Innovations in Fracture Reduction: Poller Screws
The use of “poller” or “blocking” screws is a minimally invasive reduction technique used in intramedullary nailing of long bones. The basic objective behind the use of poller screws is to reduce the width of the medullary canal, block the nail and increase the mechanical stiffness of bone-implant construct. Their original indication, which was the reduction and supplemental stabilisation of long bone metaphyseal fractures, has been recently expanded and is currently used in the management of nonunions and in intramedullary limb lengthening. In this chapter tips and tricks as to how poller screws should be applied effectively are presented.
