Central dislocation of femoral head without involvement of acetabular anterior and posterior columns

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.
