Pedicle Screw System: The MASADA Modular Spinal Fixation System is intended for immobilization and stabilization of the posterior, non-cervical spine in skeletally mature patients as an adjunct to fusion for the following indications: degenerative disc disease ( defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (i.e., fracture or dislocation), spinal stenosis, curvatures (i.e., scoliosis, kyphosis, or lordosis), tumor, pseudoarthrosis, and/or failed previous fusion.

When used for posterior non-cervical pedicle screw fixation in pediatric patients, the MASADA pedicle screw implants are indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis. The MASADA pedicle screw is intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.

Navigated Instrument System: The MASADA navigated instruments are intended to be used in the preparation and placement of MASADA screws during spinal surgery to assist the surgeon in precisely locating anatomical structures in either open or minimally invasive procedures. These instruments are designed for use with the Medtronic StealthStation® System, which is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as a skull, a long bone, or vertebra, can be identified relative to a CT or MR based model, fluoroscopy images, or digitized landmarks of the anatomy. Refer to the Astura Navigated Instrument system Instructions For Use (INS-00006) regarding the use of these instruments.

Sublaminar Band System: The MASADA sublaminar band is a temporary implant for use in orthopedic surgery. The band system is intended to provide temporary stabilization as a bone anchor during the development of solid bony fusion and aid in the repair of bone fractures. The indications for use include the following applications: - Spinal trauma surgery, used in sublaminar or facet wiring techniques. - Spinal reconstructive surgery, incorporated into constructs for the purpose of correction of spinal deformities such as idiopathic and neuromuscular scoliosis in patients 8 years of age or older, adult scoliosis, kyphosis and spondylolisthesis. - Spinal degenerative surgery, as an adjunct to spinal fusions. The MASADA sublaminar band may also be used in conjunction with other medical grade implants made of similar metals whenever "wiring" may help secure the attachment of the other implants.

The MASADA Modular Spinal Fixation System is intended for immobilization and stabilization of the posterior, non-cervical spine in skeletally mature patients as an adjunct to fusion. The system is composed of modular polyaxial screws, monoaxial screws, rods, cross connectors, rod connectors, sublaminar band cerclages, band connectors, and hooks. The system is supported by a comprehensive set of instruments to install the implants within the system. All implant components are manufactured from the materials listed in the table below.

The provided text is an FDA 510(k) clearance letter for a medical device called the "MASADA Modular Spinal Fixation System." This document is a regulatory approval, not a scientific study report describing the performance of an AI/ML device. Therefore, it does not contain the information requested regarding acceptance criteria, device performance metrics, sample sizes, ground truth establishment, expert qualifications, or MRMC studies for an AI/ML system.

The "Non-clinical Test Summary" explicitly states: "An engineering analysis determined that no new worst case conditions have been introduced since the previously cleared submission (K231694)." and the "Clinical Test Summary" explicitly states: "No clinical studies were performed."

This means the clearance was based on substantial equivalence to predicate devices through design, materials, and engineering analysis, rather than new performance data from a clinical or AI/ML-specific study.

Therefore, I cannot provide the requested table and details about acceptance criteria and study findings for an AI/ML device based on the given input.
