Osteophyte, commonly known as bone spur, is a tiny pointed outgrowth of bone. The condition can be caused due to tendonitis or degenerative arthritis. The condition may appear in areas where a cartilage or tendon is injured. Bone spurs can cause symptoms at times. But it will not have any symptom at all times. When there are symptoms, the symptoms may depend on the location of the spur. When the condition irritates the adjoining tissue, it can cause pain, tenderness, numbness or weakness. The condition is treated only when it causes symptoms. Treatment will be directed towards reducing the inflammation associated with the condition. Bone spurs mostly appear on the knee, shoulder, neck, big toe or finger, foot or heel, and lower back.
