DYNANAIL MINI® ACTIVE, ADAPTIVE HEALING FOR MIDFOOT & HINDFOOT FUSION

1. FEATURES BROCHURE FB DYNANAIL MINI® ACTIVE, ADAPTIVE HEALING FOR MIDFOOT & HINDFOOT FUSION NAIL SYSTEM

2. SAME MAINTAINED COMPRESSION, SMALLER FORM DYNANAIL MINI® The DynaNail Mini® Fusion System offers the same dynamic compression benefits as its larger predecessor, the DynaNail®, just in smaller form for medial column fusion and subtalar fusion. • Offers between 2 - 5.5 mm of post-operative compression PLUS intra- operative manual compression1 Transverse Screw • Provides strong joint stability due to maintained compression • Dual transverse screw fixation prevents device migration AMOUNT OF POST-OPERATIVE COMPRESSION BY IMPLANT LENGTH Titanium Outer Nail Body Internal NiTiNOL Compressive Element NAIL LENGTH COMPRESSION 60 MM 1.8 MM 70 MM 2.2 MM Slotted Calcaneal Screw Hole 80 MM 2.8 MM 90 MM 3.4 MM 100 MM 4.0 MM 4.0MM 110 MM 120 MM 4.5 MM Transverse Screw 130 MM 5.1 MM Sliding Element 140 MM 5.6 MM DynaNail Mini® for Subtalar Fusion DynaNail Mini® for Medial Column Fusion

3. DYNANAIL HYBRID™ The DynaNail Hybrid™ offers surgeons another robust option for subtalar fusion procedures. The implant’s “hybrid” design combines the dynamic compressive power and stability of a nail with the easy insertion and anatomical friendliness of a screw. The internal NiTiNOL Element maintains active compression up to 5 mm of bone settling and resorption depending on implant length for extra compressive power.2 16 mm proximal talar threads allow for easy insertion. AMOUNT OF POST-OPERATIVE COMPRESSION BY IMPLANT LENGTH NAIL LENGTH COMPRESSION 60 MM 2.2 MM Internal NiTiNOL Element provides up to 5 mm of post-operative compression. 70 MM 3.0 MM Distal Transverse Screw provides stability and prevents device migration. 80 MM 3.8 MM 90 MM 4.5 MM 100 MM 5.3 MM

4. IT’S SUPERELASTIC THE “RUBBER-BAND” EFFECT The DynaNail Mini® features DJO’s patented and proven superelastic NiTiNOL technology.3,4 The internal NiTiNOL Compressive Element is pre-stretched (1 in graph to right) and fixed with screws (2). Post- surgery, the NiTiNOL Element will automatically recover its stretched length due to unloading in response to bone resorption or settling (3), analogous to a very strong rubber band. 2 UNLOAD 1 STRETCH 3 STRESS PSEUDOELASTIC RECOVERY STRAIN (%)

5. SEE THE COMPRESSIVE ELEMENT IN ACTION The distance the NiTiNOL Element recovers can be measured and tracked on x-ray post-surgery. In this case, with a 70 mm DynaNail Mini®, the Calcaneal Screw is located 0.8 mm from proximal end of Nail Outer Body slot, indicating the NiTiNOL Element has recovered 1.4 mm of its stretched length with 0.8 mm of compression remaining. 0.8 MM COMPRESSION REMAINING 0.8 MM COMPRESSION REMAINING 1.4 MM POST- OPERATIVE COMPRESSION RECOVERED 7-weeks post-operative x-ray of a 70 mm DynaNail implanted in an 83-year-old female Images courtesy of Kent Ellington, MD (OrthoCarolina Foot & Ankle Institute, Charlotte, NC)

6. DYNANAIL MINI® COMPRESSION PERFORMANCE SUMMARY THE PROOF IS IN THE SCIENCE MAINTAINED ACTIVE COMPRESSION 400 COMPRESSIVE FORCE (N) 300 DYNANAIL MINI® Unlike traditional screws that lose compression post-operatively, the DynaNail Mini® Family is the only solution for midfoot and hindfoot fusion that maintains active compression throughout healing. Both the DynaNail Mini and the DynaNail Hybrid™ provide up to ~5 mm of maintained active compression in response to bone settling or resorption, depending on implant length.1,2 200 100/110 MM 140 MM WRIGHT SALVATION BEAM™ 120 MM 80 MM 90 MM 100 140 MM 130 MM 70 MM 95 MM 0 0 1 2 3 4 5 RESORPTION (MM) DYNANAIL HYBRID™ COMPRESSION PERFORMANCE SUMMARY 400 COMPRESSIVE FORCE (N) 300 DYNANAIL HYBRID™ 200 100 MM PARAGON 28 MONSTER® 7 x 80 MM 80 MM 90 MM 100 ACUMED ACUTRAK 2® 7.5 x 80 MM 70 MM 0 0 1 2 3 4 5 RESORPTION (MM)

7. PRE-LOADED ASSEMBLY ENHANCED INTRAOPERATIVE EFFICIENCY The DynaNail Mini® and DynaNail Hybrid™ come pre-stretched and pre-loaded on a disposable Nail Guide. Just connect the Nail Guide to the Targeting Frame and implant.

8. UNIVERSAL INSTRUMENTATION DynaNail Mini® and DynaNail Hybrid™ share universal instrumentation for added intraoperative flexibility and efficiency.

10. WHAT OUR SURGEONS SAY... “I was initially attracted to the DynaNail Mini® due to its excellent post-operative compression, particularly in patients with poor bone quality. From my experience so far, I have found the nail to be easy to use and the results reproducible across my patient population.” TERRENCE PHILBIN, DO Columbus, OH “As a big believer in the dynamic compression capabilities of NiTiNOL in promoting fusion, I am pleased to add the DynaNail Mini to my arsenal of surgical tools. The DynaNail Mini offers the same benefits of sustained post-operative compression as its predecessor, the DynaNail, but now in a smaller size expanding the use of NiTiNOL to other indications.” KENT ELLINGTON, MD Charlotte, NC
