Retrocalcaneal bursitis is the painful inflammation and swelling of the retrocalcaneal bursa that is situated between the calcaneus (heel bone) and the Achilles tendon. A bursa is a small fluid filled sac that forms around joints in areas where there is a lot of friction between muscles, tendons and outcrops of bone. The bursae position themselves in between the tendon or muscle and the bone, buffering any friction from movement. To picture a bursa imagine it as a very small water filled balloon that sits in places where things rub against each other, such as in between a tendon and a bone, to provide a soft smooth cushion for the tendon to pass over painlessly. The covering of the bursa also acts as a lubricant and aids the tendon?s movement. It is estimated that there is over 150 bursae in your body which protect the joint and tendons from wear. They are all very small and unnoticeable until they become swollen and painful with bursitis.
As ligaments and tendons stretch and tear, blood from ruptured blood vessels becomes trapped in the local tissues. As the trapped blood clots up, it sticks the tissues together creating adhesions. Adhesions cause pain, inflammation and restricted movement because the layers of tissue that used to slide smoothly across one another now adhere and snap which interferes with normal functioning. It is essential to break up clotted blood as quickly as possible to prevent adhesions and scar tissue from forming.
Posterior heel pain is the chief complaint in individuals with calcaneal bursitis. Patients may report limping caused by the posterior heel pain. Some individuals may also report an obvious swelling (eg, a pump bump, a term that presumably comes from the swelling's association with high-heeled shoes or pumps). The condition may be unilateral or bilateral. Symptoms are often worse when the patient first begins an activity after rest.
If heel pain has not responded to home treatment, X-rays may be ordered. These images can show deformities of the heel bone and bone spurs that have developed at the attachment of the Achilles. If there is swelling and/or pain that is slightly higher and within the Achilles tendon itself, an MRI may be ordered to determine if the tendon is simply inflamed or if there is a chronic tear on the tendon. Aspiration and lab tests. If a septic bursitis is highly suspected, a doctor may perform an aspiration, removing fluid from the bursa with a needle and syringe. In addition to relieving pressure and making the patient more comfortable, it provides a fluid sample that can be tested for infection.
Non Surgical Treatment
Orthotics may assist heel bursitis by providing stability to the heel, reduce any foot functioning abnormalities and provide extra support for the feet. The orthotic achieves this by maintaining correct foot posture, therefore facilitating normal functioning of the Achilles tendon. Icing the back of the heel post activity for temporary relief. Non-steroidal anti-inflammatory medication such as ibuprofen can reduce inflammation of the bursa. Stretching of the calf muscle may reduce the pulling on the heel by the Achilles tendon. Shoes that have an elevated heel may reduce pulling on the heel from the Achilles tendon. Resting the painful heel may reduce inflammation and pain. Surgical removal of the painful bursa is a last resort treatment when all other treatments have failed.
Only if non-surgical attempts at treatment fail, will it make sense to consider surgery. Surgery for retrocalcanel bursitis can include many different procedures. Some of these include removal of the bursa, removing any excess bone at the back of the heel (calcaneal exostectomy), and occasionally detachment and re-attachment of the Achilles tendon. If the foot structure and shape of the heel bone is a primary cause of the bursitis, surgery to re-align the heel bone (calcaneal osteotomy) may be considered. Regardless of which exact surgery is planned, the goal is always to decrease pain and correct the deformity. The idea is to get you back to the activities that you really enjoy. Your foot and ankle surgeon will determine the exact surgical procedure that is most likely to correct the problem in your case. But if you have to have surgery, you can work together to develop a plan that will help assure success.
Maintain proper form when exercising, good flexibility, and strength around the ankle to help prevent this condition from arising. Proper stretching of the achilles tendon helps prevent injury.
