Hip Stability's Secret: The Zona Orbicularis Ligament
Anatomy researchers have long known about the zona orbicularis, a unique ligament encircling the neck of the femur. This structure plays a crucial role in hip stability.
The zona orbicularis has an irregular shape and thickness, with circular fibers derived from the hip joint's articular capsule. It forms a robust locking ring around the femur's neck, providing significant support.
This ligament is particularly prominent in the posterior and lower regions of the hip capsule. Its primary function is to stabilise the hip joint, especially during distraction movements.
The zona orbicularis, first described by anatomists studying the hip joint, is a vital component of the hip's structural integrity. Its unique circular fibers and prominent posterior position contribute significantly to hip stability.
