Application of pre-inserting a needle via lateral hip zoning method in the surgery of percutaneous hollow screw internal fixation for treatment of femoral neck fractures
Objective:To explore the applied value of pre-inserting a needle via lateral hip zoning method in the surgery of percutane-ous hollow screw internal fixation for treatment of femoral neck fractures(FNFs).Methods:The medical records of 60 patients who under-went percutaneous hollow screw internal fixation for FNFs from March 2018 to March 2022 were analyzed retrospectively.The patients who received pre-insertion of a needle via lateral hip zoning method for assisting hollow screw implantation were assigned into the lateral hip zon-ing group,while the ones who underwent implantation of hollow screw based on the surgeon's experiences into the tradition group.The intr-aoperative X-ray exposure,operative time,intraoperative drilling times,fracture healing time and Harris hip score evaluated at the last fol-low-up were recorded and compared between the 2 groups.Results:One patient withdrew from each group due to undergoing hip replace-ment for femoral head necrosis.The results of evaluation on intraoperative X-ray exposure,operative time,intraoperative drilling times and fracture healing time were better in lateral hip zoning group compared to tradition group(10.5±2.3 vs 25.4±7.3 times,t=7.657,P=0.011;41.7±5.6 vs 55.7±15.6 minutes,t=4.576,P=0.015;4.5±1.2 vs 14.5±2.1 times,t=16.756,P=0.021;5.6±1.5 vs 7.0±0.6 months,t=5.987,P=0.032);while,the comparison of Harris hip score evaluated at the last follow-up between the 2 groups re-vealed no significant differences(90.3±2.7 vs 90.1±1.2 points,t=1.205,P=0.301).Conclusion:Implantation of hollow screws assis-ted by pre-inserting a needle via lateral hip zoning method is similar to implantation of hollow screws based on the surgeon's experiences in the degree of hip function recovery in percutaneous hollow screw internal fixation for treatment of FNFs;while the former displays the advan-tages of fewer intraoperative X-ray exposure and intraoperative drilling,shorter operative time and fracture healing time compared to the latter.
