The objective of this chapter is to introduce the shoulder pain. The shoulder is a complex structure from which a comprehensive history (including mechanism of injury, characterization of pain, previous therapies, etc.) and physical examination must be obtained to appropriately evaluate the origin of the pain. Shoulder pain may originate from within the shoulder joint itself or periarticular structures, or it may refer from the cervical spine, chest, or even organs. The presentation of shoulder pain varies according to the etiology. Clavicular fractures on palpation will reveal point tenderness or an obvious deformity. Proximal humeral fractures exhibit crepitus over the fracture site and often with ecchymosis 24–48 hours after the injury. Scapular fractures usually are associated with a significant trauma.
