Exposures of the humerus for fracture fixation.

: The care of humeral shaft fractures is undergoing a transition to more aggressive treatment methods with more frequent operative fixation. The upper arm has an extensive network of nerves, arteries, and veins that must be protected during any operative exposure. The ultimate goal of fixation of a humerus fracture is rigid stabilization to allow early range of motion, protection of the neurovascular structures, and preservation of the triceps mechanism posteriorly and the anterior elbow flexor muscles.
