DEVICE: Excella III-D® (M711LS4700)

A surgical instrument designed to facilitate the correct orientation (alignment) of an orthopaedic fixation implant, implants, or system of implants during orthopaedic surgery. It may be used, e.g., to align a series of bone screws in an implant system for posterior stabilization of the spine, or to align a spinal anatomical fixation implant. It is available in a variety of shapes and sizes and allows the surgeon to engage this device with the implant(s) and align them in the desired configuration. It is typically made of high-grade stainless steel or titanium alloy and will have profiled features to fit into the implant(s) to align them. This is a reusable device.

An assembly of non-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/or transverse connectors. Non-sterile disposable devices associated with implantation may be included.
