The hip joint is a large strong ball and socket joint that also allows a considerable degree of movement in all directions. The top of the thigh bone forms the ball section, while the socket (acetabulum) sits in the pelvis angled slightly down and forward. The acetabulum is relatively shallow to allow the amount of movement required. In order to improve the range and stability of the hip the acetabulum has a continuous wedge of cartilage running around it – this is called the labrum.
The hip is one of the most significant joints in human development as it is where we started to stand upright from. We have evolved over many thousands of years to be on two feet all day and be physically active. Unfortunately today’s sedentary, sit-down society means that for most of the day our hips are not doing what they are designed for.
