Synthes Dental Bone Cutting Instruments K150796 is used as a reference device in support of this submission. #### DEVICE DESCRIPTION Taps are used to drill a hole and simultaneously create threads in order to accommodate a Rapid Resorbable Fixation System bone screw. The self-drilling fixed-stop taps are manufactured from Stainless Steel 440A which conforms to ASTM F899 Standard Specification for Stainless Steel for Surgical Instruments and ASTM A276 Specification for Stainless Steel Bars and Shapes. The adjustable-length taps (final assembly) are assembled from three components; the adjustable tap (Stainless Steel 440A), the locking collar (Makrolon Rx2530 W/1118 Tint), and the stop collar (Stainless Steel 316L with an aluminum titanium nitride coating). DePuy Synthes Taps for Resorbable Screws can be used with the following handles: 311.01.98 Handle, with mini quick coupling 311.03 Handle, with mini quick coupling, small 311.005 Screwdriver Handle with hex coupling, small 311.006 Screwdriver Handle with hex coupling, medium 311.007 Screwdriver Handle with hex coupling, large The DePuy Synthes Taps for Resorbable Screws can be used with the DePuy Synthes Rapidsorb® Rapid Resorbable Fixation System (K062789) screws [1.5mm, 2.0mm, 2.5mm (Emergency) diameters] and plates (1.5 mm and 2.0mm). {4}------------------------------------------------ Image /page/4/Picture/0 description: The image shows the logo for Synthes. The logo consists of a circular symbol on the left and the word "SYNTHES" in bold, sans-serif font on the right. The circular symbol appears to be a stylized representation of a medical device or implant. A registered trademark symbol is located to the right of the word "SYNTHES". ## INDICATIONS FOR USE #### Taps for Resorbable Screws Taps are nonpowered hand-held devices intended for bone cutting and drilling on a patient's skull during fracture repair and reconstructive procedures of the cranium. The taps may be used to prepare cranial bone to insert bone fixation screws. #### Medtronic Sofamor Danak POWEREASE System (Primary Predicate) IPC® System is indicated for the incision/cutting, removal, drilling and sawing of soft and hard tissue and bone, and biomaterials in Neurosurgical (Craniofacial), Orthopedic, Arthroscopic, Spinal, Sternotomy, and General surgical procedures. The IPC® POWEREASE™ System is indicated for drilling, tapping and driving screws and working end attachments during spinal surgery, including open and minimally invasive procedures. It is also used in placement or cutting of screws, posts and rods. #### Discussion Both the subject taps and the primary predicate Medtronic Sofamor Danek POWEREASE System K123270 are intended for use in neurosurgical procedures to drill or cut into the skull. There is a difference in the assigned FDA product codes: - The subject taps are manual instruments, with a corresponding product code of . HBG (Drills, burrs, trephines, and their accessories - manual). - The primary predicate is a powered instrument with the corresponding product code of HBE (drills, burrs, trephines, and accessories - simple, powered). Additionally, the subject taps defined herein as Class II product code HBG are the same instruments currently marketed by Synthes as Class I product code LXH (Orthopedic manual surgical instruments). Thus, the subject taps include the intended uses of both product codes (i.e. cranial bone-cutting and general orthopedic bone cutting). The reference device Synthes Dental Bone Cutting Instruments K150796 does not have the same intended use as the subject taps since the dental bone cutting instruments are intended for trauma, reconstruction, or orthognathic procedures to drill or cut into the upper or lower jaw. The reference device product code is DZJ (Driver, wire, and Bone Drill Manual). Since taps for general orthopedic bone-cutting would typically be considered Class I Exempt instruments, the identified reference device is included to show that taps have been previously cleared within premarket notification submissions. ## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE #### Primary Predicate DePuy Synthes considers the subject taps equivalent to the Medtronic Sofamor Danek Sofamor Danek POWEREASE™ System K123270, as well as the Synthes Dental Bone Cutting Instruments K150796. {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the word "SYNTHES" in bold, black letters. To the left of the word is a circular logo with a design inside. A small "R" in a circle is located to the right of the word "SYNTHES", indicating that it is a registered trademark. ### Technological Similarities of Taps to the Primary Predicate - Both instruments are used for drilling a hole in preparation for a bone screw ● - . Both are used in the skull - Both can be used manually - The Medtronic POWEREASE™ System consists of a hand piece and ● attachments; the subject taps consist of the instruments and handles based on the coupling ### Technological