Abstract: Objective:To evaluate the clinical efficacy of bipolar femoral head replacement for Garden stage Ⅲ and Ⅳ femoral neck fracture patients accompanied with Parkinson’s disease.Methods:23 bipolar femoral head replacement were performed in femoral neck fracture patients with Parkinson's disease.Artificial bipolar femoral head replacement for displaced femoral neck fractures was performed and its efficacy was evaluated.Results:The average blooding loss was（220.0±34.5）ml（120～360ml）.The average operating time was（65.0±10.5）min（50～75min）.Followup was lost in 4 patients，2 patients died of cardiovascular and cerebrovascular events at 3 and 9 months after surgery，and 1 patient died of pulmonary infection at 14 months after surgery.Common postoperative complications were pneumonia，deep vein thrombosis and urinary tract infection.The Harris hip score was excellent in four patients，good in twelve patients，fair in four patients and poor in one patients after one year operation.Two patients died at 3 and 9 months postoperatively without scoring，excellence rate was 69.6%.Conclusion:Bipolar femoral head replacement is a satisfactory treatment for the femoral neck fractures in patients accompanied with Parkinson's disease，but the incidence of complications is high and the function recovery is difficult.
