Radiologic Outcomes of Intramedullary Nailing in Infraisthmal Femur-Shaft Fracture with or without Poller Screws

Figure 1

Intraoperative C-arm images show the procedure and position of poller-screw insertion. (a) Find the location of poller screws medial and lateral to the intramedullary nail in the metaphyseal area and drill a hole. (b) Confirm the position of the drill hole. (c) Insert one poller screw and make another drill hole. (d) Insert poller screws under C-arm guidance. (e) Confirm the final position after insertion of interlocking screws.
