Abstract:
The article introduces a new method of reconstruction of the lateral ligaments of the ankle. This is a modification of the well-tried tenodesis according to Evans, by which half of the tendon of the short peroneal muscle is retained as a dynamic stabilizer of the ankle. In this method, the tendon of the short peroneal muscle is cut in half about five fingers' breadth above the ankle, the incision being effected as a J-shaped cut behind the fibula; the incision goes distally beyond the proximal retinaculum of the peroneal muscle. A hole of 4.5 mm. is drilled diagonally forwards and downwards at an angle of about 50 degree. The half of the tendon is pushed forwards through this hole in the bone and sutured onto itself below the superior peroneal retinaculum, the foot being held in slightly eversed position. Like many non-anatomical methods of repair, this method is used with good results. 91 reconstructions of the lateral ligaments of the ankle have been performed from 1972 to 1980 in the Medical College Hannover. Of the 76 patients checked in follow-up examinations, 68 showed good results, while the balance of 8 patients was classified as satisfactory.
