Humerus Fracture: lateral view and PA view

Fractures of the proximal humerus are common in elderly with a history of osteoporosis following a FOOSH. Humerus shaft fractures (pictured here) usually occur as a result oftrama in younger patients. In this case, there is approximately 10% varus angulation, and a look at the lateral view shows anterior displacement. Clinically, look for localized pain, swelling, tenderness and shortening of the upper extremity. Radial injury is common, so look for a wrist drop.

Radial head fracture are the most common fracture of the elbow, usually resulting from fall on the outstretched hand. Pain profile includes lateral elbow tenderness and pain, and inability to fully extend the elbow.
