The consequences of non-union of femoral neck fracture are serious and the disability rate is high. The treatment of non-healing or slow healing of the femoral neck can be divided into early treatment and late treatment. Early treatment can be done by crutches to protect and reduce weight bearing of the affected limb, application of drugs to promote bone scab growth, giving local shock wave and hyperbaric oxygen treatment, Chinese medicine treatment is also effective for non-healing of the femoral neck, and the specific treatment is decided according to the patient’s age, function, physical condition and bone density. For end-stage treatment, young patients with femoral head can use screws and substitute bone graft surgery due to sufficient bone mass, or even through osteotomy orthopedic surgery, and osteoporotic elderly patients with non-healing femoral neck with shortening deformity or hip dysfunction can solve the problem through hip replacement surgery.
