Objective:To explore the clinical effect and safety of intal fixation of steel-wire limited loop in earlyAchilles tendon rupture.Methods:Seventy-six patients respectively with early transected and avulsed types ofAchilles tendon rupture were selected and treated with intal fixation of steel-wire limited loop.The patients began to take exercise for their lower limbs through continous passive motion as early as possible after surgical repair, and the loops were removed after3-5 months.Six months later, the condition of complications includingAchilles tendon re-rupture, wound fistula, wound infection and skin necrosis, cutaneous sensation in sural nerve dominance region, time back to preinjury work or leing as well as time to physical activities were observed.One year later, the therapeutic effect was evaluated, and the maximum circumferences of bilateral legs and ruptured plane circumferences ofAchilles tendon were measured.Results:The wound of all patients healed well, no complications likeAchilles tendon re-rupture, wound fistula, wound infection and skin necrosis occured, and the cutaneous sensation in sural nerve dominance region was normal.The mean time back to preinjury workor leing as well as to pysical activities of all patients were respectively10 and22 weeks.Seventy out of76 patients(92.1%) achieved an excellent effect, and6(7.9%) good effect.The excellent and good rate came up to100%.The maximum circumference in the affected leg decreased to 2 mm averagely compared with the offside, while the ruptured plane circumferences ofAchilles tendon in the affected side increased to2.2 mm compared with the offside.Conclusions:For earlyAchilles tendon rupture, intal fixation of steel-wire limited loop can recover the ankle function better, ret to the preinjury state in the shortest time, and has few complications.
