Device Description
The Spinal Concepts, Inc. BacFix™ ti Spinal Fixation System consists of a combination of titanium components which include rods, hooks, locking wedges, screws and transverse connectors which are indicated to provide temporary stability of the thoracic, thoracolumbar or lumbar spine (TI-S1). The BacFix™ Spinal Fixation System consists of longitudinal members (spinal rods), in diameters of 5.5 and 6.0mm, in two hardnesses, and a variety of lengths; spinal anchor components, hooks and screws (mono-axial and multi-axial) of various diameters (5.0, 6.0, 7.0 and 8.0mm) and lengths; locking connectors (threaded wedge and nut or non-threaded wedge and locking clip) sized to fit the spinal rods; and a transverse connector assembly (link), also in various lengths. Hooks and screws may be placed at any position along the spinal rods. Wedges are used to connect the spinal rods to screws (hooks and links). These components are preassembled outside the wound, eliminating the need to pre-plan the position of each eyebolt on the spinal rod. A spinal rod is positioned within the open face of the wedge. Fixation of the construct is accomplished using an instrument that applies a three point shear clamp. Addition of the hex nut (when using threaded wedge) and optional use of the locking clip (when using the non-threaded wedge) complete the implant. Anchor components may be added to (or removed from) the construct at any time during the procedure.
