ACETABULAR
FRACTURES
The fracture disrupts the congruence of the femoral head with
the acetabulum and causes damage to the articular surface.
A small number of fractures will be combined acetabular and
pelvic ring injuries.
Evaluation
History and physical findings are similar to those in pelvic
ring fractures.
| :: |
Evaluate
and treat hypovolaemic shock and visceral organ damage
as an emergency (see page 13–8). |
| :: |
Evaluate
sciatic nerve function and look for an associated femoral
shaft fracture. |
| :: |
Obtain
an initial anterior-posterior pelvic X-ray. If a fracture
is evident, oblique views show the articular surfaces
more clearly. X-ray the femoral shaft. |
Treatment
Minimally displaced fractures
Treat minimally displaced fractures with bed rest and gradual
mobilization. When comfortable, begin partial weight bearing
until fracture healing has occurred. This usually takes about
12 weeks.
Displaced and unstable fractures
Treat displaced and unstable fractures with traction to maintain
the congruence of the femoral head with the weight-bearing
portion of the acetabulum. If a satisfactory position cannot
be maintained, or if there are bone chips within the hip joint,
surgical stabilization is indicated.
Do not send the patient to another hospital unless you are
certain that this complicated surgery is available there.

Acetabular
fractures result from high-energy pelvic injuries
|
 |
 |
Treatment
aims to restore the congruence of the femoral head
with the acetabulum by traction or by surgery if available
|
|
 |
Complications
include deep venous thrombosis, sciatic nerve injury
and late degenerative arthritis of the hip.
