The Achilles tendon is the strongest and thickest tendon in human body. The Achilles tendon is vascularized through two arteries, tibial posterior and peroneal arteries, and innervated by the sensory nerves by the sural nerve and nerve cutaneus. Like many other tendons, Achilles tendon doesn't have real tendon sheath. Instead it is surrounded by paratenon composed of soft tissue. Load that cause stretching greater than 8-10% of the length of the Achilles tendon cause its complete rupture. Achilles tendon rupture is more common in males, with a male-female ratio of 7: 1 to 12:1. Achilles tendon Rupture of the n on the left side is more common than on the right side,probably due to the greater prevalence of individuals where the right side is dominant and resist with the left lower part,extremity. Typically, acute Achilles tendon rupture occurs in men who are 30 to 40 years old, dealing with office jobs and occasionally sports. Simultaneous bilateral rupture of the Achilles tendon is rare in healthy individuals, as can occur in older people who suffer from a disease that has long received steroid medication. The exact causes of Achilles tendon rupture are still unclear, but the literature is full of theories, including repetitive microtrauma, disorder inhibitor mechanism, the link rupture with blood group zero, hypoxia, tendon degeneration, reduced perfusion resulting in deterioration of the systemic or topical use of steroids. The Achilles tendon is often affected by overuse injuries, depending on the localization of inflammatory changes, it is a miotendinitis, tendinitis, paratenonitis or entenzitis. Rupture of the Achilles tendon is characteristic of the last stage of overuse injuries. Clinical signs include: a very tangible dent in the dorsal flexion of the foot immediately after the injury, and the hollow very quickly fills the swelling and bruise, hematoma, severe pain on pressure, and a positive Thompson test. Most of the techniques and procedures described in the treatment of acute rupture of the Achilles tendon can be divided into 3 groups: open surgery, percutaneous surgery and conservative treatment. The main task of rehabilitation certainly return full flexibility, but then thickened and stiff tendons. Another task is strengthening the weakened muscles of lower leg as well as the return of the tendon reflex responses through proprioceptive exercises. Particular attention should be given to the ankle and small joints of the foot, which may be the cause of pain after removal of plaster.Physiotherapist help accelerate the rehabilitation process and prevents the possibility of re-injury by giving proper advices.
