[Care of chronic rupture of the fibular ligaments using the Weber method of reconstruction at the ILF].

After an inadequate conservative treatment of III-grade sprain of the ankle combined with the rupture of ligaments, these heal in prolongation which result in the chronic instability of the ankle joint. After the evaluation of the anamnesis and the objective examination the diagnosis is specified by comparative forced X-ray images in both projections. To substitute insufficient fibular ligaments we use a modification of the Weber method. We perform tenodesis of m. peronaeus brevis. The tendon is led through the bone channel above the apex of the lateral maleolus and its proximal end is fixed in the area of the origin of lig. fibulotalare anterius to talus. We checked up 29 patients on average 4 years and 7 months after the operation. From the subjective viewpoint almost 80 per cent patients had no or minimum complaints. In the examination of the range-of-motion; we found in 52 per cent of patients the range identical with the intact side, in 41 per cent there occurred functionally insignificant limitation of inversion. On the basis of longterm satisfactory results we can recommend our modification of the Weber method as a simple and efficient method of the treatment of chronical instability of the ankle joint.
