Abstract: BACKGROUND: Femoral neck fracture is a common fracture in the elderly. As one of the mainstream treatment methods, internal fixation is still needed to further pursue strong fixation and reduce the incidence of complications as much as possible.  
OBJECTIVE: To compare the short-term effectiveness of the femoral neck system and cannulated compressive screws for femoral neck fracture in elderly patients.
METHODS: The clinical data of 35 elderly patients with femoral neck fractures who met the research criteria from April 2020 to June 2021 were retrospectively analyzed. They were divided into the femoral neck system group (16 cases) and cannulated compressive screw group (19 cases) according to different treatment methods. There were no statistical differences between the two groups in gender, age, injured side, injury mode, fracture classification and other general data. The operation time, blood loss, postoperative hospitalization days, reduction quality, healing time, Harris score and postoperative complications of the two groups were recorded and compared. The curative effect was analyzed between the two groups.  
RESULTS AND CONCLUSION: (1) 16 patients with femoral neck system were followed up for 8-25 months (mean 11.9 months), except for 1 case of internal fixation failure. 19 patients treated with cannulated compressive screws were followed up for 7-26 months (mean 16.3 months). (2) There was no significant difference between the two groups in operation time, blood loss, postoperative hospitalization days, reduction quality, healing time, last Harris score and postoperative complications. (3) The Harris score of the femoral neck system group was significantly better than that of cannulated compressive screw group 1 month after operation (P=0.039). (4) In the femoral neck system group, there was 1 case of internal fixation failure receiving total hip arthroplasty 2 months after operation and 1 case of femoral neck shortening. In the cannulated compressive screw group, there was 1 case of femoral neck shortening with the loosening of the screw. (5) It is indicated that in the treatment of femoral neck fractures in elderly patients, the femoral neck system and cannulated compressive screws have the advantages of being minimally invasive, rapid and easy to operate. In early rehabilitation, the femoral neck system has stronger fixation strength, allowing early weight-bearing and showing better hip joint function.
