Overview
A rupture of the Achilles tendon means that there has been either a complete, or partial, tear of the tendon which connects the calf muscles to the heel bone. Usually this occurs just above insertion on the heel bone, although it can happen anywhere along the course of the tendon.
Causes
Inflammation/strain of the tendon is usually caused by overuse, for example, frequent jumping in volleyball, netball or basketball. It is often also caused by a sudden increase in certain types of training, such as hill sprinting or track running, particularly when running in spikes. Tendinopathy can also be associated with ageing. Our ability to regenerate damaged tissue decreases as we age and the quality of the tendon deteriorates. However, the better news is that sensible training can actually strengthen all our soft tissue (tendons, ligaments and muscle). Tightness in the calf muscles will demand greater flexibility of the tendon, which inevitably results in overuse and injury. Biomechanically, the tightness can reduce the range of dorsiflexion (toe up position) in the ankle, which increases the amount and duration of pronation. This problem is known as overpronation.* This reduces the ability of the foot to become a rigid lever at push off and places more lateral and linear forces through the tendon. This imbalance can translate into altered rotation of the tibia (shin bone) at the knee joint and, in turn, produce compensatory rotation at the hip joint with subsequent injuries to the shin, knee and hip. Pronation is part of the natural movement of the subtalar joint in the foot. It allows eversion (turning the sole outwards), dorsiflexion and abduction (pointing the toes out to the side). Pronation is a normal part of the gait cycle, when walking and running, and it helps to provide shock absorption in the foot. When pronation is excessive, the foot has a tendency to roll inward more than normally acceptable. One sign of overpronation is greater wear on the inside of your running shoes than on the midsole. Lack of stability around the ankle joint can also be a contributory factor, as recurrent ankle sprains appear to be associated with a high incidence of Achilles tendonopathy. Wearing shoes that dont fit or support the foot properly can be a major contributing cause of Achilles tendon injury.
Symptoms
You may notice the symptoms come on suddenly during a sporting activity or injury. You might hear a snap or feel a sudden sharp pain when the tendon is torn. The sharp pain usually settles quickly, although there may be some aching at the back of the lower leg. After the injury, the usual symptoms are a flat-footed type of walk. You can walk and bear weight, but cannot push off the ground properly on the side where the tendon is ruptured. Inability to stand on tiptoe. If the tendon is completely torn, you may feel a gap just above the back of the heel. However, if there is bruising then the swelling may disguise the gap. If you suspect an Achilles tendon rupture, it is best to see a doctor urgently, because the tendon heals better if treated sooner rather than later. A person with a ruptured Achilles tendon may experience one or more of the following. Sudden pain (which feels like a kick or a stab) in the back of the ankle or calf, often subsiding into a dull ache. A popping or snapp
