Indications for Use
The Zyston Curve Interbody Spacer System is indicated for intervertebral body fusion at one level or two contiguous levels in the lumbar spine from L2 to S1 in patients with degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis at the involved level(s). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies. These patients should be skeletally mature and have had six months of non-operative treatment. The Zyston Curve Interbody Spacer System is designed for use with autograft to facilitate fusion and is intended for use with supplemental fixation systems cleared for use in the lumbar spine. The Zyston Curve Interbody Spacer System may also be implanted using the Accuvision System to provide the surgeon with a minimally invasive approach for posterior or posterolateral spinal surgery.
Device Story
Zyston Curve Interbody Spacer System is a spinal implant for intervertebral body fusion; constructed of PEEK with titanium alloy threaded insert and tantalum radiographic markers. Used in lumbar spine (L2-S1) for DDD patients; requires autograft and supplemental fixation. Implanted by surgeons via open or minimally invasive approach (e.g., Accuvision System). Device provides structural support to facilitate fusion; mechanical performance validated via static/dynamic compression and subsidence testing. Benefits include stabilization of spinal segment in patients with discogenic back pain.
Clinical Evidence
Bench testing only. Mechanical performance validated through static axial compression, dynamic axial compression, static compression-shear, dynamic compression-shear, and subsidence testing in accordance with ASTM F-2077 and ASTM F-2267 standards.
Technological Characteristics
Materials: Medical grade PEEK, titanium alloy (threaded insert), tantalum (radiographic markers). Design: Intervertebral body fusion spacer. Standards: ASTM F-2077 (static/dynamic axial compression, static/dynamic compression-shear, subsidence), ASTM F-2267 (subsidence).
Indications for Use
Indicated for skeletally mature patients with degenerative disc disease (DDD) and up to Grade 1 spondylolisthesis at one or two contiguous lumbar levels (L2-S1) who have failed six months of 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.
