Achilles Tendon Tears
Causes of Achilles Tendon Tears
Achilles tendon tears occur most often in athletes and middle-aged sedentary men, particularly those who are out of shape and start an intense activity or sport without gradually building up to it. The tendon is more likely to be completely torn in middle-aged men than in athletes. These injuries can occur when people do not warm up or stretch enough before intense activity. Typically, the injury occurs while running or jumping, especially if the sport requires quick changes in directions. The tendon tears when a movement pushes the toes upward, toward the shin, too forcefully and too far. Rarely, the Achilles tendon tears with no apparent cause in people who take fluoroquinolone antibiotics (such asciprofloxacin) or corticosteroids.
