Intended Use
DBX® Inject is intended for use as a Demineralized Bone Matrix for voids or gaps that are not intrinsic to the stability of the bony structure. It can be used as follows: | Indications for Use | Putty | Paste | |----------------------|-------|-------| | Extremities | √ | √ | | Posterolateral spine | √ | | | Pelvis | √ | √ | DBX® Inject is indicated for treatment of surgically created osseous defects or osseous defects created from traumatic injury. DBX® Inject Putty can be used as an extender in the spine with autograft. DBX® Inject can be used with bone marrow. DBX® Inject is for single patient use only.
Device Description
DBX® Inject is completely resorbable and is composed of donated cortical and cancellous bone. The bone granules are mixed with sodium hyaluronate (Hy). DBX® Inject consists of DBX Putty or Paste with a separate, sterile plastic syringe for delivery directly into the operative site.
More Information

No
The device description and performance studies focus on the biological properties and processing of demineralized bone matrix, with no mention of AI or ML.

Yes
The device, DBX® Inject, is intended for the treatment of surgically created osseous defects or defects from traumatic injury, which clearly defines a therapeutic purpose.

No
The device, DBX Inject, is a demineralized bone matrix intended for filling osseous defects. It is a therapeutic device used in surgical procedures and does not perform any diagnostic functions.

No

The device description clearly states it is composed of donated bone and sodium hyaluronate, delivered via a plastic syringe, indicating it is a physical medical device, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use of DBX® Inject is for filling bone voids or gaps in the body during surgery. This is a therapeutic use, not a diagnostic one.
  • Device Description: The device is a bone graft material (Demineralized Bone Matrix) delivered via a syringe. This is a surgical implant/material, not a diagnostic test.
  • Lack of Diagnostic Elements: There is no mention of analyzing samples from the body (like blood, urine, tissue) to diagnose a condition or provide information about a patient's health status.
  • Performance Studies: The performance studies focus on the osteoinductive potential of the bone matrix and viral inactivation, which are relevant to the safety and efficacy of a bone graft material, not a diagnostic test.

IVD devices are used in vitro (outside the body) to examine specimens from the human body to provide information for diagnostic, monitoring, or compatibility purposes. DBX® Inject is used in vivo (inside the body) for a therapeutic purpose.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Osteoinductive Potential:
DBX® Inject is osteoconductive, and has been shown to have osteoinductive potential in an athymic mouse model. Every lot of final DBX® Inject Paste will be assayed in vivo for osteoinductive potential. Every lot of final DBX® Inject Putty product will be tested in an athymic mouse model or in an alkaline phosphatase assay, which has been shown to have a positive correlation with the athymic mouse model, to ensure the osteoinductive potential of the final product. Standard testing performed in an athymic mouse or alkaline phosphatase assay must prove positive for lot release. It is unknown how the osteoinductive potential, measured in the athymic mouse model or the alkaline phosphatase assay, will correlate with clinical performance in human subjects.

Viral Clearance and Inactivation:
The method for processing the demineralized bone matrix contained in DBX® Inject was evaluated for its viral inactivation potential. A panel of model potential human viruses representing various virus types, sizes, shapes and genomes were evaluated. The DBM processing methods were determined to provide significant viral inactivation potential for a wide range of potential viruses.

DBX® Inject is osteoconductive, and has been shown to have osteoinductive potential in an athymic mouse model. Every lot of final DBX® Inject Paste will be assayed in vivo for osteoinductive potential. Every lot of final DBX® Inject Putty product will be tested in an athymic mouse model or in an alkaline phosphatase assay, which has been shown to have a positive correlation with the athymic mouse model, to ensure the osteoinductive potential of the final product. Standard testing performed in an athymic mouse or alkaline phosphatase assay must prove positive for lot release. It is unknown how the osteoinductive potential, measured in the athymic mouse model or the alkaline phosphatase assay, will correlate with clinical performance in human subjects.

Viral Clearance and Inactivation:

The method for processing the demineralized bone matrix contained in DBX® Inject was evaluated for its viral inactivation potential. A panel of model potential human viruses representing various virus types, sizes, shapes and genomes were evaluated. The DBM processing methods were determined to provide significant viral inactivation potential for a wide range of potential viruses.

Safety and Effectiveness Information

DBX® Inject is single-donor processed. The donor suitability criteria used to screen this donor are in compliance with the FDA regulations published in 21 CFR Part 1270 and Part 1271 Human Tissue Intended for Transplantation.

Conclusion

Musculoskeletal Transplant Foundation believes that the information provided in this 510(k) submission establishes that similar legally marketed devices have been used for the same clinical applications as the DBX® Inject. The materials from which DBX® Inject is fabricated have an established history of use, and the device has been tested in accordance with applicable FDA guidelines.
