Heel spurs, pointed, bony outgrowths of the heel, are caused by localized soft tissue inflammation and can be located at the back of the heel or under the heel, beneath the sole of the foot. Plantar fascitis is associated with inflammation caused by heel spurs on the soles of the feet. Both conditions are treated with ice application and anti-inflammatory medications. Orthotics may also provide some relief.
One common cause of heel spurs and related injuries is due to abnormal mechanics and movement of the foot, also referred to as pronation. Abnormal gait, which is the way our feet hit the ground as we walk, also stresses the tissue of the foot, leading to conditions such as plantar fasciitis and heel spurs. Pronation can cause the foot to become unstable during movement, affecting the gait and leading to damage. A sudden increase in weight can also influence the development of a painful heel spur.
Heel spur is characterised by a sharp pain under the heel when getting out of bed in the morning or getting up after sitting for a period of time. Walking around for a while often helps reduce the pain, turning it into a dull ache. However, sports, running or walking long distance makes the condition worse. In some cases swelling around the heel maybe present.
A thorough history and physical exam is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
Initially, treatment usually consists of a combination of ice therapy, stretching exercises to improve flexibility (especially in the mornings), anti-inflammatory medications, and physical therapy. Most patients will also need custom-molded orthotics to help control the motion in the foot and arch, which takes the strain off the plantar fascia. If the pain continues, a cortisone injection may be used to calm the severe swelling and pain. There may the need for a night splint to maintain a stretch in the plantar fascia throughout the night.
Surgery is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.
Heel spurs and plantar fasciitis can only be prevented by treating any underlying associated inflammatory disease.
