Comparison of Combined Pressure Internal Fixation System and Hollow Nail in the Treatment of Femoral Neck Fracture in Young and Middle-Aged Patients
Objective:To compare the clinical efficacy of combined pressure internal fixation system(CCS)and hollow screw in the treatment of femoral neck fracture in young and middle-aged patients.Methods:Clinical data of young and middle-aged patients with femoral neck fracture treated from January 2020 to May 2022 were retrospectively analyzed,and the patients were divided into hollow screw group and CCS group according to different internal fixation methods.There was no significant difference in baseline data between the two groups.Intraoperative reduction mode,Garden index,opera-tion time,intraoperative blood loss,intraoperative fluoroscopy times,incidence of complications during hospitalization,par-tial weight bearing time,complete weight bearing time,fracture healing time,Harris score of hip joint,fracture nonunion and incidence of femoral head necrosis were compared between the two groups.Results:There were no statistically signifi-cant differences in intraoperative reduction mode,Garden index,operation time,intraoperative blood loss,intraoperative fluoroscopy times,and complications during hospitalization between the two groups(P＞0.05).The partial weight bearing time,complete weight bearing time and fracture healing time in CCS group were significantly shorter than those in hollow screw group,and the differences were statistically significant(P＜0.05).The Harris score of CCS group was significantly higher than that of hollow-scrcw group at 3 months and the last follow-up,and the difference was statistically significant(P＜0.05).The total incidence of fracture nonunion and femoral head necrosis was 21.2％and 20.0％in the hollow screw group and CCS group,respectively,with no significant difference(x2=0.013,P=0.588).Conclusion:Both CCS and hollow screw can be used as effective internal fixation meth-ods for middle-aged and young femoral neck fractures.Compared with hollow screw,CCS can shorten the fracture healing time and weight-bearing time,and is more conducive to the functional recovery of hip joint.
