The MediRod Pedicle Screw System, with or without MIS instrumentation, is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of thoracic, lumbar. and sacral spine: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, deformities or curvatures (i.e. scoliosis, kyphosis, spinal tumor, pseudarthrosis and failed previous fusion.

When used for posterior, non-cervical, pedicle screw fixation in pediatric patients, the MediRod Pedicle Screw System implants are indicated as an adjunct to fusion to treat progressive spinal deformities (i.e., scoliosis, kyphosis) including idiopathic scoliosis, neuromuscular scoliosis, and congenital scoliosis. Additionally, the MediRod Pedicle Screw System is intended to treat pediatric patients diagnosed with spondylolisthesis/spondylolysis, fracture caused by tumor and/or trauma, pseudarthrosis, and/or failed previous fusion. This system is intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.

The MediRod Pedicle Screw System is a top loading, multiple component, posterior spinal fixation system which consists of pedicle screws and rods manufactured from titanium alloy. All the components are available in a variety of sizes to match more closely the patient's anatomy.

This document is a 510(k) summary for the "MediRod Pedicle Screw System." It does not describe a study involving device performance metrics, accuracy, or human reader involvement in the context of AI or diagnostic systems. Instead, this document focuses on the mechanical performance testing of a physical medical device (pedicle screws) to demonstrate substantial equivalence to predicate devices for FDA clearance.

Therefore, the requested information regarding acceptance criteria for device performance, sample sizes for test and training sets, expert qualifications, adjudication methods, multi-reader multi-case studies, standalone performance, and ground truth establishment, as typically applied to AI/diagnostic devices, is not available or applicable in this document.

The document states:

• Performance Testing: "Static and dynamic testing of the MediRod Pedicle Screw System was performed in accordance with ASTM F1717 (static and dynamic compression bending, and static torsion testing) and ASTM F1798 (static flexion-extension testing)."
• Conclusion: "Results of the testing demonstrate the substantially equivalent mechanical performance of the subject device."

This indicates that the acceptance criteria are based on meeting the standards set forth in ASTM F1717 and ASTM F1798 for mechanical properties, and the study "proves" the device meets these criteria by demonstrating substantial equivalence in mechanical performance to legally marketed predicate devices. However, no specific numerical acceptance criteria or reported device performance metrics (e.g., accuracy, sensitivity, specificity) are provided in the text.

The PERLA® TL Posterior Osteosynthesis System is intended to provide immobilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: degenerative disc disease; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). When used for posterior noncervical pedicle screw fixation in pediatric patients, the PERLA® TL Posterior Osteosynthesis System is indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis. The PERLA® TL Posterior Osteosynthesis System is intended to be used with autograft and/or allograft. Pediatric pedicle screw fixation is limited to a posterior approach.

The PERLA® TL posterior osteosynthesis system consists of a range of screws, rods, set screws, hooks, rod connectors and cross-connectors. These connecting components can be rigidly locked to the rod in a variety of configurations to be adapted for the individual case. The Perla®TL system is manufactured from medical grade titanium alloy and medical grade cobalt chromium conforming respectively to standards ASTM F136 and ASTM F1537. The PERLA® TL posterior osteosynthesis implants are delivered either non-sterile or sterile (gamma sterilization) and supplied with dedicated surgical instruments. Bacterial endotoxin testing as specified in USP standard is used for pyrogenicity testing to achieve the Endotoxin limit of 20 EU / device. The subject product line extension of the PERLA® TL Posterior Osteosynthesis System manufactured by Spineart (K193396; K203222; K203506) consists of addition of cannulated fenestrated sagittal screws in various sizes and designs to accommodate different patient anatomies or surgeon's techniques.

The provided text describes a 510(k) premarket notification for a medical device called the "PERLA® TL Posterior Osteosynthesis System." This document primarily discusses the substantial equivalence of the new components (cannulated fenestrated sagittal screws) to previously cleared predicate devices based on mechanical performance and design.

However, the provided text DOES NOT contain information regarding the acceptance criteria for an AI/ML powered medical device, nor does it describe a study involving human readers or AI performance metrics such as sensitivity, specificity, or AUC.

The document details the FDA's acknowledgement of the 510(k) submission, the indications for use of the device, and a summary of the technical characteristics and non-clinical performance testing (mechanical testing like static and dynamic compression bending) to demonstrate substantial equivalence to predicate devices. It states:

• "Static compression bending, static torsion and dynamic compression bending testing were conducted in conformance to ASTM F1717-18. Results demonstrated substantial equivalence between Cannulated Fenestrated Sagittal Screw added component to the PerlaⓇTL system and the identified predicate devices."
• "As was established in this submission, the PERLA® TL added components are substantially equivalent and have the same technological characteristics to predicate devices in areas including indications for use, function, material composition, design, range of sizes and mechanical performance."

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves an AI-powered device meets the acceptance criteria based on the provided text. The device described (PERLA® TL Posterior Osteosynthesis System) is a physical medical implant (pedicle screw system), not an AI/ML-powered software device.

The document discusses the substantial equivalence of the PERLA® TL device to legally marketed predicate devices, focusing on:

• Indications for Use: The system is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for various spinal conditions in skeletally mature patients and for adolescent idiopathic scoliosis in pediatric patients.
• Device Description: It consists of screws, rods, set screws, hooks, rod connectors, and cross-connectors made from medical-grade titanium alloy and cobalt chromium. The current submission is a product line extension adding cannulated and fenestrated screws, percutaneous rods, and associated instruments.
• Technological Characteristics: The added components share the same indications for use, function, material composition, design, range of sizes, and mechanical performance as predicate devices.
• Non-clinical Performance Testing: Static compression bending, static torsion, and dynamic compression bending tests were conducted according to ASTM F1717 to demonstrate comparable mechanical properties to predicate devices.

Therefore, the information regarding acceptance criteria, study design, and data specifics that would be relevant for an AI/ML-based device (e.g., sample size, expert consensus, ground truth, effect size) is not applicable to this submission.
