Introduction
The hip joint is the articulation between the pelvis and the lower limb, serving as the most critical center for locomotion in the lower extremities. When the thigh moves, the joint located at the junction of the thigh and buttock is the hip joint. It is one of the largest and most mobile joints in the human body. Moreover, due to the robust surrounding musculature—including the gluteal muscles and proximal musculature of the femur—it is also one of the most stable large joints in the body.
The hip joint is the articulation between the pelvis and the lower limb, serving as the most critical center for lower-limb locomotion in the human body. When the thigh moves, the joint located at the junction of the thigh and buttock is the hip joint.
The hip joint consists of the acetabulum of the pelvis and the femoral head—the uppermost portion of the femur—united together via the joint capsule and surrounding ligaments. It is one of the largest and most mobile synovial joints in the body. Moreover, due to robust muscular support from the gluteal muscles and proximal thigh musculature, it is also among the most stable large joints.
The hip joint exists bilaterally (left and right), acting as the central枢纽 connecting the trunk to the lower limbs and serving as the primary node for force transmission between them. The joint capsule surrounding the hip is exceptionally strong, further reinforced by powerful ligaments. Consequently, hip dislocation is relatively uncommon under normal physiological conditions; however, under high-energy traumatic mechanisms, hip dislocation, avascular necrosis of the femoral head, or femoral neck fracture may occur.
