The human body's largest weight-bearing joint is the hip joint, often described as a ball-and-socket joint, encompassed by muscles, ligaments, and tendons. Formed by the connection of the thigh bone (femur) and the pelvis, the hip joint is vital for maintaining a range of motion and supporting weight-bearing activities. Any injury or disease affecting the hip can significantly impact its function, limiting mobility and weight-bearing capacity.
The hip joint comprises essential components:
The hip joint serves as the vital connection between the body's lower limb and trunk, facilitating crucial movements and comprising two essential bones—the thigh bone or femur and the pelvis—the latter consisting of the ilium, ischium, and pubis.
The femoral head forms the hip joint ball, while the acetabulum creates the socket. This deep, circular socket is shaped by the union of three bones: ilium, ischium, and pubis. The stability of the hip is ensured by the joint capsule, along with the surrounding muscles and ligaments providing support.
Within the acetabulum, the femoral head undergoes rotational movements. Adding depth to the socket is the fibrocartilaginous labrum attached to the acetabulum.
The femur, among the longest bones in the human body, comprises the femoral head, femoral neck, and greater and lesser trochanters. The head of the femur connects with the pelvis (acetabulum) to establish the hip joint. Adjacent to the femoral neck, the greater and lesser trochanters act as pivotal sites for muscle attachment.
Are you experiencing hip pain or mobility issues? Our hip specialists at Divi Orthopaedic and Rehab Center specialises in comprehensive hip treatment and care, including joint replacements and hip trauma surgeries.
Nerves of the hip transfer signals from the brain to the muscles to aid in hip movement. They also return the sensory signals such as touch, pain, and temperature to the brain.
The primary nerves in the hip region include the femoral nerve in the front of the femur and the sciatic nerve at the back. The hip is also supplied by a nerve known as the obturator nerve.
In addition to these nerves, blood vessels supply blood to the lower limbs. The femoral artery, one of the largest arteries in the body, arises deep in the pelvis and can be felt in front of the upper thigh. It, along with its branches, supplies the hip joint.
The harmonious coordination of anatomical components within the hip allows for various movements essential for daily activities and functional mobility. Hip movements encompass the following dynamic actions:
These fundamental hip movements collectively contribute to the joint's flexibility, stability, and adaptability, facilitating various activities from walking and sitting to more complex actions.

The hip joint serves as the largest weight-bearing joint in the human body, facilitating a range of movements and supporting various weight-bearing activities crucial for daily functioning.
The hip joint involves the thigh bone (femur) and the pelvis, consisting of the ilium, ischium, and pubis. The femoral head acts as the ball, and the acetabulum forms the socket, providing stability. The joint's stability is further ensured by the joint capsule, muscles, and ligaments.
Ligaments surrounding the hip joint form a robust, fibrous structure, ensuring stability. Key ligaments include the iliofemoral ligament, pubofemoral ligament, ischiofemoral ligament, ligamentum teres, and acetabular labrum, each playing a unique role in limiting over-extension and enhancing stability.
The hip joint enables various movements, including flexion, extension, abduction, adduction, circumduction, and rotation. These dynamic actions collectively contribute to the joint's flexibility, stability, and adaptability, supporting a wide range of activities.