Differences of Taps to Primary Predicate - The Medtronic POWEREASE™ System is used for drilling, tapping and driving . screws as well as for the placement or cutting of screws, posts and rods; the tap is used to drill a hole and simultaneously create threads in order to receive a bone screw - The Medtronic POWEREASE™ System can be used manually or with power; the ● subject taps are manual instruments only - The Medtronic IPC® and POWEREASE™ Systems (K123270) are used in ● Neurosurgical (Cranial, Craniofacial), Orthopedic, Arthroscopic, Spinal, Sternotomy, and General surgical procedures; the subject taps are intended for neurosurgical procedures only #### Impact on Safety and Effectiveness There is no impact to safety and effectiveness. The subject devices have a limited intended use compared to the predicate device; the POWEREASE System is used for drilling, tapping, and driving screws while the taps are used to cut bone in preparation of receiving a bone screw. The subject devices are basic handheld instruments compared to the predicate; the tap is connected to a handle (dependent on the coupling feature) while the predicate device consists of a handpiece and multiple attachments. The subject devices are used manually while the predicate can be used either manually or with power. #### Reference Device Both the subject taps and the reference Dental Bone Cutting Instruments (K150796) are generally intended to be used during surgery for cutting into bone. The reference device is included to show that taps have been cleared within premarket submissions. #### Technological Similarities of Taps to the Reference Device - Both devices are intended to be used to prepare bone for placement of a screw - Both devices are operated manually ● - Both are manufactured from stainless steel (440A) . #### Technological Differences of Taps to the Reference Device - The subject taps are intended for use in fracture repair and reconstructive procedures of the cranium (covered under a Neurology product code); the Dental Bone Cutting Instruments are intended for use in oral/maxillofacial surgery (covered under a Dental product code). {6}------------------------------------------------ Image /page/6/Picture/0 description: The image shows the Synthes logo. The logo consists of a circular symbol on the left and the word "SYNTHES" in bold, sans-serif font on the right. A registered trademark symbol is located to the upper right of the word "SYNTHES". A horizontal line is located underneath the logo. ### Impact on Safety and Effectiveness There is no impact to safety and effectiveness. The subject taps are intended for use in fracture repair and reconstructive procedures of the cranium (Neurology); the Dental Bone Cutting Instruments are intended for use in oral/maxillofacial surgery (Dental). Regardless of specific intended use, all taps are used to cut bone in preparation of receiving a bone screw. The reference device was included to provide evidence that taps have been cleared within premarket notification submissions. ## PERFORMANCE DATA ### Mechanical Testing The performance data provided in support of substantial equivalence of the proposed devices are as follows: - Simulated Use/Bioskills Lab ● - Sawbones Lab ● - Torsional Testing of RapidSorb Taps - . RapidSorb Self-Drilling Tap Axial Load at Strip Out - Validation of Hex Coupling for RapidSorb Adjustable Taps ● - Biocompatibility Testing - Cytotoxicity | Performance Testing - Bench | | | |--------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Test | Test Method Summary | Results | | Simulated Use/Bioskills Lab - RapidSorb Instruments | A representative range of the subject devices will be selected to represent the entire range of taps. The lab will be conducted to validate various aspects of the device design such as torque resistance, length and screw size diameter. The validation lab will consist of 5 individual participants. There will be 4 cadaveric cephalises. The heads (cephalises) will be selected to represent a range of patients (a young male and female, and elderly male and female). The users are independent from the design of the subject device. | The results indicated full validation of the subject device. All acceptance criteria were met. | | Saw Bones Lab - RapidSorb Instruments | The objective of the lab is to validate that the subject taps are able to self-drill in normal density bone. A representative range of the subject device will be selected to represent the entire range of taps. The range includes all diameters and the longest length of each tap. These represent worst case in regard to torque resistance. | The acceptance criteria was met in that all four users were able to use each of the three subject taps to create three separate tapped holes that will accommodate the corresponding screw (36 total insertions). | {7}------------------------------------------------ Image /page/7/Picture/0 description: The image shows the logo for Synthes.

