Infracalcaneal bursitis can significantly affect a person?s quality of life and his or her ability to perform activities of daily living, due to pain and impaired gait. This foot health problem may
be diagnosed in several ways, including by palpation, or light pressure applied to the affected area by a healthcare practitioner. If the heel pain has existed for a long time, X-ray imaging studies
may reveal localized calcification in the infracalcaneal bursa, though this is not always the case. MRI images are sometimes used as a diagnostic tool for this health problem, though MRI studies are
considered unnecessary for diagnosis in many cases.
Inflammation of the bursa causes synovial cells to multiply and thereby increases collagen formation and fluid production. A more permeable capillary membrane allows entrance of high protein fluid.
The bursal lining may be replaced by granulation tissue followed by fibrous tissue. The bursa becomes filled with fluid, which is often rich in fibrin, and the fluid can become hemorrhagic. One study
suggests that this process may be mediated by cytokines, metalloproteases, and cyclooxygenases.
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.
On physical examination, patients have tenderness at the site of the inflamed bursa. If the bursa is superficial, physical examination findings are significant for localized tenderness, warmth,
edema, and erythema of the skin. Reduced active range of motion with preserved passive range of motion is suggestive of bursitis, but the differential diagnosis includes tendinitis and muscle injury.
A decrease in both active and passive range of motion is more suggestive of other musculoskeletal disorders. In patients with chronic bursitis, the affected limb may show disuse atrophy and weakness.
Tendons may also be weakened and tender.
Non Surgical Treatment
You should rest from all activities that cause pain or limping. Use crutches/cane until you can walk without pain or limping. Ice. Place a plastic bag with ice on the foot for 15-20 minutes, 3-5
times a day for the first 24-72 hours. Leave the ice off at least 1 1/2 hours between applications. Compression. Lightly wrap an elastic bandage from the toes to mid calf, using even pressure. Wear
this until swelling decreases. Loosen the wrap if your toes start to turn blue or feel cold. Elevate. Make sure to elevate the ankle above heart level. To improve symptoms of plantar calcaneal
bursitis after the acute phasetry the baked bean tin stretch, using a baked bean tin roll the foot backwards and forwards. 2 minutes in the morning before putting the foot to the floor. 5-10 minutes
every evening. Contrast foot baths. 10 minutes warm water. 10 minutes cool water morning and evening (morning may be missed if time is restricted). Stretches. Start with 10 stretches per day, holding
the stretch for 30 seconds, then relax and then repeat. Continue this stretch daily until you can no longer feel it pulling on the heel, then progress to stretch. Do 10 per day holding for 30 seconds
per stretch. When you can no longer feel it pulling on the heel proceed to stretches. Do 10 per day holding for 30 seconds on every stretch.
Surgery. Though rare, particularly challenging cases of retrocalcaneal bursitis might warrant a bursectomy, in which the troublesome bursa is removed from the back of the ankle. Surgery can be
effective, but operating on this boney area can cause complications, such as trouble with skin healing at the incision site. In addition to removing the bursa, a doctor may use the surgery to treat
another condition associated with the retrocalcaneal bursitis. For example, a surgeon may remove a sliver of bone from the back of the heel to alter foot mechanics and reduce future friction. Any
bone spurs located where the Achilles attaches to the heel may also be removed. Regardless of the conservative treatment that is provided, it is important to wait until all pain and swelling around
the back of the heel is gone before resuming activities. This may take several weeks. Once symptoms are gone, a patient may make a gradual return to his or her activity level before their bursitis
symptoms began. Returning to activities that cause friction or stress on the bursa before it is healed will likely cause bursitis symptoms to flare up again.
