The foot only contains one naturally occurring bursal sac between the Achilles tendon and the heel bone, which protects the Achilles from the pressure against the heel bone during ambulation. However, shoes may put pressure on this bursa. The bursa might also incur trauma from walking on hard ground. And, though they are not naturally occurring, bursa sacs can also form, and become inflamed, in other parts of the foot, including the bottom of the heel, and the metatarsal plate, the outside of the foot below the fifth toe, and so on.
There are several factors which can predispose patients to developing this condition. These need to be assessed and corrected with direction from a physiotherapist and may include poor foot biomechanics (particularly flat feet), inappropriate footwear (e.g. excessively tight fitting shoes), muscle weakness (particularly the calf, quadriceps and gluteals), muscle tightness (particularly the calf), joint stiffness (particularly the ankle, subtalar joint or foot), bony anomalies of the heel bone, inappropriate or excessive training or activity, inadequate recovery periods from sport or activity, inadequate warm up, inadequate rehabilitation following a previous Achilles injury, change in training conditions or surfaces, inappropriate running technique, inadequate fitness, poor pelvic and core stability, poor proprioception or balance, being overweight.
Medical experts strongly recommend that you consult a doctor if you have any of the symptoms below. Disabling joint pain that prevents you from doing your daily activities. Pain that lasts for more than two weeks. Excessive swelling, redness, bruising or a rash around the painful joint. Sharp or shooting pain, especially when you exercise or do something more strenuous. A fever. Any of the above could be a sign of infection, a condition such as arthritis or a more serious injury such as a tendon tear that may require medical attention.
A thorough subjective and objective examination from a physiotherapist may be all that is necessary to diagnose a retrocalcaneal bursitis. Diagnosis may be confirmed with an ultrasound investigation, MRI or CT scan.
Non Surgical Treatment
Gradually progressive stretching of the Achilles tendon may help to relieve impingement on the subtendinous calcaneal bursa. Stretching of the Achilles tendon can be performed by having the patient place the affected foot flat on the floor and lean forward toward the wall until a gentle stretch is felt in the ipsilateral Achilles tendon. The stretch is maintained for 20-60 seconds and then is relaxed. Achilles stretch 1. The patient stands with the affected foot flat on the floor and leans forward toward the wall until a gentle stretch is felt in the ipsilateral Achilles tendon. The stretch is maintained for 20-60 seconds and then is relaxed. Achilles stretch 2. This stretch, which is somewhat more advanced than that shown in Images 1-2, isolates the Achilles tendon. It is held for at least 20-30 seconds and then is relaxed. To maximize the benefit of the stretching program, the patient should repeat the exercise for multiple stretches per set, multiple times per day. Ballistic (ie, abrupt, jerking) stretches should be avoided in order to prevent clinical exacerbation. The patient should be instructed to ice the posterior heel and ankle in order to reduce inflammation and pain. Icing can be performed for 15-20 minutes at a time, several times a day, during the acute period, which may last for several days. Some clinicians also advocate the use of contrast baths, ultrasound or phonophoresis, iontophoresis, or electrical stimulation for treatment of calcaneal bursitis. If the patient’s activity level needs to be decreased as a result of this condition, alternative means of maintaining strength and cardiovascular fitness (eg, swimming, water aerobics) should be suggested.
To prevent bursitis of the heel in the first place, always keep proper form during exercise. In addition, don?t jump into exercises that are too intense without building up to them. Strengthen and flex your ankle.
