3 Figs. 1-A and 1-B Anteroposterior and lateral fluoroscopic images showing appropriate positioning of guidewires for percutaneous placement of transphyseal screws. Figs. 1-A and 1-B Anteroposterior and lateral fluoroscopic images showing appropriate positioning of guidewires for percutaneous placement of transphyseal screws. The wires should cross the distal femoral physis in its anterior third. A true lateral view (typically using a cross-table technique) is mandatory to ensure appropriate hardware positioning.
