What is it indicated for?
The Polarus Cap Screw is intended to be used in conjunction with the Polarus Rod family cleared under K920666 and K951740. Its purpose is to engage the proximal-most 5.0 interlocking screw in the rod to prohibit/minimize backing out of that screw and to prohibit ingrowth of bone into the 1/4-20 hole.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
