What is the hip joint?
The hip joint is the articulated connection between the femoral head - the upper end of the femur (femur) - and the acetabulum of the hip bone. Like the shoulder joint, it is a ball joint that can be moved around three main axes. In principle, the range of motion of shoulder and hip joint are about the same size. However, as we are predominantly walking or walking, these sizes are rarely used.
The femoral neck head is held in the socket of the hip bone by different ligaments and a strong joint capsule.How does our knee joint work?

What is the function of the hip joint?
In the hip joint, the movements of the legs compared to the pelvis, without the running, jumping, sitting, the balancing act of the ballet dancers, dancing and much more would not be possible. The three main movements are anteversion, retroversion and abduction:
In the anteversion the thigh is lifted, so there is a flexion in the hip. When the knee is bent, the leg can be raised by up to 140 degrees.
In the Retro version The thigh is stretched backwards, which is possible by about 15 degrees. A further movement to the rear is only possible if the pelvis tilts forward on the other side.
In the abduction The leg is splayed laterally to a maximum of about 45 degrees. When the leg out of this Abspreizstellung brought back to the body (adduction) and at the same time lifted forwards and turned slightly outwards, then it is possible to move this leg beyond the center line to the opposite side. Sitting and standing, we can then beat each other's legs.
These three main movements in the hip joint come one more Internal and external rotation added. These movements are best recognized when, with the leg extended, the foot is turned inwards or outwards, or when the knee is flexed, the lower leg flexes inwards or outwards. In combination of all these types of movement a leg gyration is possible.
