Intended Use

Cadence and TraXis are vertebral body replacement devices that are intended for use in the thoracic and/or thoracolumbar spine (T3 - L5) to replace a collapsed, damaged or unstable vertebral body resected or excised (i.e., partial or total vertebrectomy procedures) due to tumor or trauma (i.e., fracture). These devices are designed to restore the biomechanical integrity of the anterior, middle and posterior spinal column even in the absence of fusion for a prolonged period. These devices are intended to be used with bone graft.

Device Story

Cadence and TraXis are hollow vertebral body replacement implants; used in thoracic/thoracolumbar spine (T3-L5) to replace collapsed, damaged, or unstable vertebrae post-resection/excision due to tumor or trauma. Implants feature textured opposing flat sides to facilitate stability; designed to restore biomechanical integrity of anterior, middle, and posterior spinal columns. Intended for use with bone graft. Operated by surgeons in clinical settings. Benefit: restoration of spinal column structural support.

Clinical Evidence

Bench testing only. Mechanical testing demonstrated that Cadence and TraXis exhibit the functional requirements to support their use as vertebral body replacements under normal physiologic loads in the spine.

Technological Characteristics

Materials: Titanium alloy (ASTM F136) or PEEK OPTIMA (ASTM F2026). Design: Hollow, tapered (Cadence) or various lengths/widths/heights (TraXis) with textured opposing flat sides. Energy source: None (passive implant). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring vertebral body replacement in the thoracic and/or thoracolumbar spine (T3-L5) following partial or total vertebrectomy due to tumor or trauma (fracture). Intended for use with bone graft.

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.
