Shoulder Trauma (Fractures and Dislocations) OrthoInfo AAOS
Fractures are broken bones Fractures commonly involve the clavicle (collarbone), proximal humerus (top of the upper arm bone), and scapula (shoulder blade) Dislocations occur when the bones on opposite sides of a joint do not line up Dislocations can involve any of three different joints A dislocation of the acromioclavicular joint (collarFracture terms (use in all other cases): Conchoidal Fracture surface is a smooth curve, bowlshaped (common in glass); Hackly Fracture surface has sharp, jagged edges; Uneven Fracture surface is rough and irregular; Fibrous Fracture surface shows fibres or splinters Notes: The number of cleavage planes can differ from mineral to mineralGeology rocks and minerals
