Humerus fracture also cause deformity, and they typically limit the ability to flex the elbow. Humerus fractures usually occur after physical trauma, falls, excess physical stress, or pathological conditions. 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. Proximal humerus fractures most often occur among elderly people with osteoporosis who fall on an outstretched arm. Less frequently, proximal fractures occur from motor vehicle accidents, gunshots, and violent muscle contractions from an electric shock or seizure. Other risk factors for proximal fractures
Humerus fracture Humerus fractures usually occur after physical trauma, falls, excess physical stress, or pathological conditions such as tumors. Falls are the most common cause of proximal and shaft fractures, and those who experience a fracture from a fall usually have an underlying risk factor for bone fracture. Distal fractures occur most frequently in children who attempt to break a fall with an outstretched hand. Fractures of the humerus may be classified by the location into proximal region, which is near the shoulder, the middle region or shaft, and the distal region, which is near the elbow. These locations can further be
