The following are common causes of bone spurs on the foot: First, if the heel spur is a bone spur, it is mostly due to repeated pulling of the metatarsal fascia. If the patient has a low arch or flat feet, excessive stress on the metatarsal fascia during prolonged walking and pulling on the heel nodal stop can cause local osteophytes and form bone spurs. The direction of the spur is consistent with the direction of travel of the metatarsal fascia, and the patient will have painful symptoms in the heel. Second, excessive weight-bearing on the joint. Excessive weight-bearing or force on the toe joint can lead to degenerative changes in the joint and the formation of joint inflammation, and there will be obvious osteophytes at the edges of the joint with bone spur formation. Patients usually have symptoms such as joint space narrowing, joint deformation, limited joint movement, etc. Severe cases may have difficulty walking.
