Background: Despite the increased frequency of cephalomedullary fixation for unstable intertrochanteric hip fractures, failure with screw cut-out and varus collapse remains a significant failure mode. Proper positioning of implants into the femoral neck and head directly influences the stability of fracture fixation. Visualization of the femoral neck and head can be challenging and failure to do so may lead to poor results; Obstacles include patient positioning, body habitus, and implant application tools. We present the "Winquist View," an oblique fluoroscopic projection that shows the femoral neck in profile, aligns the implant and cephalic component, and assists in implant placement. Methods: With the patient in the lateral position, the legs are scissored when possible. Following standard reduction techniques, the Winquist view is used to check reduction prior to surgical draping. Intraoperatively, we rely on a perfect image to place implants in the ideal portion of the femoral neck, with a trajectory that achieves the center-center or center-low position of the femoral neck. This is achieved by incorporating the anterior-posterior, lateral, and Winquist view. Results: We present 3 patients who underwent fixation with a cephalomedullary nail for intertrochanteric hip fractures. The Winquist view facilitated excellent visualization and positioning in all cases. All postoperative courses were uneventful, without failures or complications. Conclusion: While standard intraoperative imaging may be adequate in many cases, the Winquist view facilitates optimal implant positioning and fracture reduction. With lateral imaging, implant insertion guides may obscure visualization of the femoral neck during which Winquist view is the most helpful. Level of Evidence: V.
