Proprietary Name: | Corin Trifit TS Hip | | | - 5. Common Name: Hip Prosthesis 6. Classification Name: Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis (21CFR 888.3353) > Hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis (21CFR 888.3390) Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis (21CFR 888.3360) ## 7. Legally Marketed Devices to which Substantial Equivalence is claimed: - Biomet Laterlized Taperloc® MicroplastyTM Femoral Components (K062994) - DePuy Titanium Tri-Lock Hip Stem (K010367) . - " DePuy Tri-Lock Bone Preservation Stem (K073570) - " Corin Metafix Hip Stem with Hemi-Arthroplasty (120362) - · Corin Trinity Acetabular System (K093472) #### 8. Device Description: The Corin TriFit TS Hip is a double tapered-wedge blade stem design manufactured from Ti6Al4V Titanium alloy (ASTM F-136-08) with a layer of commercially pure titanium (BS ISO 5832-2: 1999) and calcium phosphate(BONIT®)coating(ASTM F1609-08) applied. The TriFit TS Hip is available in a range of sizes in standard and {1}------------------------------------------------ lateralized offsets with a 127° CCD angle. The device isintended to be used with Corin 12/14 modular taper heads. The TriFit TS Hip is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients wherethere is evidence of sufficient sound bone to seat and support the components. ### 9. Intended Use / Indications: The indications for the Corin TriFit TS Hip as a total hip arthroplasty, and when used in combination with a Corin hemi atthroplasty head, as a hip hemi-arthroplasty, include: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular 0 necrosis - Rheumatoid arthritis O - Correction of functional deformity O - Treatment of non-union, femoral neck and trochanteric fractures of the proximal 0 femur - Developmental dysplasia of the hip (DDH) or congenital dysplasia of the hip (CDH) 0 The TriFit TS Hip is intended for cementless use only. ## 10. Summary of Technologies/Substantial Equivalence: The TriFit TS Hipis similar to the Biomet Taperloc® MicroplastyTM (K062994) and the DePuy Tri-Lock (K010367, K073570) hip stems in terms of materials, sizes, designs, performance, intended use and indications for use. It is identical to the Corin Metafix Hip Stem (K120362) in terms of intended use and indications and similar in materials. The coating of titanium plasma spray with a layer ofcalcium phosphate(BONIT®) is similar to the coating for the Corin Trinity Acetabular System.(K093472) in terms of materials and performance. Based on these similarities, the TriFit TS Hip is believed to be substantially equivalent to the predicate devices. #### 11. Non-Clinical Testing: Non-clinical testing conducted to demonstrate substantial equivalence is consistent with "Guidance for Industry and FDA Staff Non-clinical Information for Femoral Stem Prosthesis" and includes: femoral hip stem fatigue (ISO 7206-4: 2010), femoral stem neck fatigue (ISO 7206-6: 1992 and ASTM F2068-03 Standard Specification for Femoral Prostheses andRange of Motion analysisconsistent with ISO 21535:2009. All 6 stems passed hip stem fatigue testing for 5 million cycles (mc) at 2.3 kN meeting the acceptance criteria. All 6 stems passed stem neck fatigue for 10 mc at 5.34 kN, meeting {2}------------------------------------------------ K)2.1563 # 3/3 the acceptance criteria. The minimum Range of Motion passed its simulation, meeting the acceptance criteria. The underlying plasma sprayed CPTi coating thickness was tested for porosity, pore size, thickness, surface roughness, mechanical strength (static tensile, static shear, shear fatigue) and taper abrasion in line with the requirements of 'Guidance Document for Testing Orthopedic Implants With Modified Metallic Surfaces Apposing Bone Or Bone Cement'. The calcium phosphate coating (BONIT®) applied by electrochemical deposition to the CPT coating was characterized per FDA's "510(k) Information needed for Hydroxyapatite Coated Orthopedic Implants." The dual nonporous coating (calcium phosphate coating overlying the CPTi coating) underwent additional testing in order to determine the thickness, porosity and pore diameter of the combined coating in accordance with ASTM F1854, as well as bending fatigue testing. ## 12. Clinical Testing: Clinical testing was not necessary to determine substantial equivalence between the additional components of the Corin TriFit TS Hip stem and the predicate devices. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
