Olecranon Process: Bony projection of the ulna at the tip of the elbow.
Orthotic: Any device applied to or around the body in the care of physical impairment or disability, commonly used to control foot mechanics.
Osgood-Schlatter Disease (Osteochronrosis): “Growing pain” at the knee, a temporary condition creating a patellar tendonitis due to the growth of the bones being faster than the muscles.
Osteoarthritis ( also called Osteoarthrosis ,or degenerative joint disease): a disorder of the joints, characterized by progressive deterioration of the articular cartilage. It is the most common joint disease, affecting more than 80 percent of those who reach the age of 70. Although its suffix indicates otherwise, osteoarthritis is not characterized by excessive joint inflammation as is the case with rheumatoid arthritis. The disease may be asymptomatic, especially in the early years of its onset. As it progresses, however, pain, stiffness, and a limitation in movement may develop. Common sites of discomfort are the vertebrae, knees, and hips–joints that bear much of the weight of the body.
Osteochondritis Dessicans: A piece of bone and/or cartilage loosened from its attachment after trauma and a cause of a lesion.
Osteomyelitis: An inflammatory disease of bone caused usually by infection with streptococcus or staphylococcus.
Osteoporosis: Loss of calcium and other substances from bones, causing bones to become weak and prone to fractures.
