Overview The Achilles tendon is at the back of the heel. It can be ruptured by sudden force on the foot or ankle. If your Achilles tendon is ruptured you will be unable to stand on tiptoe, and will have a flat-footed walk. It is important to diagnose and treat this injury as soon as possible, to help promote healing. Treatment involves wearing a plaster cast or brace (orthosis) for several weeks, and possibly having an operation. Causes The Achilles tendon usually ruptures as a result of a sudden forceful contraction of the calf muscles. Activities such as jumping, lunging, or sprinting can cause undue stress on the Achilles tendon and cause it to rupture. Often there is a background of Achilles tendinitis. Direct trauma to the area, poor flexibility or weakness of the calf muscles or of the Achilles tendon and increasing age are some of the other factors that are associated with an Achilles tendon rupture. Symptoms If you rupture your Achilles tendon, you may hear a snapping or popping sound when it happens. You will feel a sudden and sharp pain in your heel or calf (lower leg). It might feel like you have been kicked or hit in the back of your leg. You may also have swelling in your calf. be unable to put your full weight on your ankle, be unable to stand on tiptoe, or climb stairs, have bruising around the area. If you have any of these symptoms and believe you have ruptured your Achilles tendon, go straight to accident and emergency at your local hospital. If you partially rupture your Achilles tendon, the tear may only be small. Symptoms of pain and stiffness may come on quite suddenly like a complete rupture, but may settle over a few days. Diagnosis To diagnose an Achilles tendon injury, your health care provider will give you a thorough physical exam. He or she may want to see you walk or run to look for problems that might have contributed to your Achilles tendon injury. Non Surgical Treatment Two treatment options are casting or surgery. If an Achilles tendon rupture is untreated then it may not heal properly and could lead to loss of strength. Decisions about treatment options should be made on an individual basis. Non-surgical management traditionally is selected for minor ruptures, less active patients, and those with medical conditions that prevent them from undergoing surgery. The goal of casting is to allow the tendon to slowly heal over time. The foot and ankle are positioned to bring the torn ends of the tendon close together. Casting or bracing for up to 12 weeks or more may be necessary. This method can be effective and avoids some risks, such as infection, associated with surgery. However, the likelihood of re-rupture may be higher with a non-surgical approach and recovery can take longer. Surgical Treatment There are two different types of surgeries; open surgery and percutaneous surgery. During an open surgery an incision is made in the back of the leg and the Achilles tendon is stitched together. In a complete or serious rupture the tendon of plantaris or another vestigial muscle is harvested and wrapped around the Achilles tendon, increasing the strength of the repaired tendon. If the tissue quality is poor, e.g. the injury has been neglected, the surgeon might use a reinforcement mesh (collagen, Artelon or other degradable material). In percutaneous surgery, the surgeon makes several small incisions, rather than one large incision, and 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. For sedentary patients and those who have vasculopathy or risks for poor healing, percutaneous surgical repair may be a better treatment choice than open surgical repair.
