Concerning Achilles Tendonitis

Overview
Inflammation of the Achilles tendon.The Achilles is the large tendon connecting the two major calf muscles, gastrocnemius and soleus, to the back of the heel bone. Under too much stress, the tendon tightens and is forced to work too hard. This causes it to become inflamed (that is tendinitis), and, over time, can produce a covering of scar tissue, which is less flexible than the tendon. If the inflamed Achilles continues to be stressed, it can tear or rupture.

Causes
Achilles tendonitis is an overuse injury that is common especially to joggers and jumpers, due to the repetitive action and so may occur in other activities that requires the same repetitive action. Most tendon injuries are the result of gradual wear and tear to the tendon from overuse or ageing. Anyone can have a tendon injury, but people who make the same motions over and over in their jobs, sports, or daily activities are more likely to damage a tendon. A tendon injury can happen suddenly or little by little. You are more likely to have a sudden injury if the tendon has been weakened over time. Common causes of Achilles tendonitis include, over-training or unaccustomed use,?too much too soon?. Sudden change in training surface e.g. grass to bitumen. Flat (over-pronated) feet, High foot arch with tight Achilles tendon. tight hamstring (back of thigh) and calf muscles, toe walking (or constantly wearing high heels). Poorly supportive footwear, hill running. Poor eccentric strength.

Symptoms
Patients with this condition typically experience pain in the region of the heel and back of the ankle. In less severe cases, patients may only experience an ache or stiffness in the Achilles region that increases with rest (typically at night or first thing in the morning) following activities which place stress on the Achilles tendon. These activities typically include walking or running excessively (especially uphill or on uneven surfaces), jumping, hopping, performing heel raises or performing calf stretches. The pain associated with this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. Pain may also increase when performing a calf stretch or heel raise (i.e. rising up onto tip toes). In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with Achilles tendonitis may also experience swelling, tenderness on firmly touching the Achilles tendon, weakness and sometimes palpable thickening of the affected Achilles tendon when compared with the unaffected side.

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
Proper footwear with a strong and secure counter (the heel circumference) may help to encourage heeling of the tendon. A tendinitis will occasionally resolve on it?s own, with rest, ice, and gentle stretching. If symptoms persist for more than 2 weeks, consult your physician. Your physician may suggest physiotherapy and custom orthotics. Physiotherapy can suggest appropriate exercises and modalities to aid in the healing process. Custom orthotics can be very successful in treating the problem, as the original cause may be due to an improper alignment of the foot and heel. Re-aligning the foot to a neutral position may provide an optimal, biomechanically sound environment for healing to occur.



Surgical Treatment
In cases of severe, long-term Achilles tendonitis the sheath may become thick and fibrous. In these cases surgery may be recommended. Surgery aims to remove the fibrous tissue and repair any tears in the tendon. A cast or splint will be required after the operation and a recovery program including physiotherapy, specific exercises and a gradual return to activity will be planned.

Prevention
As with all injuries, prevention is your best defense especially with injuries that are as painful and inconvenient as Achilles tendonitis. Options for how to prevent Achilles tendonitis include, stretching- Stretching properly, starting slowly, and increasing gradually will be critical if you want to avoid Achilles tendonitis. To help maintain flexibility in the ankle joint, begin each day with a series of stretches and be certain to stretch prior to, and after, any exercise or excessive physical activity. Orthotics and Heel Support- Bio-mechanically engineered inserts and heel cups can be placed in your shoes to correct misalignments or bolster the support of your foot and are available without a prescription. The temporary heel padding that these provide reduces the length that the Achilles tendon stretches each time you step, making it more comfortable to go about your daily routine. Proper Footwear- Low-heeled shoes with good arch support and shock absorption are best for the health of your foot. Look into heel wedges and other shoe inserts to make sure that your everyday foot mechanics are operating under ideal conditions.
