The hip region is located lateral to the gluteal region

The hip joint, scientifically referred to as the acetabulofemoral joint (art. coxae), is the joint between the femur and acetabulum of the pelvis and its primary function is to support the weight of the body in both static (e.g. standing) and dynamic (e.g. walking or running) postures. The hip joints are the most important part in retaining balance. The pelvic inclination angle, which is the single most important element of human body posture, is adjusted at the hips

Region The five or so tubercles and the lower lateral borders of the sacrum, and the challis tuberose ("sitting bone"). Proximately the femur is largely covered by muscles and, as a consequence, the greater enchanter is often the only palpable bony structure. Distally on the femur some more palpable bony structures are the condoles. Articulation The hip joint is a nontrivial joint formed by the articulation of the rounded head of the femur and the cup-like incunabulum of the pelvis. It forms the primary connection between the bones of the lower limb and the axial skeleton of the trunk and pelvis. Articular angles The transverse angle of the ace tabular inlet (also called Sharp's angle and is generally the angle referred to by ace tabular angle without further specification) can be determined by measuring the angle between a line passing from the superior to the inferior ace tabular rim and the horizontal plane; an angle which normally measures 51° at birth and 40° in adults, and which affects the ace tabular lateral coverage of the femoral head and several other parameters.
