[Long-term results following subcutaneous Achilles tendon rupture].

From 1972 to 1982, 132 ruptures of the achilles tendon were treated at the Orthopedics Division, University of Heidelberg. Surgical treatment was carried out in 125 cases, and seven patients were treated conservatively. The average age of the patients was 42 years. 84% of the achilles tendon ruptures occurred during sport. After an average investigation period of 6.5 years, 33 patients could be followed up. The rate of complications and the final functional results are communicated. The blood supply to the achilles tendon is described separately. Twelve cadaver achilles tendons were investigated by means of the plastination method. It could be demonstrated that a reduced blood supply to the Achilles tendon is present about 3-5 cm above the calcaneal tuber. This finding corresponds to the most frequent site of rupture. It is unclear to what extent there is a connection between the blood supply and the rupture site of typical locations.
