After a femoral neck fracture, whether it is treated surgically or conservatively, it is more likely to have serious complications such as non-healing of the fracture and femoral head necrosis. Therefore, it is not possible to judge whether the fracture has healed or not by the standard of 3 months, and it is necessary to go to the hospital for regular review of the film. If the fracture is not completely healed at 3 months, you should not lose the crutches at all and continue to use them to protect the fracture side from gravity. Early weight bearing may lead to non-healing of the fracture and in severe cases can lead to necrosis of the femoral head, even with surgical treatment. Therefore, do not judge the time to abandon crutches by the time after the fracture, you must go to the hospital for regular review of the film to show the complete healing of the fracture as the standard before you can judge whether you can throw away the crutches.
