• Attributes: Therapeutic

Intended Use

The Stackable Cage System is indicated for use in the thoracolumbar spine (i.e., T1 to L5) to replace a diseased vertebral body resected or excised for the treatment of tumors, to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The Stackable Cage System is also indicated for treating fractures of the thoracic and lumbar spine. The Stackable Cage System is designed to restore the biomechanical integrity of the anterior, middle and posterior spinal column even in the absence of fusion for a prolonged period. The Stackable Cage System is intended for use with supplemental internal fixation. The supplemental internal fixation systems that may be used with the Stackable Cage System include DePuy AcroMed titanium plate or rod systems (i.e., Kaneda SR, University Plate, M-2, ISOLA, VSP, Moss Miami, TiMX, Monarch, Profile).

Device Story

Stackable Cage System; spinal intervertebral body fixation orthosis; used for vertebral body replacement in thoracolumbar spine (T1-L5) following tumor resection or fracture treatment. Device restores height of collapsed vertebral bodies and biomechanical integrity of spinal column. Implanted by surgeons; requires supplemental internal fixation using DePuy AcroMed titanium plate or rod systems (e.g., Kaneda SR, ISOLA, Moss Miami).

Clinical Evidence

No clinical data provided; substantial equivalence based on design and material characteristics.

Technological Characteristics

Materials: Carbon-fiber reinforced polymer and titanium alloy. Form factor: Stackable cage system for vertebral body replacement. Intended for use with supplemental internal fixation systems.

Indications for Use

Indicated for patients requiring vertebral body replacement in the thoracolumbar spine (T1-L5) due to tumors or fractures; intended to achieve anterior decompression and restore vertebral height; requires use with supplemental internal fixation.

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.
