Indications for Use
IMPIX-C Cervical Interbody Device is indicated for intervertebral body fusion in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine at one disc level from C3-C7. DDD is defined as discogenic pain with degeneration of the disc confirmed by history and radiographic studies. This device is to be used with autogenous bone graft. IMPIX-C Cervical Interbody Device is to be used with supplemental fixation. Patients should have at least six (6) weeks of non-operative treatment prior to treatment with an intervertebral cage. IMPIX-L Lumbar Interbody Device is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels from L2-S1. DDD is defined as discogenic back pain with degeneration of the disc confirmed by patient history and radiographic studies. These DDD patients may also have up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). This device is to be used with autogenous bone graft. IMPIX-L Lumbar Interbody Device is to be used with supplemental fixation. Patients should have at least six (6) months of non-operative treatment prior to treatment with an intervertebral cage.
Device Story
IMPIX Interbody Devices are spinal implants designed for intervertebral fusion. Cervical version features D-shape, upper surface convexity, anti-migration ridging, and lower pins. Lumbar version is bi-convex with superior/inferior teeth for anchorage. Both devices are hollow to allow packing with autogenous bone graft and feature lateral holes for bone ingrowth. Implants are available in various sizes to accommodate patient morphology. Used by surgeons in clinical settings to stabilize spinal segments in patients with degenerative disc disease. Output is mechanical stabilization of the disc space; facilitates fusion; reduces discogenic pain.
Clinical Evidence
Bench testing only. Mechanical strength testing performed according to ASTM F2077.
Technological Characteristics
Machined from PEEK OPTIMA LT1. Cervical device: D-shape, convex upper surface, anti-migration ridges, lower pins. Lumbar device: bi-convex, superior/inferior teeth. Both are hollow for bone graft packing with lateral holes for bone growth. Mechanical stabilization principle.
Indications for Use
Indicated for intervertebral body fusion in skeletally mature patients with degenerative disc disease (DDD). Cervical (C3-C7, one level) or Lumbar (L2-S1, one or two contiguous levels). Lumbar patients may have up to Grade I spondylolisthesis or retrolisthesis. Requires autogenous bone graft and supplemental fixation. Requires prior non-operative treatment (6 weeks for cervical, 6 months for lumbar).
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.
