Gastrocnemius musculotendinous rupture: a condition confused with thrombophlebitis.

Over a 24-year interval I have seen 22 cases of rupture of the medial head of the gastrocnemius muscle where it inserts into the soleus aponeurosis. The rupture may result in a swelling that is easily confused with thrombophlebitis and result in unnecessary hospitalization and anticoagulant therapy with its attendant expense and possible complications. The process is self-limiting and heals without sequelae in three to six weeks.
