The Biomet Headless Compression Screws and Twist-Off Screws are indicated for fixation of bone fractures, fusion of a joint (arthrodesis) or bone reconstruction (osteotomy) of the mid-foot bones, metatarsal and phalanges of the foot or the phalanges, metacarpals and carpals of the hand. In the foot, these include procedures to correct Hallux Valgus (bunions), Hallux Varus and Hallux Rigidus, Hammer toe, Claw toe and Mallet toe.
The WasherLoc™ and No-Profile Screw and Washer Systems are internal soft tissue fixation devices that aid in arthroscopic and orthopedic reconstructive procedures. The system includes instrumentation allowing for proper preparation and placement of the soft tissue fixation device.
The No-Profile Screw and Washer System includes titanium alloy (Ti-6A1-4V) screws and washers in various lengths/sizes. Both 4.5mm and 6.0mm diameter screws in lengths from 24mm to 70mm are available. The No-Profile Washers are available in 14mm, 16mm, and 18mm diameters with and without spikes. The spikes on the washers are not intended for additional fixation as used with the No-Profile screws.
The WasherLoc™ Tibial Fixation System includes titanium alloy (Ti-6Al-4V) screws and washers in various lengths and sizes. Both 4.5mm and 6.0mm diameter screws in lengths from 24mm to 60mm are available. The WasherLoc™ Washers are available in 14mm, 16mm, and 18mm diameters with spikes intended for additional fixation.
The Biomet Cannulated Screw System is designed for a variety of internal fixation, aiding in the alignment, stabilization, and healing of fractures or osteotomies to the skeletal system. The Biomet Cannulated Screw System has multiple variants included which fluctuate in screw diameters and lengths, and include the associated essential instruments that aid in fracture fixation.
The Biomet Cannulated Screw System consists of screw variants, which are available in diameters of 3.0mm, 4.0mm, 5.0mm, 6.5mm, and 8.0mm. Each screw diameter is accompanied by instruments that are designed specifically for a given diameter. Washers are also part of the Biomet Cannulated Screw System and are sized 3.0mm, 4.0mm, 5.0mm, 6.5mm, and 8.0mm to specifically match each screw diameter. The washers are provided to add additional support under the head of the screw in situations where the bone quality is poor. Washers are also utilized for more surface area contact with the bone which needed in order to maintain proper fixation of the fracture or osteotomy.
The Biomet Headless Compression and Twist-Off Screws are used for fixation of bone fractures, fusion of a joint, or bone reconstruction, osteotomies of the mid-foot bones, metatarsals and phalanges of the foot and metacarpals, phalanges and carpals of the hand. The Ti-6Al-4V alloy Biomet Headless Compression and Twist-Off Screws have multiple lengths and diameters associated with the different screws ranging from 2.0 to 3.0mm in diameter and lengths from 8 to 40mm. Both sets of screws will be available in sterile and non-sterile configurations. The screws include the associated essential instruments that aid in fracture fixation.
The Biomet Headless Compression Screw is a cannulated headless screw which is inserted below the bone surface. This feature helps to minimize soft tissue irritation by sitting recessed and provides compression due to a dual thread design in the shaft and head.
The Biomet Twist-Off Screw is a solid one-piece screw that has a drive shaft that has the ability to connect to a drill or large diameter pin driver. In addition, the screw incorporates a breakaway zone between the head and direct connection that allows the screw to break-off cleanly upon insertion. The Biomet Twist-Off Screw also has compression capabilities with a thread-free segment that achieves compression at the osteotomy site.
This document describes the FDA's decision regarding the 510(k) premarket notification for several orthopedic screw systems (WasherLoc™ and No-Profile Screw and Washer Systems, Biomet Cannulated Screw System, and Biomet Headless Compression and Twist-Off Screws). The core of this submission is not about a novel AI/ML device or a device that performs diagnostic or prognostic functions based on data analysis. Instead, it's about a change in the manufacturing process (bioburden reduction) for existing, already cleared devices.
Therefore, the requested information categories related to acceptance criteria for AI performance, clinical studies, sample sizes for test/training sets, expert ground truth, adjudication methods, and MRMC studies are not applicable to this document. This submission focuses on demonstrating that a manufacturing process change does not alter the safety or effectiveness of physical medical devices.
