Intended Use

The SI-Bonc SI Joint Fusion system is intended for fracture fixation of large bones and large bone fragments of the pelvis for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.

Device Story

The SI-Bone SI Joint Fusion System consists of metallic (titanium) rods with porous plasma spray coating. Designed for surgical implantation into the pelvis to provide fixation for sacroiliac joint disruptions and degenerative sacroiliitis. Rods are 7.0 mm in diameter with lengths ranging from 30 mm to 70 mm. Used by surgeons in an operating room setting to stabilize bone fragments. The device functions as a mechanical bone fastener to facilitate fusion. Clinical benefit is derived from the stabilization of the sacroiliac joint, addressing pain and instability associated with the specified conditions.

Clinical Evidence

Bench testing only. Evidence includes Finite Element Analysis (FEA) comparing the subject device to predicates, and bench-top testing evaluating axial pullout resistance and stability in dynamic cantilever bending. No clinical data provided.

Technological Characteristics

Metallic (titanium) rods with porous plasma spray coating. Dimensions: 7.0 mm diameter, 30-70 mm length. Mechanical fixation device. No software or electronic components.

Indications for Use

Indicated for fracture fixation of large bones and large bone fragments of the pelvis in patients with sacroiliac joint disruptions and degenerative sacroiliitis.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

#### Intended Use:

The SI-Bonc SI Joint Fusion system is intended for fracture fixation of large bones and large bone fragments of the pelvis for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.

#### Device Description

The SI Fusion System consists of a series of metallic (titanium), porous plasma spray coated rods, intended for surgical implant within the bone, to create fixation. Their intended use is for fracturc fixation of large bones and large bone fragments of the pelvis for such conditions as sacroiliac joint disruptions and degenerative sacroiliitis. The system includes 7.0 mm fusion rods, which range in length from 30 mm to 70 mm.

# Performance Data

A Finite Element Analysis (FEA) was performed on the SI Fusion System in comparison to its predicate. In addition, the company has conducted bench-top testing of axial pullout resistance and stability in dynamic cantilever bending. The results demonstrate that the SI Fusion Rod is substantially similar to the predicate devices with respect fixation of the SI joint.

Dear Mr. Dunn:

This letter corrects our substantially equivalent letter of November 26, 2008.

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.
