Abstract

The main concern of this chapter presents the biomechanics of the hip joint. Kinesiology of the hip joint, hip joint contact areas and forces and using a stick are also discussed in this chapter. The hip is an enarthrosis or a ball-and-socket joint. The maximum range of motion is approximately 140° of flexion—extension, 75° of abduction—adduction and 90° of rotation. Using a cane in the contralateral hand on the healthy side has an effect similar to that of shifting the center of gravity of the body towards the center of rotation of the femoral head of affected side. A well-colored figure on the pelvis-free body is also provided in this chapter.
