Intended Use

Intended Use 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, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement.
  • · All forms of osteoarthritis.
  • · Patients with hips at risk of dislocation.
  • · Femoral neck fracture or proximal hip joint fracture.

The OR30 Dual Mobility System is intended for single use only. The modular OR30 Liners and Inserts are to be implanted without bone cement.

Mating components may be indicated for use without bone cement.

Device Description

The OR30 Hip System is a modular dual mobility implant system consists of diffusion hardened oxidized zirconium (OXINIUM DH) alloy liners with a highly polished zirconium oxide inner surface and a machined locking taper and backside of Zr2.5Nb alloy (F2384-10R16). The locking taper and outside profile is designed to mate with a dedicated Ti6Al4V R3 acetabular shell with OD sizes 44mm to 74mm or REDAPT Modular Press-fit acetabular shell with OD sizes 48mm to 74mm. For each assembled OR30 liner and R3 shell size from 44mm to 74mm and REDAPT Modular shell size from 48mm to 74mm, a dedicated insert is available. Inserts are made of highly crosslinked ultra-high-molecularweight polyethylene (ISO 5834-2/ASTM F648) that is irradiated with a 10 Mrad dose and remelted . These can be combined with oxidized zirconium or CoCr alloy femoral heads of sizes 22 mm (for Size 44mm-52mm) and 28 mm (for size 50mm-74mm). The final OR30 Dual Mobility construct will include an acetabular shell (with optional screws and optional screw hole covers), an OXINIUM DH Liner, a cross linked polyethylene (XLPE) Insert and a femoral head.

The purpose of this Traditional 510(k) submission is to add additional components, namely additional sizes of the OR3O Dual Mobility OXINIUM DH Liners and OR3O Dual Mobility XLPE Inserts to the existing OR30 Dual Mobility System.

This line extension will consist of two smaller size OXINIUM DH Liners and four additional XLPE inserts to allow for a wider range of implant options for physicians to choose from. The materials and manufacturing processes will be the same, with the exception of accounting for different sized implants.

AI/ML Overview

This document is a 510(k) Premarket Notification from the FDA regarding the "OR30 Dual Mobility System," a hip joint prosthesis. The provided text primarily focuses on establishing substantial equivalence to existing predicate devices based on design, materials, indications for use, and performance data, including biocompatibility and mechanical testing.

However, the document does NOT contain information about any study involving AI, human readers, or the establishment of ground truth for evaluating such a system. The "acceptance criteria" and "device performance" described in the document relate to the physical and biological characteristics of the orthopedic implant and its components, not to the performance of an AI or diagnostic system.

Therefore, I cannot extract the information required by your prompt, as it pertains to AI/diagnostic system evaluation, which is absent from this regulatory submission for a hip joint prosthesis.

The document covers:

  • Device Description: What the OR30 Dual Mobility System is, its components (liners, inserts, shells, femoral heads), and the materials used (OXINIUM DH, XLPE). It highlights that the current submission is for a line extension – adding smaller sizes of existing components.
  • Indications for Use: The medical conditions for which the hip system is intended (e.g., hip degeneration, fracture, failed previous hip surgery, osteoarthritis, risk of dislocation).
  • Comparison to Predicate Devices: A detailed comparison of the subject device (OR30 Dual Mobility System line extension) against previously cleared predicate devices, emphasizing similarities in intended use, fundamental scientific technology, materials, and indications for use.
  • Performance Data:
    • Biocompatibility: Evaluation according to ISO-10993 for permanent implants (>30 days body contact), confirming compliance with material standards (ASTM F2384-10R16 for Zr-2.5Nb alloy and ASTM F648-14 / ISO 5834-2 for XLPE). A Declaration of Conformity was provided.
    • Mechanical Testing: Listing of various ASTM and ISO standards for tests like push-out, torque to failure, lever-out, environmental fatigue, corrosion assessment, deformation, neck impingement, range of motion, and wear testing. It states that biomechanical testing and/or rationales were completed and "met the pre-determined acceptance criteria for each intended output." The submission concludes that the device does not represent a new worst-case scenario compared to predicates.
    • Non-Pyrogenicity Endotoxin Testing: Bacterial endotoxin testing was completed and met acceptable limits per FDA guidance and ANSI/AAMI ST72.

In summary, this document is a regulatory submission for a physical medical device (orthopedic implant) and does not involve AI or diagnostic imaging. Therefore, it does not contain the specific information requested in your prompt regarding AI system acceptance criteria, study design for AI evaluation, expert ground truth, or MRMC studies.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
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.(b)
