  • EFFECTIVENESS OF HAMSTRING TENDON AND FLEXOR HALLUCIS LONGUS TENDON AUTOGRAFT FOR Achilles TENDON DEFECTS RECONSTRUCTION

    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.

  • RECONSTRUCTION OF CHRONIC Achilles TENDON RUPTURE WITH FLEXOR HALLUCIS LONGUS TENDON HARVESTED USING A MINIMALLY INVASIVE TECHNIQUE

    Objective To evaluate the effectiveness of flexor hallucis longus tendon harvested using a minimally invasive technique in reconstruction of chronic Achilles tendon rupture. Methods Between July 2006 and December 2009, 22 patients (22 feet) with chronic Achilles tendon rupture were treated, including 16 males and 6 females with a median age of 48 years (range, 28-65 years). The disease duration was 27-1 025 days (median, 51 days). Twenty-one patients had hoofl ikemovement’s history and 1 patient had no obvious inducement. The result of Thompson test was positive in 22 cases. The score was 53.04 ± 6.75 according to American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score system. MRI indicated that the gap of the chronic Achilles tendon rupture was 4.2-8.0 cm. A 3 cm-long incision was made vertically in the plantar aspect of the midfoot and a 1 cm-long transverse incision was made in a plantar flexor crease at the base of the great toe to harvest flexor hallucis longus tendon. The flexor hallucis longus tendon was 10.5-13.5 cm longer from tuber calcanei to the end of the Achilles tendon, and then the tendon was fixed to the tuber calcanei using interface screws or anchor nail after they were woven to form reflexed 3-bundle and sutured. Results Wound healed by first intention in all patients and no early compl ication occurred. Twenty-two patients were followed up 12-42 months (mean, 16.7 months). At 12 months after operation, The AOFAS ankle and hindfoot score was 92.98 ± 5.72, showing significant difference when compared with that before operation (t= —40.903, P=0.000). The results were excellent in 18 cases, good in 2 cases, and fair in 2 cases with an excellent and good rate of 90.9%. No sural nerve injury, posterior tibial nerve injury, plantar painful scar, medial plantar nerve injury, and lateral plantar nerve injury occurred. Conclusion Chronic Achilles tendon rupture reconstruction with flexor hallucis longus tendon harvested using a minimally invasive technique offers a desirable outcome in operative recovery, tendon fixation, and complications.

  • RECONSTRUCTION OF CHRONIC ACHILLES TENDON RUPTURE WITH FLEXOR HALLUCIS LONGUS TENDONTRANSFER

    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.
