Final answer:
A fractured femur is surgically repaired by inserting an intramedullary rod into the femur, which is then anchored with screws for stabilization.
Step-by-step explanation:
During the surgical repair of a fractured femur, stabilization is typically achieved through the insertion of an intramedullary rod into the marrow (medullary) space of the femur. This involves drilling a hole into the greater trochanter, enlarging the marrow space, and then inserting the rod. Once in place, the rod is anchored with screws to secure both portions of the broken femur. This method is designed to allow the bone to heal properly while maintaining the alignment and strength of the femur during recovery. This procedure is commonly used in treating mid-femur fractures, which are a serious injury that can result in complications if not managed properly.
