Intended Use

The Z-Span Plate System is intended for use via the lateral or anterolateral surgical approach above the bifurcation of the great vessels in the treatment of the lumbar spine (L1-L5) or via the anterior approach below the bifurcation of the great vessels in the treatment of the lumbar and lumbosacral spine (L1-S1). The Z-Span Plate System is intended to provide immobilization and stabilization as an adjunct to fusion in skeletally mature patients in the treatment of the following: Fracture (including dislocation and subluxation) Tumor Degenerative Disc Disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies) Pseudoarthrosis Spondylolysis Spondylolisthesis Scoliosis Lordotic deformities of the spine Spinal stenosis Failed previous spine surgery

Device Story

Z-Span Plate System is a supplemental spinal fixation device consisting of titanium alloy plates and screws. Used by surgeons in the lumbar and lumbosacral spine (L1-S1) to provide immobilization and stabilization as an adjunct to fusion. The device is implanted via lateral, anterolateral, or anterior surgical approaches depending on the spinal level. By securing the vertebral bodies, the system stabilizes the spine to facilitate fusion, potentially reducing pain and correcting deformities associated with conditions like degenerative disc disease, fractures, or scoliosis. The system is a mechanical implant; it does not involve software, algorithms, or electronic components.

Clinical Evidence

No clinical data. Bench testing only. Mechanical testing (static/dynamic axial compression, bending, and static torsion) conducted per ASTM F1717.

Technological Characteristics

Spinal intervertebral body fixation orthosis. Materials: Titanium alloy (Ti-6AL-4V ELi) per ASTM F-136. Design: One-level lumbar and sacral plates and screws. Mechanical testing performed per ASTM F1717.

Indications for Use

Indicated for skeletally mature patients requiring immobilization and stabilization as an adjunct to fusion for fracture, tumor, degenerative disc disease, pseudoarthrosis, spondylolysis, spondylolisthesis, scoliosis, lordotic deformities, spinal stenosis, or failed previous surgery in the lumbar/lumbosacral spine (L1-S1).

Regulatory Classification

Identification

A spinal intervertebral body fixation orthosis is a device intended to be implanted made of titanium. It consists of various vertebral plates that are punched into each of a series of vertebral bodies. An eye-type screw is inserted in a hole in the center of each of the plates. A braided cable is threaded through each eye-type screw. The cable is tightened with a tension device and it is fastened or crimped at each eye-type screw. The device is used to apply force to a series of vertebrae to correct “sway back,” scoliosis (lateral curvature of the spine), or other conditions.
