Device Description

The Minima S System is intended for partial or total hip arthroplasty in cementless use. It is a monolithic collarless stem available in 9 sizes (#4-#12) in standard and lateralized versions.
When used in total hip arthroplasty Minima S stems are coupled to:

Biolox Delta femoral heads (object of this submission) or Limacorporate Femoral Heads (K112158) articulating with Limacorporate Cemented Cups (K112158) or
Biolox Delta heads (object of this submission) or Limacorporate Femoral Heads (K112158) articulating with Delta TT Acetabular System (K112898).
When used in partial hip arthroplasty the Minima S femoral stem is coupled to Lock Bipolar Heads (Limacorporate K112158).
The Minima S stem is made of Ti6Al4V and it has a plasma sprayed titanium coating in the proximal area (ASTM F1472 - ISO 5832-3). The stem is characterized by a 12/14 conical taper to be coupled to Limacorporate Femoral Heads, Biolox Delta femoral heads or Lock Bipolar Heads. In addition necks are lowered to reduce accidental contact between stem and acetabular cups and they are mirror-polished to reduce abrasion of the UHMWPE cups in case of abnormal contact. The stem has a rectangular section and is characterized by a "V" shaped A-P profile to improve adaptability to the most common bone morphologies and to facilitate insertion of the stem in the canal.
The Minima S System stems is available in standard and lateralized versions with different CCD angles (131° and 134°), offsets and stem lengths.
Biolox Delta Heads devices are used by surgeons to replace the head of the femur during total or partial hip surgery. They are characterized by a spherical shape and are coupled with the acetabular cup (K112158, K112898) inserted in the acetabulum, in total hip replacement, or with Lock Bipolar Heads (K112158) in partial hip replacement.
Biolox Delta heads are coupled with the Minima S stems by means of a 12/14 Morse taper. Biolox Delta heads are made of Biolox Delta ceramic and are available with 28, 32 and 36 mm of diameters and in sizes (offsets) S, M, L and XL (XL size available only for head size 36).

AI/ML Overview

This document is a 510(k) premarket notification for the Minima S System, a hip replacement device. It primarily focuses on demonstrating substantial equivalence to previously marketed devices rather than presenting the results of a primary clinical study for the Minima S System itself. As such, information regarding acceptance criteria, device performance, and study design elements typically found in a clinical trial report is not present in this document for the Minima S System.

However, the document does describe non-clinical testing performed to demonstrate substantial equivalence. Based on the provided text, here's an analysis of the relevant sections, acknowledging that many requested fields cannot be filled due to the nature of this submission:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Non-Clinical)	Reported Device Performance (Non-Clinical)
Minima S System (Stems):
Fatigue resistance according to ISO 7206-6	Tests results demonstrated the device's ability to perform under expected clinical conditions.
Fatigue resistance according to ISO 7206-4	Tests results demonstrated the device's ability to perform under expected clinical conditions. (Included evaluation of pull-out force for ceramic heads).
Titanium Plasma Spray coating conformity to FDA guideline and referenced standards	Coating was characterized to verify conformity.
Biolox Delta Heads:
Burst strength according to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip Systems	Tests results demonstrated the device's ability to perform under expected clinical conditions.
Fatigue according to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip Systems	Tests results demonstrated the device's ability to perform under expected clinical conditions.
Post-fatigue evaluation according to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip Systems	Tests results demonstrated the device's ability to perform under expected clinical conditions.

Explanation: The document states that the non-clinical tests demonstrated the devices' ability to perform under expected clinical conditions, implying that the acceptance criteria for these tests were met. However, the specific quantitative pass/fail criteria (e.g., maximum deflection, number of cycles survived, minimum pull-out force values, specific burst pressure) are not detailed in this summary.

Information Not Available or Not Applicable Based on the Provided Document:

The following information is specifically requested for "the study that proves the device meets the acceptance criteria." Since this document details a 510(k) submission based on substantial equivalence and non-clinical testing, and explicitly states "Clinical testing was not necessary," most of the requested fields related to clinical studies, human reader performance, and ground truth establishment from patient data are not applicable and are therefore left blank or marked as "N/A."

Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Sample Size: Not specified for the non-clinical tests. Non-clinical mechanical tests typically use a smaller number of physical samples (e.g., n=3 or n=6 per test condition) rather than a "test set" of patient data.
- Data Provenance: N/A (Non-clinical mechanical testing).
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: N/A (No clinical test set requiring expert ground truth in this document).
Adjudication method (e.g. 2+1, 3+1, none) for the test set: N/A (No clinical test set requiring adjudication in this document).
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 refers to a hip replacement system, not an AI diagnostic device.
If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This document refers to a hip replacement system, not an AI diagnostic device.
The type of ground truth used (expert consensus, pathology, outcomes data, etc): N/A. For the non-clinical tests, the "ground truth" would be the engineering specifications and performance limits defined by the referenced ISO standards and FDA guidance documents.
The sample size for the training set: Not applicable. This document refers to non-clinical testing for a physical medical device, not a machine learning model.
How the ground truth for the training set was established: Not applicable. This document refers to non-clinical testing for a physical medical device.

