Abstract：Objective To evaluate the application of endo_model partial pelvis replacement acetabular fracture with ipsi_lateral neck fracture treated by total hip arthroplasty. Methods One stage THA was done in 12 patients with acetabular frac_tures combined with ipsilateral femoral neck fractures 5 ~ 18 days after fractures. All 12 patients received auto graft with Endo_model partial pelvis replacement and biological femoral stem. Harris Hip Score System and radiography were used to evaluate the clinical efficiency. Results 12 patients were followed up for 2 years and 1 months to 5 years and 7 months(mean 3 years and 9 months),which showed heterotopic ossification in one patient and no dislocation. No prothesis loosening,radiolucent lines were observed during the follow_up. None needed second revision. The mean Harris Hip Score was 90 points,51 points higher than preoperative. The hip joint function was reported to be improved obviously and no loosening of prosthesis after oper_ation in all the patients followed up. Conclusion An analysis was done on six patients with acetabular fracture with ipsilateral neck fracture treated by total hip arthroplasty by auto gaft with Endo_model partial pelvis replacement and emphasizing the sta_bility of rebuilded configuration of acetabulum. The good curative effect with acetabular fracture with ipsilateral neck fracture can be obtained by total hip arthroplasty which can avoid femoral head necrosis and other serious complications by open reduc_tion and internal fixation and improve function of hip joint significantly,avoid further operation lessen the burden of patients mentally and economically.
