The FlareHawk Interbody Fusion System is indicated for spinal intervertebral body fusion with autogenous bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone in skeletally mature individuals with degenerative disc disease (DDD) at one or two contiguous levels from L2 to S1, following discectomy. DDD is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These patients should have at least six (6) months of non-operative treatment. Additionally, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). FlareHawk system spacers are intended to be used with supplemental fixation instrumentation, which has been cleared for use in the lumbar spine.

FlareHawk Interbody Fusion System is an expandable lumbar intervertebral body fusion device intended for use in the lumbosacral spine from L2 to S1. The FlareHawk interbody fusion device consists of a shell and a shim component that are offered in various lengths, heights, and lordotic angles to accommodate variations in patient anatomy. When the FlareHawk device is deployed within the intervertebral disc space, the shell and shim components lock together to create a complete implant construct to provide structural stability for interbody fusion. The final dimensions of the deployed device construct are determined by the dimensions of the selected shell and shim. Once implanted, the FlareHawk interbody fusion device is designed to restore intervertebral disc height, provide anterior column support, and maintain structural stability of the motion segment to facilitate intervertebral body fusion.

The FlareHawk interbody fusion device is intended to be used with autogenous bone graft and/or allogeneic bone graft composed of cancellous and/or corticocancellous bone, and with supplemental fixation instrumentation that has been cleared for use in the lumbar spine.

The FlareHawk Interbody Fusion System includes manual surgical instruments for delivery of the implant device and for disc preparation.

The provided FDA 510(k) clearance letter for the FlareHawk Interbody Fusion System does not contain any information about acceptance criteria or a study proving that the device meets specific performance criteria related to AI or diagnostic accuracy.

This document is for an Intervertebral Body Fusion Device (a spinal implant), which is a physical medical device, not a software-based diagnostic AI device. Therefore, the questions posed in the prompt related to AI performance, ground truth establishment, expert consensus, MRMC studies, and training/test set sizes are not applicable to the information provided in this 510(k) summary.

The "studies" mentioned in the document are non-clinical bench performance tests primarily related to MRI compatibility of the implant, such as:

• Measurement of magnetically induced displacement force
• Measurement of magnetically induced torque
• Evaluation of MR image artifacts
• Measurement of radio frequency induced heating

These tests confirm the physical properties and safety of the implant in an MRI environment, not the diagnostic or analytical performance of an AI algorithm.

Therefore, I cannot provide the requested table or answer the specific questions about acceptance criteria and a study proving device performance in the context of an AI device, as the provided text pertains to a physical orthopedic implant.
