The femur bone is the strongest and longest bone in the body, occupying the space of the lower limb, between the hip and knee joints.Femur anatomy is so unique that it makes the bone suitable for supporting the numerous muscular and ligamentous attachments within this region, in addition to maximally extending the limb during ambulation. The epiphysis is searate from the diaphysis because the cartilage that was present in the epiphyseal plate has decomposed, allowing these two regions of the femur to become separated. Take home message: The acetabular labrum plays a critical role in hip function and maintaining and restoring its function during surgical intervention remain an essential goal.

We will tell you about the general structure of skeleton, how bones work in dogs, common diseases that affect the skeleton and common diagnostic tests performed in dogs to evaluate the skeleton. The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament ( ligamentum teres femoris) within the socket and by strong surrounding ligaments.
