OBJECTIVE: To review the anatomy, etiology, therapy strategy of Achilles tendon injury and its related advances in recent years. METHODS: The related articles in recent years were extensively reviewed. RESULTS: There still were many arguments about the effect of corticosteroid on the treatment of tendon disease. Fluoqmnolone was found to be related with Achilles tendon injury. Acute rupture of Achilles tendon could be treated with open operation, percutaneous repair, or conservative therapy. For old rupture, many kinds of operations could be selected. CONCLUSION: The growth factors found in recent years provide us with new prospect for future treatment of Achilles tendon injury.
Objective To investigate the management of the soft tissue defect after the Achilles tendon repair. Methods From April 1996 to April 2006, 24 patients(17 males, 7 females; aged 16-59 years), who suffered from postoperative Achilles tendon exposure caused by local soft-tissue necrosis after the Achilles tendon repair, were treated and evaluated. Of the 24patients, 8 had an original open injury (machinecrush injury in 2 patients, heavy-object press injury in 3, motorcycle wheel crush injury in 3) and 16 patients had a closed injury (sports injury). In their treatment, the transferof the sural neurovascular flap was performed on 8 patients and the transfer ofthe saphenous neurovascular flap was performed on 3 patients. The secondary Achilles tendon repair was performed on 13 patients before the neurovascular flap transfer was performed. The time between the injury and the operation was 9-76 days, and the time between the Achilles tendon expousure and the operation was 3-65 days. Results All the flaps survived and the Achilles tendon exposure was well covered by the flaps of good texture. Eighteen patients followed up for 6 months to 24 months had no flap complication, and the two point discrimination of the flaps was 12-20 mm. The AOFASAnkleHindfoot Scale assessment revealed that 8 patients had an excellent result, 6 had a good result, 3 had a fair result, and just 1 had a poor result, with theexcellent and good results accounting for 77.8%. Sixteen patients (89%) were able toperform a tip-toe stance on their operative sides, and only 3 of them complained a loss of plantarflexion strength. However, 2 patients still could not perform the tip-toe stance. Conclusion The Achilles tendon repair, ifnot well performed, can result in the local soft-tissue necrosis and the subsequent Achilles tendon exposure. If those complications occur, the neurovascular flap transfer should be performed as soon as possible; if necessary, the secondary Achilles tendon repair should be performed, too.
Objective To investigate the appl ication and cl inical result of flap in the repair of wounds with Achilles tendon exposure. Methods Between May 2006 and May 2010, 21 patients with Achilles tendon skin defects were treated with microsurgical reconstruction. There were 15 males and 6 females, aged 7-63 years with a median of 34 years. The defect causesincluded sport injury in 4 cases, wheel twist injury in 7 cases, crush injury in 5 cases, chronic ulcer in 3 cases, and Achilles tendon lengthening in 2 cases. The areas of wounds with Achilles tendon exposure ranged from 2 cm × 2 cm to 10 cm × 8 cm. After debridement, wounds were repaired with the medial malleolus fasciocutaneous flap (5 cases), sural neurocutaneous vascular flap (8 cases), foot lateral flap (2 cases), foot medial flap (2 cases), and peroneal artery perforator flap (4 cases). The size of the flaps ranged from 3 cm × 3 cm to 12 cm × 10 cm. The donor sites were either sutured directly or covered with intermediate spl it thickness skin grafts. The Achilles tendon rupture was sutured directly (2 cases) or reconstructed by the way of Abraham (2 cases). Results All flaps survived and wounds healed by first intention except 2 flaps with edge necrosis. Twenty-one patients were followed up 6-18 months (mean, 12 months). The flaps had good appearance and texture without abrasion or ulceration. The walking pattern was normal, and the two point discrimination was 10-20 mm with an average of 14 mm. The Ameritan Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale assessment revealed that 10 patients had an excellent result, 7 had a good result, 3 had a fair result, and 1 had a poor result with an excellent and good rate of 81.0%. Fourteen cases could l ift the heels with power; 5 cases could l ift the heels without power sl ightly; and 2 cases could not l ift the heels. Conclusion The wounds with Achilles tendon exposure should be repaired as soon as possible by appropriate flap according to the condition of wound.
