* Diaphyseal fractures (proximal long nails and antegrade/retrograde nails only)

* Open and closed fractures

* Comminuted fractures

* Nonunions and malunions

* Pathologic fractures

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