The best way to visualize the movement pattern of the sacrum is to consider gait, in which sacral movement reciprocates with the ilia. In order to accommodate the two opposing iliac movements, the articular surfaces are shaped like an airplane rotor, imparting a twisting motion [1-4]. However, instead of the rotor spinning, the central body rotates, as the sacrum pivots about the prescribed paths formed into the articular surfaces of the sacrum and ilia at the sacroiliac joints, one on each side. During right nutation, the right side of the sacral base pivots anteriorly and inferiorly as the right ilium moves posteriorly and inferiorly; at the same time, the left side of the sacral base pivots posteriorly and superiorly as the left ilium moves anteriorly and superiorly. As the two ilia reverse movement, the sacrum pivots accordingly [5, 6].

The attachment of the wings to the body of the plane is comparable to the sacroiliac joint. Unlike the wings of a plane, which float freely in an open system, allowing a firm attachment to the body of the plane, the innominates are part of a closed system, which necessitates a slight amount of flexibility at their attachment to the sacrum, which is provided by the ligaments. Too much laxity will impede control and too little motion will reduce the normal pumping mechanism of the joint; either will be detrimental to stability.

Sacral motion can be compared to that of an airplane undergoing pitch, roll, and yaw, where sacral flexion/extension is comparable to pitch, sacral rotation is comparable to roll, and sacral lateral flexion is comparable to yaw. The combined movement around these three axes, each centered in the body of the sacrum, represents sacral motion.

No, magnifying glasses are not designed to correct vision and using them as a substitute for eye glasses can actually cause more harm to your eyes. Eye glasses are specifically tailored to an individual's prescription and vision needs, while magnifying glasses are meant for magnifying objects at a close distance.

Using magnifying glasses or eye glasses that are not prescribed or fitted properly can cause eye strain, headaches, and blurred vision. It is important to consult with an eye doctor to ensure you are using the correct prescription and properly fitted glasses to avoid any potential health risks.

The main difference is their purpose and design. Magnifying glasses are used for magnifying small objects, whereas eye glasses are used for correcting vision. Additionally, magnifying glasses typically have a single convex lens, while eye glasses have two lenses (one for each eye) that can be customized for different prescriptions.

Yes, magnifying glasses and eye glasses can be used together to achieve better magnification and vision correction. However, it is important to consult with an eye doctor to ensure that the combination of lenses will not cause any discomfort or harm to your eyes.

Magnifying glasses work by using convex lenses to bend and focus light, making objects appear larger and closer. Eye glasses, on the other hand, use corrective lenses to compensate for refractive errors in the eye, improving vision.
