The heel bone is the largest bone in the foot and absorbs the most shock and pressure. A heel spur develops as an abnormal growth of the heel bone. Most commonly, calcium deposits form when the plantar fascia pulls away from the heel area, causing a bony protrusion, or heel spur to develop. While bone spurs can develop in other locations such as the rear of the heel bone, this is the most common location for development. The plantar fascia is a broad band of fibrous tissue located along the bottom surface of the foot that runs from the heel to the forefoot. Heel spurs can cause extreme pain in the rearfoot, especially while standing or walking.
Faulty foot structures such as abnormal growths, different leg lengths, and unhealed injuries and haveinf flat feet or high arches. Muscle imbalances tight, weak or shortened muscles in your foot, plantar fascia, ankle, calf and hamstring. Over pronation can cause imbalance in foot mechanics which puts excess pressure on the plantar fascia. Poor biomechanics affect the way your foot hits the ground. If you overpronate (feet roll inward) you tend to have flat feet (pes planus), which increases stress on the heel bone. Regular shoes or high heels that are too tight or don't support your heel or arch affect the distribution of your body weight on your foot. Health conditions such as obesity, inflammatory diseases (rheumatoid arthritis, ankylosing spondylitis), bursitis, neuroma (nerve growths), gout, diabetes, Haglund's deformity, and Achilles tendinitis can also instigate the problem. Running or jogging on hard surfaces, repetative striking of the heel bone.
Symptoms of heel spur syndrome often include pain early in the morning or after rest, as you take the first few steps. It may also include severe pain after standing or walking long hours, especially on hard cement floors. Usually more pain exist while wearing a very flat soled shoe. A higher heel may actually relieve the pain as an arch is created. The pain is usually sharp, but can also be a dull ache. The pain may only be at the bottom of the heel, or may also travel along the arch of the foot.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
Non Surgical Treatment
By reducing excessive motion and controlling and supporting the foot during physical activities an orthotic can help to limit how far the plantar fascia is pulled or torn away from the heel. A Heel Spur pad can be offered- which is a pad designed to take pressure off the spur. If the problem persists, consult your foot doctor.
Heel spur surgery should only be considered after less invasive treatment methods have been explored and ruled insufficient. The traditional surgical approach to treating heel spurs requires a scalpel cut to the bottom of the food which allows the surgeon to access the bone spur. Endoscopic plantar fasciotomies (EPF) involve one or two small incisions in the foot which allow the surgeon to access and operate on the bone spur endoscopically. Taking a surgical approach to heel spur treatment is a topic to explore with a foot and ankle specialist.
