Achilles tendonitis is an inflammation of the Achilles tendon, which attaches the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). Pain can be felt on the back of the heel at the attachment of the tendon, along the length of the tendon, or at the base of the calf where the tendon attaches to the muscle. Swelling is not always present with this injury, but it may occur in severe cases.
Tendinitis can result from an injury or over-use. Improper stretching prior to exertion or incorrect form during physical activity can also contribute to the development of tendinitis. Some people, including those with ?flat feet,? tight tendons or arthritis, are particularly prone to tendinitis.
The Achilles tendon is a strong muscle and is not usually damaged by one specific injury. Tendinitis develops from repetitive stress, sudden increase or intensity of exercise activity, tight calf muscles, or a bone spur that rubs against the tendon. Common signs and symptoms of Achilles Tendinitis include, gradual onset of pain at the back of the ankle which may develop in several days up to several months to become bothersome. Heel pain during physical activities which may diminish after warming up in early stages, or become a constant problem if the problem becomes chronic. Stiffness at the back of the ankle in the morning. During inactivity, pain eases. Swelling or thickening of the Achilles tendon. Painful sensation if the Achilles tendon is palpated. If a pop is heard suddenly, then there is an increased chance that the Achilles tendon has been torn and immediate medical attention is needed.
On examination, an inflamed or partially torn Achilles tendon is tender when squeezed between the fingers. Complete tears are differentiated by sudden, severe pain and inability to walk on the extremity. A palpable defect along the course of the tendon. A positive Thompson test (while the patient lies prone on the examination table, the examiner squeezes the calf muscle; this maneuver by the examiner does not cause the normally expected plantar flexion of the foot).
The aim of the treatment is to reduce strain on the tendon and reduce inflammation. Strain may be reduced by, avoiding or severely limiting activities that may aggravate the condition, such as running, using shoe inserts (orthoses) to take pressure off the tendon as it heals. In cases of flat or hyperpronated feet, your doctor or podiatrist may recommend long-term use of orthoses. I8nflammation may be reduced by, applying icepacks for 20 minutes per hour during the acute stage, taking non-steroidal anti-inflammatory drugs, placing the foot in a cast or restrictive ankle-boot to minimise movement and give the tendon time to heal. This may be recommended in severe cases and used for about eight weeks. Occasionally depot (slowly absorbed) steroid injections may be tried, particularly for peri-tendinitis, but great care needs to be taken to avoid injecting into the tendon. This should only be done by a specialist doctor. You may also be given specific exercises to gently stretch the calf muscles once the acute stage of inflammation has settled down. Your doctor or physiotherapist will recommend these exercises when you are on the road to recovery. Recovery is often slow and will depend on the severity of the condition and how carefully you follow the treatment and care instructions you are given.
Most people will improve with simple measures or physiotherapy. A small number continue to have major problems which interfere with their lifestyle. In this situation an operation may be considered. If an operation is being considered, the surgeon will interview you and examine you again and may want you to have further treatment before making a decision about an operation. Before undergoing Achilles tendonitis surgery, London based patients, and those who can travel, will be advised to undergo a scan, which will reveal whether there is a problem in the tendon which can be corrected by surgery. Patients will also have the opportunity to ask any questions and raise any concerns that they may have, so that they can proceed with the treatment with peace of mind.
The following measures can significantly reduce the risk of developing Achilles tendonitis. Adequately stretch and warm up prior to exercise. Warm down and stretch after exercise. Choose footwear carefully and use footwear appropriate to the sport being undertaken. Use orthotic devices in footwear to correctly support the foot. Exercise within fitness levels and follow a sensible exercise programme. Develop strong, flexible calf muscles.
