Intended Use

The GraftCage™ ACX is a vertebral body replacement device intended to replace a collapsed, damaged, or unstable vertebral body in the thoracic or lumbar spine (TI-L5). The GraftCage™ ACX is indicated for a partial or total vertebrectomy for cases of tumor or trauma (i.e., fracture). The GraftCage™ ACX is intended to achieve anterior decompression of the spinal cord and neural tissues and to restore the height of a collapsed vertebral body. The GraftCage™ ACX is intended for use with supplemental internal spinal fixation systems that are cleared by FDA for use in the thoracic and lumbar spine. These systems include posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems. The use of bone grafting material with the GraftCage™ ACX is optional.

Device Story

GraftCage™ ACX is a vertebral body replacement (VBR) implant; rectangular, PEEK-OPTIMA polymer construction; features central/lateral fenestrations for bone graft material; superior/inferior ridges for migration resistance; tapered posterior aspect for insertion. Used in thoracic/lumbar spine surgery following vertebrectomy; implanted by surgeons using a dedicated threaded insertion tool. Device restores vertebral height and achieves anterior decompression. Requires supplemental internal fixation (pedicle screw/rod or plate systems). Benefits include structural support for collapsed/damaged vertebrae.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Material: PEEK-OPTIMA polymer. Form factor: Rectangular, lordotic or parallel configurations, tapered posterior. Features: Axial/lateral fenestrations for bone graft, superior/inferior ridges for fixation. Energy source: None (mechanical implant). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring partial or total vertebrectomy in the thoracic or lumbar spine (T1-L5) due to tumor or trauma (fracture). Must be used with supplemental internal spinal 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.

#### Device Description:

The GraftCage™ ACX is a device designed to replace a thoracic or lumbar vertebral body and to support axial compression loads following vertebrectomy for the treatment of spinal tumors and in bases of spinal trauma/fracture. The GraftCage™ ACX is made from implantable PEEK-OPTIMA (polyetheretherketone) polymer.

The GraftCage™ ACX is basically rectangular in shape. One central (axial) fenestration and one fenestration on each lateral aspect (on certain sizes) provide locations for the addition of bone grafting material. The superior and inferior aspects have ridges that resist expulsion and for migration after implantation. The device offers lordotic and non-lordotic i.e., parallel configurations. The posterior aspect of both design configurations is tapered, or bulleted, for ease of insertion.

A single threaded hole at the posterior aspect interfaces with the insertion tool. The insertion tool is a shaft attached to a handle. The shaft has a threaded end that matches the threaded hole on the GraftCage™ ACX and allows the surgeon to hold the GraftCage™ ACX while implanting it into the patient.

## Intended Use:

The GraftCage™ ACX is a vertebral body replacement device intended to replace a collapsed, damaged, or unstable vertebral body in the thoracic or lumbar spine (TI-L5). The GraftCage™ ACX is indicated for a partial or total vertebrectomy for cases of tumor or trauma (i.e., fracture). The GraftCage™ ACX is intended to achieve anterior decompression of the spinal cord and neural tissues and to restore the height of a collapsed vertebral body.

The GraftCage™ ACX is intended for use with supplemental internal spinal fixation systems that are cleared by FDA for use in the thoracic and lumbar spine. These systems include posterior pedicle screw and rod systems, anterior plate systems, and anterior screw and rod systems. The use of bone grafting material with the GraftCage™ ACX is optional.

## Comparison to Predicate:

The GraftCage™ ACX claims substantial equivalence to:

- Osteotech, Inc. VBR, K012254 1)
- DePuy AcroMed VBR System, K030833/K031635; 2)
- Spinal Concepts Fortitude Vue Vertebral Body Replacement Device, K05100; and 3)
- Implex Corporation Hedrocel Vertebral Body Replacement System, K010378. 4)

This claim of substantial equivalence is intended to reflect FDA's definition of substantial equivalence as defined by 21 CFR Part 807, Subpart E and is not intended to reflect a claim of substantial equivalence in terms of intellectual property.

The GraftCage™ ACX and the predicate devices have the same intended use and similar technological characteristics. Performance data demonstrates that the GraftCage™ ACX meets or exceeds functional requirements for a vertebral body replacement device.
