Pathological Human Left Femur (819-822) Healed misaligned fracture. Homo sapiens sapiens. Pathological Human Left Femur is museum quality polyurethane resin cast. Features healed misaligned fracture. Made in the USA. Polyurethane cast from a private collection.

The human femur or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates (for example, the largest bone of the human thigh). The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap, forming the knee joint.

By most measures the two (left and right) human femurs are the strongest bones of the body, and in humans, the longest.

The human femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have wider pelvic bones, causing their femora to converge more than in males.

The human femur is the longest and, by some measures, the strongest bone in the human body. This depends on the type of measurement taken to calculate strength. Some strength tests show the temporal bone in the skull to be the strongest bone.

The human femur is categorised as a long bone and comprises a diaphysis (shaft or body) and two epiphyses (extremities) that articulate with adjacent bones in the hip and knee.

The head of the femur, which articulates with the acetabulum of the pelvic bone, comprises two-thirds of a sphere. It has a small groove, or fovea, connected through the round ligament to the sides of the acetabular notch.

The head of the femur is connected to the shaft through the neck or collum. The neck is 4 to 5 cm. long and the diameter is smallest front to back and compressed at its middle.
