Intended Use

The Medline UNITE® MIS Foot Recon Screw System is indicated for the stabilization and fixation of bone reconstructions, osteotomies, joint fusions (arthrodeses), and fractures of short (tarsals) and long (metatarsals, phalanges, distal tibia and fibula) bones comprising the foot and ankle. Screws are intended for single use only.

Device Story

System consists of titanium alloy bone screws and associated instrumentation (drill bits, countersinks) for orthopedic fixation. Screws feature Torx drive mechanism, self-tapping, and self-drilling design. Used by surgeons in clinical settings for stabilization of foot/ankle bone reconstructions, osteotomies, joint fusions, and fractures. Implants are single-use, provided non-sterile, and require steam sterilization prior to use. Output is mechanical fixation of bone segments; aids in bone healing and structural stability.

Clinical Evidence

No clinical data. Bench testing only. Torsional yield strength and drive torque evaluated per ASTM F543-23. Axial pullout strength evaluated via engineering analysis.

Technological Characteristics

Materials: Titanium Alloy (Ti-6Al-4V ELI) per ASTM F136 or ISO 5832-3. Design: Torx drive, self-tapping, self-drilling. Dimensions: 2.5mm-4.0mm diameter; 14mm-70mm length. Sterilization: Steam (non-sterile provided).

Indications for Use

Indicated for stabilization and fixation of bone reconstructions, osteotomies, joint fusions (arthrodeses), and fractures of short (tarsals) and long (metatarsals, phalanges, distal tibia and fibula) bones of the foot and ankle.

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.

### Summary of Non-Clinical Testing

The subject Medline UNITE® MIS Foot Recon Screw System does not represent a new worst-case when compared to the previously cleared Medline Cannulated Screws.

- Torsional Yield Strength O
- I The worst-case analysis predicted the subject screws, Medline UNITE® MIS Foot Recon Screw System (K241359), did not create a new worst-case compared to the predicate (K130319) with regard to torsional yield strength. However, testing per ASTM F543-23 was conducted to confirm the analysis. This is highlighted in the provided test reports (TR3270-001 Medline ASTM F543 Torsional Properties and Driving Torque Testing for 2.0mm Headed Screws Final Report.pdf, TR3270-002 Medline ASTM F543 Torsional Properties and Driving Torque Testing for 2.5mm PT Screws Final Report.pdf). The worst-case subject screws, Ø2.5mm PT screws (MSCP2526), were evaluated for torsional yield strength in accordance with ASTM F543-23 A1, exhibiting an average torsional vield strength of 0.66 Nm for six samples compared to the predicate screws, Ø2.0mm Headed Screws (MSD02016), which exhibited an average torsional vield strength of 0.50 N-m . The results from the Ø2.5mm PT Screws exceeds the FDA's Bone Screw SPBP Guidance (https://www.fda.gov/regulatory-information/search-fda-guidance-documents/orthopedic-

#### o Drive Torque

- I The subject screws, the driving and removal torque was only 6.36% of the torsional yield strength. which falls within the the FDA's Bone Screw SPBP Guidance (https://www.fda.gov/regulatory-information/search-fda-guidance-documents/orthopedicnon-spinal-metallic-bone-screws-and-washers-performance-criteria-safety-and-performance ) acceptance criteria of driving or removal torque being less than 50% of the torsional vield.
- 트 The worst-case subject screws were evaluated for drive torque (insertion, removal) in accordance with ASTM F543-23 Annex A2 and met the FDA'S Bone Screw Guidance acceptance criteria for driving torque being less than 50% of the torsional yield strength of the subject screw.
- 0 Axial Pullout Strength
- 트 An engineering analysis was performed to evaluate the axial pullout strength of the worstcase subject screws. The results demonstrated substantially equivalent performance compared to the predicate, Medline Cannulated Screws (K130319) and met the FDA'S Bone Screw Guidance acceptance criteria for predicted shear failure force.

#### Performance Testing (Animal)

This section does not apply. No animal testing was performed.

# Performance Testing (Clinical)

### Summary of Clinical Testing

Not applicable.

### Conclusion

In accordance with 21 CFR Part 807, and based on the information provided in this premarket notification, Medline Industries, LP concludes that the Medline UNITE® MIS Foot Recon Screw System is as safe and as effective for their intended use as the predicate device, Medline Cannulated Screws (K130319).
