BACKGROUND Stress fracture of the clavicle is a rare entity. It can manifest itself with an atypical shoulder pain. The clavicle is vulnerable to pathological fractures from several causes such as neoplasm, infection and rarely metabolic bone disease. METHODS We report a case of a bone insufficiency fracture of the clavicle, in a 67-year-old Moroccan woman patient with several risk factors of bone insufficiency including osteoporosis, osteomalacia and primary hyperparathyroidism. CONCLUSIONS The diagnosis of bone insufficiency-related fracture of the clavicle can be challenging. It should be considered in the differential diagnosis of shoulder or clavicle pain.