However, I can extract the relevant information regarding the rationale for substantial equivalence:
1. A table of acceptance criteria and the reported device performance:
Since this is a submission for a manufacturing process change for physical medical devices, acceptance criteria are generally related to the physical and biological properties of the devices after the new process, and the ability to maintain the same performance as the predicate devices. The document explicitly states:
Acceptance Criteria Category | Reported Device Performance |
---|---|
Intended Use | Same as predicate devices |
Indications for Use | Similar to predicate devices |
Materials | Same as predicate devices |
Design Features | Similar to predicate devices |
Sterilization Method | Same as predicate devices (after the change to REVOX technology is validated) |
Non-Clinical Tests | Assessed effects of REVOX process on Ti devices (process residuals, analytical tests like ICP-MS for metallic/nonvolatile residues); Bioburden reduction process impact on shelf life; Sterilization validation (dosage, SAL); Bacterial Endotoxin Test (non-pyrogenicity). |
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):
- Not Applicable. This submission is not a clinical study to assess diagnostic or prognostic performance of an AI model. The "tests" mentioned are non-clinical, laboratory-based tests on the physical devices.
- The document implies that the tests performed (e.g., cytotoxicity, analytical testing, bioburden reduction, sterilization validation, BET) were conducted on the subject devices that underwent the new REVOX bioburden reduction process. No specific sample sizes for these in-vitro/bench tests are reported in this summary.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):
- Not Applicable. No ground truth in the context of expert review of data is established for this type of submission. The "ground truth" for non-clinical tests would be defined by validated laboratory standards and methodologies.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not Applicable. No adjudication method for medical image interpretation or similar data is mentioned as this is a device modification submission, not a diagnostic AI clearance.
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. No MRMC study was performed as this is not an AI/ML diagnostic or assistive device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This is not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Not Applicable. For the non-clinical tests conducted, the "ground truth" is defined by established scientific and engineering principles, material science standards, and biological safety testing protocols (e.g., sterility assurance level (SAL), pyrogenicity limits, material composition standards).
8. The sample size for the training set:
- Not Applicable. No training set exists as this is not an AI/ML device.
9. How the ground truth for the training set was established:
- Not Applicable. No training set or associated ground truth.
In summary, this FDA clearance is for a change in the manufacturing process (bioburden reduction) of existing orthopedic screws, not for a new AI/ML medical device. Therefore, most of the requested information regarding AI performance criteria and studies is not relevant to this document. The "study" referenced is a series of non-clinical, laboratory-based tests to ensure the REVOX process does not negatively impact the safety and performance characteristics of the devices compared to their previously cleared versions.

3.Omm Biomet Cannulated Screw System
- Fixation of small bones, including those in the foot, patella, ankle, wrist and elbow.
- Arthrodesis of the foot, wrist and elbow.
- Small and long bone osteotomies.
- Fracture fixation of small bones, small bone fragments and long bones.
The 3.0mm Biomet Cannulated Screw System consists of bone screws of various lengths and are Ti alloy partially threaded screws with the associated 3.0mm washer. They are offered in both a sterile and non-sterile configuration. The 3.0mm Biomet Cannulated Screw System also contains dimensionally optimized corresponding instruments which are used with the 3.0mm Biomet Cannulated Screws and washers to aid in the alignment and stabilization of fractures to the skeletal system.
This document is a 510(k) premarket notification for a medical device called the "3.0mm Biomet Cannulated Screw System." It seeks to demonstrate substantial equivalence to legally marketed predicate devices, not necessarily to prove specific performance criteria against predefined thresholds.
Therefore, the requested information elements related to acceptance criteria and a study proving those criteria are not directly applicable or available in this specific type of regulatory submission document. This document focuses on demonstrating that the new device is as safe and effective as a previously cleared device.
However, I can extract the relevant information from the document as it pertains to the basis for substantial equivalence, which includes some performance data.
Here's a breakdown based on your request, as much as can be derived from the provided text:
1. A table of acceptance criteria and the reported device performance
This document does not specify formal "acceptance criteria" for clinical performance that would typically be seen in a clinical trial. Instead, the performance is compared against predicate devices to demonstrate substantial equivalence. The non-clinical tests indicate that the new device's performance is "equal to or better than the predicate devices."
