Abstract:

Combined central acetabular and femoral neck fractures with intrapelvic femoral head dislocation is an infrequent situation that provides a problematic condition for surgeons attempting to reconstruct the hip joint. Herein, we report two cases involving central acetabular fracture-dislocation combined with intrapelvic dislocation of a fractured femoral neck. Each case involved associated injuries that made primary total hip arthroplasty (THA) impossible and necessitated using the fewest skin incisions possible. As a result, we first attempted a posterior acetabular fixation of both the anterior and posterior columns with intra-articular plating of the anterior column. Finally, a cementless acetabular cup was implanted. There were no complications identified during the stages of reconstruction up to and including THA. The two patients̓ final Harris Hip scores were 98 for the first patient (at five years), and 91 for the second patient (at 1 ½ years). In conclusion, staged reconstruction of the hip joint with intra-articular acetabular plating does not weaken the acetabular bone that can accept insertion of THA with cementless biological acetabular fixation without complications and with an acceptable clinical outcome up to five years.
