Between the heel bone and the plantar fascia is a small fluid filled sac that is called the plantar (bottom of) calcaneal (heel bone) bursa. The plantar calcaneal bursa?s job is to allow the plantar fascia to glide easily over the heel bone without irritation. If this becomes inflamed and irritated a plantar calcaneal bursitis occurs which can be extremely painful and disabling forcing the athlete to stop training.
The causes and risk factors of retrocalcaneal bursitis are listed below. Identifying the underlying reason the bursa is inflamed will help set a course for treatment. Repetitive use of the ankle. Retrocalcaneal bursitis is often caused by frequent “mini-traumas.” These mini-traumas are often due to excessive walking, jumping, or running. Running uphill, which causes the foot to flex considerably, can be especially irritating to the retrocalcaneal bursae. People who suddenly intensify their exercise programs without adequate stretching and muscle conditioning may get retrocalcaneal bursitis. In general, it is often associated with over use of the Achilles attachment, the area where the Achilles tendon fibers attach to the heel.
A dull ache under the heel when not weight bearing. Sometimes severe pain when walking. Pain can increase after resting (sleeping or sitting) then standing and placing pressure on the area again. Throbbing under the heel. Swelling may be identified as a discernible lump under the heel. This is the swollen calcaneal bursa itself. Tingling under the heel as swelling affect the plantar nerves. Pains shooting into the foot or up the leg.
Bursitis is usually diagnosed after a careful physical examination and a full review of your medical history. If you garden and spend a lot of time on your knees, or if you have rheumatoid arthritis, tell your doctor, this information can be very helpful. During the physical exam, he or she will press on different spots around the joint that hurts. The goal is to locate the specific bursa that is causing the problem. The doctor will also test your range of motion in the affected joint. Other tests usually aren?t required to diagnose bursitis, but your doctor may suggest an MRI, X-ray or ultrasound to rule out other potential causes of pain.
Non Surgical Treatment
Podiatric Care may include using anti-inflammatory oral medications or an injection of medication and local anesthetic to reduce the swelling in the bursa. An injection may be used for both diagnosis and for treatment. When you go to your doctor, x-rays are usually required to evaluate the structure of your foot and ankle to ensure no other problems exist in this area. They may advise you on different shoewear or prescribe a custom made orthotic to try and control the foot structure especially if you have excessive pronation. Sometimes patients are sent to Physical Therapy for treatment as well. To aid in relief of pressure points, some simple padding techniques can be utilized. Most all patients respond to these conservative measures once the area of irritation is removed.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
Continue to wear your orthotics for work and exercise to provide stability and restore foot function. Select suitable shoes for work and physical activity that provide stability for the heel. Regular stretching of the calf muscle can prevent heel bursitis. Do not suddenly increase activity amount without appropriate conditioning.
