Matrix Neuro System
The new Matrix Neuro plate and screw system offers a complete line of screws, plates, meshes as well as new instrumentation designed for neurosurgical fixation. It is intended for use in selective trauma of the midface and craniofacial skeleton, craniofacial surgery, and reconstructive procedures. It can also be used for selective orthognatic surgery of the maxilla and chin. Its main strength revolves around its concept of improved self-drilling low profile neuro screws which can be used in a range of plate strengths.
In order to meet the need for low profile in neurosurgical applications broad Matrix Neuro plates are 0.4 mm thick, which is significantly less than the currently existing low profile system. Still they provide maximum strength being comparable in bar stiffness. Full selections of titanium plates such as 2-hole and 4-hole dog bone, y-plate and box plate and burr hole covers are available.
The Matrix Neuro contourable mesh is available in a variety of shapes and sizes to meet the needs of the individual patient. An addition to the malleable mesh another more rigid version is available. Both versions are 0.4 mm thick. The unique design allows screw placement through either side of the mesh. It is color-coded based on strength characteristic. Specialty shapes, such as strut mesh, temporal mesh, and the mastoid mesh are available as well.
The Matrix Neuro self-drilling screws have a unique thread design for rapid screw starting and significant lower insertion torque almost instantaneously starting with bone contact. They have a deep recess cross-drive for improved retention and resistance to cam-out.
The screws are available in 3 mm, 4 mm, and 5 mm lengths (1.55 mm in diameter, emergency screws in 1.85 mm are available). They provide a fast closure of bone flaps and rapid fixation of cranial fractures. The overall plate/screw profile of the Matrix Neuro system is 0.5 mm.
The Matrix Neuro system includes newly designed instrumentation such as screwdriver blades, mesh cutters, plate benders and plate holders. It is available with an especially designed modular graphic case, which is stackable, providing a flexible and convenient means of storage. Addressing the need for quick and easy access of instruments and implants the drawers feature an improved movement and the screw holding insert is made of metal instead of plastic.
