Sign IM Nail and Interlocking Screw System Technique Manual page 29

NOTE: Distal and proximal refers to the nail rather than the bone, figure 9.
NOTE: If you wish to compress the fracture site, place one interlocking screw in the nail hole nearest
the knee. The locking bolt is struck to move the distal fracture fragment toward the proximal
fragment, figure 10. Different from the antegrade approach.
Proximal interlock
NOTE: See technique used in all approaches on page 11.
Manipulate the knee into flexion and extension after the nail insertion and interlock has been
accomplished. Continue range of motion and strengthening exercises after the surgery. If the fracture
is stable, we advise weight-bearing as tolerated.
