Summary

Femoral neck fracture is a common type of fracture in the elderly. For those without significant displacement (Garden I, II), more hip-preserving treatment strategies are adopted. The classic parallel hollow screw internal fixation for hip-preserving treatment is based on the sliding compression theory, and a clinical debate has gradually emerged, that is, the positive triangle And the two different spatial distribution methods of hollow nails and inverted triangle, which one is better. In addition, the distribution of hollow nails in actual operations is difficult to achieve a standard triangular distribution, and the damage to the epiphyseal vessels in the femoral head caused by repeated drilling of the guide needle cannot always be ignored. The relationship between the distribution and injury of blood vessels in the femoral head and the spatial distribution of hollow screws on the prognosis of head necrosis of non-displaced femoral neck fractures in the elderly is worth studying. This topic is based on the three advantages of TianJi orthopedic robots used in the elderly femoral neck fracture hollow nail hip-saving surgery: 1.standardized triangular nail placement with strong repeatability; 2. precise nail placement to reduce the risk of screw penetration; 3. limited guide pins The number of drill holes is to rule out repeated drill holes that damage the blood vessels in the femoral head. The preoperative and postoperative vascular injury in the femoral head (enhanced MRI of the femoral head) was compared to assess the prognosis of patients, and to clarify the influence of the spatial distribution of hollow screws on the blood supply and prognosis of the femoral neck fracture in the elderly.
