What causes painful Achilles tendon?

Achilles Tendon Injury Physical Therapy


Overview
Achilles Tendinitis
The Achilles tendon is an important part of the leg. It is located just behind and above the heel. It joins the heel bone to the calf muscles. Its function is to help in bending the foot downwards at the ankle (this movement is called plantar flexion by doctors). If the Achilles tendon is torn, this is called an Achilles tendon rupture. The tear may be either partial or complete. In a partial tear, the tendon is partly torn but still joined to the calf muscle. With complete tears, the tendon is completely torn so that the connection between the calf muscles and the ankle bone is lost.

Causes
The exact cause of Achilles tendon ruptures is hard to say. It can happen suddenly, without warning, or following an Achilles tendonitis . It seems that weak calf muscles may contribute to problems. If the muscles are weak and become fatigued, they may tighten and shorten. Overuse can also be a problem by leading to muscle fatigue . The more fatigued the calf muscles are, the shorter and tighter they will become. This tightness can increase the stress on the Achilles tendon and result in a rupture. Additionally, an imbalance of strength of the anterior lower leg muscles and the posterior lower leg muscles may also put an athlete at risk for an injury to the Achilles tendon. An Achilles tendon rupture is more likely when the force on the tendon is greater than the strength of the tendon. If the foot is dorsiflexed while the lower leg moves forward and the calf muscles contract, a rupture may occur. Most ruptures happen during a forceful stretch of the tendon while the calf muscles contract. Other factors that may increase the risk of Achilles tendon rupture include. Tight calf muscles and/or Achilles tendon. Change in running surface eg: from grass to concrete. Incorrect or poor footwear. A change of footwear eg: from heeled to flat shoes. It is thought that some medical conditions, such as gout, tuberculosis and systemic lupus erythematosus, may increase the risk of Achilles tendon rupture.

Symptoms
Patients often describe a feeling of being kicked or hit with a baseball bat in the back of the heel during athletic activity. They are unable to continue the activity and have an extreme loss of strength with the inability to effectively walk. On physical examination there is often a defect that can be felt in the tendon just above the heel. A diagnosis of an Achilles tendon rupture is commonly made on physical exam. An MRI may be ordered to confirm the suspicion of a tear or to determine the extent of the tear.

Diagnosis
The actual area of an Achilles tendon rupture cannot be seen on x-ray. Therefore, although x-rays Where are the femur tibia and fibula? often done to rule out bony injuries in individuals with an Achilles tendon rupture these x-rays are usually normal. Diagnostic ultrasound of the tendon can be performed to assess the integrity of the tendon. Other diagnostic tests, such as MRI's, may also be required in difficult cases.

Non Surgical Treatment
Non-surgical treatment of Achilles tendon rupture is usually reserved for patients who are relatively sedentary or may be at higher risk for complications with surgical intervention (due to other associated medical problems). This involves a period of immobilization, followed by range of motion and strengthening exercises; unfortunately, it is associated with a higher risk of re-rupture of the tendon, and possibly a less optimal functional outcome.

Surgical Treatment
A completely ruptured Achilles tendon requires surgery and up to 12 weeks in a cast. Partial tears are sometimes are treated with surgery following by a cast. Because the tendon shortens as it heals, a heel lift is used for 6 months or more after the cast comes off. Physical therapy to regain flexibility and then strength are begun as soon as the cast is off.
