Abstract: BACKGROUND: Treatment of femoral neck fracture has always been a clinical research hotspot. Minimally invasive fixation using the femoral neck system is minimally invasive in the true sense, but there is a lack of long-term follow-ups.   
OBJECTIVE: To investigate the short-term effectiveness of femoral neck system in the treatment of femoral neck fracture in high altitude areas.
METHODS:   Twenty-four patients with femoral neck fracture admitted to the Department of Trauma Orthopedics of Qinghai Provincial People’s Hospital from November 2019 to January 2021 were divided into two groups according to different internal fixation materials: a femoral neck system group (n=14) and a hollow screw group (n=10). Patients in the femoral neck system group were treated with femoral neck system internal fixation, while patients in the hollow screw group were treated with traditional hollow screw internal fixation. Symptomatic treatment was performed in all patients after operation, and the corresponding lower limb functional rehabilitation training was conducted under the guidance.   
RESULTS AND CONCLUSION: All patients were followed up for 6-20 months, and none of them developed incision infection, nonunion of fracture ends, and internal fixation failure. Patients in both groups were all satisfied with the reduction of fracture. There was no significant difference in operation time and fracture healing time between the two groups (P > 0.05). Intraoperative fluoroscopy frequency in the femoral neck system group was significantly lower than that in the hollow screw group (P < 0.05). There was no necrosis of femoral head in the two groups. During the last follow-up, the radiological examination showed no appearance of femoral neck shortening in both groups, and there was also no significant difference in Harris score of hip function between the two groups (P > 0.05). To conclude, compared with the traditional hollow screw internal fixation, the femoral neck system is characterized by less trauma and lower intraoperative fluoroscopy frequency in the treatment of femoral neck fracture in high altitude area. The femoral neck system can obtain satisfactory short-term effectiveness, which is in line with the principle of rapid trauma recovery.
