What is the Biceps Femoris Tendon?
The biceps femoris is one of the three hamstring muscles. The muscle is made up of two separate muscle bellies, which originate from different sites, namely a long head and a short head. The long head originates from a region at the back of the hipbone called the ischial tuberosity. The short head originates from the back of the femur (thigh bone). Both muscle bellies join together, cross the knee joint and insert into the top outer surface of the two shinbones, the tibia (inner) and fibula (outer). As with all the hamstrings it has a dual function, both to bend the knee and extend the hip. What is avulsion of the Biceps Femoris Tendon? The biceps femoris is commonly injured in sports that require explosive bending of the knee as seen in sprinting. If the athlete is fatigued or has not warmed up properly he/she may suffer a hamstring strain/rupture, which is the tearing of the hamstring muscle. Avulsion of the biceps femoris tendon is the complete pulling away of the tendon from the bo
