When a tendon ruptures it can be extremely painful and cause a disability of the foot that then subsequently causes damage to the ankle joints. The tendons in the ankle include: the peroneals (peroneus brevis, peroneus longus,) anterior tibialis, posterior tibialis, and Achilles tendon. Any of these structures can become ruptured, which is a serious condition that will typically require surgery to fix.
Often an Achilles rupture can occur spontaneously without any prodromal symptoms. Unfortunately the first "pop" or "snap" that you experience is your Achilles tendon rupture. Achilles tendon rupture most commonly occurs in the middle-aged male athlete (the weekend warrior who is engaging in a pickup game of basketball, for example). Injury often occurs during recreational sports that require bursts of jumping, pivoting, and running. Most often these are tennis, racquetball, squash, basketball, soccer, softball and badminton. Achilles rupture can happen in the following situations. You make a forceful push-off with your foot while your knee is straightened by the powerful thigh muscles. One example might be starting a foot race or jumping. You suddenly trip or stumble, and your foot is thrust in front to break a fall, forcefully over stretching the tendon. You fall from a significant height. It does appear that previous history of Achilles tendonitis results in a degenerative tendon, which can grow weak and thin with age and lack of use. Then it becomes prone to injury or rupture. Certain illnesses (such as arthritis and diabetes) and medications (such as corticosteroids and some antibiotics) can also increase the risk of rupture.
The most common symptom of Achilles tendonitis is a sudden surge of pain in the heel and back of the ankle at the point of injury which is often described as a snapping sensation in the heel. After the injury has occurred, patients then struggle or find it near impossible to bear any weight on the affected leg. Pain can often be most prominent first thing in the morning after the injury has been rested. Swelling and tenderness is also likely to appear in the area.
Diagnosis is made mostly by clinical examination with a defect usually noted on visual examination and by touching the area. A simple test can be done by squeezing the back of the calf with the foot resting in the air. Normally when squeezing the muscle belly the tendon will shorten causing the foot to move in a downward position. With a rupture this squeezing effect may show no movement of the foot if it is not attached properly. A negative test does not mean there isn't some degree of rupture as some of the tendon fibers may still be attached. Sometimes x-rays, an mri, or an ultrasound can be helpful in determining the extent of the rupture.
Non Surgical Treatment
Your doctor may advise you to rest your leg and keep the tendon immobile in a plaster cast while it heals. Or you may need to have an operation to treat an Achilles tendon rupture. The treatment you have will depend on your individual circumstances, such as your age, general health and how active you are. It will also depend on whether you have partially or completely torn your tendon. If you have a partial tear, it might get better without any treatment. Ask your doctor for advice on the best treatment for you. If you need pain relief, you can take over-the-counter painkillers such as paracetamol or ibuprofen. Always read the patient information that comes with your medicine and if you have any questions, ask your pharmacist for advice.
There are two types of surgery to repair a ruptured Achilles tendon. In open surgery, the surgeon makes a single large incision in the back of the leg. In percutaneous surgery, the surgeon makes several small incisions rather than one large incision. In both types of surgery, the surgeon sews the tendon back together through the incision(s). Surgery may be delayed for about a week after the rupture, to let the swelling go down.
