Hip Anatomy and Biomechanics in the Athlete

Abstract

The hip is a unique joint that possesses both mobility and stability because of its anatomic configuration. This joint is crucial to athletic activities involving the lower extremity, such as running, jumping, and kicking, as well as to the generation and transference of forces for activities involving the upper extremity. The tremendous loads that the hip withstands result from muscular, gravitational, and joint reaction forces inherent in weightbearing. This article reviews the anatomy and biomechanics of the hip as a foundation for the evaluation and treatment of athletes with hip disorders.
