There are no early signs of Achilles tendon rupture because it occurs in a split second, usually due to direct or indirect violence, with symptoms such as severe pain. The tendons of the gastrocnemius and flounder muscles at the back of the calf merge downward into a thick and very strong tendon called the Achilles tendon, which ends behind the calcaneal tuberosity. Its main function is to plantar-flex the ankle joint, to maintain the balance of the ankle joint and to run, jump and walk. Direct violence, such as a heavy object striking the Achilles tendon, can cause contusion, partial or complete rupture of the Achilles tendon, often accompanied by skin injury. Indirect violence is more common, mainly violent muscle contraction, such as inappropriate jumping, landing posture, etc., the calf triceps muscle sudden violent contraction, so that the Achilles tendon was torn injury. Rupture sound can be heard at the time of injury, open rupture with the presence of wounds, localized pain, calf weakness, standing and walking difficulties. The occurrence of Achilles tendon rupture, must be timely to the regular hospital, timely treatment, so as not to cause greater damage.
