【Abstract】 Objective To investigate the relationships between residual displacement of weight-bearing and non weight-bearing zones (gap displacement and step displacement) and hip function by analyzing the CT images after reconstruction of acetabular fractures. Methods The CT measures and clinical outcome were retrospectively analyzed from 48 patients with displaced acetabular fracture between June 2004 and June 2009. All patients were treated by open reduction and internal fixation, and were followed up 24 to 72 months (mean, 36 months); all fractures healed after operation. The residual displacement involved the weight-bearing zone in 30 cases (weight-bearing group), and involved the non weight-bearing zone in 18 cases (non weight-bearing group). The clinical outcomes were evaluated by Merle d’Aubigné-Postel criteria, and the reduction of articular surface by CT images, including the maximums of two indexes (gap displacement and step displacement). All the data were analyzed in accordance with the Spearman rank correlation coefficient analysis. Results There was b negative correlation between the hip function and the residual displacement values in weight-bearing group (rs= — 0.722, P=0.001). But there was no correlation between the hip function and the residual displacement values in non weight-bearing group (rs=0.481, P=0.059). The results of clinical follow-up were similar to the correlation analysis results. In weight-bearing group, the hip function had b negative correlation with step displacement (rs= — 0.825, P=0.002), but it had no correlation with gap displacement (rs=0.577, P=0.134). Conclusion In patients with acetabular fracture, the hip function has correlation not only with the extent of the residual displacement but also with the location of the residual displacement, so the residual displacement of weight-bearing zone is a key factor to affect the hip function. In patients with residual displacement in weight-bearing zone, the bigger the step displacement is, the worse the hip function is.
