Do Long-Segment Blocking Screws Increase the Stability of Intramedullary Nail Fixation in Proximal Tibia Fractures, eliminating the "Bell-clapper Effect?"

Blocking screws are commonly used to aid in fracture alignment during intramedullary nailing of proximal tibia fractures. Even when not required to attain or maintain alignment, the addition of a blocking screw in the distal (long) segment may help mitigate the "Bell-clapper Effect" in geriatric patients.
