Fixation of Acetabular Fractures. A Novel Method of Pre-Operative Omega Plate Contouring

Abstract

Pre-operative contouring of an Omega plate based on a post-injury CT scan of the uninjured half of the pelvis is over 80% accurate or almost accurate. The multi-functional 3.5-mm pelvic plate Omega allows us to stabilise complicated fractures of the superior ramus of the pubic bone, anterior acetabular column or quadrilateral plate as well as fractures above the linea arcuata or uncomplicated fractures of the posterior column. The stabilisation of all fragments of the anterior column and quadrilateral plate is very firm and the Omega plate is resistant to fragment redisplacement. Also, it is its advantage that it can remain in situ if total hip arthroplasty is required later.
