Modified Single Posterior Fixation Of Complicated Acetabular Fractures With A Percutaneous Cannulated Screw And A Reconstruction Plate

Objective According to the pelvis specimens, to analyze and discuss the efficacy of a modified single posterior fixation of complicated acetabular fractures with a percutaneous cannulated screw and a reconstruction plate in comparison with traditional bilateral approaches (ilioinguinal and Kocher-Langerbeck). Method 1. collect 12 bilateral pelvis specimens and artificially make acetabular fractures, then treat them through the modified single posterior approach by which a percutaneous cannulated screw was applied, going through skin and ischial tuberosity, to fix the anterior column and a reconstruction plate to fix the posterior column.2. From June 2005 to May 2009,26 cases of acetabular fractures were treated surgically. Of them,12 cases were bilateral approaches and 14 cases were modified single posterior fixation with a percutaneous cannulated screw and a reconstruction plate. Result 26 patients were treated successfully and they were all followed up for 6 to 37 months (average 6 months). The operation time of bilateral approaches and single posterior fixation with a percutaneous cannulated screw are (182.24±40.56) (90.75±20.12) min. The volume of hemorrhage during operation are (1735.20±535.40) (1054±264.21) ml; There were no statistical differences in anatomic reduction rate and functional good-to-excellent rate. But there were significant differences in operation time and volume of hemorrhage during operation. Conclusion The treatment of modified single posterior fixation of complicated acetabular fractures with a percutaneous cannulated screw and a reconstruction plate has the advantages of less operation time, less bleeding and easy operating.
