Proximal humerus fractures most often occur among elderly people with osteoporosis who fall on an outstretched arm. Falls that produce humerus fractures among the elderly are usually accompanied by a preexisting risk factor for bone fracture, such as osteoporosis, a low bone density, or vitamin B deficiency. Humerus fractures usually occur after physical trauma, falls, excess physical stress, or pathological conditions. Distal fractures may also cause deformity, and they typically limit the ability to flex the elbow. Displaced fractures of the humerus shaft will often cause deformity and a shortening of the length of the upper arm. If the fracture affects the blood supply, then the patient will have a diminished pulse at the wrist. In cases in which the nerves are affected, then there will be a loss of control or sensation in the arm below the fracture. A crackling or rattling sound may also be present, caused by the fractured humerus pressing against itself. The fracture is typically accompanied by a discoloration of the skin at the site of the fracture. The affected region swells, with bruising appearing a day or two after the fracture. Signs and symptoms Types of major humerus fracturesĪfter a humerus fracture, pain is immediate, enduring, and exacerbated with the slightest movements. Proximal and shaft fractures generally have a good outcome while outcomes with distal fractures can be less good. Surgical options may include open reduction and internal fixation, closed reduction and percutaneous pinning, and intramedullary nailing. Many humerus shaft fractures may be treated with a brace rather than surgery. In proximal fractures that remain well aligned, a sling is often sufficient. Treatment options may include a sling, splint, brace, or surgery. A CT scan may be done in proximal fractures to gather further details. Diagnosis is generally confirmed by X-rays. Types include proximal humeral fractures, humeral shaft fractures, and distal humeral fractures. Other causes include conditions such as cancer in the bone. The cause of a humerus fracture is usually physical trauma such as a fall. Complications may include injury to an artery or nerve, and compartment syndrome. There may be a decreased ability to move the arm and the person may present holding their elbow. Symptoms may include pain, swelling, and bruising. Generally good (proximal and shaft), Less good (distal) Ī humerus fracture is a break of the humerus bone in the upper arm.
