When used as a cervical intervertebral body fusion device, the Aleutian implants are indicated for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients. Cervical IBF implants are intended for use at one level in the cervical spine, from C2 to T1, for the treatment of cervical disc disease (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). The cervical device is intended to be used in patients who have had six weeks of non-operative treatment.

When used as a lumbar intervertebral body fusion device, the Aleutian implants are indicated for spinal fusion procedures to be used with autogenous bone graft in skeletally mature patients. The lumbar IBF implants are intended for use at either one levels in the lumbar spine, from L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The lumbar device is intended to be used in patients who have had six months of non-operative treatment.

When used as vertebral body replacement devices the Aleutian implants are indicated for use in the thoracolumbar spine (T1 to L5) for partial replacement (i.e., partial vertebrectomy) of a diseased vertebral body, resected or excised for the treatment of tumors or trauma/fracture in order to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The Aleutian implants are designed to restore the biomechanical integrity of the anterior, middle, and posterior spinal column even in the absence of fusion for a prolonged period.

For all the above indications the Aleutian implants are intended to be used with supplemental internal fixation appropriate for the implanted level, including K2M Pedicle Screw and Hook Systems, and K2M Spinal Plate Systems.

The Aleutian Spinal System consists of a hollow tube or horseshoe-shaped structures. The devices are available in a variety of different sizes and heights to match more closely the patient's anatomy. The ends of the implants have machined teeth which are designed to engage with the vertebral body end plates.

Materials: The implants are manufactured from Medical Grade PEEK per ASTM F2026. Tantalum beads/ rods are to be made of Grade UNS R05200, UNS R05400 according to ASTM F560.

Function: The system functions as an intervertebral body fusion device to provide support and stabilization of the cervical and lumbar segments of the spine.

The purpose of this submission is to incorporate titanium implants into the system.

The provided text is a 510(k) summary for the Aleutian IBF System, which describes the device, its intended use, and its substantial equivalence to predicate devices. It does not contain any information about acceptance criteria, study data, sample sizes, ground truth establishment, or expert involvement.

Therefore, I cannot provide the requested table and study details. The document explicitly states:

"An engineering rationale determined that the proposed spacers do not represent a new worst case for testing and are therefore considered substantially equivalent to the predicates referenced."

This indicates that the submission relies on an engineering rationale and comparison to previously cleared devices rather than a new standalone study with performance metrics in the format requested.
