The Use of Poller Screws for Metaphyseal Tibia and Femur Fractures Treated With Small-Diameter Intramedullary Nails

Summary The intramedullary nailing of metaphyseal fractures is associated with an increased incidence of deformities, which can result from instability after fracture fixation. Poller screws or blocking screws, placed adjacent to an intramedullary nail, block transverse nail translation and enhance the stability of the bone-implant construct. The purpose of this article is to describe the clinical use of blocking screws in supplementing metaphyseal tibia and femur fractures stabilized with a small-diameter, statically interlocked intramedullary nail.
