Abstract:
OBJECTIVE:To explore the anti-shear force,stability and plasticity of reconstruction plate implantation,and to investigate its role in treating acetabular fractures complicated by free bone graft in the joint.METHODS:A computer-based online search of Science Direct and Ei databases (1960-01/2009-10) was performed for related English articles with the keywords of "acetabular fractures,modified ilioinguinal approach,reconstruction plate".In addition,CNKI and CBM database (1994-01/2009-10) were searched for related Chinese articles with the same key words in Chinese.Moreover,related works were manually searched.Studies regarding reconstruction plate implantation in treating acetabular fractures were included,including basic and clinical experiments.RESULTS:Acetabular top is weight loading region of human body,and the fracture should be reducted by the operation.Prior to reconstruction plate for acetabular fracture fixation,bone hook,and Kirschner wire can be used for temporary fixation,and the plate bending angle should be adjusted to accordant with lateral posterior wall or medial anterior wall of the acetabular top,followed by screw threading for fracture fixation.In addition,the screw entrance angle is very important.If the fixation of one plate is not satisfactory,one or two cancellous bone screw or Kirschner wire can be used to enhance the fixation.But the Kirschner wire tail should be bended to prevent dislocation into the pelvic cavity.Moreover,additional plate can be used for further fixation.Reconstruction plate fixation has advantages of anti-shear force,high stability and plasticity,which fully adapt the special appearance of acetabulum.Moreover,the incidence of postoperative plate loosening and breakage is low,and the satisfaction is high.Free bone blocks can be temporarily fixed by Kirschner wire,followed by reconstruction plate fixation.CONCLUSION:Reconstruction plate fixation has good clinical effect and few complications in treating acetabular fractures complicated by free bone blocks in the joint.
