Designed to mate with existing acetabular shells (R3 or REDAPT) and femoral heads (oxidized zirconium or CoCr). Implanted without bone cement in primary or revision total hip arthroplasty. Provides two articulating surfaces within the joint space to improve stability and reduce dislocation risk. Used by orthopedic surgeons in clinical/OR settings. Output is a reconstructed hip joint interface; assists surgeons in restoring joint function and mobility for patients with degenerative or traumatic hip conditions. ## Clinical Evidence Bench testing only. No clinical data provided. Performance verified via mechanical testing including push-out, torque-to-failure, lever-out, environmental fatigue, deformation, wear, pull-out, neck impingement, range of motion, and jump distance. Biocompatibility evaluated per ISO 10993. Bacterial endotoxin testing performed per ANSI/AAMI ST72. ## Technological Characteristics Modular hip prosthesis. Liner: Zr-2.5Nb alloy (ASTM F2384). Insert: 10Mrad irradiated/remelt-annealed XLPE (ASTM F648, ISO 5834-2). Mating components: Ti 6Al 4V acetabular shells. Articulation: Dual mobility (two articulating surfaces). Sterilization: Not specified. Connectivity: None (mechanical implant). ## Regulatory Identification A hip joint metal/polymer/metal semi-constrained porous-coated uncemented 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement. ## Predicate Devices - POLARCUP Dual Mobility System ([K110135](/device/K110135.md)) - REFLECTION Hip System ([K071160](/device/K071160.md)) - BH Dual Mobility System ([K171934](/device/K171934.md)) - OXINIUM DH Femoral Heads ([K161233](/device/K161233.md)) ## Reference Devices - R3 Shell ([K092386](/device/K092386.md)) - REDAPT Modular Shell ([K182109](/device/K182109.md)) - OXINIUM Femoral Heads ([K110101](/device/K110101.md)) - Cobalt Chrome Femoral Heads ([K963509](/device/K963509.md)) - Cobalt Chrome Femoral Heads ([K963486](/device/K963486.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The OR30 Hip System is a modular dual mobility implant system. The system consists of diffusion hardened, oxidized zirconium alloy liners with a highly polished inner surface of zirconia and a machined locking taper and backside of Zr-2.5Nb alloy. The locking taper and machined outside profile is designed to mate with a dedicated Ti 6Al 4V R3 or REDAPT Modular Press-fit acetabular shell with OD sizes 48mm to 74mm. For each assembled OR30 Liner and R3 and REDAPT Modular Shell size from 48mm to 74mm, a dedicated plastic insert made of highly crosslinked ultrahigh-molecular-weight polyethylene (10Mrad irradiated and remelt-annealed UHMWPE (XLPE) according to ISO 5834-2/ASTM F648) is available. These can be combined with oxidized zirconium or CoCr alloy femoral heads of sizes 22mm (for size 48mm-52mm) and 28mm (for size 54mm-74mm). The final OR30 Dual Mobility construct will include an acetabular shell, an OXINIUM DH Liner, an XLPE Insert and a femoral head. The purpose of this 510(k) submission is to add additional options of dual mobility implants to the Smith & Nephew collection of hip implants. #### INDICATIONS FOR USE V. ## Intended User The OR3O Dual Mobility System is intended for use in primary and revision total hip arthroplasty in skeletally mature patients. ## Indications - Advanced degeneration of the hip joint as a result of degenerative, post-traumatic, or rheumatoid . arthritis. - Fracture or avascular necrosis of the femoral head. . - Failure of previous hip surgery: joint reconstruction, internal fixation, arthrodesis, . hemiarthroplasty, surface replacement arthroplasty, or total hip replacement. - All forms of osteoarthritis. . - .

PERFORMANCE DATA The following performance data are provided in support of the substantial equivalence determination. # Biocompatibility The biocompatibility evaluation for the OR3O Dual Mobility Implants and Instruments was conducted in accordance with FDA's Draft Guidance for Industry and FDA Staff "Use of International Standard ISO-10993, Biological Evaluation of Medical Devices Part 1: Evaluation and Testing Within a Risk Management Process". The subject OR3O Dual Mobility Implants are permanent implants and will be classified as permanent, >30 day body contact according to ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a Risk Management Process". The subject OR3O Dual Mobility Liners are manufactured from Zr-2.5Nb alloy materials in accordance with the following ASTM standard: F2384- 10R16 Standard Specification for Wrought Zirconium-2.5Niobium Alloy for Surgical Implant Applications (UNS R60901). {7}------------------------------------------------ The subject OR30 Dual Mobility Inserts are manufactured from identical polyethylene XLPE materials as the predicate device, in accordance with the following standards: ASTM F648-14 Standard Specification for Ultra-High-Molecular-Weight Polyethylene Powder and Fabricated Form for Surgical Implants and ISO 5834-2 - Implants for surgery. Ultra-high-molecular-weight polyethylene. Moulded forms. Instruments to support the OR3O Dual Mobility Implants have also been assessed for biocompatibility. The device specific implant OR30 Trial Liners have been manufactured from Radel PPSU (polyphenylsulfone) and the OR30 Trial Inserts are manufactured from Radel PPSU (polyphenylsulfone). A biocompatibility report evaluation has been completed and summary rationales including Declaration of Conformity's have been provided for the subject OR30 Dual Mobility System. # Mechanical testing Smith & Nephew has evaluated the subject OR3O Dual Mobility System to demonstrate substantial equivalence to the predicate POLARCUP Dual Mobility K110135 (S.E. 10/14/2011) and REFLECTION Hip System – K071160 (S.E. 10/05/2007) and determined that the subject devices do not represent a new worst case.
