Marginal impaction in acetabular fractures / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To understand the diagnosis and treatment of marginal impaction of acetabular fractures.</p><p><b>METHOD</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
