What is it indicated for?

The Sonoma Cancellous Screws are intended for use in the fixation of bone fractures appropriate for the size of the screw. The washer is used to increase bone contact area and prevent the screw head from subsiding into the bone. These screws are not intended for attachment or fixation to the posterior elements (pedicles) of cervical, thoracic, or lumbar spine.

Indications for use as stated in the FDA summary.
