Type A:

• Stable injuries: include avulsion fractures, isolated pubic ramus fractures, iliac wing fractures or single stable fractures elsewhere in the pelvic ring.
• Avulsion fractures occur at the point of attachment of muscles:
• Anterior inferior iliac spine: rectus femoris; often resulting from a mis-kick into the ground.
• Anterior superior iliac spine: sartorius.
• Ischial tuberosity: hamstrings.
