At the basal area, femurs form a triangular surface which then forms a joint with the tibia and the patella, the knee joint. These bones are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges. femurs or femora / f m r /), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates.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 (shinbone) and patella (kneecap), forming the knee joint.By most measures the two (left . In this article, we shall look at the anatomy of the femur its attachments, bony landmarks, and clinical correlations. The head of the fibula bone is joined to the head of the tibia bone. Long bones are found in the upper limbs (humerus, ulna, radius) and lower limbs (femur, tibia, fibula), as well as in the hands (metacarpals, phalanges) and feet (metatarsals, phalanges). The fibular collateral ligament (supporting structure that attaches the fibula to the femur) also has an insertion on the lateral condyle. The head of the femur articulates with the acetabulum of the ilium or hip bone. The long bones are femur, tibia, and fibula and the sesamoid bones are the kneecaps, i.e., patella, short bones are the phalanges, tarsals, and metatarsals.
