- Generally result from high energey trauma.
- ATLS resuscitation. These can be high enegery injuries, assessment should begin with the A,B,C's.
- Document neurovascular exam before and after any treatment, especially reduction of dislocated hip.
- A/P pelvis, and Judet views (45° iliac and oburator oblique views.)
- CT scan: assess for posterior pelvic ring injury, femoral head fracture, intra-articular fragments, impaction.
- Posterior Wall: posterior wall fragments <1/3 of the surface are generally stable. Fx >50% of surface are unstable. Intermiately sized fxs should undergo fluoroscopic EUA to determine stability.
- Letournel Classification
- Hip dislocation: should be reduced as soon as medically possible. Consider post-reduction traction, especially for medially displaced dislocations. Post-reduction xrays documenting reduction are required.
- Pelvic ring injury
- Femoral head fracture
- Femoral neck fracture
- Femoral shaft fracture
- PCL tear
- Knee dislocation
Acetabular Fracture Complications
- Neurologic injury
- Poor wound healing
- Chronic Osteomyelitis
- Painful hardware
- Loss of reduction
- Limb length discrepancy
- Sitting imbalance
- Gait disturbance
- DVT / PE (Borer DS, JOT 2005;19:92).
- Heterotopic ossification: Extensile (extended iliofemoral or triradiate) approaches are associated with the highest incidence of ectopic bone formation, whereas the ilioinguinal approach is rarely associated with this complication. Rates up to 45-100% are reported. The HO is most extensive when no prophylaxis is provided using extended approaches. Routine prophylaxis consists of either 1) Indomethacin 25 mg tid for 4-6 weeks, beginning POD #1 or 2) Low dose irradiation 1000 rads in divided doses or 700 rads single dose, begun before POD #4.Surgical excision is only considered when the HO severely reduces hip mobility. Preop CT scan is recommended.
- Outcome is dependent on quality of reduction.
