Did you know your femur isn’t just a straight bone, but one that relies on precise angles to support balance and mobility? The angle of inclination—the tilt between the femoral neck and shaft—plays a crucial role in how we walk, run, and move. But when that angle deviates from the norm, fascinating conditions like coxa valga and coxa vara emerge. In coxa valga, the angle exceeds 135°, resulting in a straighter femur that can lead to hip instability and altered movement. In contrast, coxa vara occurs when the angle drops below 120°, creating a sharper bend that may cause leg shortening, difficulty walking, and discomfort. In this video, we’ll explore real specimens of these abnormalities from The Bone Museum’s collection, offering insights into how they affect biomechanics and are treated today. Curious to learn more?

Don’t forget to visit us in Brooklyn to see these specimens in person and dive deeper into the wonders of osteology!
