The contribution of the ligamentum teres to the hip fluid seal: A biomechanics study.

Background: The suction seal of the hip plays an important role in maintaining hip stability; however, the function of the ligamentum teres in maintaining this seal remains poorly understood. This study aimed to evaluate the effectiveness of the hip suction seal in ligamentum teres deficient hips for joint positions occurring during gait.

Methods: Six fresh-frozen human cadaveric hips were dissected and mounted to an Instron materials test system.
