were significantly larger than those at 3 months after operation (P lt; 0.05), but no significant difference was found between at 1 year and last follow-up (P gt; 0.05). American Orthopaedic Foot and Ankle Society (AOFAS) and short-form 36 health survey scale (SF-36) scores were significantly increased at postoperation when compared with scores at preoperation (P lt; 0.05), and the scores at last follow-up were significantly higher than those at 3 months after operation (P lt; 0.05). The Achilles tendon total rupture score (ATRS) at last follow-up was significantly higher than that at 3 months after operation (t= — 7.982, P=0.000). Conclusion Combined hamstring tendon and FHL tendon autograft is one of the effect methods to reconstruction Achilles tendon defects.
Objective To observe the clinical outcome of primary repair of the tissue defects of the Achilles tendon and skin by thigh anterolateral free flap and free iliotibial tract. Methods From January 2000 to January 2005, the thigh anterolateral free flap and the iliotibial tract were used to primarily repair the defects of the Achilles tendon and skin in 11 patients (7 males and 4 females, aged 6-45 years). The defects of the skin and Achilles tendon were found in 6 patients, and the defects of the Achilles tendonand skin accompanied by the fracture of the calcaneus were found in 5 patients.The defect of the Achilles skin was 6 cm×5cm-14 cm×8 cm in area. The defect of the Achilles tendon was 511 cm in lenth. The skin flap was 11 cm×6 cm-17 cm×11 cm in area.The iliotibial tract was 7-13 cm in length and 3-5 cm in width. The medial and lateral borders were sutured to from double layers for Achilles tendon reconstruction. The woundon the donor site could be sutured directly in 5 patients, and the others could be repaired with skin grafting. Results After operation, all the flaps survived and the wound healed by first intention. The followup of the 11 patients for 6 mouths-4 years (average, 30 months) revealed that according to Yin Qingshui’s scale, the result was excellent in 6 patients, goodin 4, and fair in 1. The excellent and good rate was 99%. The results showed a significant improvement in the “heel test” and the Thompson sign, and both were negative. No complications of ulceration on the heel and re-rupture of the Achiles tendon occurred. Conclusion The primary repair of the tissue defects of the Achilles tendon and skin by free grafting of the anterolateral femoral skin flap and the iliotibial tract is an effective surgical method.
ObjectiveTo investigate the effectiveness of anterolateral femoral flap in combination with fascia lata grafting in repair of large Achilles tendon and skin defects.MethodsThe clinical data of 18 patients with large Achilles tendon and skin defects repaired with anterolateral femoral flap in combination with fascia lata grafting between January 2018 and January 2019 were retrospectively reviewed. There were 14 males and 4 females; age ranged from 32 to 57 years (mean, 42.1 years). There were 9 cases of postoperative infection of Achilles tendon rupture, 1 case of traffic accident injury, and 8 cases of combined infection of skin and Achilles tendon defects after heel trauma. The length of Achilles tendon defect was 4-8 cm, with an average of 5.6 cm; the range of the skin defect was 14 cm×3 cm to 20 cm×5 cm. Flap survival was observed, and ankle function recovery was evaluated according to McComis functional assessment criteria, and dorsal extension and plantar flexion mobility of the affected limb were measured at last follow-up and compared with those of the healthy side.ResultsEighteen cases were followed up 8-24 months, with an average of 16.7 months. All the flaps survived after operation, the flaps were soft and elastic, and the incisions healed by first intention. At last follow-up, 15 cases were excellent, 2 cases were good, and 1 case was acceptable according to McComis functional evaluation criteria, with an excellent and good rate of 94.4%. The two-point discrimination of the heel posterior region of the affected foot was 4-7 mm, with an average of 5.32 mm. The heel-raise test was negative. The dorsiflexion range of the affected side was (21.55±1.26)°, which was significantly different from that of the healthy side (25.23±1.45)° (t=8.128, P=0.000); the plantar flexion of the affected side was (44.17±1.52)°, which was not significantly different from that of the healthy side (46.13±1.31)° (t=0.444, P=0.660).ConclusionThe application of anterolateral femoral flap in combination with fascia lata grafting for the repair of large Achilles tendon and skin defects can achieve good effectiveness.
