ABSTRACT
Objective To explore the clinical curative effects of hip replacement in the treatment of femoral neck fracture and femoral head necrosis in elderly patients and the existing problems.Methods A total of seventy-five aged patients with femoral neck fracture or femoral head necrosis who were treated by hip replacement were selected as study objects.They were divided into fracture group and femoral head necrosis group according to disease type,all the patients were treated with hip replacement.The surgical time,intraoperative blood transfusion volume,length of hospital stay,in-bed time,perioperative complications and postoperative complications were observed and recorded.The Harris score was used to evaluate hip function of preoperation and postoperation.Results All patients were followed up for 6 ～ 24 months,no incision infection and severe perioperative complications.The volume of intraoperative blood loss,operation time,hospitalization time,in-bed time of the fracture group were (334.9 ± 90.4) mL,(91.7 ± 14.3) min,(19.5 ± 7.5) d,(5.9 ± 1.6) d,respectvely,which of the femoral head necrosis group were (362.9 ± 71.5) mL,(93.5 ± 7.8) min,(20.5 ± 4.2) d,(6.3 ± 1.4) d,respectvely,the differences between the two groups were not statistically significant (all P ＞ 0.05).At the end of the follow-up,the Harris scores of the two groups were higher than before operation,and the score of the fracture group (89.0 ± 7.4) points was significantly higher than (84.0 ± 9.2) points of the femoral head necrosis group (t =19.639,P ＜ 0.05).In the fracture group,1 year after surgery,1 patient appeared delayed fracture healing,2 cases with postoperative pain when walking the affected area.In the femoral head necrosis group,1 case with femoral nerve injury,1 case of death due to its original diseases,1 case of postoperative sore pain when walking,the two groups had no prosthesis loosening or dislocation phenomenon.Conclusion Hip replacement in the treatment of femoral neck fracture and femoral head necrosis in elderly patients can be used as a clinical treatment option with short in-bed time,less intraoperative blood loss,short operation time,less perioperative complication and good treatment effect,and it is worth to be promoted.
