Mastergraft™ Matrix EXT is to be combined with autogenous bone marrow and is indicated for bony voids or gaps not intrinsic to the stability of the bony structure and can be used as a bone graft extender. The device is to be gently packed into bony voids or gaps of the skeletal system (i.e., the posterolateral spine, intervertebral disc space, pelvis, ilium, and/or extremities). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The device resorbs and is replaced with bone during the healing process. When used in intervertebral body fusion procedures, Mastergraft™ Matrix EXT must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.

Additionally, Mastergraft™ Putty can be used with autograft as a bone graft extender.

Mastergraft™ Putty is to be gently packed into bony voids or gaps of the skeletal system (e.g., the posterolateral spine, intervertebral disc space, pelvis, ileum, and/or extremities).

Mastergraft™ Granules is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. Additionally, Mastergraff™ Granules can be used with autograft as a bone graft extender. Mastergraft™ Granules is to be gently packed into bony voids or gaps of the skeletal system (e.g., the posterolateral spine, intervertebral disc space, pelvis, ilium and/or extremities). These defects may be surgically created osseous defects created from traumatic injury to the bone. Mastergraft™ Granules provides a bone void filler that resorbs and is replaced with bone during the healing process. When used in intervertebral body fusion procedures, Mastergraft™ Granules must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.

The Mastergraft™ Family of bone grafts in this submission includes Mastergraff™ Matrix EXT, Mastergraft™ Strip, Mastergraft™ Putty, and Mastergraft™ Granules. The devices all include osteoconductive biphasic calcium phosphate ceramic granules in different biocompatible physical forms supplied sterile for single patient use.

Mastergraft™ Matrix EXT is made from a combination of medical grade purified collagen of bovine origin and biphasic calcium phosphate ceramic. In the devices, the collagen is a highly purified (>95%) Type I bioresorbable lyophilized collagen. The biphasic ceramic portion of the device is provided in a 15 percent hydroxyapatite and 85 percent B-tricalcium phosphate formulation. Mastergraft™ Matrix EXT is supplied sterile in a premixed strip form for single patient use. Mastergrafi™ Matrix EXT is a biocompatible, osteoconductive, porous implant that allows for bony ingrowth across the graft site while resorbing at a rate consistent with bone healing. The device readily absorbs bone marrow aspirate. Mastergraft™ Matrix EXT is identical to the device cleared in K141824.

Mastergraff™ Strip is made from a combination of medical grade purified collagen of bovine origin and biphasic calcium phosphate ceramic. In the Mastergraft™ Strip device, the collagen is a highly purified (>95%) Type I bioresorbable Iyophilized collagen. The biphasic ceramic portion of the device is provided in a 15 percent hydroxyapatite and 85 percent ß-tricalcium phosphate formulation. Mastergraft™ Strip is supplied sterile in a premixed strip form for single patient use. Mastergrafi™ Strip is a biocompatible, osteoconductive, porous implant that allows for bony ingrowth across the graft site while resorbing at a rate consistent with bone healing. The device readily absorbs bone marrow aspirate and has been shown to heal bone defects. Mastergraft™ Strip is identical to the device cleared in K082166.

Mastergraff™ Putty is made from a combination of medical grade purified collagen of bovine origin and biphasic calcium phosphate ceramic. The collagen component in the Mastergraft™ Putty device is Type I bovine collagen. The biphasic ceramic portion of Mastergraft™ Putty is provided in a 15 percent hydroxyapatite and 85 percent ß-tricalcium phosphate formulation. Mastergraft™ Putty is supplied as a sterile, dry, solid, construct hydrated for single patient use and is a moldable form of bone void filler. Mastergraft™ Putty is an osteoconductive, porous implant that allows for bony ingrowth across the graft site while resorbing at a rate consistent with bone healing. Mastergraft™ Putty is biocompatible. Mastergraft™ Putty readily absorbs bone marrow aspirate and was shown to heal bone defects. Mastergraff™ Putty is identical to the device cleared in K071813.

Mastergraft™ Granules is made of medical grade combination of hydroxyapatite and ßtricalcium phosphate. MASTERGRAFT® Granules is provided in a 15 percent hydroxyapatite and 85 percent ß-tricalcium phosphate formulation. The product is supplied sterile for single patient use. MASTERGRAFT® Granules is an osteoconductive porous implant. Mastergraft™ Granules is identical to the device cleared in K082918.

The provided text is a 510(k) Premarket Notification from the FDA, which focuses on demonstrating substantial equivalence of a new medical device to existing predicate devices. It does not contain information about acceptance criteria or a study that proves the device meets specific performance metrics in the context of an AI/ML medical device.

The document discusses bone void filler devices (Mastergraft™ family) and their indications for use, stating that the current submission expands their use to include intervertebral disc space. The core of the notification is to establish that these devices are substantially equivalent to previously cleared devices. This is a regulatory pathway for medical devices that does not typically involve the kind of detailed performance studies with acceptance criteria, test sets, ground truth establishment, or clinical outcome measures that would be expected for a novel AI/ML diagnostic or prognostic tool.

Therefore, I cannot fulfill your request using the provided text because it does not describe:

1. Acceptance criteria for device performance (in the context of an AI/ML device).
2. A study proving the device meets acceptance criteria. The document references prior clearances and robust analysis from previous studies, but it doesn't detail a new study design, methodology, or results related to specific performance metrics for the current submission.
3. Details about sample sizes for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, or training set details. These are all concepts relevant to the validation of AI/ML models, which are not discussed in this medical device submission.

The "Performance" section explicitly states: "The subject devices have been previously cleared under K141824, K082166, K071813, and K082918, which serve as Reference Devices. These submissions are leveraged to support the device's sterility, shelf-life, endotoxin, pyrogenicity, biocompatibility, and characterizations/bench performance as recommended in FDA's Class II Special Controls Guidance Document for Resorbable Calcium Salt Bone Void Filler Devices. The device's performance in intervertebral spine was supported by a robust analysis of bone grafting materials in the prior posterolateral spine fusion studies." This indicates reliance on previous data and general guidelines, not a new, specific performance study with the requested AI/ML validation metrics.
