What is it indicated for?

Interlocking hip stems are indicated for non-cemented application in cases of revision, trauma, fracture, oncology or other situations where severe proximal bone loss may compromise the fixation and stability of a standard type hip replacement prosthesis.

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