Device Story
Intraosseous Fusion Device (IFD) is a threaded, hollow, fenestrated titanium implant designed for bone stabilization and arthrodesis. Input: bone graft material (packed into hollow center). Operation: implant provides mechanical fixation via interrupted external threads; fenestrations allow bone ingrowth. Output: stabilized bone segments. Used in clinical settings by orthopedic surgeons for foot/ankle/small joint reconstruction. Healthcare providers use the device to facilitate fusion and fracture healing; benefits include minimally invasive reconstruction and enhanced bone integration. System includes implants (6, 9, 12mm diameters; 10, 15, 20mm lengths), surgical instruments, and storage/sterilization trays.
Clinical Evidence
Bench testing only. Mechanical testing included torsional strength, driving torque, and axial pullout (ASTM F543), and static/cyclic radial compression (ASTM F2077). Biocompatibility (cytotoxicity), steam sterilization validation (ISO 17665-1, ISO 14937), manual cleaning validation (AAMI TIR12, AAMI TIR30), and shipping simulation (ISTA 3A) were performed.
Technological Characteristics
Material: Ti-6Al-4V alloy (ASTM F136, F3001). Design: Threaded, cannulated, headless, fenestrated, interrupted thread. Dimensions: 6-12mm diameter, 10-20mm length. Energy: Mechanical fixation. Sterilization: Steam sterilization (non-sterile delivery). Connectivity: None.
Indications for Use
Indicated for skeletally mature individuals requiring fracture repair, arthrodesis, osteotomy, joint fusion, or fragment fixation in the foot, ankle, and small joints. Not for spinal use.
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.

# DEVICE DESCRIPTION
The Intraosseous Fusion Device (IFD) is a threaded titanium implant that is designed to provide stabilization of bones, bone segments or bone fragments to facilitate arthrodesis. The implant has an interrupted external thread to facilitate placement and fixation. The implant is hollow, which allows packing of bone graft material, and fenestrated, which allows bone growth and formation throughout the implant. The implants come in a variety of diameters (6, 9, 12mm) and lengths (10, 15 & 20mm) to address different anatomy locations. The implants are made from Ti6-6Al-4V alloy. The Intraosseous Fusion Device System includes implants, the instruments necessary to implant them, and the tray system for transport, storage and sterilization. The system is provided non-sterile and
{4}------------------------------------------------
requires steam sterilization at point of use. Single-use metallic implants are time stable. Reusable instruments are inspected in reprocessing for conditions compromising function. All instruments (except for k-wires) are reusable and can be reprocessed.
Image /page/4/Figure/2 description: The image shows a cylindrical object with a complex, repeating pattern on its outer surface. The object appears to be hollow, with a smooth inner surface and several circular holes distributed along its length. The outer surface is covered in a grid-like arrangement of raised, rectangular blocks, creating a textured and segmented appearance. The object is rendered in a neutral gray color, giving it a metallic or industrial look.

# CONCLUSION
The subject Intraosseous Fusion Device System has same intended use and similar indications for use, the similar technology, comparable principles of operation, and similar materials as the identified predicate systems: Subchondral Solutions- S4 Screw (K191995) and OrthoSolutions-System26 Bone Screws (K163489). The IFD System does not raise any new questions of safety or effectiveness as compared to the predicate systems. Performance testing according to ASTM F543 demonstrates substantially equivalent mechanical performance of the subject device as compared to the System26 Bone screws currently on the market. Therefore, the Intraosseous Fusion Device System is substantially equivalent to the identified predicate systems.
