The document describes a mechanical implant (total hip components) and its performance in wear testing. There is no mention of software, algorithms, image processing, or any terms related to AI/ML.
Yes.
The device is described as a "Total hip components" aiming to rehabilitate hips damaged by various conditions like trauma, inflammatory joint disease, or noninflammatory degenerative joint disease, which aligns with the definition of a therapeutic device.
No
The device description indicates it is a total hip component, which is a prosthesis used in surgery for damaged hips. Its performance studies focus on wear rate, not diagnosis.
No
The device description and performance studies clearly indicate this is a physical implant (acetabular components) and not a software-only device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used in vivo (within the body) for surgical implantation to treat hip joint problems. IVDs are used in vitro (outside the body) to examine specimens from the human body.
- Device Description: The description refers to "Acetabular Components," which are parts of a hip implant.
- Anatomical Site: The anatomical site is the "Hip," indicating an internal body part.
- Performance Studies: The performance studies describe testing in a "multiaxial hip joint simulator," which simulates the mechanical forces on an implanted device, not a diagnostic test.
- Key Metrics: The key metric is "reduction in volumetric wear rate," which is a measure of the durability of an implant, not a diagnostic performance metric like sensitivity or specificity.
All the information provided points to a surgically implanted medical device, not an in vitro diagnostic device.

Intended Use / Indications for Use
Total hip components are individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory joint disease such as rheumatoid arthritis, or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses such as osteoarthritis; avascular necrosis; traumatic arthritis; slipped capital epiphysis; fused hip; fracture of the pelvis and diastrophic variant; old, remote osteomyelitis with an extended drainage-free period; nonunion; femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; femoral osteotomy, or Girdlestone resection; fracture dislocation of the hip; and correction of deformity.

§ 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)

B. DEVICE DESCRIPTION
The intended use, type of interface, and design features of The Reflection® Cross-linked UHMWPE Acetabular Components are substantially equivalent to the subject identical predicate counterparts fabricated from conventional UHMWPE.
C. SUBSTANTIAL EQUIVALENCE INFORMATION
The Reflection® Cross-linked UHMWPE Acetabular Components are substantially equivalent to the subject identical predicate counterpart. The intended use, material, and design features of The Reflection® Cross-linked UHMWPE Acetabular Components are substantially equivalent to predicate competitive devices.
While the Reflection® Cross-linked UHMWPE Acetabular Components are not identical to all of the predicates, any differences that may exist do not significantly affect the safety and effectiveness.
D. WEAR CLAIMS
The following marketing claims will be made for the Reflection® Cross-linked UHMWPE Acetabular Components:
-
- Meets all ASTM F648 minimum standards.
-
- No free radicals detectable when analyzed by the ESR technique of the final product. (The detection limit is approximately 1013 spins/gram).
-
- No detectable oxidation as measured by FTIR up to 21 days of accelerated aging at 74℃.
-
- 91.9% reduction in volumetric wear rate versus the identical predicate counterpart fabricated from conventional UHMWPE. Testing was performed in a multiaxial hip joint simulator for min. 3.8 million - max. 5.1 million cycles per individual test using a 32mm wrought CoCr head articulating counterface, a 32mm ID, 56mm OD, minimum thickness 7mm liner with the 20 degree overhang design and Hyclone bovine calf serum as a lubricant.
E. SUMMARY OF TECHNOLOGICAL COMPARISON
The intended use, material, type of interface, and design features of The Reflection® Cross-linked UHMWPE Acetabular Components are similar to their predicate component counterparts. The raw material used in manufacturing both the subject and predicate devices are UHMWPE per ASTM F-648. The modification to the manufacturing process of this polyethylene resulted in a higher cross-linked polyethylene. The safety and effectiveness of this cross-linked polyethylene in acetabular applications, as well as the proposed wear claims, are adequately supported by the substantial equivalence information, materials data, and testing results provided within this Premarket Notification.
