The device is intended for prescription use only. ## Device Story Corin Optimom Modular Head is a polished, truncated sphere femoral head prosthesis; functions as a hemi-arthroplasty component. Device features internal female taper modified for compatibility with 12/14 male taper femoral hip stems. Used in orthopedic surgery for patients with femoral head pathology and normal acetabulum. Implanted by surgeons; provides articulation for hip joint. Benefits include pain relief and restoration of function for patients with arthritis or femoral neck fractures. Substantial equivalence established via design, material, and mechanical testing comparisons to predicate modular heads. ## Clinical Evidence No clinical data. Substantial equivalence determined via non-clinical bench testing including fatigue, rotational torque, axial pull-off, and fretting corrosion analysis. ## Technological Characteristics Polished, truncated sphere femoral head; Cobalt-Chrome alloy (ASTM F75); diameters 40-56mm; internal female taper for 12/14 male taper compatibility. Mechanical device; no software or electronics. ## Regulatory Identification A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth. ## Predicate Devices - Corin Unipolar Modular Head ([K063791](/device/K063791.md)) - Corin Taperfit Total Hip System ([K003666](/device/K003666.md)) - Corin Tri-Fit Femoral Stem ([K010243](/device/K010243.md)) ## Reference Devices - Trinity Modular Heads ([K110087](/device/K110087.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Device Description: The Corin Optimom Modular Head is a polished, truncated sphere with a high tolerance internal female taper. It is a device modification of the internal female taper of the Corin Unipolar Modular Heads (K063791) to provide for compatibility with an additional range of Corin femoral hip stem designs with a 12/14 male taper. The materials and dimensions of the internal female taper are substantially equivalent to the CoCr Modular Heads cleared in K003666 and K010243 and the Trinity Modular Heads cleared in K110087. The Optimom Modular Head is manufactured from Cobalt-Chrome alloy conforming to {1}------------------------------------------------ ASTM F75 and is available in diameters ranging from 40-56mm with a variety of offsets. - 8. Intended Use / Indications: The Corin Optimom Modular Head is indicated for hemi-arthroplasty in cemented and uncemented primary or revision femoral stem applications whose indications include procedures for patients suffering pain and disability due to osteoarthritis, rheumatoid arthritis, avascular necrosis of the femoral head, femoral neck fracture and abnormalities where the major pathology affects the femoral head, the acetabular cavity is normal and acetabular replacement is either undesirable or not required. The device is intended for prescription use only. - 9. Summary of Technologies/Substantial Equivalence: The Optimom Modular Heads have the same intended use and indications as the Corin Unipolar Modular Heads (K063791). The range of diameters available for the Optimom Modular Heads is within the range cleared for the predicate Unipolar Modular Heads and the device design is similar to the Unipolar Heads with the only modification of the internal female taper. The Optimom Modular Heads are manufactured from the same material as the predicates Unipolar Modular Heads, CoCr Modular Heads (K003666, K010243) and Trinity Modular Heads (K110087). The design and dimensions of the internal female taper of the Optimom Modular Heads are the same as the internal female taper of the predicates CoCr Modular Heads and Trinity CoCr Modular heads. Based upon these similarities, the Optimom Modular Heads are believed to be substantially equivalent to the predicate devices. ### 10. Non-Clinical Testing: Non-clinical testing conducted to demonstrate substantial equivalence includes a comparison of the designs, materials, intended use, indications and dimensions of the Corin Optimom Modular Head to the predicate devices Fatigue, rotational torque, axial pull off, and fretting corrosion were conducted. - 11. Clinical Testing: Clinical testing was not necessary to determine substantial equivalence between the Corin Optimom Modular Heads and the predicate devices. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the Department of Health and Human Services (HHS) in the United States.
