Biomechanics of the Artificial Hip Joint

Key Points Muscle forces play an integral role in the loading environment of the hip. If the mechanical role of major muscles is neglected in biomechanical analyses, joint contact forces tend to be underestimated, the tensile and compressive strains in…

Biomechanics of the Natural Hip Joint

Key Points The physiologic range of motion (ROM) of the hip is affected by many morphologic and soft tissue factors that are not well understood. Clearly, systemic factors, such as age and joint degeneration, impair motion. However, ethnicity, sex, and…
