Tuberosity of the tibia of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when the foot strikes the ground. The two ligaments, the patella, and the tibial tuberosity are all superficial, easily palpable structures. Tibial tuberosity fractures are infrequent fractures, most common in adolescents. In running and jumping movements, extreme contraction of the knee extensors can result in avulsion fractures of the tuberosity apophysis. A cast is all that is required if the fragment is not displaced from its normal position on the tibia. However, if the fracture fragment is displaced, then surgery is
Ligament of head of femur Ligament of head of femur In human anatomy, the ligament of the head of the femur (round ligament of the femur, ligamentum teres femoris, or the foveal ligament) is a ligament located in the hip. It is triangular in shape and somewhat flattened. The ligament is implanted by its apex into the antero-superior part of the fovea capitis femoris and its base is attached by two bands, one into either side of the acetabular notch, and between these bony attachments it blends with the transverse ligament. It is ensheathed by the synovial membrane, and varies greatly in strength in different
