Because bipedal walking requires humans to balance on a relatively unstable ball and socket joint, the placement of the vertebral column closer to the hip joint allows humans to invest less muscular effort in balancing. [7] Change in the shape of the hip may have led to the decrease in the degree of hip extension, an energy efficient adaptation.
This max extension takes place right before toe off. The hip flexors then concentrically act to initiate hip flexion for swing phase. Overall, approximately 30 degrees of flexion and 10 degrees of extension (from neutral) are needed at the hip joint for a normal walking pattern.
The sole reliance on the hip joint to control the entire prosthetic limb makes fine-tuning foot placement difficult. Lowering the knee joint height was found to effectively increase the hip joint's lever arm, thereby increasing precision control of the hip joint to improve gait symmetry and increase running velocity by 26% on average.

Overview. Sudden hip pain, shooting pain, a dull ache — all can be symptoms of issues involving your hip. The hip joint contains the ball of the thigh bone and the pelvis socket.

The hip joint is classified as a ball and socket joint. This type of synovial joint allows for multidirectional movement and rotation. There are two bones that make up the hip joint and create an articulation between the femur and pelvis. This articulation connects the axial skeleton with the lower extremity.

Each innominate bone (ilium) joins the femur (thigh bone) to form the hip joint; thus the sacroiliac joint moves with walking and movement of the torso. [9] In this joint, hyaline cartilage on the sacral side moves against fibrocartilage on the iliac side. The sacroiliac joint contains numerous ridges and depressions that function in stability.
