The stems are gamma irradiated. #### Femoral Heads The proposed 36mm cobalt chrome femoral heads have the same 12/14 trunnion taper as the previously The proposal ounline oblines to the les 22, 26, 28 and 32 mm OD in a variety of offsets (K073068). The 36mm femoral head will have offsets of -5, -3.5, 0, +3.5 and +5mm. The prior offsets ranged from -3.5 to +12mm with the +12mm being the worst case. The heads are gamma sterilized. The proposed 36mm heads are equivalent to the Accin Hip System (K073068) in materials, design, packaging, and sterilization and equivalent to the Exactech 12/14 total hip system femoral heads in size. #### Acetabular Shells There has been no change to the existing acetabular shells. They are designed to mate with the acetabular inserts with a permanently inserted retaining ring and have three clustered holes for bone screws, if necessary. Each shell has a size that matches it to the correct inserts and are gamma sterilized. #### Acetabular Inserts Accrabular Moorts inserts (K073068). The prior inserts are offered in standard and 10° hooded variations. The proposed insorts (not over, "The prior inserts are available in 22mm, 26mm, 26mm, 26mm, and 32mm inner diameter sizes. They are designed to mate with the previously cleared acetabular shells. Each liner has a size designation that metches it to the correct mating shell component. The new 36mm acetabular liners are designed to articulate with the proposed 36mm Cardo Medical coball chrome femoral heads. The inserts are gamma sterilized. The proposed 36mm inserts are equivalent to the Accin Hip System (K073068) in materials, design, r no proposod ountil into to and equivalent to the Exactech 12/14 total hip system inserts in ID and OD. #### Bone Screws There has been no change to the existing titanium alloy bone screws cleared in K073068, which are in a There has boon no enange to are extram 15mm to 60mm. The screws are gamma sterilized. #### Summary Summary Cardo Medical, Inc. has determined that any differences in the proposed device will not impact the safety or effectiveness of the hip system for its intended use. Testing has shown that the proposed device or encourtiness of the hip typestify to the numents on total hip arthroplasty product and the proposed device is equivalent to the predicate device. All Cardo medical implant components are provided as sterile, single use only to a sterility assurance level (SAL) of 10°. ## Synopsis of Test Methods and Results: This 510(k) is for the addition of 36mm femoral heads and inserts. These heads and inserts do not r his STO(K) is for the duallion of commiss ( the 28mm femoral head component with the +12mm offset); therefore the previous testing applies to these components. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the Department of Health & Human Services - USA.
