Spinal Fixation System - Bone-screw internal spinal fixation system, sterile

Intended purpose

An assembly of sterile implantable devices intended to provide immobilization and stabilization of spinal segments in the treatment of various spinal instabilities or deformities, also used as an adjunct to spinal fusion [e.g., for degenerative disc disease (DDD)]. Otherwise known as a pedicle screw instrumentation system, it typically consists of a combination of anchors (e.g., bolts, hooks, pedicle screws or other types), interconnection mechanisms (incorporating nuts, screws, sleeves, or bolts), longitudinal members (e.g., plates, rods, plate/rod combinations), and transverse connectors. Sterile disposable devices associated with implantation may be included.
