Retrocalcaneal bursitis is the inflammation of the fluid-filled sac (bursa) at the back of the heel bone (calcaneus). The retrocalcaneal bursa is located between the Achilles tendon and the heel bone and is designed to reduce friction between the Achilles tendon and the heel bone. During contraction of the calf muscle, tension is generated through the Achilles tendon and it rubs against the retrocalcaneal bursa. When there is excessive friction due to repetitive rubbing of the tendon against the bursa or high impact force translating through the Achilles tendon, irritation and inflammation of the bursa may occur. The inflammation can also be aggravated by pressure, such as when athletes wear tight-fitting shoes. This condition is often mistaken for Achilles tendinitis but it can also occur in conjunction with Achilles tendinitis.
Bursitis may be the result of a direct injury to the heel, such as during a car accident, sport-related accident, or fall that causes a forceful impact or abnormal twisting of the foot. It can also occur due to repetitive use, misuse, or overuse, such as seen in athletic over-training. Excessive pressure over the subcutaneous calcaneal bursa, such from wearing shoes that are tight or fit poorly, can also be a causative factor. Septic bursitis occurs secondary to an infection. The infection may occasionally be systemic, but is most often a localized infection from a subcutaneous heel wound that leaks into the underlying bursa. Other risk factors include any of the following, existing Achilles tendinitis, existing Haglund's deformity, the natural degenerative processes of aging, improper stretching prior to exercise, anatomical differences in the lower extremities that impacts gait, having deformed joints.
Bursitis involving the heel causes pain in the middle of the undersurface of the heel that worsens with prolonged standing and pain at the back of the heel that worsens if you bend your foot up or down.
A good clinical practise includes evaluation of the tendon, bursa and calcaneum by, careful history, inspection of the region for bony prominence and local swelling as well as palpation of the area of maximal tenderness. Biomechanical abnormalities, joint stiffness and proximal soft tissue tightening can exacerbate an anatomical predisposition to retrocalcaneal bursitis, they warrant correction when present.
Non Surgical Treatment
Other than rest, once the diagnosis of heel bursitis (Achilles bursitis, Retrocalcaneal bursitis) has been confirmed then your treating doctor will either generally recommend one or more of the following, Pain killers. Non steroid anti-inflammatory medication. A cortisone steroid injection. Surgery in extreme cases. Whilst the above may be beneficial for some people, others unfortunately will not be suitable for such heel bursitis treatments. This may be for several reasons such as having already tried these medications with little to no benefit or not being able to take these type of medications due to pre-existing medical conditions or alternatively some individuals may just prefer to avoid painful injections or strong medications and instead use a natural heel bursitis treatment.
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, as well as good flexibility and strength around the ankle to help prevent this condition. Proper stretching of the Achilles tendon helps prevent injury.
