Clinical correlation
Avulsion fractures of the hip bone
A fracture of the hip bone is a fracture of the pelvis (see ch. 6). The expression «hip fracture», on the other hand, is usually used loosely for the head, neck or trochanters of the femur. In an avulsion, a sudden sprint or braking (sprinting, kicking, hurdling, basketball, martial arts) makes the tendon pull off a piece of the bone where it attaches. It happens at the prominences of muscle attachment: anterior superior iliac spine (sartorius), anterior inferior iliac spine (rectus femoris), ischial tuberosity (hamstrings) and ischiopubic rami.
