Objective To compare the effectiveness of femoral neck system(FNS)and inverted triangle cannulated screws(ITCS)in the treatment of femoral neck fractures in young adults.Methods A retrospective study was conducted on 106 young and middle-aged patients who had been surgically treated for femoral neck fracture at our hospital from December 2020 to June 2022.The patients were assigned to FNS group(57 cases)or ITCS group(49 cases)according to the different internal fixations.The operation time,intraoperative fluoroscopy frequency,intraoperative blood loss,extra assisted reduction procedures(Kirschner wire prying reduction or open reduction),hospital stays,healing time,complications,postoperative recovery,and follow-up duration were compared between the two groups.Results The operation time,fluoroscopy frequency,and healing time in the FNS group were less than those in the ITCS group(P<0.001).The shortening degree and length of femoral neck in moderate and severe patients of the FNS group were lower than those of the ITCS group(P<0.001).The Harris score of the FNS group was higher than that of the ITCS group 12 months after surgery(P<0.001).There was no significant difference in intraoperative blood loss,reduction assistance,Garden index,or hospital stays between the two groups(P>0.05).Conclusion FNS is a better choice for internal fixation in patients with femoral neck fractures than ITCS,with faster recovery and less postoperative complications.