Two separate tests will be performed, Failure Torque Test and Stripping Torque Test. | The results of this testing indicate that when the failure torque of all three sizes of RapidSorb Self Drilling Taps (1.5, 2.0, and 2.5 mm) are compared to their respective bottoming or stripping torque, the resulting p-values were all 0.000. There is sufficient evidence to reject the null hypothesis in favor of the alternate, that in all cases the RapidSorb failure torque is superior to the Bottoming or Stripping torque (as specified). This satisfies the acceptance criteria. | | | | | | Mechanical Test - RapidSorb Self-Drilling Tap Axial Load at Strip Out | The objective of this test was to demonstrate that the axial force required to cause the adjustable stop on the adjustable length taps (311.100, 311.101, 311.102, 311.110, 311.111, 311.112) to unintentionally move is greater than the axial force that is generated by the strip out torque of each tap. | As can be seen in all comparisons (1.5, 2.0, and 2.5mm) the resulting p-value was 0.000, which is sufficient evidence to reject the null hypothesis in favor of the alternate that the Axial load required to move the adjustable stop was superior to the axial load at strip-out in all cases. This result satisfies the acceptance criteria. | | | | | | Validation of Hex Coupling for RapidSorb Adjustable Taps | The objective of this test was to validate the compatibility of the Hex coupling on the proximal end of the RapidSorb Adjustable length taps. All tested parts will couple with the designated hex handles and, then be fully inserted into 40 lbs/cf polyurethane foam with no slippage or visible damage (no magnification) of taps proximal coupling. | At the conclusion of the testing, all participants were able to drive all 12 taps with a combination of the 3 specified handles. This was done with no visible damage to the proximal coupling end of the tap. | | | | | | Biocompatibility (Cytotoxicity) | An in vitro study was conducted to evaluate for potential cytotoxic effects, following guidelines of the ANSI/AAMI/ISO 10993-5, Biological Evaluation of medical devices – Part 5: Test for in vitro cytotoxicity (2009). | At the conclusion of the testing, the test articles extract showed no reactivity of causing cell lysis or toxicity. All test method acceptance criteria were met. The patient contacting components of taps are manufactured from Stainless Steel 440A which conforms to the FDA recognized consensus standard, ASTM F899 - Standard Specification for Stainless Steel for Surgical Instruments, supporting the biocompatibility of this device. | | | | | {8}------------------------------------------------ Image /page/8/Picture/0 description: The image shows the word "SYNTHES" in bold, black letters. To the left of the word is a circular logo with a design inside. A registered trademark symbol is located to the right of the word. Performance testing demonstrates that the mechanical performance of the proposed taps is comparable to that of the primary predicate device (taps) and supports substantial equivalence. ## Clinical Studies Clinical testing was not necessary for the determination of substantial equivalence. The performance data demonstrate that the mechanical performance of the proposed taps is comparable to that of the primary predicate device and supports substantial equivalence to the primary predicate device for safe and effective bone cutting in the skull. {9}------------------------------------------------ Image /page/9/Picture/0 description: The image shows the logo for SYNTHES. The logo consists of a stylized symbol on the left, followed by the word "SYNTHES" in bold, sans-serif font. A registered trademark symbol is located to the right of the word.
