MagnetOs Granules is an implant intended to fill bony voids or gaps of the skeletal system, i.e., the extremities, pelvis, intervertebral disc space, and posterolateral spine. These osseous defects may be surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure.

When used in posterolateral spine, extremities and pelvis, MagnetOs Granules may be used standalone or mixed with autograft, blood, and/or bone marrow. When used in intervertebral body fusion procedures, MagnetOs Granules must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler and hydrated with blood. MagnetOs Granules may also be mixed with autograft.

MagnetOs Granules resorbs and is replaced with bone during the healing process.

MagnetOs Granules is a synthetic, resorbable, osteoconductive bone void filler for the repair of bony defects. MagnetOs Granules consists of 65-75% tri-calcium phosphate (TCP - Ca3(PO4)2) and 25-35% hydroxyapatite (HA - Ca10(PO4)6(OH)2) granules with a porous trabecular structure that resembles the interconnected porosity of human cancellous bone. MagnetOs Granules guide the three-dimensional regeneration of bone in the defect site into which it is implanted. New bone will be deposited on the surface of the graft when placed next to viable host bone. The graft resorbs and is replaced by bone during the natural process of bone remodeling. MagnetOs Granules is a ready-to-use product. MagnetOs Granules is provided in vials in a range of product volumes. MagnetOs Granules is gamma-sterilized and sterile packaged for single use only.

The total interconnecting porosity of MagnetOs Granules is 70 ± 15%. Pore diameters in the scaffold range from 0 to 1000 µm (1mm).

The provided document is a 510(k) summary for a medical device called MagnetOs Granules. It does not describe acceptance criteria for a diagnostic AI/ML device, nor does it contain a study that proves a device meets such criteria. Instead, it details the substantial equivalence of MagnetOs Granules to predicate devices for its intended use as a bone void filler.

Therefore, I cannot extract the information required to answer your query. The document mentions "non-clinical testing data," "animal testing," and a "clinical study" for MagnetOs Granules itself, but these are for demonstrating the safety and effectiveness of a bone void filler for orthopedic application, not for evaluating the performance of an AI/ML diagnostic tool against specific acceptance criteria like sensitivity, specificity, or AUC.

The information you've requested (acceptance criteria table, sample size for test set, expert qualifications, adjudication method, MRMC study, standalone performance, ground truth type, training set size, and training set ground truth establishment) are typical for the evaluation of a diagnostic AI/ML algorithm. This document is related to a different type of medical device (a resorbable calcium salt bone void filler) and does not provide these details.
