Fractures that do not heal usually do not have numbness. Consider other causes such as nerve damage if numbness is present. Three months after the fracture does not heal, may be delayed healing, infection and other factors. 1. Delayed healing: When the femoral neck is fractured, the surrounding nerves are severely damaged. Delayed healing may occur due to less blood supply around the fracture of the neck of the femur, which is more difficult to heal, or due to improper post-fracture care and frequent activities. 2. Infection: Femoral neck fracture is more serious, improper postoperative care may lead to infection at the fracture site, which will affect the healing of the fracture, and there will be pain, swelling and other symptoms. Localized numbness and abnormal sensation may be caused by nerve damage after the fracture, which has little to do with the non-healing of the fracture. The fracture of the neck of the femur does not heal for three months with numbness, it is recommended to find out the cause, and standardized treatment under the guidance of the doctor, to avoid adverse effects.
