Intended Use
Solar-S™ (Standalone, With Integrated Fixation) and Solar-A™ (Non-Standalone, With Integrated Fixation) The Solar-S™ (Standalone) and Solar-A™ (Non-Standalone) are lumbar interbody fusion devices intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L2-S1). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. In addition, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. Solar-S™ and Solar-A™ ALIF Spacers are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. • Solar-S™ Used With Screws or Tusks: When used with three (3) screws, interbody devices with a lordotic angle ≤ 20° can be used as standalone interbody fusion devices at 1 or 2 contiguous levels. When used with three (3) tusks, interbody devices must always be used with supplemental fixation and may be used at 1 or 2 levels. Hyperlordotic interbody devices (>20° lordosis) used with screws must always be used with supplemental fixation and may be used at 1 or 2 levels. • Solar-A™: These devices are intended to be used with supplemental fixation systems that have been cleared for use in the lumbosacral spine (e.g., posterior pedicle screw and rod systems, anterior plate systems, anterior screw and rod systems). Hyperlordotic interbody devices (≥20° lordosis) must be used with at least anterior supplemental fixation. Solar-M™ ALIF Spacers (Without Integrated Fixation) Solar-M™ ALIF Spacers are lumbar interbody fusion devices indicated at one or more levels of the thoracic spine (T1-T12), thoracolumbar junction (T12-L1), or lumbosacral spine (L1-S1) as an adjunct to fusion in patients with the following indications: degenerative disc disease (DDD), disc herniation (with myelopathy and/or radiculopathy), spondylolilsthesis, deformity (degenerative scoliosis or kyphosis), spinal stenosis, and failed previous fusion (pseudarthrosis). DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should be skeletally mature and have has at least six (6) months of non-operative treatment. Solar-M™ ALIF Spacers are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. These devices are intended to be used with supplemental fixation systems that have been cleared for use in the thoracolumbosacral spine (e.g., posterior pedicle screw and rod systems, anterior plate systems, anterior screw and rod systems). Hyperlordotic interbody devices (≥20° lordosis) must be used with at least anterior supplemental fixation.
Device Story
Solar™ Lumbar Interbody Fusion System; additively manufactured titanium interbody spacers for anterior lumbar fusion. Configurations include standalone (Solar-S), anterolateral (Solar-A), and monolithic (Solar-M). Spacers feature porous endplates to mitigate subsidence/expulsion and central aperture for bone graft. Solar-S and Solar-A utilize integrated fixation (Titanium-6AL-4V ELI screws or unalloyed titanium tusks). Used by surgeons in clinical settings to facilitate spinal fusion; provides structural support to disc space. Output is physical stabilization of vertebral segments; clinical decision-making relies on surgeon assessment of patient anatomy and fusion requirements. Benefits include stabilization of spinal segments and promotion of arthrodesis.
Clinical Evidence
Bench testing only. Performed dynamic compression, static/dynamic compression shear, and axial tusk pushout testing per ASTM F2077 to demonstrate mechanical equivalence.
Technological Characteristics
Additively manufactured unalloyed titanium (Puri-Ti™) spacers. Integrated fixation screws: Titanium-6AL-4V ELI (ASTM F136). Integrated fixation tusks: unalloyed titanium. Features porous surface endplates and central bone graft aperture. Mechanical stabilization via interbody spacer and integrated fixation.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) at 1-2 contiguous levels (L2-S1) or thoracic/thoracolumbar/lumbosacral levels (T1-S1) for Solar-M. Includes patients with disc herniation, spondylolisthesis, retrolisthesis, deformity (scoliosis/kyphosis), spinal stenosis, or failed previous fusion. Requires 6 months 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.
