4Screw insertion

Screw entry point

Intramedullary screws for fixation of ramus fractures may be inserted in an antegrade or retrograde fashion.

The choice of the direction of insertion depends on the location of the fracture and surgeon's preference. Ramus fractures that are located closer to the pubic symphysis are often easier to reduce and control using a retrograde screw. In contrast more proximal ramus fractures are better stabilized with an antegrade screw.
