The Clinical Efficacy Of RM Pressfit And Traditional Metal Prosthesis In The Treatment Of Femoral Neck Fractures In The Elderly Person

ObjectiveTo explore the clinical efficacy of RM pressfit and traditional metal prosthesis in the treatment of senile femoral neck fracture,and to provide guidance and treatment for patients with senile femoral neck fracture,so as to actively improve hip replacement in patients with senile femoral neck fracture After the clinical treatment effect and quality of life.MethodA total of 90 patients with femoral neck fractures aged 65 years and older who were admitted to our hospital from October 2014 to March 2018 were selected.The selected patients met the inclusion criteria.The follow-up cases were complete.The patients were displaced femoral neck fractures(Garden III type,Type IV).According to the intraoperatively placed prosthesis,the control group and the RM group were divided into 45 patients in each group.The control group used traditional metal prosthesis for surgery,and the RM group used RM elastic one prosthesis.The age and sex of the two groups were There were no significant differences in fracture classification,comorbidities,and the American Society of Anesthesiologists(ASA)scores.The RM elastic iliac crest was used to treat the femoral neck fracture in the elderly by comparing the hospitalization time of the two groups,postoperative related indicators,surgery-related concomitant conditions,medical imaging evaluation results,and Harris score of the last follow-up to evaluate postoperative hip joint function.The clinical efficacy was analyzed in depth.ResultAfter 12-48 months of follow-up,X-ray examination showed no signs of sinking and loosening of the prosthesis.There was no significant difference between the operation time of the RM group,the amount of blood loss during the operation and the cost of the hospital during the treatment period(P>0.05).Two patients(4.44%)had early complications after surgery in the RM group,and one patient(2.27%)had early complications after surgery.There was no significant difference between the two groups(χ~2=0.3448,P=0.5571).As of the last follow-up,1 patient in the RM group developed cerebral infarction,and no sequelae were left after symptomatic treatment;2 patients had dislocation of the hip joint,and the anesthesiologist assisted in the manual reset.After the reset,the imaging showed that the reset was successful,and the function recovered after the reset.Good;1 patient inadvertently fell after the operation caused the periprosthetic fracture,in our hospital(postoperative joint surgery)incision,reduction,internal fixation,the hip function is now good.There were 5 cases of concomitant disease in the control group,including 3 cases of postoperative prosthesis dislocation and 1 case of periprosthetic fracture(the hip joint function recovered well after symptomatic treatment).One patient developed deep vein thrombosis of the lower extremity,and no obvious left after symptomatic treatment.Aftereffects.There was no significant difference in hospitalization time,operation time,intraoperative bleeding time,postoperative drainage volume,treatment cost and hospitalization time(P>0.05);postoperative joint function,degree of discomfort,normal function of hip joint and postoperative operation There was no difference in Harri score between the joint function and the control group(P>0.05).ConclusionHip replacement for the treatment of senile femoral neck fractures has the advantages of good postoperative hip function recovery and low early and mid-term complications.It is currently the main method for the treatment of senile femoral neck fractures.The hip function Harris score after treatment with RM pressfit was equal to that of a conventional metal prosthesis.
