Is it a better option for young patients with femoral neck fracture to be placed with four cannulated screws during reduction and internal fixation

Abstract

Aim To compare the efficacy of three cannulated screws and four cannulated screws in the treatment of femoral neck fracture. Methods This is a retrospective study.A total of 215 patients were enrolled for the study. Patients who received four cannulated screws were included in the observation group, while patients who received three cannulated screws were included in the control group. Both groups were followed up for at least 1 year. The general data and surgical conditions of the two groups were compared. Results A total of 213 patients were included in the study. Among them, 97 patients received four cannulated screws and were included in the observation group. The remaining patients were included in the control group. There was no significant difference in the basic data of these patients. The patients in the observation group had longer actual operation and more intraoperative bleeding, and the difference was statistically significant.At the same time, the patients in the observation group also need to receive more intraoperative X-ray fluoroscopy times, and the difference is statistically significant.Compared with the patients in the control group, the patients in the observation group had better Harris score and hip joint activity, whether 6 months or 1 year after operation, and the difference was statistically significant.At the same time, the number of patients with delayed fracture healing or nonunion in the observation group was also relatively low, and the difference was also statistically significant.There were fewer cases of femoral head necrosis or unequal length of lower limbs in the observation group than in the control group, but the difference was not statistically significant. Conclusion Four cannulated screws should be considered for fracture fixation in young patients with femoral neck fractures. This fixation method has the advantage of fast healing time, and the range of motion and functional score of patients' hip joint will also have more advantages.
