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 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 evaluate the clinical result of allogeneic tendon in treatment of chronic Achilles tendon rupture.Methods FromJuly 1996 to November 2000, 6 cases of chronic Achilles tendon rupture were treated by use of allogeneic flexor tendon to repair Achilles tendon with Bosworth way. Five cases were followed up 27-53 months with an average of 38.5 months.Results According to Arner-Lindholm criteria for curative result, the result was excellent in 1 case and good in 4 cases.Conclusion Allogeneic tendonin repair of chronic Achilles tendon is effective. It can avoid the injury and complication caused by autograft.
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.
ObjectiveTo explore the effectiveness of posterior median longitudinal W-shaped incision combined with layer-by-layer combing suture in the treatment of acute closed Achilles tendon rupture.MethodsThe clinical data of 32 patients with acute closed Achilles tendon rupture who met the selection criteria between August 2015 and February 2019 were retrospectively analyzed. There were 25 males and 7 females, with an average age of 33 years (range, 21-48 years). All of them were closed rupture of Achilles tendon caused by sports injury. Physical examination on admission: the rupture space of Achilles tendon was palpable; Thompson sign was positive; the rupture of Achilles tendon was confirmed by MRI and ultrasonography before operation, the distance between the broken end and the insertion point of Achilles tendon was 2-8 cm, with an average of 3.5 cm. The average time from injury to operation was 2.7 days (range, 1-10 days). During the operation, the posterior median longitudinal W-shaped incision of Achilles tendon was used to expose the broken end of Achilles tendon, and the deep and shallow double Kessler end-to-end suture+layer-by-layer combing suture were used to suture the Achilles tendon, and the skin incision was sutured by “V-Y”advancement. The postoperative complications were observed; the healing of Achilles tendon was observed by ultrasonography; at last follow-up, Arner Lindholm criteria was used to evaluate ankle function.ResultsThe 32 patients were followed up 8-24 months, with an average of 12 months. The incision healed by first intention, without the complications of skin necrosis, nonunion, delayed healing, and infection, scar hyperplasia or ulcer, and symptom of peroneal nerve injury. No Achilles tendon rupture and deep infection occurred during the follow-up period. The ultrasonography examination showed that the Achilles tendon was healing. At last follow-up, according to Amer Lindholm evaluation standard, the results of ankle function was excellent in 26 cases and good in 6 cases.ConclusionThe treatment of acute closed Achilles tendon rupture with a posterior median longitudinal W-shaped incision combined with deep and shallow double Kessler end-to-end suture+layer-by-layer combing suture is effective, which can fully exposed the incision, the quality of Achilles tendon anastomosis is reliable, and it can effectively avoid wound complications and iatrogenic injury of gastrocnemius nerve.
Objective To explore the effectiveness of anterolateral thigh fasciocutaneous flap for repair of skin and soft tissue defect and simultaneous Achilles tendon reconstruction with modified methods of ilio-tibial bundle suture. Methods Between October 2009 and June 2011, 10 cases of Achilles tendon and soft tissue defects were treated. There were 7 males and 3 females, aged from 5 to 60 years (median, 40 years). Injury was caused by spoke in 5 cases, by heavy pound in 3 cases, and by traffic accident in 2 cases. The time between injury and admission was 2-24 hours (mean, 8 hours). The size of wound ranged from 11 cm × 7 cm to 18 cm × 10 cm; the length of Achilles tendon defect was 4-10 cm (mean, 7 cm). Three cases complicated by calcaneal tuberosity defect. After admission, emergency debridement and vacuum sealing drainage were performed for 5-7 days, anterolateral thigh fasciocutaneous flap transplantation of 11 cm × 7 cm to 20 cm × 12 cm was used to repair skin and soft tissue defects, and improved method of ilio-tibial bundle suture was used to reconstruct Achilles tendon. The flap donor site was closed directly or repaired with skin grafting to repair. Results All flaps and the graft skin at donor site survived, healing of wounds by first intention was obtained. All patients were followed up 6-18 months (mean, 10 months). The flap was soft and flexible; the flap had slight encumbrance in 3 cases, and the others had good appearance. At last follow-up, two-point discrimination was 2-4 cm (mean, 3 cm). The patients were able to walk normally. The range of motion (ROM) of affected side was (24.40 ± 2.17)° extension and (44.00 ± 1.94)° flexion, showing no significant difference when compared with ROM of normal side [(25.90 ± 2.33)° and (45.60 ± 1.84)° ] (t=1.591, P=0.129; t=1.735, P=0.100). According to Arner-Lindhoim assessment method for ankle joint function, all the patients obtained excellent results. Conclusion A combination of anterolateral thigh fasciocutaneous flap for repair of skin and soft tissue defects and simultaneous Achilles tendon reconstruction with modified methods of ilio-tibial bundle suture is beneficial to function recovery of the ankle joint because early function exercises can be done.
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.
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.
ObjectiveTo investigate the effectiveness of autogenous tendon reconstruction under total arthroscopy in the treatment of chronic Achilles tendon rupture.MethodsBetween June 2015 and June 2018, 16 patients with chronic Achilles tendon ruptures were treated by autogenous tendon reconstruction under total arthroscopy. Of the 16 patients, 11 were males and 5 were females. Their mean age was 40.7 years (range, 21-55 years). The disease duration was 14-20 months (mean, 16.4 months). Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 41.2±2.2 and the pain visual analogue scale (VAS) score was 7.9±1.2. MRI and B-ultrasonography examinations showed that the Achilles tendon was not continuous. The length of Achilles tendon defect was 5.0-10.3 cm, with an average of 5.8 cm. The rupture of the Achilles tendon happened on top of the insertion of the tendon in 4 cases and at the tendon-muscle belly connection in 12 cases. The operation time, intraoperative blood loss, hospital stay, and related complications were recorded. The AOFAS score and VAS score were used to evaluate the improvement of ankle joint function and pain.ResultsThe average operation time was 77.2 minutes (range, 60-90 minutes). The average intraoperative blood loss was 20.5 mL (range, 15-30 mL). The average hospital stay was 7.2 days (range, 5-10 days). All incisions healed by first intention. There was no skin necrosis, infection, or deep vein thrombosis. All the patients were followed up 8-18 months, with an average of 12 months; and 10 cases were followed up more than 12 months. During the follow-up, there was no Achilles tendon re-rupture, and the symptoms of pain and heel lifting failure significantly improved. MRI reexamination showed that the continuity of Achilles tendon recovered. At 1, 3, 6, and 12 months postoperatively, AOFAS scores significantly improved and VAS scores significantly reduced, except for 1 month postoperatively, the scores at other time points were superior to that before operation, the differences were significant (P<0.05).ConclusionAutogenous tendon reconstruction under total arthroscopy in the treatment of chronic Achilles tendon rupture has the advantages of small trauma, rapid functional recovery, and satisfactory surgical efficacy.
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.
