Indications for Use
The NEXXT MATRIXX® Stand Alone ALIF System is a stand-alone anterior lumbar interbody fusion system intended for use as an adjunct to fusion at one or two contiguous levels (L2-S1) in skeletally mature patients for the treatment of degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies). These patients may also have up to Grade I spondylolisthesis at the involved levels and should have received at least six months of nonoperative treatment with the device. The NEXXT MATRIXX® Stand Alone ALIF System is to be used with autograft bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone. Hyperlordotic interbody devices (>20° lordosis) must be used with supplemental fixation (e.g. posterior fixation). Each interbody fusion device having a lordotic angle 20º or less is intended to be used with the bone screws provided and requires no additional fixation.
Device Story
NEXXT MATRIXX® Stand Alone ALIF System is an additively manufactured spinal implant system; provides surgical stabilization of the spine; consists of structural interbody cages and fixation screws. Interbody features roughened surface (~7µm) and geometric lattices (300-700µm pores) to facilitate fusion; includes vertical cavity for bone graft packing. Preassembled turn-lock mechanisms secure screws to interbody. Used by surgeons in clinical settings for anterior lumbar interbody fusion. Hyperlordotic devices (>20°) require supplemental posterior fixation; devices ≤20° function as stand-alone systems with provided screws. System provides mechanical stability to the intervertebral space; promotes fusion via bone graft containment; benefits patients by addressing discogenic pain and spinal instability.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing including subsidence, static and dynamic compression, static and dynamic compression shear (ASTM F2267, ASTM F2077), expulsion, and screw pushout testing.
Technological Characteristics
Additively manufactured Ti-6Al-4V ELI titanium alloy (ASTM F3001) interbody; Ti-6Al-4V ELI (ASTM F136) fixation screws/turn-lock components. Features roughened surface (~7µm) and 300-700µm lattice pores. Stand-alone design with integrated screw-locking mechanism. Dimensions comparable to predicate systems.
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (discogenic back pain) at one or two contiguous levels (L2-S1), including those with up to Grade I spondylolisthesis or retrolisthesis, who have failed at least six months of nonoperative 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.
