Indications for Use
The VIRTU Lumbar Spacer System is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels in the lumbar spine (L2-S1) with up to Grade 1 spondylolisthesis or retrolisthessis 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 the involved level may be treated with the VIRTU Lumbar Spacer System. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the VIRTU PLIF/TLIF System. The VIRTU Lumbar Spacer System is designed for use with autogenous bone graft to facilitate fusion. The system is also intended to be used with supplemental internal spinal fixation systems that are cleared by the FDA for use in the lumbar spine.
Device Story
VIRTU Lumbar Spacer System consists of implants, trials, and instruments for spinal fusion. Implants are placed via posterior (PLIF) or transforaminal (TLIF) approach to restore disc height and facilitate fusion. Used with autogenous bone graft and supplemental internal spinal fixation systems cleared for lumbar use. Operated by surgeons in clinical settings. Device provides structural support to the intervertebral space; benefits patients by stabilizing the spine and promoting fusion in cases of degenerative disc disease.
Clinical Evidence
Bench testing only. Testing included static axial compression (modified ASTM 2077-11), dynamic axial compression (ASTM 2077-11), expulsion (ASTM Draft Standard F-04.25.02.02), and subsidence (ASTM F2267). Results demonstrate mechanical strength sufficient for intended use.
Technological Characteristics
Implants manufactured from PEEK (ASTM F2026) and tantalum (ASTM F560). Device functions as an intervertebral body fusion spacer. Mechanical design supports axial loading and provides structural stability for spinal fusion. No software or electronic components.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous lumbar levels (L2-S1) with up to Grade 1 spondylolisthesis or retrolisthesis. Includes patients with prior non-fusion spinal surgery at the involved level. Requires at least 6 months of failed non-operative treatment.
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.
