ORIF stands for open reduction and internal fixation. It's a type of surgery that is used to repair broken bones that need to be put back together. During the surgery, some form of hardware is used to hold the bone together so it can heal.

ORIF through ilioinguinal approach

5. Reduction and preliminary fixation
Reduction of the anterior wall fragment
The anterior wall fragment reduction is remarkably difficult. The external surface of the fragment is almost entirely articular cartilage, therefore adjuncts such as screws or joysticks threaten the joint surface.

It is difficult to apply Schanz screws, as there is very little extraarticular ilium available.
Screw based reduction clamps are precluded as bicortical screws in the anterior wall fragment threaten the articular surface. Unicortical screws may be used, however, pull out is a risk.
Unicortical adjuncts, hooks, ball spike pushers and carefully applied clamps are utilized to manipulate the fragments. In this example, K-wires have been placed unicortically to manipulate the fracture fragment.

Open reduction techniques
A variety of reduction tools may be used to manipulate the fracture fragments.

A clamp (eg Farabeuf) may be used to grasp the iliac crest to manipulate and reduce the fragment.

A ball spike pusher may also be used to aid in reduction. The ball spike may be placed along the pelvic brim (as illustrated) or alternatively, the ball spike may be placed at the anterior inferior iliac spine directed posteriorly.
