Indications for Use

ABTross ALIF Expandable Cage System is indicated for intervertebral body fusion of the spine in skeletally mature patients. The device system is designed for use with bone graft (autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone graft) to facilitate fusion. ABTross ALIF Expandable Cage System is intended for use at either one level or two contiguous levels in the lumbar spine, from L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis or retrolisthesis at the involved level(s). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. Patients should have at least six months of nonoperative treatment prior to treatment with a lumbar intervertebral fusion device. The device is 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, and anterior screw and rod systems). Hyperlordotic interbody devices (≥20° lordosis) must be used with at least anterior supplemental fixation.

Device Story

ABTross ALIF Expandable Cage System is an interbody fusion device for lumbar spine surgery. Device is inserted in unexpanded state via anterior approach; expanded in situ using system-specific height-adjusting driver to tighten internal bolt, which moves guide blocks to push endplates apart. Serrated surfaces contact vertebral endplates to facilitate fusion with bone graft. Used by surgeons in clinical settings; requires supplemental fixation (e.g., pedicle screws, plates). Provides structural support to restore disc height and lordosis; benefits patients by stabilizing spinal segments and promoting fusion in DDD cases. Single-use only; provided sterile.

Clinical Evidence

Bench testing only. No clinical data presented. Mechanical performance validated via static/dynamic compression, static/dynamic shear (ASTM F2077), static expulsion (ASTM draft F-04.25.02.02), and static subsidence (ASTM F2267) testing.

Technological Characteristics

Material: Ti-6Al-4V ELI titanium alloy (ASTM F136). Design: Expandable, lordotic rectangular cylindrical cage. Mechanism: Bolt-driven expansion via height-adjusting driver. Dimensions: 24x32mm to 29x38mm footprint; 6-19mm height range; 8°-30° lordotic angle. Sterilization: Gamma radiation. Single-use.

Indications for Use

Indicated for intervertebral body fusion in skeletally mature patients with degenerative disc disease (DDD) and up to Grade I spondylolisthesis or retrolisthesis at one or two contiguous lumbar levels (L2-S1). Requires six months of failed non-operative treatment. Must be used with supplemental fixation; hyperlordotic devices (≥20°) require anterior supplemental fixation.

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.
