Final answer:
Intramedullary nailing is a surgical technique to stabilize femoral shaft fractures by inserting a metal rod inside the bone's marrow cavity, secured with screws.
Step-by-step explanation:
Intramedullary nailing is a surgical procedure used to treat femoral shaft fractures in adults. It involves the insertion of a metal rod, known as an intramedullary nail, into the marrow cavity of the femur. This procedure helps to stabilize the fracture and promote bone healing. Conducted under general or regional anesthesia, the nail is inserted through a small incision at the hip's greater trochanter. The rod runs down through the length of the femoral shaft and is anchored at both ends with screws to keep the broken bones secure. This method of fixation allows for early mobility and helps reduce the risk of complications associated with prolonged immobility, such as bedsores, deep vein thrombosis, or pulmonary embolism.
