The hip joint, also known as the COXA in Latin, is a ball and socket joint that connects the femur to the pelvis. It is one of the most important joints in the body, allowing for movement in multiple directions. The hip joint is stabilized by muscles, ligaments, and tendons, which are collectively known as the hip musculature. The hip joint is also known as the inspot, which is derived from the Latin word for 'in the spot'.