Objective To compare the effectiveness of the 3 methods (traditional open Achilles tendon anastomosis, minimally invasive percutaneous Achilles tendon anastomosis, and Achilles tendon anastomosis limited incision) for acuteAchilles tendon rupture so as to provide a reference for the choice of cl inical treatment plans. Methods Between December 2007 and March 2010, 69 cases of acute Achilles tendon rupture were treated by traditional open Achilles tendon anastomosis (traditional group, n=23), by minimally invasive percutaneous Achilles tendon anastomosis (minimally invasive group, n=23), and by Achilles tendon anastomosis l imited incision (l imited incision group,n=23). There was no significant difference in gender, age, mechanism of injury, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score between 3 groups (P gt; 0.05). Results Minimally invasive group and limited incision group were significantly better than traditional group in hospital ization days and blood loss (P lt; 0.01). Incision infection occurred in 2 cases of traditional group, and healing of incision by first intention was achieved in all patients of the other 2 groups, showing significant difference in the complication rate (P lt; 0.05). Re-rupture of Achilles tendon occurred in 1 case (4.3%) of minimally invasive group and limited incision group respectively; no re-rupture was found in traditional group (0), showing significant difference when compared with the other 2 groups (P lt; 0.05). All cases were followed up 12-18 months with an average of 14.9 months. The function of the joint was restored. The AOFAS score was more than 90 points in 3 groups at 12 months after operation, showing no significant difference among 3 groups (P gt; 0.05). Conclusion The above 3 procedures can be used to treat acute Achilles tendon rupture. However, minimally invasive percutaneous Achilles tendon anastomosis and Achilles tendon anastomosis limited incision have the advantages of less invasion, good heal ing, short hospital ization days, and less postoperative complication, and have the disadvantage of increased risk for re-rupture of Achilles tendon after operations.
OBJECTIVE To investigate the clinical result and influence factors of prognosis after repair of ruptured Achilles tendon with operative treatment. METHODS From 1961 to 1994, 62 cases with ruptured Achilles tendon were treated operatively. Among them, "8"-shaped suture was used in 8 cases, aponeurosis flap repair in 30 cases, transfer repair of tendon of peroneus longus muscle in 2 cases, reverse "V-Y" shaped tendon plastic operation in 10 cases, and mattress suture of opposite ends in 12 cases. RESULTS Followed up 3 to 33 years, there was excellent in 40 cases, better in 13 cases, moderate in 6 cases, poor in 3 cases, 85.5% in excellent rate. Postoperative infection and re-rupture were occurred in 6 cases respectively. CONCLUSION Different operative procedures are adopted to achieve better long-term clinical result according to the injury types.
Old achilles tendon rupture accompanied by skin defect was a common amp; annoying problem in clinic. From June, 1985 to June, 1996, 18 cases with this kind of injury were treated by one stage repair of the tendon and skin defect. In this series, there were 15 males and 3 females, the length of tendon defects were ranged from 4 cm-6.1 cm, and the area of skin defect were ranged from 5.9 cm x 3 cm to 8.2 cm x 6 cm. The procedures were: (1) to debridement of the wound thoroughly; (2) to repair the achilles tendon; (3) to repair the skin defect with kinds of pedicle flap; (4) immobilization of ankle and knee for 6 weeks. No infection was occured after the operation. The flaps survived in all cases. After follow-up for one year in 15 cases, 12 patients went back to their work. It was concluded that (1) achilles tendon rupture should be treated carefully and properly during the emergency operation; (2) different methods should be selected according to the length of tendon defect; (3) because of its high survival and retained sensation after operation, the flap pedicled with posterior lateral malleolar artery is the best choice for repairing the skin defect.
OBJECTIVE: To explore the methods of treatment for old achilles tendon rupture merging with skin defect. METHODS: By following up retrospectively 10 patients from February 1995 to December 2001, we analyzed the operative methods, the points for attention and the results. Gastrocnemius musculocutaneous flaps were used in 3 cases, foot lateral skin flaps in 4 cases, superior medial malleolus skin flaps in 2 cases, and sural neural skin flap in 1 case. The Achilles tendon was sutured directly in 8 patients, with Lindholm’s technique in 2 patients. RESULTS: All flaps survived and the wound healed well in 8 cases and reruptured in 2 cases. According to Yin Qing-shui’s criteria to test the efficacy, the results were excellent in 5 patients, good in 4 and poor in 1. CONCLUSION: Repairing the old Achilles tendon rupture merging with skin defect by use of microsurgery has good results and plays an important role in reducing joint contracture and stiffness, and in saving the ability to push forward and flex.
