Fracture of the sternum--an unusual case.

Stress fracture of the sternum is a rare injury and can occur in young athletes due to repeated stress and in elderly with osteoporotic bones or other pathological conditions under normal stress. A case of a 14-year-old boy is reported who sustained fracture of the sternum without any history of significant trauma when he simply tried to lift his whole body over his arms and felt pain in front of the chest.
