Your hip joint provides vital shock absorption to the torso and upper body as well as stability during standing and other weight-bearing activities.
Your hip is comprised of four main components:
Bones of the hip
Your hip is a ball-and-socket joint uniting two separate bones – the thighbone, or femur, and the pelvis. Your pelvis features two cup-shaped depressions called sockets or acetabulum. One is on either side of the body. Your thighbone is the longest bone in the body and connects into the pelvis at your hip joint. The head of the thighbone is shaped like a ball and fits tightly into the socket, forming the ball-and-socket joint of the hip.
Cartilage of the hip
The socket is lined with cartilage, which cushions your bones during weight-bearing activities and allows the joint to rotate smoothly and freely in all directions with minimal friction.
Ligaments of the hip
The complex system of ligaments connects your thighbone to the pelvis and is essential for stability, keeping your hip from moving outside of its normal range of motion.
