Stress fractures of the clavicle are rare. This is the report of one such f
racture in a 10 year old female gymnast, who presented with a six week hist
ory of medial clavicular pain. Radiographs and a computed tomography scan s
howed an undisplaced fracture through the medial third of the clavicle exte
nding inferiorly to the rhomboid fossa in the inferior aspect of the clavic
le. Pathological fracture was excluded by magnetic resonance imaging. The p
atient was treated conservatively and was able to return to full training e
ight weeks later.
