Intended Use

The SAMBA™ Screw System is intended for fixation of sacroiliac joint disruptions. This fixation device is to only be used in skeletally mature patients.

Device Story

SAMBA Screw System is a cannulated metallic bone screw for stabilization of sacroiliac (SI) joint disruptions. Device is implanted by a surgeon in a clinical setting. Screw features 9 mm diameter, 25-50 mm lengths, and multiple longitudinal slots on the shaft to facilitate fixation. Provided sterile for single use; not intended for resterilization.

Clinical Evidence

Bench testing only. Mechanical performance verified via static axial pull-out strength, static torsion, static cantilever bending, and dynamic cantilever bending tests in accordance with ASTM F2193-02 (2007) and ASTM F543-07.

Technological Characteristics

Material: Implant-grade Titanium (Ti-6Al-4V ELI) per ASTM F136. Design: Cannulated bone screw, 9 mm diameter, 25-50 mm length, longitudinal shaft slots. Sterilization: Provided sterile. Standards: ASTM F2193-02, ASTM F543-07.

Indications for Use

Indicated for fixation of sacroiliac joint disruptions in skeletally mature patients.

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.

Predicate Devices

• Synthes 6.5mm Cannulated Screw (K021932)
• SI-LOK Sacroiliac Joint Fixation System (K112028)

| Trade Name: | SAMBA™ Screw System |
| Classification: | Class II, Smooth or threaded metallic bone fixation fastener (21<br>CFR 888.3040) |
| Product Code: | HWC, OUR |
| Predicate Device(s): | The subject device is equivalent to the following devices:<br>• Synthes 6.5mm Cannulated Screw (K021932)<br>• SI-LOK Sacroiliac Joint Fixation System (K112028) |
| Device Description: | The SAMBA screw is a cannulated metallic bone screw<br>designed to stabilize the sacroiliac (SI) joint. The SAMBA<br>screw is composed of implant-grade Titanium, Ti-6Al-4V ELI,<br>conforming to ASTM F-136. The SAMBA screw is 9 mm in<br>diameter and offered in 25-50 mm lengths with multiple<br>longitudinal slots on its shaft. Each slot set consists of four (4)<br>holes oriented 90 degrees apart around the circumference of the<br>screw at specified axial location. It will be provided as sterile,<br>single units packaged in a sealed tray and pouch. The screw is a<br>single use device and is not intended to be resterilized. |
| Intended Use: | The SAMBA™ Screw System is intended for fixation of<br>sacroiliac joint disruptions. This fixation device is to only be<br>used in skeletally mature patients. |
| Functional and<br>Safety Testing: | To verify that device design met it's functional and performance<br>requirements, representative samples of the device underwent<br>mechanical testing for static axial pull out strength, static<br>torsion, static cantilever bending, and dynamic cantilever<br>bending in accordance with the following standards:<br>• ASTM F2193-02 (2007) Standard Specifications and<br>Test Methods for Components Used in the Surgical<br>Fixation of the Spinal Skeletal System<br>• ASTM F543-07 Standard Specification and Test<br>Methods for Metallic Medical Bone Screw |
| Conclusion: | Medical Designs considers the SAMBA Screw System to be<br>equivalent to the predicate device listed above. This conclusion<br>is based upon the devices' similarities in principles of operation,<br>technology, materials and indications for use. |

Dear Ms. Kristi Vondra:

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.
