What type of joint is hip joint?
The hip joint is a ball-and-socket joint that allows motion and gives stability needed to bear body weight. The socket area (acetabulum) is inside the pelvis. The ball part of this joint is the top of the thighbone (femur). It joins with the acetabulum to form the hip joint.

What kind of joints are in the shoulders and hips?
The shoulder and hip joints are the only ball-and-socket joints in the human body due to the need for great motion at the end of the body’s limbs and the vast amount of musculature needed to move and support such flexible joints. Two main components make up a ball-and-socket joint: a bone with a spherical head and a bone with a cup-like socket.
Which joint hip or shoulder is more stable?
In contrast, the acetabulum of the pelvis fully encompasses the femoral head, and this makes the hip-joint far more stable. However, whilst the hip is more stable, the shoulder has a greater range of movement. Each joint has this trade-off that is particular to its function.
