Magnum+ is a stand alone device intended to be used with bone screws. If the physician chooses to use fewer than the maximum number of screws accommodated by the device, then additional supplemental fixation, which has been cleared by the FDA for use in the lumbar spine, must be used to augment stability.

When used as a vertebral body replacement:
When used as a vertebral body replacement, the device is intended for use in the thoracic and/or thoracolumbar spine (T1-L5) to replace a collapsed, damaged, or unstable vertebral body resected or excised (i.e., partial or total vertebrectomy procedures) due to tumor or trauma (i.e., fracture).
The interior of the spacer can be packed with allograft or autograft.

When used as an intervertebral body fusion device:
Lucent Magnum+ is an intervertebral body fusion device intended for spinal fusion procedures at one or two contiguous levels (L2-S1) in skeletally mature patients with degenerative disc disease (DDD). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis or retrolisthesis at the involved levels. These patients may have had a previous non-fusion spinal surgery at the involved spinal level(s).
This device is intended to be used with autogenous bone graft. Patients must have undergone a regimen of at least six (6) months of non-operative treatment prior to being treated with the device.

Spinal Elements' Lucent Magnum+ device is composed of a main device body (spacer) and fixation screws. The spacer is generally oval-shaped with various holes throughout its geometry. The superior and inferior surfaces of the spacer have engagement members to help prevent migration once surgically positioned. The spacer has holes through it that allow for the passage of bone screws that affix to bone to help prevent migration.
Devices are available in a multitude of sizes. The spacer may be made from titanium alloy (Ti-6Al-4V) conforming to ASTM F 136 or ISO 5832-3 or polyetheretherketone (PEEK-OPTIMA LTI, provided by Invibio) conforming to ASTM F 2026. Because PEEK is radiolucent, tantalum (per ASTM F 560) pins are embedded into PEEK spacers to serve as markers for radiographic visualization of spacer orientation. Screws are manufactured from titanium alloy (Ti-6A1-4V) conforming to ASTM F 136 or ISO 5832-3. All implants are intended for single use only and should not be reused under any circumstances. Components from this system should not be used in conjunction with components from other systems.

This document is a 510(k) Premarket Notification for a medical device called Lucent® Magnum+. It describes the device, its intended uses, and claims substantial equivalence to previously cleared devices.

There is no information in this document about acceptance criteria, device performance metrics, or a study to prove the device meets acceptance criteria.

The document is a regulatory submission for premarket clearance, which typically focuses on demonstrating equivalence to existing legally marketed devices rather than presenting detailed performance studies against specific acceptance criteria for a novel AI device. The device itself is a physical intervertebral body fusion device and not an AI/ML powered device. Therefore, a study proving device performance against acceptance criteria as might be done for software or AI medical devices is not applicable here.

The provided text describes a medical device, the Lucent® Magnum+, and its intended use, but it does not contain any information about acceptance criteria or a study proving the device meets any specific performance criteria.

The document is a 510(k) summary for a medical device cleared by the FDA. Such documents primarily focus on demonstrating substantial equivalence to a legally marketed predicate device, rather than detailed performance studies with acceptance criteria.

Therefore, I cannot provide the requested information. The text does not include:

1. A table of acceptance criteria and reported device performance.
2. Sample size used for a test set or its data provenance.
3. Number or qualifications of experts used to establish ground truth.
4. Adjudication method.
5. Information about a multi-reader multi-case (MRMC) comparative effectiveness study.
6. Information about a standalone performance study.
7. The type of ground truth used.
8. Sample size for a training set.
9. How ground truth for a training set was established.

The document primarily focuses on:

• Device Description: What the device is made of and its general shape.
• Intended Use: The medical conditions and anatomical locations for which the device is designed (e.g., vertebral body replacement, intervertebral body fusion).
• Substantial Equivalence: Listing predicate devices to which the Lucent® Magnum+ is considered equivalent based on indications for use, design, function, and materials.

In the context of 510(k) clearance, the "study" is often a comparison to a predicate device, focusing on equivalence rather than independent performance metrics against predefined acceptance criteria.

The Lucent® Magnum device is a medical implant, and its acceptance criteria are based on mechanical performance demonstrating substantial equivalence to predicate devices, rather than a clinical study with human readers or AI.

1. Table of Acceptance Criteria and the Reported Device Performance:

2. Sample size used for the test set and the data provenance:

• Sample Size: Not applicable. The "study" referenced is mechanical testing, not a clinical trial with a test set of patient data.
• Data Provenance: Not applicable.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not applicable as the assessment is based on mechanical testing and comparison to predicate devices, not expert human interpretation of medical data.

4. Adjudication method for the test set:

• Not applicable.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

• No MRMC study was performed or is relevant to this device. This device is an implant, not an AI-powered diagnostic tool.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• Not applicable. This is not an AI algorithm.

7. The type of ground truth used:

• The "ground truth" for the Lucent® Magnum's acceptance is based on established engineering principles and benchmarks for mechanical strength and durability of similar intervertebral body fusion devices, as demonstrated through mechanical testing. The comparison against legally marketed predicate devices serves as the standard for substantial equivalence.

8. The sample size for the training set:

• Not applicable. This is not an AI device that requires a training set.

9. How the ground truth for the training set was established:

• Not applicable.
