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.
Bursitis has many causes, including autoimmune disorders, crystal deposition (gout and pseudogout), infectious diseases, traumatic events, and hemorrhagic disorders, as well as being secondary to overuse. Repetitive injury within the bursa results in local vasodilatation and increased vascular permeability, which stimulate the inflammatory cascade.
The main symptom of heel bursitis is pain. You may experience pain in your heel when you walk or run. There may also be pain if the area is touched or if you stand on your tiptoes. In addition to pain, the area may appear red and warm, which are both signs of inflammation. Even if you have these symptoms, only a doctor can determine if you have bursitis of the heel. Your doctor will use these symptoms along with a general exam to determine if you are suffering from bursitis of the heel.
During the physical examination of a patient with calcaneal bursitis, the physician should keep the following considerations in mind. Swelling and redness of the posterior heel (the pump bump) may be clearly apparent. The inflamed area, which may be slightly warm to the touch, is generally tender to palpation. Careful examination can help the clinician to distinguish whether the inflammation is posterior to the Achilles tendon (within the subcutaneous calcaneal bursa) or anterior to the tendon (within the subtendinous calcaneal bursa). Differentiating Achilles tendinitis/tendinosis from bursitis may be impossible. At times, the 2 conditions co-exist. Isolated subtendinous calcaneal bursitis is characterized by tenderness that is best isolated by palpating just anterior to the medial and lateral edges of the distal Achilles tendon. Conversely, insertional Achilles tendinitis is notable for tenderness that is located slightly more distally, where the Achilles tendon inserts on the posterior calcaneus. A patient with plantar fasciitis has tenderness along the posterior aspect of the sole, but he/she should not have tenderness with palpation of the posterior heel or ankle. A patient with a complete avulsion or rupture of the Achilles tendon demonstrates a palpable defect in the tendon, weakness in plantarflexion, and a positive Thompson test on physical examination. During the Thompson test, the examiner squeezes the calf. The test is negative if this maneuver results in passive plantarflexion of the ankle, which would indicate that the Achilles tendon is at least partially intact.
Non Surgical Treatment
Despite appropriate physiotherapy management, some patients with retrocalcaneal bursitis do not improve adequately. When this occurs the treating physiotherapist or doctor can advise on the best course of management. This may include further investigations such as an ultrasound, X-Ray, MRI or CT scan, pharmaceutical intervention, corticosteroid and anaesthetic injection into the retrocalcaneal bursa, draining of the bursa, or review by a specialist or podiatrist who can advise on any treatment that may be appropriate to improve the condition.
People can lower the risk of bursitis by gradually strengthening and stretching the muscles around the joints and taking regular breaks from repetitive motion that might irritate bursae. Prolonged time resting on the elbows or kneeling should be avoided, if it cannot be avoided, wearing cushioned elbow and knee pads can help protect the bursae. Comfortable, supportive, low-heeled shoes can help prevent bursitis in the foot.
