Retrocalcaneal bursitis is closely related to Haglund?s Deformity (or ?pump bumps?). If you have a bony enlargement on the back of the heel that rubs the Achilles tendon, it can cause the formation
of a bursa (small fluid filled sack). It usually happens in athletes as shoes rub against the heel. The bursa can aggravated by the stitching of a heel counter in the shoe as well. It can make
wearing shoes and exercising difficult. Another term used for this condition is ?pump bump? because it can frequently occur with wearing high heels as well. ?Retro-" means behind and ?calcaneus?
means heel bone. So this is precisely where the bursitis (inflammation of the bursa) develops. Once it begins and you develop bursitis between the heel bone and the Achilles tendon, it can become
even more painful. When most people first notice retrocalcaneal bursitis, it is because the skin, bursa and other soft tissues at the back of the heel gets irritated as the knot of bone rubs against
the heel counter in shoes. The back of the shoes create friction and pressure that aggravate the bony enlargement and pinches the bursa while you walk.
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.
Symptoms of bursitis usually occur after rest and relaxation. Upon activity there is usually more intense pain in the area of the bursa. The common areas to have a bursitis in the foot are in the
bottom of the heel, behind the heel near the attachment of the Achilles Tendon as well as along the side of a bunion. A bursa may also form in multiple areas especially along the metatarsal heads, or
"ball" of your foot. You may actually feel the sac like fluid when rubbing the area of pain.
Your doctor will examine you, including an evaluation of your gait, while you are barefoot, your doctor will ask you to stand still and to walk in order to evaluate how your foot moves as you walk.
An examination of your feet. Your doctor may compare your feet for any differences between them. Then your doctor may examine your painful foot for signs of tenderness, swelling, discoloration,
muscle weakness and decreased range of motion. A neurological examination. The nerves and muscles may be evaluated by checking strength, sensation and reflexes. In addition to examining you, your
health care professional may want to examine your shoes. Signs of excessive wear in certain parts of a shoe can provide valuable clues to problems in the way you walk and poor bone alignment.
Depending on the results of your physical examination, you may need foot X-rays or other diagnostic tests.
Non Surgical Treatment
The most important factor in healing bursitis is resting your foot and ankle. This can be difficult when you have to carry on with daily activities, but resting and elevating your foot whenever you
can is recommended. During your recovery you will probably have to modify or avoid the activities that stress your bursa until your pain and inflammation settle.
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.
