The authors present the case of a teenager who suffered left humerus fracture due to stress while he was pitching a baseball game. Humerus fractures caused by stress are infrequent. They commonly occur in athletes practicing throwing sports, being more frequent in amateur baseball pitchers with little experience. This lesion is due to uncoordinated muscular traction and torsion strength when the ball is thrown, all associated to physical fatigue. It can happen at the level of the medial and upper third of the humerus, between the insertions of deltoids and pectoral major muscles, and also in the distal third. The presence of pain is common a little before the fracture happens. The authors emphasize in the importance of taking into account the possibility of this kind of fracture occurring in athletes practicing throwing sports, and also the complications appearing after this kind of lesion. Data collected from the patient?s clinical record were analyzed. It is important to think in this kind of lesion because sometimes clinical characteristics are not evident. It was also pointed out the necessity of performing a strict follow-up of the patient given the possibility of radial nerve lesion.
