Device Description

Taperloc® Complete Size 4mm Stems
The Taperloc® Complete Size 4mm stems will combine the design features of the Taperloc® Complete fulllength stems (K101086 and K103755) and the shortened design of the new Taperloc® Complete Microplasty, K110400. This submission is extending the implant size range to 4mm for the Full Profile (full-length and Microplasty), the Reduced Distal Profile (full-length and Microplasty), and the Traditional Reduced Distal Profile (full-length only). The design characteristics of the size 4mm full-length stems and Microplasty stems are identical to the Taperloc® Complete implants (K101086, K103755 and K110400); this is simply a line extension of our current offerings. These characteristics include: trapezoidal neck design, short taper, 133° neck angle, same material properties of the stem and plasma spray, a reduced profile distal stem, and an updated insertion/extraction hole.

Taperloc® Complete XR 123° Stems
The Taperloc® Complete XR 123° implants incorporate all the benefits of the Taperloc® Complete system, both full-length and Microplasty, as mentioned above, with a single offset neck option for the Full Profile and the Reduced Distal Profile. The only change is the 123° offset option, which was developed to reduce vertical offset (leg length), while maximizing horizontal offset. This option is supported through additional mechanical testing.

AI/ML Overview

The provided text describes mechanical testing conducted on the Taperloc® Complete Size 4mm and XR 123° hip stems to demonstrate their substantial equivalence to predicate devices. This is a submission for a medical device (hip prosthesis), and the "acceptance criteria" and "study" refer to mechanical fatigue testing rather than a clinical study evaluating AI performance.

Here's an analysis of the provided information:

1. Table of Acceptance Criteria and Reported Device Performance

Test NameAcceptance Criteria (Set by)Reported Device Performance
Taperloc® Complete 4mm 133°
Proximal Pot Fatigue Test (MT6461)10 million cycles to 120lbs (ASTM F2068-03)Passed. 6 stems tested, all passed 10 million cycles.
Distal Pot Fatigue Test (MT6540)5 million cycles to 67lbs - 517lbs (FDA guidance)Passed. 6 stems tested, all passed 5 million cycles.
Taperloc® Complete XR 123°
Proximal Pot Fatigue Test (MT6579)10 million cycles to 120lbs - 1,200lbs (ASTM F2068-03)Passed. 6 stems tested, all passed 10 million cycles.
Distal Pot Fatigue Test (MT6609)5 million cycles to 67lbs - 517lbs (ASTM 1612-95 (Reapproved 2005))Passed. 6 stems tested, all passed 5 million cycles.

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size: 6 stems were used for each individual test (Proximal Pot Fatigue and Distal Pot Fatigue) for both the 4mm 133° and XR 123° models.
  • Data Provenance: The tests are explicitly referred to as "Non-Clinical Testing." They are laboratory-based mechanical fatigue tests, not human subject studies. Therefore, data provenance in terms of country of origin or retrospective/prospective is not applicable in the same way it would be for clinical data.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. This is a mechanical engineering study, not one using expert human interpretation for "ground truth." The "ground truth" here is the physical performance of the device under simulated physiological conditions.

4. Adjudication Method for the Test Set

Not applicable. This is mechanical testing, not a study requiring adjudication of expert opinions.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This document is for a medical device (hip prosthesis) and its mechanical performance, not an AI-powered diagnostic or assistive tool.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

Not applicable. This document is for a medical device (hip prosthesis) and its mechanical performance, not an AI-powered algorithm.

7. The type of ground truth used

The "ground truth" for these mechanical tests is the physical failure or survival of the device when subjected to specified loads for a defined number of cycles, as per established ASTM standards and FDA guidance. This is an objective, measurable outcome from engineered testing.

8. The sample size for the training set

Not applicable. There is no concept of a "training set" in this non-clinical mechanical testing context. The tests are designed to validate the mechanical properties of the final device, not to train an algorithm.

9. How the ground truth for the training set was established

Not applicable. See point 8.

Taperloc® Complete Size 4mm stems and the XR 123° stems have remained unchanged from the predicate Biomet Taperloc® Complete Stems (K101086, K103755, and K110400). The trunnion for the XR 123° has been modified to include a reduced neck angle of 123°, as compared to 133° of the predicate Taperloc® Complete Stems (K101086, K103755 and K110400). The trapezoidal design, taper junction and fine sisal buff surface finish of the Taperloc® Complete 4mm and the XR 123° stems are the exact same used with the predicate Biomet Taperloc® Complete Stems (K101086, K103755 and K110400). Additionally, the updated insertion/extraction hole is identical to the Taperloc® Complete stem predicates (K101086, K103755 and K110400). Stem lengths are within the range of the legally marketed predicates.

Non-Clinical Testing:

Taperloc_4mm 133"

MT6461-Taperloc Complete 4mm 133° Proximal Pot Fatigue Test

The proximal pot test was conducted on the 4mm High Offset Taperloc® Complete Microplasty Stems that included the new design modifications, determined to be worst case by Finite Element Analysis (FEA). Six stems, combined with +12 modular heads, were tested and passed the 10 million cycles to 120lbs. The results meet the acceptance criteria set forth by ASTM F2068-03. Since the worst-case 4mm 133° High Offset passed the mechanical test, it can be expected that the 4mm 133° Standard Offset implant will also pass this proximal pot mechanical test.

MT6540-Taperloc Complete 4mm 133° Distal Pot Fatigue Test

Six 4mm 133° Standard Offset Microplasty Stems represented the worst-case, as determined by FEA, simulating the distal pot loading scenario. (The worst-case stress conditions were shown in the High Offset stems, but since the High Offset stems are not included in this submission, the second worst stem, the 4mm 133 Standard Offset was tested.) All six stems tested passed 5 million cycles to

67lbs - 517lbs, meeting acceptance criteria as set forth in FDA guidance.

Taperloc Complete XR 123°

MT6579—Taperloc Complete XR 123° Proximal Pot Fatigue Test

Based on the FEA results of the twelve smallest stem sizes, as expected, the smallest stem was the worst-case. FEA showed that both Full-Length sizes and Microplasty sizes were found to perform the same, because the only differences between the two are their distal geometries which are potted deep in the potting media and have no effect on the strength of the proximal geometry. Therefore, six, of the 4mm XR 123° Microplasty stems, combined with +12 modular heads were tested. All six stems passed 10 million cycles to 120lbs -1,200lbs. These results meet the acceptance criteria set forth by ASTM F2068-03, and it can be said that the entire Taperloc Complete XR 123° hip system will withstand the same loading conditions.

MT6609—Taperloc Complete XR 123° Distal Pot Fatigue Test

As determined by FEA, the worst-case stem is the combination of the smallest diameter stem (4mm) with a large horizontal offset and low vertical offset, combined with a femoral head that has the highest available offset (28mm +12). The XR 123° worst-case stem was potted at the same level as the other Taperloc Complete stems (K101086, K103755, K110400) relative to the intersection of the medial curve and resection level. The first round of testing encountered some issues due to potting media breakdown. After this problem was corrected, six samples withstood the loading for 5,000,000 cycles. Upon the completion of the test, the stems were found to be in their original condition. All six stems tested 5 million cycles to 67lbs - 517lbs, meeting acceptance criteria as set forth ASTM 1612-95 (Reapproved 2005).

§ 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)
Classification. Class II.
