No
The document describes a physical medical device (an acetabular shell for hip replacement) and its materials and mechanical properties. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is described as an acetabular shell intended for use in total hip arthroplasty to alleviate pain and restore function, which clearly defines it as a therapeutic device.
No
This device is an acetabular shell, which is a component of a total hip replacement prosthesis, used to alleviate pain and restore function. It is a therapeutic device, not a diagnostic one.
No
The device description clearly details a physical, metallic acetabular shell with coatings, intended for surgical implantation. This is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for use in "primary and revision total hip arthroplasty to alleviate pain and restore function." This is a surgical procedure performed in vivo (within the body), not a diagnostic test performed in vitro (outside the body).
- Device Description: The description details a metallic acetabular shell with coatings, designed to be implanted in the hip joint. This is consistent with a surgical implant, not a diagnostic device.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze biological samples (like blood, urine, or tissue) or to provide diagnostic information about a patient's condition. Its purpose is to replace a damaged joint.
- Performance Studies: The performance studies focus on the mechanical properties and biocompatibility of the implant, which are relevant for a surgical device, not a diagnostic one.
In summary, the Tritanium® Peri-Apatite™ Acetabular Shell is a surgical implant used in hip replacement surgery, not a device used for in vitro diagnostic testing.
N/A
Intended Use / Indications for Use
The Tritanium® Peri-Apatite™ Acetabular Shell is a sterile, single-use device intended for use in primary and revision total hip arthroplasty to alleviate pain and restore function.
The indications for use of the total hip replacement prostheses include:
- Painful, disabling joint disease of the hip resulting from: non-inflammatory degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis, or late stage avascular necrosis.
- Revision of previous failed femoral head replacement, shell arthroplasty or other procedure.
- Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.
- Where bone stock is of poor bone quality or inadequate for other reconstructive techniques as indicated by deficiencies of the acetabulum.
Additional indications for use when using constrained liners: The device is indicated for use as a component of a total hip prosthesis in primary and revision patients at high risk of hip dislocation due to a history of prior dislocation, bone loss, joint or soft tissue laxity, neuromuscular disease, or intraoperative instability.
Additional indications for use when using modular dual mobility (MDM) liners: The device is indicated for use as a component of a total hip prosthesis and include:
- Noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis;
- Rheumatoid arthritis;
- Correction of functional deformity;
- Revision procedures where other treatments or devices have failed;
- Treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; and
- Dislocation risks
The MDM liners are intended for cementless use only. The acetabular shell is intended for cementless use only.

Device Description
The Tritanium® Peri-Apatite ™ acetabular shells are available in both solid backed and cluster screw-hole designs for cementless, biologic fixation. The Howmedica Osteonics Tritanium® Peri-Apatite™ Acetabular Shell consists of a hemispherical, metallic acetabular shell with a Tritanium® (CPTi) coating referred to as a Particle Sintered Foam (PSF) coating with an overlying Peri-Apatite coating (precipitated calcium phosphate coating). The Peri-Apating process is identical to that cleared in K971206 but to a greater thickness range of 35-75 microns. The Tritanium® CPTi PSF coating originally manufactured from material conforming to ASTM F67 was modified to conform to ASTM F1580. The dual coating (Peri-Apatite™ overlying the PSF coating) at the thickest specification met the definition of a porous coating per 21 CFR 888.3358 with no additional claims over biologic fixation. The dome hole plugs are optional devices which are available to seal the Howmedica Osteonics Tritanium® Acetabular Shells. The plugs are to be threaded into the dome holes of the shell.
The shells will be available in sizes 44-72 mm outside diameter (OD) in 2 mm increments. The acetabular shells are forged from Ti-6Al-4V alloy per ASTM F136; the Tritanium® coating is fabricated from Commercially Pure Titanium per ASTM F1580; and the Peri-Apatite™ coating is a precipitated calcium phosphate coating per ASTM F-1609.
The Tritanium® Peri-Apatite™ Acetabular Shells are compatible with polyethylene Trident® inserts, constrained liners and modular dual mobility liners. The subject shells have an identical insert locking mechanism to that employed with compatible Tritanium acetabular shell system predicates. All shells are single use devices. The outer surface of the acetabular shell has the identical geometry as the predicate Tritanium® Acetabular Shell System determined substantially equivalent via 510(k) K081171.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Testing: Non-clinical laboratory testing was performed to determine substantial equivalence. Non-clinical testing was provided as outlined in the FDA Guidance Document entitled "Guidance Document for Testing Orthopedic Implants with Modified Metallic Surfaces Apposing Bone or Bone Cement (28 April 1994)" for the underlying Tritanium surface which included additional testing on the CPT Tritanium conforming to ASTM F1580 in terms of static tensile, static shear and shear fatigue bond strength testing. The dual coating/surface was characterized per the FDA Guidance document entitled "510(k) Information Needed for Hydroxyapatite Coated Orthopaedic Implants (February 20, 1997)." All characterization parameters on the final dual coating/surface were provided. The NIST SRM 2910(a) material was used as a comparator for the Xray diffraction, dissolution rate and solubility product parameters. The dual coating/surface underwent additional characterization to demonstrate that the definition of porosity was met per 21 CFR 888.3358 at the thickest specification. Additionally, four-point bend fatiguing, abrasion, and fatigue strength of the subject acetabular shell were performed. Third body wear information was provided to address the theoretical risk. All of the observed results indicate that the subject Tritanium® Peri-Apatite™ Acetabular Shell System is substantially equivalent to devices currently cleared for marketing.
Clinical Testing: None provided as a basis for substantial equivalence.

§ 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)
