title: Fracture of the clavicle and second rib: an indirect injury from tricep dips.
abstract: Due to the recent rise in the interest in strength training, an increment in the number of lesions is expected, whether of the tendons, muscles, or bones. We describe a case of fracture involving the middle third of the clavicle and the second rib in a low-demand weightlifter. The fractures occurred suddenly while performing a triceps dips exercise, and the patient had no previous symptoms. He was treated conservatively and was able to return to sports six months later. To our knowledge, this is the first study describing the association of these fractures triggered by a single event of muscle contraction.
