Heel Spurs are deposits of calcium in the heel area of the foot that are the typically the result of tension, abrasion and/or inflammation in the plantar fascia attachment to the heel. The heel spur itself is said not to be painful. The pain likely arises from the inflammation of the plantar fascia. The plantar fascia encapsulates muscles in the sole of the foot. It supports the arch of the foot by acting as a bowstring to connect the ball of the foot to the heel. Common causes of heel spurs include excessive load on the foot from obesity or a sudden increase in weight, a sudden increase in walking or sports activities.
Heel spurs are exacerbated by an movements that stretch, twist or impact the plantar ligaments. Running, jumping, standing or walking on hard surfaces with unsupportive shoes, walking barefoot in sand are all activities that can activate heel spurs and plantar fasciitis. Obesity is another factor that increases stress to the plantar ligaments.
Symptoms may be similar to those of plantar fasciitis and include pain and tenderness at the base of the heel, pain on weight bearing and in severe cases difficulty walking. The main diagnosis of a heel spur is made by X-ray where a bony growth on the heel can be seen. A heel spur can occur without any symptoms at all and the athlete would never know they have the bony growth on the heel. Likewise, Plantar fasciitis can occur without the bone growth present.
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
Non Surgical Treatment
Heel pain may be associated with a heel spur, however the heel pain is usually due to plantar fasciitis, rather than a heel spur, so treatment is usually directed at the plantar fasciitis itself. Treatment usually involves application of ice to reduce pain and inflammation, special stretching exercises, and pain-relieving or anti-inflammatory medicines. Night splints or orthotics may be recommended. It may help to avoid the activities that aggravate pain, such as long walks and running. Surgery is very rarely recommended and only after other measures fail.
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.
You can help prevent heel spur symptoms from returning by wearing the proper shoes. Customized orthotics and insoles can help relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
