Achillessehnenruptur
摘要
The Achilles tendon rupture is one of the most frequent tendon injuries of the lower extremities, with a prevalence of approximately 37–50 per 100,000 inhabitants per year. Men are affected five times more often than women. Risk factors include chronic tendon degeneration, systemic diseases, such as diabetes mellitus and rheumatic diseases, medications containing corticosteroids and quinolone, obesity and nicotine abuse. Conservative treatment is feasible if ultrasound confirms secure adaptation of the tendon stumps in 20° plantarflexion of the foot. Various open and percutaneous suture techniques are available for surgical treatment. The risks of infection, wound healing complications and sural nerve injuries during surgery must be balanced against the advantage of a generally more stable healing outcome after surgical treatment. The rerupture rate after surgical treatment is significantly lower, ranging from 2–5%, compared to 4–13% after conservative treatment, which also carries a risk of elongation and secondary insufficiency. The decision for conservative or operative treatment should be carried out individually, taking patient age, activity level, occupational and sporting demands, rupture configuration and comorbidities into account. Early functional treatment is considered the standard both in conservative management of Achilles tendon ruptures and postoperative care.
