Use "flexion" in a sentence
  • "_flexion_ is usually so pronounced that it can no longer be concealed by lordosis, so that when the patient is recumbent, although the spine is arched forwards, the limb is still flexed both at the hip and at the knee; with the spine flat on the table, the flexion of the thigh may amount to as much as a right angle."
  • "Muscle forces therefore must increase as the limbs become more flexed, and we show how this flexion translates to greater volumes of muscle recruited for locomotion and hence metabolic cost."
  • "Back in the mid-1980s, for example, knee replacement surgery was considered a success if the patient wound up with 90 degrees of flexion, which is "nothing near normal," he says."
