Subtrochanteric fractures are generally well treated. Subtrochanteric fractures are displaced and tend to damage the blood vessels around the femoral head, making necrosis of the femoral head more likely to occur. The fracture also does not heal easily. If the fracture is of the basal type, it is better than the subtalar type, and there is less damage to the blood vessels around the fracture, so the fracture is easy to heal. If the fracture is young and not much displaced, closed reduction and internal fixation can be performed. If the elderly, there is obvious displacement can be taken to artificial femoral head replacement, the day after the operation, you can walk on the ground with a walker, straight leg raising exercise, to increase muscle strength, usually 3 months to return to normal. Therefore, the prognosis of femoral head fracture is affected by many factors, should actively seek medical treatment, under the guidance of the doctor for standardized treatment and rehabilitation.
