1、Acute Achilles Tendon Rupture,Paul Herickhoff, MD March 26, 2009,Background,Largest, most powerful tendon in body Formed by gastrocnemius and soleus Incidence of rupture 18:100,000 Incidence is increasing As demonstrated by population based studies in Finland, Canada, Scotland and Sweden,Presentatio
2、n,Adults 40-50 y.o. primarily affected (MF) Athletic activities, usually with sudden starting or stopping “Snap” in heel with pain, which may subside quickly,Factors to consider,25% of patients have previous symptoms of Achilles inflammation Leppilahti et al. Clin Orthop 1998 Associated conditions:
