Indications for Use
TITAN Nail: APTUS Cannulated Compression Screws and headed Cannulated Compression Screws, including TITAN Nails, are indicated for the treatment of fractures, osteotomies and arthrodesis of bones with the appropriate screw size. APTUS K-Wire System: APTUS K-Wire System is intended for use in fixation of bone fractures, for bone reconstruction, and as guide pins for insertion of other implants.
Device Story
TITAN Nail and APTUS K-Wire System are metallic bone fixation implants. TITAN Nails are cannulated, headless, fully threaded titanium alloy screws (ASTM F136) used for fracture treatment, osteotomies, and arthrodesis. APTUS K-Wires are double-ended trocar stainless steel wires (ASTM F138) used for fracture fixation, bone reconstruction, and as guide pins. Both devices are provided sterile via X-ray beam sterilization. Used by surgeons in clinical settings for orthopedic procedures. Output is physical stabilization of bone segments; clinical decision-making relies on surgeon assessment of fracture type and appropriate implant sizing.
Clinical Evidence
No clinical data provided. Substantial equivalence supported by design-control impact assessment and existing non-clinical verification and validation data from predicate devices.
Technological Characteristics
TITAN Nail: Titanium alloy (ASTM F136), cannulated, headless, fully threaded, 12-80mm length, 2.2-4.0mm diameter. APTUS K-Wire: Stainless steel (ASTM F138), 100mm length, 0.8-1.1mm diameter, double-ended trocar. Both: X-ray beam sterilization, mechanical fixation, no software/electronics.
Indications for Use
Indicated for adults requiring treatment of bone fractures, osteotomies, and arthrodesis (TITAN Nail) or bone fixation, reconstruction, and guide pin placement (APTUS K-Wire System).
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.

**Non-Clinical and/or Clinical Tests Summary & Conclusions** 21 CFR 807.92(b)
An analysis of the risk documentation was performed. This determined that the original testing of the predicate devices K232251 and K202589 is not adversely affected by the modification described in this Special 510(k). Such modification does not introduce changes that affect the device's performance, safety, or effectiveness. A comprehensive design review determined that the modification is adequately evaluated by existing verification and validation (V&V) data. Because the modification does not impact the technological characteristics, performance specifications, or materials that form the basis for substantial equivalence to the predicate device, the existing non-clinical performance data remain applicable. Therefore, no additional non-clinical testing was required.
All design verification and validation activities were performed and confirm that the modified device continues to meet its design inputs and performance specifications.
The devices remain in conformity with all previously declared consensus standards within K232251 and K202589, as the modification does not impact performance attributes covered by these standards.
Clinical data is not provided in this submission.
**Conclusion:**
Based on the design-control impact assessment, existing verification and validation data, and unchanged compliance with applicable standards, no new non-clinical testing was required to support this Special 510(k) submission. The existing data continue to demonstrate that the modified device is substantially equivalent to the predicate device.
