What is it indicated for?

The ODi Ultimate Compression Hip Screw will be used on indications that are common with presently marketed compression hip screw systems. The primary indications are for fixation/stabilization of intertrochanteric fractures, intracapsular fractures and some high subtrochanteric fractures. The device is intended to stabilize fragments of the fracture until bony union can occur. The installed device is not intended for weight bearing prior to the fracture showing evidence of union.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
