How many columns are in the acetabulum?

The acetabulum, which is a cup-shaped socket in the pelvic bone that forms the hip joint, has two primary columns. These columns are important in the context of hip stability and biomechanics. The anterior column supports the weight of the body and provides stability during movement, while the posterior column helps in the distribution of forces through the hip joint. Understanding the structure of the acetabulum and its two-column system is crucial in orthopedic assessments and surgical interventions, particularly for hip fractures or joint replacements.
