The aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X) is intended for interbody fusion in skeletally mature patients and is to be used with supplemental fixation instrumentation cleared for use in the lumbar spine. The aprevo® anterior lumbar interbody fusion device with interfixation is indicated for use as an adjunct to fusion at one or more levels of the lumbar spine in patients having an ODI >40 and diagnosed with severe symptomatic adult spinal deformity (ASD) conditions. These patients should have had six months of non-operative treatment. The devices are intended to be used with autograft and/or allogenic bone graft comprised of cancellous bone and/or cortico-cancellous bone. These implants may be implanted via a variety of open or minimally invasive approaches. ALIF-X implants are intended for standalone use at one or two levels of the spine when used with the screws that accompany the implant and with implants less than or equal to 20 degrees of lordosis. At more than two levels or with implants greater than 20 degrees of lordosis, ALIF-X is intended to be used with the screws that accompany each implant and with supplemental fixation. When used at more than one level in patients with degenerative scoliosis and/or sagittal deformity, the aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X) must be used with a supplemental internal spinal fixation system (e.g., pedicle screw system) cleared by the FDA for use in the lumbar spine in addition to the integrated screws.

The aprevo® anterior lumbar interbody fusion device with interfixation is designed to stabilize the lumbar spinal column and facilitate fusion. The personalized aprevo® device incorporates patient specific features to allow the surgeon to tailor the procedure to the individual needs of the patient and includes an aperture intended for the packing of bone graft. The individualized surgical correction plan and device configurations are developed using patient CT scans. The aprevo® devices are manufactured from titanium alloy (Ti-6Al-4V) per ASTM F3001, while the screws are machined from material per ASTM F136. The devices are accompanied by an inserter instrument which facilitates the placement of the interbodies. Both the interbody devices and instrument are provided as single use, sterile-packed product to the end user. The purpose of this 510(k) is to modify the indications for use of the subject device to include standalone indications.

I am sorry, but the provided text does not contain information about acceptance criteria or a study proving that a device meets such criteria. The document is an FDA 510(k) clearance letter and a 510(k) Summary for a medical device called "aprevo® anterior lumbar interbody fusion device with interfixation."

This type of document primarily focuses on establishing substantial equivalence to previously cleared devices, rather than detailing specific performance acceptance criteria and studies demonstrating adherence to those criteria for software or AI/ML components. The text describes the device, its intended use, comparison to predicate devices, and regulatory classification. It does not mention any AI/ML components, software, or studies evaluating algorithm performance, human reader improvement with AI assistance, or related aspects.

Therefore, I cannot fulfill your request for information about acceptance criteria and a study that proves the device meets them based on the provided text.

The aprevo® anterior lumbar interbody fusion device with interfixation is intended to be used with the screws that accompany each implant and with supplemental fixation.

The aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X) is indicated for use at one or more levels of the lumbosacral spine as an adjunct to fusion in patients with the following indications: degenerative disc disease (DDD), disc herniation (with mvelopathy and/or radiculopathy), spondylolisthesis, deformity (degenerative scoliosis or kyphosis), spinal stenosis, and failed previous fusion (pseudarthrosis). DDD is defined as discogenic back pain with degeneration of the disc as confirmed by history and radiographic studies. These patients should be skeletally mature and have had at least six (6) months of non-operative treatment. aprevo® lumbar interbody fusion devices are to be filled with autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone. These devices are intended to be used with supplemental fixation systems that have been cleared for use in the thoracolumbosacral spine (e.g., posterior pedicle screw and rod systems). These implants may be implanted via a variety of open or minimally invasive approaches. The aprevo® anterior lumbar interbody fusion device with interfixation is intended to be used with the screws that accompany each implant and with supplemental fixation.

The aprevo® anterior lumbar interbody fusion device with fixation (ALIF-X is) designed to stabilize the lumbar spinal column and promote fusion. The personalized aprevo® interbodies incorporate patient specific features to allow the surgeon to tailor the deformity correction to the individual needs of the patient and include an aperture intended for the packing of bone graft. The aprevo® ALIF-X device is accompanied by three screws designed to be used to provide fixation.

The aprevo® ALIF-X interbodies are additively manufactured from Ti-6A1-4V ELI titanium alloy per ASTM F3001, while the screws are machined from material per ASTM F136. The devices are accompanied by an inserter instrument which facilitates the placement of the interbodies. Both the interbody devices and instrument are provided as single use, sterile-packed product to the end user.

The provided text is a 510(k) Summary for the aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X). It outlines the device, its intended use, and a summary of technological similarities and differences to a predicate device.

However, the document does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of AI/ML performance, such as diagnostic accuracy, sensitivity, or specificity. The "Performance Testing Summary" section refers to mechanical testing standards (ASTM F2077 and ASTM F3001) for physical properties of the implant, not clinical or AI/ML performance.

Therefore, I cannot provide the requested information from the given text. The questions about test sets, data provenance, expert ground truth, adjudication methods, MRMC studies, standalone performance, and training set details are not addressed in this filing, as they are not relevant to the type of device being described (a physical spinal implant, not an AI/ML-driven diagnostic or therapeutic tool).

The provided text is a 510(k) summary for a medical device called "aprevo® anterior lumbar interbody fusion device with interfixation (ALIF-X)". It describes the device, its intended use, and the performance testing conducted to demonstrate its substantial equivalence to a predicate device.

However, the document does not contain information about a study proving the device meets acceptance criteria in the context of an AI/ML device assessment, nor does it discuss clinical performance metrics, sample sizes for test sets, data provenance, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance.

The "performance data" section only lists various mechanical tests (static axial compression, compression shear, dynamic axial compression, dynamic compression shear, subsidence, static screw pushout testing) and a "Clinical Evaluation of Interfixated Implant Usability, Fit and Accuracy." These are typical engineering and usability tests for an implantable medical device, not a study of AI/ML algorithm performance. The conclusion states that the mechanical performance is sufficient for its intended use and substantially equivalent to predicate devices.

Therefore, I cannot provide the requested information, which pertains to the acceptance criteria and study details for an AI/ML device, based on the given FDA 510(k) summary for a physical medical implant.
