EQUIVALENCE TO MARKETED DEVICE
The subject device is substantially equivalent in indications and design principles to the primary predicate device and the additional predicate devices listed above. Provided at the end of this summary is a table comparing the Indications for Use Statements and the technological characteristics of the subject device, the primary predicate device, and the additional predicate devices.
The subject device and the primary predicate device, and additional predicate devices have the same intended use for internal fixation of various bones including those of the lower extremity. The Indications for Use Statement (IFUS) for the subject device is similar to that of the primary predicate device K091479.
The differences among the Indications for Use Statements for the subject device and the additional predicate devices (K061808, K052614, and K000684) include language regarding use in fixation of bones locations other than the lower extremity, use in pediatric patients (K061808), or osteopenic bone (K000684). These differences do not impact substantial equivalence because all IFUS express equivalent intended use for internal fixation of various bones including those of the lower extremity.
The plates from the subject device, the primary predicate device K091479, and the additional predicate devices K061808, K052614, and K000684 have the same technological characteristics, have similar design characteristics, screw holes to accommodate locking and non-locking screws, and use the same operating principles for bone fixation. The plates from the subject device, the primary predicate device, and the additional predicate devices encompass a similar range of physical features and dimensions (number of screw holes, overall length, and thickness) but differ slightly.
The additional predicate devices K061808 and K052614 are for support of substantial equivalence of the subject device plate and screw designs, and for comparison in mechanical testing. In comparative testing of plate and screw constructs, the subject device Calcaneus Step Plates, Calcaneus Opening Wedge Plates (with subject device Wedges), Medial Column Plates, and Talonavicular Plates were shown to be substantially equivalent to plates from the additional predicate device K061808. The subject device Cuneiform plates were shown to be substantially equivalent to plates from the additional predicate device K052614. In comparative testing of screws, the subject device 3.5 TriLock Screws and 3.5 Cortical Screws were shown to be substantially equivalent to screws from the additional predicate device K000684, and the subject device 4.0 Cancellous Screws were shown to be substantially equivalent to screws from the additional predicate device K052614.
Differences among the subject device, the primary predicate K051567, and the additional predicate devices (K061808, K052614, and K000684) include the specific plate designs, the specific lengths of screws, and the materials used for manufacturing (K00684 includes screws manufactured from stainless steel). These differences do not impact substantial equivalence in terms of the intended use for internal fixation of the lower extremity.
The plates, wedges, and screws from the subject device are manufactured from unalloyed titanium conforming to ASTM F67 or from titanium alloy material conforming to ASTM F136 identical to these materials used to manufacture the primary predicate device K091479. All of the subject device final, finished components are manufactured in the same facilities using identical materials and identical manufacturing processes as used for the primary predicate device K091479.
6
The device-specific instruments are made of stainless steel that is identical to the material used for similar Medartis instruments previously cleared in various submissions including K192297 and K181428. The device-specific accessories have similar designs and are made of the identical materials as the Medartis AG accessory trays included in K192297 and K181425.
Mechanical performance evaluation of the subject device included comparative dynamic testing of worstcase simulated fracture or osteotomy constructs. Mechanical testing of subject device screws was performed according to ASTM F543 Standard Specification and Test Methods for Metallic Medical Bone Screws. Based on the results of the testing, the performance of the subject device was judged to be substantially equivalent to the additional predicate devices K061808, K052614, and K000684.
CONCLUSION
The subject device, the primary predicate device, and the additional predicate devices have the same intended use, have similar technological characteristics, and encompass a similar range of physical dimensions appropriate to the anatomy. The subject device and the primary predicate device are made of the identical material. The data included in this submission demonstrate substantial equivalence to the primary predicate device K091479 and the additional predicate devices K061808, 052614, and K000684.
