The Mechanical Effect of Blocking Screws ("Poller Screws") in Stabilizing Tibia Fractures With Short Proximal or Distal Fragments After Insertion of Small-Diameter Intramedullary Nails

Abstract

The study suggests that medial and lateral blocking screws can increase the primary stability of distal and proximal metaphyseal fractures after nailing and can be an effective tool for selected cases that exhibit malalignment and/or instability.
