An olecranon fracture is a break in the bony "tip" of the elbow. Because the olecranon is positioned directly under the skin with little protection from muscles or other soft tissues, it can break easily if you experience a blow to the elbow or fall on an outstretched arm.| orthoinfo.aaos.org
Osteoarthritis of the elbow can happen because of a previous injury such as elbow dislocation or fracture. Most commonly, however, it is the result of a normal wearing away of the joint cartilage from age and activity.| orthoinfo.aaos.org
