The TaperFit Hip Stem is indicated for hemi-arthroplasty when used in combination with Corin Bipolar Prosthesis hemi-arthroplasty femoral heads. The TaperFit Hip Stem is indicated for cemented, single use only. ## Device Story TaperFit Hip Stem is a highly polished, double-tapered, collarless, stainless steel femoral hip stem; features 12/14 tapered male trunnion for modular femoral head assembly. Used in cemented hip arthroplasty and hemi-arthroplasty procedures. Operated by orthopedic surgeons in clinical/hospital settings. Device provides structural support for hip joint replacement; modular design allows compatibility with Corin Eurocone and Trinity CoCrMo femoral heads or Corin Bipolar Femoral Heads. Benefits include pain relief and restoration of hip function for patients with degenerative or traumatic hip conditions. ## Clinical Evidence No clinical data. Bench testing only, including FEA, mechanical fatigue, static, rotational torque, fretting, corrosion, and range of motion testing, previously submitted in K142761, K992234, and K003666. ## Technological Characteristics Highly polished, double-tapered, collarless femoral stem. Material: Wrought high nitrogen stainless steel (ISO 5832-9). Includes PMMA stem centralizer. 12/14 tapered male trunnion. Sizes 0-4; offsets 50mm, 45mm, 38mm, and CDH 36mm. Cemented, single-use. ## Regulatory Identification A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027). ## Predicate Devices - Corin TaperFit Hip Stem ([K142761](/device/K142761.md)) - Corin Taper-Fit Hip Stem ([K992234](/device/K992234.md)) - Corin Taper-Fit Hip Stem ([K003666](/device/K003666.md)) ## Reference Devices - Corin Eurocone ([K003666](/device/K003666.md)) - Trinity CoCrMo modular femoral heads ([K093472](/device/K093472.md), [K110087](/device/K110087.md), [K122305](/device/K122305.md), [K123705](/device/K123705.md), [K130128](/device/K130128.md), [K130343](/device/K130343.md), [K131647](/device/K131647.md)) - Corin Bipolar Femoral Head ([K925897](/device/K925897.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Device Description: The TaperFit Hip Stem is a highly polished, double tapered, collarless, stainless steel femoral hip stem featuring a 12/14 tapered male trunnion for assembly with modular femoral head components. The stem is manufactured from stainless steel in accordance with ISO 5832-9 -Implants for surgery -- Metallic materials -- Part 9: Wrought high nitrogen stainless steel and is provided with a polymethylmethacrylate (PMMA) Stem Centralizer. The stem is designed to be used in conjunction with Corin Eurocone (E100.XXX cleared in K003666) and Trinity CoCrMo modular femoral heads (E321.XXX cleared in K093472, K110087, K122305, K123705, K130128, K130343 and K131647). The stem is available in sizes, 0 through 4 with 3 offsets 50mm, 45mm, and 38mm, as well as a CDH option with a 36mm offset. The TaperFit Hip Stem was originally cleared in K142761. This submission is being made to modify the indications for use to include hemi-arthroplasty when used with previously cleared Corin hemi-arthroplasty femoral heads as compatible components. The Corin CoCr Modular 26mm heads (E100.X26) have been cleared as compatible components of the Taper-Fit Hip stem (K003666). The Corin CoCr Modular 26mm heads (E100.X26) are part of the construct of the bipolar heads. Included in this submission is the Corin Bipolar Femoral Head (K925897) as a compatible component, which is indicated for hemi-arthroplasty. ## 10. Intended Use / Indications: The TaperFit Hip Stem is indicated for the relief of pain and restoration of hip function following the effects of femoral neck fracture, osteo, rheumatoid and inflammatory arthritis, post-traumatic disease effects, avascular necrosis and total hip revision. The TaperFit Hip Stem is indicated for hemi-arthroplasty when used in combination with Corin Bipolar Prosthesis hemi-arthroplasty femoral heads. The TaperFit Hip Stem is indicated for cemented, single use only. # 11. Summary of Technologies / Substantial Equivalence: The TaperFit Hip Stem, subject of this submission, and the predicate TaperFit Hip Stem (K142761) are identical in design, materials, coating, and sizes and similar in terms of intended use/indications for use. Additionally, the TaperFit Hip Stem, subject of this submission, and the predicates, Taper-Fit Hip Stem (K992234 and K003666) are identical in materials, and coating, and similar in terms of design, sizes, and intended use/indications for use. Based on these similarities, Corin believes that the TaperFit Hip Stem is substantially equivalent to the predicate devices. # 12. Non-Clinical Testing: {5}------------------------------------------------ Non-clinical testing and analysis included FEA, mechanical fatigue testing, static testing, rotational torque testing, fretting and corrosion testing, and range of motion testing. This testing was performed and submitted in the previous TaperFit and Taper-Fit Hip Stem submissions (K142761, K992234, and K003666). # 13. Clinical Testing: Clinical testing was not necessary in this Traditional 510(k). --- **Source:** [https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/JDI/K153725](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/JDI/K153725) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
