The proximal end of your humerus is the top. The distal end is the bottom. So, if you have a proximal humerus fracture, your upper arm bone is broken near its top — the end that connects to your shoulder. Similarly, if you have a distal humerus fracture that means your bone is broken at the bottom, closer to your elbow.
Fractures of the humerus are classified in one of two ways: proximal humerus fracture or humerus shaft fracture. A proximal humerus fracture usually occurs close to the shoulder joint and can be located at different levels with different fracture patterns: simple or comminuted.
Symptoms vary depending on the specific type of fracture but may include: Deformity — “It does not look right.” What is the treatment for a humerus fracture? Most fractures of the proximal humerus can be treated without surgery if the bone fragments are not shifted out of position (displaced).
With distal humerus fractures, if the elbow is flexed less than 90 degrees, a transcolumnar fracture is seen and a direct posterior injury results in an olecranon fracture compared to elbow flexion greater than 90 degrees with an intercondylar fracture.
