Answer:
The femur, particularly in elderly persons, is more likely to be fractured in the femoral neck, approximately 1 or 2 inches below the hip joint.
This can be related to osteoporosis, because of lack of calcium, bone gets thinner in this area.

Hip fractures are generally fixed with surgery, either with an internal fixation or a partial or total hip replacement, all depending on the type of fracture and patients comorbidities.
