Distal interlocking with fluoroscopic guidance
The leg must be positioned so that precise images can be obtained. The central ray of the fluoroscope must pass through the locking hole so that its image is perfectly round, and centered on the display screen. This confirms that the central ray is perpendicular to the nail.
The leg is elevated on folded linen or other material, and carefully supported to maintain the desired reduction (length, rotation and angulation). The C-arm is positioned to permit imaging while the entry site is located and drilled. Leave enough room for instruments between the image source and the patient’s leg.
