How to evaluate pre\u2010operatively the necessity for the performance of the posterior approach was an issue to be solved. In order to solve this issue, the computer\u2010assisted virtual surgery technique was used to evaluate if the involved PW in both\u2010column acetabular fractures (BACF) should be managed through posterior approach and verify the feasibility of this method.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data of a consecutive cohort of 72 patients with both\u2010acetabular fractures from January 2012 to January 2020 was collected for retrospective study, of which 44 patients had concomitant acetabular PW fractures, and patients without PW fractures were labeled as the BCAF group. Computer\u2010assisted virtual surgery technique was performed pre\u2010operatively to evaluate the necessity for performance of posterior approach in 44 patients, and posterior approach was required if more than 3\u2009mm of displacement was still present in the reduced 3D model. The 23 patients without treatment through posterior approach were labeled as the BCAF\u2010PW<jats:sup>\u2212<\/jats:sup> group, and the 21 patients with treatment through posterior approach were labeled as the BCAF\u2010PW<jats:sup>+<\/jats:sup> group. Operation\u2010related and post\u2010operative parameters were recorded. The quality of reduction and functional outcomes were assessed by the Matta scoring system and modified Merle d'Aubign\u00e9 and Postel scoring system. The measurement data were analyzed using the <jats:italic>t<\/jats:italic>\u2010test of independent samples and rank\u2010sum test of ranked data between every two groups.
