The Treatment Of Achilles Tendinitis
Overview
Do you experience dull pain near the back of your heel or in the back of your leg after your regular run or after playing your favourite sport? When you ramp up your exercise is the pain more severe or prolonged? If so, you may have Achilles tendinitis. The Achilles tendon is the thick, strong, springy band of tissue that connects the muscles from the middle of your calf to your heel bone. You use your Achilles tendon when you walk, run or jump. Achilles tendinitis occurs when the Achilles tendon is repeatedly strained. The Achilles tendon becomes less flexible, weaker and more prone to injury as we age. Middle-aged weekend warriors and runners who suddenly intensify their training often suffer from Achilles tendinitis.
Causes
Achilles tendinitis usually results from overuse and not a specific injury or trauma. When the body is subject to repetitive stress, the Achilles tendon is more prone to become inflamed. Other factors may cause Achilles tendinitis, such as, Sudden increase in physical activity, which can be related to distance, speed or hills, without giving yourself adequate time to adjust to the heightened activity. With running up hills, the Achilles tendon has to stretch more for each stride, which creates rapid fatigue. Inadequate footwear or training surface. High heels may cause a problem, because the Achilles tendon and calf muscles are shortened. While exercising in flat, athletic shoes, the tendon is then stretched beyond its normal range, putting abnormal strain on the tendon. Tight calf muscles which gives the foot a decreased range of motion. The strained calf muscles may also put extra strain on the Achilles tendon. Bone spur where the Achilles tendon attaches to the heel bone, aggravating the tendon and causing pain.
Symptoms
Symptoms vary because you can injure various areas of the muscle-tendon complex. The pain may be an acute or chronic sharp, stabbing, piercing, shooting, burning or aching. It is often most noticeable immediately after getting out of bed in the morning, or after periods of inactivity, like sitting down for lunch. After a couple minutes of walking around, it will often then settle down somewhat, before becoming symptomatic again after excessive time standing or walking. But regardless of how the pain is perceived, Achilles tendon pain should not be left untreated due to the danger that the tendon can become weak, frayed, thickened, and eventually it may rupture.
Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
Nonsurgical Treatment
Massage therapy improves blood flow to the muscles and tissues of the affected area while increasing range of motion and can prevent recurring injury. The healing process can be quickened using ultrasound heat therapy to improve blood flow to the affected area. Wearing a night brace keeps the leg flexed, preventing stiffening of the tendon, which would impair healing. Stretching exercises increase flexibility and allow the tendon to heal without shortening, a deformity resulting in chronic pain. Persistent Achilles pain may warrant the use of a cast or walking boot to be worn for 4-6 weeks stabilizing the tendon so it can heal. After removal of the cast or boot, physical therapy will be ordered to increase functionality of the affected limb. To reduce chronic inflammation of the tendon, corticosteroid injections may be prescribed. It?s important to note that this corticosteroid treatment increases the risk of tendon rupture. Ultrasound imaging may be used by the physician administering the steroid injection, in order to help visualize the affected area. When all other therapies have failed to or tendon rupture occurs, surgical intervention and repair of the muscles and tendons is the last treatment option.
Surgical Treatment
Surgery is an option of last resort. However, if friction between the tendon and its covering sheath makes the sheath thick and fibrous, surgery to remove the fibrous tissue and repair any tears may be the best treatment option.
Prevention
Maintaining strength and flexibility in the muscles of the calf will help reduce the risk of tendinitis. Overusing a weak or tight Achilles tendon makes you more likely to develop tendinitis.
