Indications for Use
The Stryker Spine Tritanium® PL Cage is an intervertebral body fusion device indicated for use with autograft and/or allogenic bone graft comprised of cancellous and/or corticocancellous bone graft when used as an adjunct to fusion 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. Additionally, the Tritanium® PL Cage can be used as an adjunct to fusion in patients diagnosed with degenerative scoliosis. The Tritanium® PL Cage is to be implanted via a posterior approach. The Tritanium® PL Cage is intended to be used with supplemental spinal fixation systems that have been cleared for use in the lumbosacral spine.
Device Story
Tritanium® PL Cage is a hollow, rectangular intervertebral body fusion implant; constructed from Ti-6Al-4V titanium alloy using Laser Rapid Manufacturing (LRM) to create solid and porous structures (Tritanium® In-Growth Technology). Implant features serrated superior/inferior porous surfaces for fixation; ergonomically shaped anterior edge; flat posterior edge. Available in various lengths, heights, widths, and lordotic angles. Implanted via posterior approach by surgeons to facilitate spinal fusion in the lumbosacral spine. Used as an adjunct to supplemental spinal fixation systems. Provides structural support to the intervertebral space during the fusion process; porous surface promotes bone in-growth.
Clinical Evidence
No clinical data. Bench testing only: Bacterial endotoxin testing (BET) per ANSI/AAMI ST72:2011 to ensure < 20EU/Device. No additional mechanical testing performed due to lack of changes in fit, form, or function compared to predicate.
Technological Characteristics
Material: Ti-6Al-4V titanium alloy (ASTM F1472-08). Manufacturing: Laser Rapid Manufacturing (LRM) for porous/solid structure. Form factor: Hollow, rectangular cage with serrated surfaces. Sterilization: Provided sterile.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels (L2-S1) or degenerative scoliosis. DDD patients may have up to Grade I spondylolisthesis and must have failed six months of nonoperative therapy. Used with autograft/allogenic bone graft and supplemental 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.
