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.
Although rare, bursitis also may be caused by an infection, known as septic bursitis. This is a serious medical condition that requires antibiotics to treat the infection and prevent its spread to other points in the body or the bloodstream. Septic bursitis may cause the back of the ankle to become red or hot. The person may also get the chills or fever and may feel sick and tired. Typically this type of bursitis would be suspected if there has been any history of an open wound in the area, such as a blister.
Unlike Achilles tendinitis, which tends to manifest itself slightly higher on the lower leg, Achilles tendon bursitis usually creates pain and irritation at the back of the heel. Possible signs of bursitis of the Achilles tendon include difficulty to rise on toes. Standing on your toes or wearing high heels may increase the heel pain. Inflammation and tenderness. The skin around your heel can become swollen and warm to the touch. Redness may be visible. Pain in the heel. Pain tends to become more prominent when walking, running, or touching the inflamed area. Stiffness. The back of your ankle may feel a little stiff due to the swelling of the bursa.
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
Treatments should involve decreasing swelling, relieving pain and stress on the Achilles, correcting any biomechanical dysfunction (over-pronation or flat feet), treating scar tissue, and then restoring strength and movement. If you are performing an activity that could cause further trauma to the bursa, it is recommended that you protect the area with padding and/or proper footwear to prevent further irritation or damage.
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
Protect that part of the body that may be most vulnerable, If you have to kneel a lot, get some knee pads. Elbow braces can protect tennis and golf players. If you are an athlete or avid walker, invest in some good walking or running shoes. When doing repetitive tasks have breaks. Apart from taking regular breaks, try varying your movements so that you are using different parts of your body. Warm up before exercise. Before any type of vigorous exercise you should warm up for at least 5 to 10 minutes. The warm up could include walking at a good speed, slow jogging, or a cycling machine. Strong muscles add extra protection to the area. If you strengthen the muscles in the area where you had bursitis (after you are better), especially the area around the joint, you will have extra protection from injury. Make sure you do this well after your bursitis has gone completely.
