IntroductionBiomechanical studies have compared fixation methods in transverse acetabular fractures, yet there is not enough clinical data to suggest an optimal fixation method. The aim of this randomized controlled trail was to compare fracture stability in posterior plating alone versus posterior plating and anterior column lag-screw fixation in treatment of transverse and transverse with posterior wall acetabular fractures.MethodsThirty patients were randomized to one of two groups, either posterior fixation alone (single column group), or posterior plating and anterior fixation with percutaneous anterior column screw (double column group). Patients were followed up with serial radiographic assessments documenting any loss of reduction, utilizing Matta's radiological criteria, measuring the roof arc angles and by measuring any change in the femoral head offset.ResultsFifteen patients were randomized to each group. Mean patient age was 31 years, mean follow up period was 19 months (range 12–24). There was no significant differences between the two groups with regards the quality of post-operative reduction, blood loss, hospital stay and functional score using the modified Merle D'Aubinge and Postel score. The operative time was significantly longer in the double column fixation group (130 min versus 104 min). There was no loss of reduction observed in either of the two groups.ConclusionSingle poster column fixation in transverse and transverse posterior wall fractures showed similar result to double column fixation, in terms of fractures stability in the follow up period, quality of reduction and early functional outcome.
