The anatomy and biomechanics of the hip joint

Abstract:
The human hip is the largest ball and socket joint in the body. It differs in design from the more common hinge joint in order to meet the requirements of ambulation. The hip is an inherently stable joint because of its bony structure and its extensive ligamentous and muscular support. Regardless of this stability, the hip joint maintains a wide functional range of movement. This dichotomy of function has resulted in a complex organization of joint structure. A thorough understanding of the biomechanic forces exerted across the joint surfaces is essential to the understanding of both normal and pathologic function.The authors of this article will explore the complex structural anatomy of this joint system in light of the biomechanic principles that effect movement and weight bearing through the joint.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Anatomical Movements
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
