A-Link Z anterior cages are indicated for intervertebral body fusion of the spine in skeletally mature patients who have had at least six months of non-operative treatment. The device systems are designed for use with allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and/or autograft to facilitate fusion. One device is used per intervertebral body space. A-Link Z anterior cages are 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. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. A-Link Z 2-screw anterior cages may be used as a stand alone device only when two (2) vertebral body bone screws are used. A-Link Z 4-screw anterior cages may be used as a stand alone device only when at least two (2) vertebral body bone screws are inserted in the two medial fixation holes with one inferior and one superior screw trajectory. If the physician chooses to use A-Link Z anterior cages with fewer than two (2) screws in the two medial fixation holes with one inferior and one superior screw trajectory, then an additional supplemental spinal fixation system cleared for use in the lumbosacral spine must be used.

A-Link Z anterolateral cages are indicated for intervertebral body fusion of the spine in skeletally mature patients who have had at least six months of non-operative treatment. The device systems are designed for use with allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and/or autograft to facilitate fusion. One device is used per intervertebral body space. A-Link Z anterolateral cages are 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. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. A-Link Z anterolateral cages are intended to be used with supplemental spinal fixation system cleared for use in the lumbosacral spine.

A-Link Z lateral cages are indicated for intervertebral body fusion of the spine in skeletally mature patients who have had at least six months of non-operative treatment. The device systems are designed for use with allogenic bone graft comprised of cancellous and/or corticocancellous bone graft and/or autograft to facilitate fusion. One device is used per intervertebral body space. A-Link Z lateral cages are 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. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. A-Link Z lateral cages are intended to be used with supplemental spinal fixation system cleared for use in the lumbosacral spine.

A-Link Z consists of six models of intervertebral body fusion devices intended for anterior, anterolateral, or lateral lumbar interbody fusion. The A-Link Z Modular Cages, A-Link Z Standard Cages, A-Link Z FRA Cages, and A-Link Z Open Cages are intended for anterior approach. A-Link Z AL Cages are intended for anterolateral approach. A-Link Z Lateral Cages are intended for lateral approach. The devices are intended to improve stability of the spine while supporting fusion. The A-Link Z constructs are intended for use at either one level or two contiguous levels in the lumbar spine, from L2 to S1. Components are offered in different shapes and sizes to meet the requirements of the individual patient anatomy. A-Link Z devices are made from titanium alloy (Ti-6Al-4V ELI) per ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications and ASTM F3001 Standard Specification for Additive Manufacturing Titanium-6 Aluminum-4 Vanadium ELI 5Extra Low Interstitial) with Powder Bed Fusion, and an optional interbody component composed of polyetheretherketone (PEEK) per ASTM F2026 Standard Specification for Polyetheretherketone (PEEK) Polymers for Surgical Implant Applications with tantalum markers per ASTM F560 Standard Specification for Unalloyed Tantalum for Surgical Implant Applications.

This FDA 510(k) summary (K201671) describes a spinal intervertebral body fusion device (A-Link Z), not an AI-powered medical device. Therefore, the document does not contain the information requested in the prompt regarding acceptance criteria, study details for AI performance, sample sizes for training/test sets, expert adjudication, MRMC studies, or ground truth establishment for an AI algorithm.

The document focuses on demonstrating substantial equivalence to predicate devices through non-clinical testing (biocompatibility and mechanical performance testing), as is typical for traditional medical device clearances under the 510(k) pathway. There is no mention of an algorithm, image analysis, or any form of AI component.

Therefore, I cannot provide the requested table and study details as the input document does not pertain to an AI device.
