Indications for Use

The Stryker Spine AVS PL PEEK Spacers are intervertebral body fusion devices indicated for use with autogenous bone graft in patients with degenerative disc disease (DDD) at one level or two contiguous levels from L2 to S1. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The DDD patients may also have up to Grade I spondylolisthesis at the involved level(s). These patients should be skeletally mature and have six months of nonoperative therapy. The AVS PL PEEK Spacers are to be implanted via posterior approach. The AVS PL PEEK Spacers are intended to be used with supplemental spinal fixation systems that have been cleared for use in the lumbosacral spine (i.e., posterior pedicle screw and rod systems).

Device Story

AVS PL PEEK Spacers are rectangular, hollow-frame intervertebral body fusion implants with lateral fenestrations; designed for posterior approach spinal fusion. Implants feature Tantalum marker pins for radiographic visualization; available in various heights (6-13mm), lengths (30-33mm), and wedge angles (0° or 4°). Used by surgeons in clinical settings to facilitate fusion in patients with degenerative disc disease. Device acts as a structural spacer to maintain disc space height while bone graft promotes fusion; requires concurrent use of cleared supplemental posterior pedicle screw and rod fixation systems. Benefits include stabilization of spinal segments and support for arthrodesis.

Clinical Evidence

Bench testing only. No clinical data provided. Performance was evaluated in compliance with the FDA's 'Class II Special Controls Guidance Document: Intervertebral Body Fusion Device' to demonstrate substantial equivalence.

Technological Characteristics

Materials: PEEK (Polyetheretherketone) and Tantalum (marker pins). Form factor: Rectangular, hollow-frame with lateral fenestrations. Dimensions: 6-13mm height, 30-33mm length, 11mm width; 0° and 4° wedge options. Principle: Intervertebral body fusion spacer. Sterilization: Not specified.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, including those with up to Grade I spondylolisthesis, who have failed six months of nonoperative therapy. Must be used with autogenous bone graft and supplemental posterior spinal fixation.

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.
