[Marginal impaction in acetabular fractures].
OBJECTIVE
To understand the diagnosis and treatment of marginal impaction of acetabular fractures.


METHODS
Eighteen of 26 patients with marginal impaction of acetabular fractures were retrospectively reviewed. Marginal impactions was confirmed in 15 patients by CT scan before operation, and in 3 during operation. All patients were treated by ORIF, and the impacted bones were elevated with bone grafts (Bone graft was not used in one patient). All fractures were fixed with a reconstruction plate.


RESULTS
The mean follow up was 36.7 months (5 - 71 months). The modified D'Aubingne and Postel score system showed excellent results in 6 patients, good 7, fair 2, and poor 3.


CONCLUSIONS
Posterior fractures and dislocations of acetabular fractures are easily combined with marginal impaction, and can diagnosed by CT scan. Cortical impaction should be recognized as a special type. The impacted bone should be elevated for bone grafting.
