Achilles tendinitis is an irritation/inflammation in the achilles tendon, which attaches to the back of the heel. It is often a result of overuse and occurs frequently in runners who have altered their training suddenly, either with regard to duration or intensity. This injury is also prevalent in middle-aged people who are active.
Some of the causes of Achilles tendonitis include, overuse injury – this occurs when the Achilles tendon is stressed until it develops small tears. Runners seem to be the most susceptible. People who play sports that involve jumping, such as basketball, are also at increased risk. Arthritis – Achilles tendonitis can be a part of generalised inflammatory arthritis, such as ankylosing spondylitis or psoriatic arthritis. In these conditions, both tendons can be affected. Foot problems – some people with flat feet or hyperpronated feet (feet that turn inward while walking) are prone to Achilles tendonitis. The flattened arch pulls on calf muscles and keeps the Achilles tendon under tight strain. This constant mechanical stress on the heel and tendon can cause inflammation, pain and swelling of the tendon. Being overweight can make the problem worse. Footwear – wearing shoes with minimal support while walking or running can increase the risk, as can wearing high heels. Overweight and obesity – being overweight places more strain on many parts of the body, including the Achilles tendon. Quinolone antibiotics – can in some instances be associated with inflammatory tenosynovitis and, if present, will often be bilateral (both Achilles), coming on soon after exposure to the drug.
People with Achilles tendinitis may experience pain during and after exercising. Running and jumping activities become painful and difficult. Symptoms include stiffness and pain in the back of the ankle when pushing off the ball of the foot. For patients with chronic tendinitis (longer than six weeks), x-rays may reveal calcification (hardening of the tissue) in the tendon. Chronic tendinitis can result in a breakdown of the tendon, or tendinosis, which weakens the tendon and may cause a rupture.
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Imaging studies. Plain radiography: Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography: Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst; in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI): MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis.
Ask your Pharmacist for advice. 1) Your Pharmacy stocks a range of cold packs which may be applied to the area to decrease inflammation. 2) Ask your Pharmacist about a temporary heel raise or pad which can be inserted into footwear to decrease the force absorbed by the tendon when the feet land heavily on the ground. 3) Gently massaging a heat-producing liniment into the calf can help to relieve tension in the muscle which may relieve the symptoms of Achilles Tendinitis. Ask your Pharmacist to recommend the most appropriate type. 4) Gels, sprays or creams which help to reduce inflammation are available and may be applied to the injured area. Ask your Pharmacist for advice. 5) Your Pharmacist can advise you on analgesic, anti-inflammatory medications such as Aspirin which may be of assistance. Aspirin should be avoided in children under the age of 12 and those aged 12 to 15 who have a fever. 6) Strapping the ankle can help restrict movement and minimise further injury. Your Pharmacist stocks a range of athletic strapping tape and ankle guards which may assist your injury.
If non-surgical treatment fails to cure the condition then surgery can be considered. This is more likely to be the case if the pain has been present for six months or more. The nature of the surgery depends if you have insertional, or non-insertional disease. In non-insertional tendonosis the damaged tendon is thinned and cleaned. The damage is then repaired. If there is extensive damage one of the tendons which moves your big toe (the flexor hallucis longus) may be used to reinforce the damaged Achilles tendon. In insertional tendonosis there is often rubbing of the tendon by a prominent part of the heel bone. This bone is removed. In removing the bone the attachment of the tendon to the bone may be weakened. In these cases the attachment of the tendon to the bone may need to be reinforced with sutures and bone anchors.
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.
