Humerus Shaft Fracture
Medical term: Humeral Diaphyseal Fracture
Overview
A humerus shaft fracture is a break in the middle portion of the upper arm bone, between the shoulder and the elbow. These fractures can result from a direct blow, a fall, or a twisting injury and are seen across all age groups. One important consideration with this injury is the proximity of the radial nerve, which can be stretched or bruised at the time of fracture, potentially causing temporary weakness or numbness in the hand.
At our San Diego orthopedic practice, we carefully assess each humerus shaft fracture for associated nerve injury and overall fracture alignment. Many of these fractures are effectively treated with a functional brace that allows controlled motion while the bone heals. When surgery is indicated, options include plate fixation or intramedullary nailing, both of which provide reliable stabilization and allow earlier rehabilitation.
