[Repair of defects in the Achilles tendon with the peroneus brevis muscle (author's transl)].

The authors report a dynamic plastic repair of the Achilles tendon in cases of neglected rupture: The peroneus brevis muscle is used to bridge the gap. The muscle remains intact at the proximal end, its tendon is dissected immediately above its insertion, then pulled through the calcaneus by a bore-hole and fastened to itself and to the ends of the Achilles tendon. If a plantaris tendon exists, it may be used to strengthen the defect by resecting it as far as possible proximally and then fanning it out to cover the gap. The distal end of the peroneus brevis tendon is sutured side-by-side to the peroneus longus tendon. This technique was first applied in 1968. During the last 5 years 8 patients underwent repair of the Achilles tendon by this method at the Department of Orthopaedic Surgery at the University of Kiel. In all cases the results obtained were good or excellent. The patients were very content and returned to a comparable level of preoperative activity. They were able to go as well on tip-toes as on the heels, though dorsal extension in several cases was slightly restricted. Calf atrophy up to 3 cm was found in several cases, which, however, was due partly to preoperational influences. In two cases wound healing complications occured without disturbing the functional results. The authors can recommend their technique, which seems to be superior to other methods especially in difficult cases with large gaps and unfavourably anatomic conditions.
