    Abstract:
    Objective This study was performed to explore the treatment of central dislocation of the femoral head without involvement of the acetabular columns. Methods Preoperatively, a three-dimensionally printed model of the patient's pelvis was manufactured according to the patient's computed tomography data. An all-locking anatomical plate was designed based on the mirror of the ipsilesional semi-pelvis. The fracture was reduced using reduction forceps and femoral traction via the lateral rectus approach. The customized plate was used as a template for reduction of the quadrilateral plate fracture. Results Reduction and fixation of this patient's fracture was achieved with a customized all-locking anatomical plate with a propeller shape via the lateral rectus approach. Conclusions This report describes an isolated quadrilateral plate fracture with central dislocation of the femoral head without involvement of the columns, which is a rare injury that has not yet been classified. It was effectively treated using a customized all-locking anatomical plate with propeller shape via the lateral rectus approach.
