1. 61-C3.1 Bilateral unstable pelvic ring injury, extrasacral on both sides

Posterior injury

Anterior injury

Posterior injury
Both posterior arch disruptions are type C1 injuries which involve:

  • Iliac fracture (C1.1 - type),
  • SI joint dislocation (C1.2 - type),or
  • SI fracture dislocation (C1.2 - type)

Anterior injury
The anterior injury is one or more of the following:

  • Symphyseal disruption
  • Pubis (uni/bilateral, ipsi/contralateral)
  • Ramus (uni/bilateral, ipsi/contralateral)

2. 61-C3.2 Bilateral unstable pelvic ring injury, ipsilateral is sacral (C1.3 - type) and contralateral extrasacral (C1.1 or C1.2 - type)

External rotation injury

Posterior contralateral injury

Anterior injury

Posterior ipsilateral injury
Ipsilateral injuries are complete vertical fractures through the sacrum.

Posterior contralateral injury
The contralateral injury is either a:

  • Iliac fracture
  • SI joint dislocation
  • SI fracture dislocation

Anterior injury
The anterior injury is one or more of the following:

  • Symphyseal disruption
  • Pubis (uni/bilateral, ipsi/contralateral)
  • Ramus (uni/bilateral, ipsi/contralateral)

3. 61-C3.3 Bilateral unstable sacral fractures

Posterior injury

Anterior injury

Posterior injury
Both posterior injuries are complete vertical fractures through the sacrum. These include complex lumbosacral dissociations and suicidal jumpers fractures. (See sacral fractures)

Anterior injury
The anterior injury is one or more of the following:

  • Symphyseal disruption
  • Pubis (uni/bilateral, ipsi/contralateral)
  • Ramus (uni/bilateral, ipsi/contralateral)
