The humerus, or upper-arm bone, is one of the most commonly broken bones in both children under 12 and adults over 60. A break in the bone most often happens in the shaft of the bone, in the area between the shoulder joint and the elbow. However, a hard fall on an outstretched hand can cause a fracture in the proximal humerus, the area where the bone meets the shoulder joint. Fractures of the humerus represent about 4 to 5 percent of all fractures.
Causes and Risk FactorsCauses
A direct blow to the arm or a fall on an outstretched hand are the most common causes of a fractured humerus. Degenerative bone diseases such as osteoarthritis or a lack of calcium raise the risk of suffering a broken arm from a fall. Risk Factors
Age over 60, obesity, low bone density, and contact sports such as football or hockey heighten the likelihood of a fractured humerus.
