Abstract:
This study showed a case of a patient with central dislocation of the femoral head without involvement of anterior or posterior column of the acetabulum. The patient was associated with endocrine disorders caused by pituitectomy, severe osteoporosis caused by a long-term gulucocorticoids intake history, and poor bone quality of the quadrilateral plate. The direct impact of the femoral head on the quadrilateral plate after trauma resulted in purely central dislocation of the femoral head. 3D printing technique was used to print the fracture model for observation of the fracture morphology and the simulated operation before surgery. The variable-angle locking acetabular plate with a propeller-like shape was designed on the basis of the mirror of the ipsilesional semi-pelvis. This fracture was reduced via the lateral-rectus approach under direct vision. The quadrilateral surface fractures were fixed by the variable-angle locking acetabular plate which was used as a template for reduction. The follow up after surgery showed good reduction and fixation, equal length of double lower limbs, good positive and passive motion of the injured hip joint and without perioperative complications. This report describes an isolated quadrilateral plate fracture that has not yet been classified. It was effectively treated by using a customized variable-angle locking acetabular plate with a propeller-like shape via the lateral rectus approach.