Description:

The Minima S System is intended for partial or total hip arthroplasty in cementless use. It is a monolithic collarless stem available in 9 sizes (#4-#12) in standard and lateralized versions.

When used in total hip arthroplasty Minima S stems are coupled to:

Biolox Delta femoral heads (object of this submission) or Limacorporate Femoral ● Heads (K112158) articulating with Limacorporate Cemented Cups (K112158) or
Biolox Delta heads (object of this submission) or Limacorporate Femoral Heads (K112158) articulating with Delta TT Acetabular System (K112898).

{4}------------------------------------------------

When used in partial hip arthroplasty the Minima S femoral stem is coupled to Lock Bipolar Heads (Limacorporate K112158).

The Minima S stem is made of Ti6Al4V and it has a plasma sprayed titanium coating in the proximal area (ASTM F1472 - ISO 5832-3). The stem is characterized by a 12/14 conical taper to be coupled to Limacorporate Femoral Heads, Biolox Delta femoral heads or Lock Bipolar Heads. In addition necks are lowered to reduce accidental contact between stem and acetabular cups and they are mirror-polished to reduce abrasion of the UHMWPE cups in case of abnormal contact. The stem has a rectangular section and is characterized by a "V" shaped A-P profile to improve adaptability to the most common bone morphologies and to facilitate insertion of the stem in the canal.

The Minima S System stems is available in standard and lateralized versions with different CCD angles (131° and 134°), offsets and stem lengths.

Biolox Delta Heads devices are used by surgeons to replace the head of the femur during total or partial hip surgery. They are characterized by a spherical shape and are coupled with the acetabular cup (K112158, K112898) inserted in the acetabulum, in total hip replacement, or with Lock Bipolar Heads (K112158) in partial hip replacement.

Biolox Delta heads are coupled with the Minima S stems by means of a 12/14 Morse taper. Biolox Delta heads are made of Biolox Delta ceramic and are available with 28, 32 and 36 mm of diameters and in sizes (offsets) S, M, L and XL (XL size available only for head size 36).

Intended Use:

The Minima S System stems are indicated for use in partial or total hip arthroplasty and are intended for press-fit (uncemented) use. When used in total hip arthroplasty, the Minima S Stems are intended for use with compatible femoral heads and acetabular components. When used in partial hip arthroplasty, the Minima S stems are intended for use with Lock Bipolar Heads.

Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:

· non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia;
· rheumatoid arthritis;
treatment of femoral head and neck fractures;
· revisions in cases of good remaining femoral bone stock.

Predicate Devices:

For the Minima S Stem:

H-MAX S stems (Limacorporate, K112091): ●
Encore Linear Hip (DJO, K972791 and K991325); ●
Modulus Femoral Hip System (Limacorporate, K112158); ●
Taperloc 12/14 Taper Femoral Component (BIOMET, K043537). ●

{5}------------------------------------------------

For the Biolox Delta Heads:

Femoral Heads (Limacorporate, K112158):
Articul/eze (DJO, K883460 and K980513); ●
Biolox Delta Ceramic Femoral Heads (Zimmer, K130899); ●
Biolox Delta Ceramic Femoral Heads (Smith & Nephew, K100412, K083762). ●

Comparable Features to Predicate Device(s):

The Minima S stems are similar to the predicate devices in terms of intended use, indications, design and materials. The Minima S stems can be used in total hip arthroplasty as all predicates and they can be used also in partial hip arthroplasty as the Modulus Femoral Hip System (K112158). All stems are intended for cementless use.

The Minima S stems has a design which is similar to predicates with the exception that Modulus stems are made of 2-pieces coupled through conical taper. Like predicates, the subject device is available in standard and lateralized versions, with different CCD angles, offsets and sizes.

The components of the Minima S stems are manufactured from the same materials as the predicate devices.

The same considerations can be done for the Biolox Delta Heads which are similar for intended use, design and materials to predicates

Non-Clinical Testing:

The Minima S System was tested for fatigue resistance. Mechanical tests were performed on worst case components or constructs. The following tests were performed to demonstrate substancial equivalency of the Minima S System to predicate devices:

Fatigue Test according to ISO 7206-6; ●
Fatigue Tests according to ISO 7206-4 (at the end of the test the pull-out force for ceramic heads has been evaluated).

The tests results demonstrated the device's ability to perform under expected clinical conditions.

In addition the Titanium Plasma Spray coating has been characterized to verify the conformity to FDA guideline and referenced standards.

Biolox Delta heads have been tested for burst strength, fatigue and post-fatigue evaluation in accord to FDA Guidance Document for the Preparation of Premarket Notifications for Ceramic Ball Hip Systems. The tests results demonstrated the device's ability to perform under expected clinical conditions.

{6}------------------------------------------------

Clinical Testing:

Clinical testing was not necessary to demonstrate substantial equivalence of the Minima
S System to the predicate devices.

Regulation Number and Section

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.

(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.
