Simple bone cysts are asymptomatic, benign lesions which are usually a
n incidental finding on a radiograph. Etiology and treatment are contr
oversially discussed. The weightbearing status of the calcaneus and po
ssible pathologic fracturing lead many authors to recommend therapeuti
c measures after diagnosis has been made. We present a case report of
an intact unicameral bone cyst of the calcaneus concomitant with tibia
l and talar fractures following crush trauma. Several types of treatme
nt for simple bone cysts of the calcaneus have been suggested. The que
stion whether treatment is unconditionally necessary is controversiall
y discussed. It is the author's opinion, that asymptomatic bone cysts
of the calcaneus require no further treatment.
