Osteoarthritis: Common Sites

Osteoarthritis (OA) is sometimes called degenerative joint disease or wear-and-tear arthritis. It's the most common type of arthritis. In OA, the cartilage wears away. Cartilage covers the ends of bones and acts as a cushion. If enough cartilage wears away, bone rubs against bone. The joint changes in OA cause pain, stiffness, and trouble moving. OA may occur in any joint. Some joint that are commonly affected are the spin, neck,  hips, knees, fingers and toes.

Joints between small bones in the neck may wear out. Pain may travel to the shoulder or the base of the skull.

Lumbar Spine

Bony spurs may form on the joints between the vertebrae (spinal bones). And disks (cushions of cartilage between vertebrae) may wear down. Pain may affect the lower back or leg.

Hip

Cartilage damage can occur in the large “ball and socket” joint that connects the pelvis and thighbone. Pain may travel to the groin, buttocks, or knee.

Knee

The cartilage in the knee joint may wear down. Weakness or instability in the knee joint may make walking or climbing stairs difficult.

Fingers

Finger joints may become enlarged and knobby. Grasping objects may be hard, especially if the joint at the base of the thumb is affected.

Toes

Toes may be affected. Arthritis may cause a bunion, a bump at the base of the big toe. Standing or walking may be painful.
