Intended Use

DBX® Strip is indicated as a bone void filler for treatment of surgically created osseous voids or gaps that are not intrinsic to the stability of the bony structure. It can be used in the pelvis, extremities, and the posterolateral spine for posterolateral fusion. DBX® Strip, when used for posterolateral spine fusion, may be used with autograft. DBX® Strip is for single patient use only.

Device Story

DBX® Strip is a malleable bone void filler composed of human demineralized bone matrix (DBM), sodium hyaluronate, sodium phosphate dibasic buffer, and porcine gelatin. Used by surgeons to fill osseous voids or gaps in the pelvis, extremities, and posterolateral spine. Provides an osteoconductive scaffold and possesses osteoinductive potential. Supplied in five sizes for single-patient use. Clinical benefit derived from supporting bone healing in non-load-bearing defects.

Clinical Evidence

No clinical data provided. Biocompatibility established via ISO 10993 testing. Osteoinductivity potential verified in athymic mouse model. Viral inactivation validated via testing against a panel of model human viruses. Sterility tested per USP <71>.

Technological Characteristics

Materials: Human demineralized bone matrix (DBM), sodium hyaluronate, sodium phosphate dibasic buffer, porcine gelatin. Form factor: Flat, malleable strip in five sizes. Biocompatibility: ISO 10993. Sterilization: Aseptic processing, USP <71> sterility testing. Osteoconductive and osteoinductive.

Indications for Use

Indicated for treatment of surgically created osseous voids or gaps not intrinsic to bony stability in the pelvis, extremities, and posterolateral spine (for fusion). May be used with autograft in spine fusion. Single patient use.

Regulatory Classification

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.

Special Controls

#### INDICATIONS FOR USE:

DBX® Strip is indicated as a bone void filler for treatment of surgically created osseous voids or gaps that are not intrinsic to the stability of the bony structure. It can be used in the pelvis, extremities, and the posterolateral spine for posterolateral fusion. DBX® Strip, when used for posterolateral spine fusion, may be used with autograft.

DBX® Strip is for single patient use only.

### DEVICE DESCRIPTION:

DBX® Strip is a flat, malleable device composed of human demineralized bone matrix (DBM), sodium hyaluronate (NaHy), sodium phosphate dibasic buffer and gelatin (procine origin). DBX® Strip is for single patient use only and is available in five sizes.

#### SUBSTANTIAL EQUIVALENCE INFORMATION:

DBX® Strip was cleared by FDA (K042829) as a bone void filler for use in the posterolateral spine. The new DBX® Strip is substantially equivalent to DBX® Strip, FDA cleared K042829. The only modification is the expansion of the indications to include use of DBX® Strip in the pelvis and extremities.

### SAFETY AND EFFECTIVENESS INFORMATION:

Biocompatibility of DBX® Strip materials has been established through their long history of safe and effective clinical use, further supported by laboratory testing conducted per ISO 10993. DBX® Strip is single-donor processed using aseptic techniques and is tested for sterility per current USP <71>.

### OSTEOINDUCTIVITY POTENTIAL:

DBX® Strip is osteoconductive, and has been shown to have osteoinductivity potential in an athymic mouse. Every lot of final product will be tested to ensure the osteoinductive potential of the final product. Osteoinduction assay results in the athymic mouse model should not be interpreted to predict clinical performance in human subjects.

### VIRAL CLEARANCE AND INACTIVATION:

A panel of model potential human viruses representing various virus types, sizes, shapes and genomes were evaluated. The viral inactivation testing demonstrated suitable viral inactivation potential of the processing method for a wide spectrum of potential human viruses. The DBX® Strip process further reduces the risk of viral contamination beyond donor testing and screening procedures.

Dear Ms. Bennewitz:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
