Grafton™ DBM and Grafton Plus ™ DBM Paste are intended for use as a bone graft extender, bone graft substitute, and bone void filler in bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space (excluding Flex or Crunch), pelvis and extremities) not intrinsic to the stability of the bony structure. The voids or gaps may be surgically created defects or defects created by traumatic injury to the bone. When used in intervertebral body fusion procedures, Graft™ DBM (excluding Flex or Crunch) and Grafton Plus ™ DBM Paste must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
Grafton™ DBM and Grafton Plus™ DBM Paste are absorbed/remodeled and replaced by host bone during the healing process.
Magnifuse™ Bone Graft is intended for use as a bone graft substitute in bony voids or gaps of the skeletal system (i.e., posterolateral spine, intervertebral disc space, pelvis and extremities) not intrinsic to the stability of the bony structure. Voids or gaps may be surgically created defects or defects created by traumatic injury to the bone.
Magnifuse™ Bone Graft may be used in a manner comparable to autogenous bone or allograft bone. Magnifuse™ Bone Graft may be mixed with fluid such as bone marrow aspirate, blood, sterile water, or sterile water in order to adjust consistency and handling of bone graft material.
When used in intervertebral body fusion procedures, Magnifuse™ Bone Graft must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
Magnifuse™ Bone Graft is resorbed/remodeled and is replaced by host bone during the healing process.
The Grafton™ DBM, Grafton Plus™ DBM Paste, and Magnifuse™ Bone Graft devices in this submission are human bone products containing human demineralized bone matrix (DBM).
Grafton™ DBM is a human bone product that contains human DBM with an inert additive. Grafton™ DBM is produced in particular physical forms (Grafton™ DBM Gel, Grafton™ DBM Putty, Grafton™ DBM Matrix, Grafton™ DBM Orthoblend) and/or handling property. Grafton™ DBM is provided in ready-to-use form and is intended in single patient, single use containers. Grafton™ DBM is identical to the device cleared in K051195.
Grafton Plus™ DBM Paste is human demineralized bone matrix combined with an inert additive to yield a product having a particular physical form and/or handling property. Grafton Plus™ DBM Paste is identical to the device cleared in K043048.
Magnifuse™ Bone Graft is a human bone allograft product containing human DBM and surface demineralized cortical bone chips sealed in an absorbable mesh pouch for intraoperative handling. It is intended for use in filling bony voids or gaps or the skeletal system not intrinsic to the stability of the bony structure. Magnifuse™ Bone Graft is provided ready-to-use in various package sizes by volume or dimension and is intended for single patient use. Magnifuse™ Bone Graft is identical to the device cleared in K082615.
This FDA 510(k) clearance letter (K251193) is for bone graft materials (Grafton™ DBM, Grafton Plus™ DBM Paste, Magnifuse™ Bone Graft) and does not describe an AI/software device or a study with "acceptance criteria" based on AI performance metrics like sensitivity, specificity, or reader studies.
The document details the substantial equivalence of new product formulations/expanded indications for use to previously cleared predicate and reference devices. The "performance" section refers to pre-clinical testing and leveraging prior clearances for bone graft characteristics (e.g., DBM properties, viral inactivation, shelf-life, biocompatibility in animal models, etc.), not a clinical study involving human readers or AI algorithm performance.
Therefore, I cannot provide the information requested in your prompt as it pertains to AI device acceptance criteria and performance studies. The document does not contain:
- A table of acceptance criteria and reported device performance for an AI system.
- Sample sizes for a test set, data provenance, or expert ground truth establishment for an AI study.
- Details on MRMC studies or human reader improvement with AI assistance.
- Standalone algorithm performance.
- Description of ground truth type for an AI system.
- Training set sample size or how ground truth for training was established for an AI system.
The "Performance" section explicitly states: "The devices' performance in the intervertebral body space was supported by a robust analysis of bone grafting materials in the prior posterolateral spine fusion studies." This refers to biological and mechanical performance of the bone graft materials themselves, not an AI software.
§ 888.3045 Resorbable calcium salt bone void filler device.
(a)
Identification. A resorbable calcium salt bone void filler device is a resorbable implant intended to fill bony voids or gaps of the extremities, spine, and pelvis that are caused by trauma or surgery and are not intrinsic to the stability of the bony structure.(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Resorbable Calcium Salt Bone Void Filler Device; Guidance for Industry and FDA.” See § 888.1(e) of this chapter for the availability of this guidance.
