• Attributes: Therapeutic

Intended Use

When used as a vertebral body replacement device, the InFix System is intended for use in the thoracic and/or lumbar spine (T3-L5) to replace a collapsed, damaged or unstable vertebral body resected or excised (i.e., partial vertebrectorny procedures) due to tumor or trauma (i.e., fracture). The InFix 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 InFix intended to be used with bone graft. When used as an intervertebral body fusion device, the InFix System is indicated for use with autogenous bone graft at one or two contiguous levels in the lumbosacral region (12-S1) in the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. Patients with previous non-fusion spinal surgery at involved level may be treated with the device. Patients should be skeletally mature and six months of non-operative treatment. When used as an intervertebral body fusion device, the InFix implant is intended to be used with supplemental fixation. For both of the indications listed above, the InFix implant is intended to be implanted via an open anterior approach.

Device Story

Zimmer Spine Interbody Fusion and Vertebral Body Replacement (VBR) systems are spinal implants designed to replace collapsed/damaged vertebral bodies or facilitate fusion in the cervical, thoracic, and lumbar spine. Implants are placed via anterior, posterior, or transforaminal surgical approaches by surgeons. Devices restore biomechanical integrity of the spinal column; used with autogenous bone graft. This submission updates labeling to include MRI Conditional status. No changes to device design, materials, or surgical technique. Benefit: restoration of spinal stability and support for fusion in patients with DDD or vertebral trauma.

Clinical Evidence

No clinical data provided. Bench testing only. Testing performed to assess MRI compatibility per ASTM F2052 (displacement force), ASTM F2119 (image artifacts), ASTM F2182 (RF-induced heating), and ASTM F2213 (magnetically induced torque).

Technological Characteristics

Implants manufactured from Ti-6Al-4V ELI titanium alloy or PEEK OPTIMA with tantalum markers. InFix system includes optional UHMWPE endcap. Instrumentation materials: surgical grade stainless steel, aluminum, silicone rubber, Radel, AlTiN/TiN PVD coatings, nylon. Single-use implants; terminally sterilized (except InFix, which is non-sterile).

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) (discogenic back pain with disc degeneration) or vertebral body collapse/instability due to tumor or trauma. DDD patients may have up to Grade 1 spondylolisthesis or retrolisthesis. Cervical indications (BAK/C) for DDD with radicular symptoms. Requires 6 months non-operative treatment for DDD. Contraindications: none explicitly listed beyond skeletal maturity requirements.

Regulatory Classification

Identification

An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.

Special Controls

*Classification.* (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval. (c) *Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

The Zimmer Spine Interbody Fusion and Vertebral Body Replacement Device Systems are intended for use in the cervical, thoracic and/or lumbar spine to mitigate and/or replace the disc space. The interbody fusion devices are intended for use with autogenous bone graft in patient with degenerative disc disease (DDD); defined as discogenic back pain and degeneration of the disc space. The vertebral body replacement (VBR) devices are intended to replace a collapsed, damaged or unstable vertebral body. VBR devices are designed to restore the biomechanical integrity of the anterior, middle and posterior spinal column in the absence of fusion for a prolonged period.

{9}------------------------------------------------

The subject devices are to be implanted by either an anterior approach or a posterior approach or a transforaminal approach per the indications for use and/or the instructions of the surgical technique quide(s). The BAK devices are also indicated for laparoscopic implantation, per the device indications for use.

The Zimmer Spine Interbody Fusion and Vertebral Body Replacement Device System implants are manufactured from medical grade Ti-6AI-4V ELI titanium alloy or Polyether ether ketone (PEEK) OPTIMA with tantalum markers. The InFix system allows for the use of an optional Endcap made from Ultra High Molecular Weight Polyethylene (UHMWPE).

System(s) with instrumentation, the instruments are manufactured from one (or more) of the following materials: Surgical Grade Stainless Steel, Aluminum, Silicone Rubber, Radel, AITiN PVD coating, TiN PVD Coating, Nylon.

The subject implants are provided terminally sterilized with the exception of the InFix System, which is provided Non-Sterile. The InFix System must be sterilized by the end-user/healthcare facility prior to use. The subject implants are designed for single-use only. The System(s) instrumentation is provided to the end-user/healthcare facility clean but not sterile.
