The hip joint has less freedom of movement than the shoulder joint because the articulating parts of the hip are closer together than those of the shoulder. This limits the range of motion of the hip joint, whereas the shoulder joint has a wider range of motion due to the structure and design of its articulating parts. The joint capsule, muscles, and synovial fluid also contribute to the differences in mobility between the two joints, but the distance between the articulating parts is the primary factor.
