[Research progress on joint replacement for hemiplegic femoral neck fracture]

With China's aging society, the number of patients with hemiplegia caused by cerebrovascular accident is increasing gradually. The risk of hip fracture in the first year after the onset of this kind of patients is 4 times higher than that of ordinary people, and most of them occur in the side of hemiplegia. For senile femoral neck fracture, artificial joint replacement is almost the first choice of treatment, with mature operation technology and good curative effect. At present, it is considered that if the muscle strength of hemiplegic side can reach grade III after cerebral vascular accident, hip arthroplasty can be the first choice for hemiplegic patients with hemiplegic femoral neck fracture. However, the situation of hemiplegic patients is different from that of ordinary people. The hemiplegic limbs may have muscle atrophy, muscle strength imbalance, osteoporosis and other problems, which brings difficulties to the formulation of surgical plan. This paper mainly discusses the choice of surgical approach, the use of total hip arthroplasty or hemiarthroplasty, the use of cemented prosthesis or cementless prosthesis, and how to reduce the incidence of postoperative dislocation The purpose is to provide more reference evidence for orthopedic doctors in clinical decision-making.
