The healing rate after internal fixation of femoral neck fracture varies from person to person. Generally, the fracture healing rate is high, more than 90%, but the existence of other conditions such as femoral head necrosis will affect the healing. There are many internal fixation procedures for femoral neck fracture, such as closed reduction hollow tension screw, power hip screw internal fixation, etc., which can promote the fracture healing after internal fixation with a view to restoring the function of hip joint activities. However, due to the differences in different populations, such as population differences, underlying conditions of the body, etc., which will affect the prognosis, the general fracture healing rate is higher, which can be as much as 90% or more. As for the not degree of femoral neck fracture, the heavier the fracture, the more serious the blood supply of the femoral head, so the prognosis and cure rate is worse, such as femoral neck comminuted fracture or elderly femoral neck fracture, the chance of femoral head necrosis significantly higher, which leads to internal fixation cure rate significantly lower. After internal fixation surgery for femoral neck fracture, regular observation is also needed to understand the healing of the fracture and the condition of the femoral head, which can be done by consulting with a professional doctor.
