Houston Methodist. Leading Medicine  Elbow FAQ   When I
straighten my arms, my elbows always look a little bit bent.
They don't seem to straighten as much as other people's elbows.
Is there a reason for this?   When it comes to joint motion,
there is a wide range of what is considered "normal." Some
people notice their elbows don't straighten all the way, while
others have extra motion that allows the elbows to go beyond
straight. This is all genetically determined, or based on
inherited traits from your parents.  The structures around the
elbow, such as ligaments, tendons, and attaching muscles,
determine flexibility and motion. How the fibers stretch across
and around the joint and how tight or loose the fibers are
contribute to the final amount of joint motion.   Our
