Classification

• stable vs. unstable
• breaks in the ring
• posterior arch vs. anterior arch OR both
• single bone without break of ring
• acetabular
• mechanism LC, AP, VS

3
Stable

• low speed mechanisms
• falls from low height
• athletic injuries
• most common pubic ramus/body
• Other transverse sacral, coccyx,
  apophyseal/avulsion injuries

4
Unstable

• involve both anterior and posterior arches
• mechanisms
• high speed MVCs or fall from height
• lateral compression ? transverse pubic rami ,
  iliac wing, sacrum
• anterior compression ? open-book injury,
  longitudinal rami
• vertical shearing forces
• SI joint subluxation/dislocation, symphyseal
  diastasis

5
associated injuries

• pelvis is boney ring find one fracture, look
  for another
• subluxation/dislocation SI jt or pubic symphysis
• acetabulum/femoral head/joint fragments
• pelvic contents
• bladder/urethra, rectalsigmoid, vagina/uterus,
  vasculature, nerve

6
acetabular

• types
• posterior
• ilioischial column
• transverse
• iliopubic
• associated with hip dislocation

7
avulsions

• ASIS sartorius
• AIIS rectus femoris
• ischial tuberosity hamstring (kicking)