Acceptance Criteria Category | Acceptance Criteria (Implicit from Equivalence) | Reported Device Performance |
---|---|---|
Torsional Strength | Comparable to or better than predicate devices (e.g., FRS screw K062352, DartFire screw K082320). | Equal to or better torsional yield strength than predicate screws. |
Axial Pullout Strength | Comparable to or better than predicate devices. | Equal to or better than predicate devices. |
Insertion/Removal Torque | Comparable to or better than predicate devices. | Equal to or better than predicate devices. |
Material | Same material (Ti-6Al-4V alloy per ASTM F136) as K140891, and similar to K082874 and K962823 predicate devices. | Identical to K140891, similar to K082874 and K962823. |
Design Features | Similar in design and dimension to K140891 (line extension), and similar to K082874 and K962823 predicate devices. | Similar to K140891, K082874, and K962823. |
Sterilization | Identical to K140891, and similar to K082874 and K962823 predicate devices. | Identical to K140891, similar to K082874 and K962823. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not specified. The non-clinical tests were conducted per ASTM F543, which specifies testing methodologies, but the sample size used for these specific tests is not provided in this summary.
- Data Provenance: Not specified, but generally, bench testing (non-clinical) occurs in a lab setting, not tied to patient data. Since no clinical studies were performed, there is no patient data provenance to report.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not applicable. This device underwent non-clinical (bench) testing, not clinical studies requiring expert ground truth establishment.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. This was bench testing, not a clinical study involving human judgment or adjudication.
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
- No. This is a bone fixation screw system, not an AI/imaging device. Therefore, no MRMC study or AI assistance evaluation was performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This is a physical medical device (bone screw), not an algorithm or software.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- For the non-clinical tests, the "ground truth" or reference for performance was established by standardized mechanical testing methodologies (ASTM F543) and comparison to the performance of legally marketed predicate devices. There is no clinical ground truth (like pathology or outcomes data) mentioned because no clinical studies were performed.
8. The sample size for the training set
- Not applicable. This is a physical medical device, not a machine learning algorithm that requires a training set.
9. How the ground truth for the training set was established
- Not applicable. As above, this is not a machine learning algorithm.

The Biomet Cannulated Screw System consists of bone screws, associated washers, which are manufactured from Titanium-6 Aluminum-4 Vanadium (Ti-6AL-4V), and corresponding instruments are used to aid in the alignment and stabilization of fractures to the skeletal system.
Here's an analysis of the provided text regarding the Biomet Cannulated Screw System's acceptance criteria and study proving its efficacy:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Defined by Predicate Devices) | Reported Device Performance (Summary of Non-Clinical Tests) |
---|---|
Design similar to predicate devices | Similar design to predicate devices. |
Dimensions similar to predicate devices | Similar dimensions to predicate devices. |
Material identical/similar to predicate devices | Fabricated from Ti-6Al-4V alloy per ASTM F136 (a commonly used material in orthopedic implants and used in predicate devices K082874, K903810, K926047, K872859). |
Meets mechanical standards (ASTM F543) | Performed torsional, axial pullout, and driving torque mechanical tests per ASTM F543. Results indicate substantial equivalence to legally marketed devices. |
Safe and effective performance | No new issues of safety or efficacy have been raised. Results indicate the device will perform within the intended use. |
MRI compatibility/justification | MRI justification performed. |
Cadaver evaluation | Cadaver evaluation performed. |
2. Sample Size Used for the Test Set and Data Provenance
The provided document does not specify a sample size for a test set. The evidence for substantial equivalence is based on non-clinical performance testing (mechanical tests, cadaver evaluation, MRI justification) and comparison to predicate devices, rather than a clinical "test set" in the context of human data.
The data provenance is non-clinical (laboratory and cadaveric testing).
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications
This information is not applicable as there was no clinical "test set" in the traditional sense that required expert interpretation for ground truth. The evaluation focused on material properties, mechanical performance, and design equivalence to established predicate devices.
4. Adjudication Method for the Test Set
This is not applicable as there was no clinical "test set" requiring adjudication or multi-reader reviews.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The document explicitly states: "Summary of Clinical Tests Conducted for Determination of Substantial Equivalence and/or of Clinical Information: None provided as a basis for substantial equivalence." This indicates that no clinical studies, including MRMC studies, were performed to compare the performance of human readers with and without AI assistance for this device.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
This is not applicable. The device is a physical medical implant (a cannulated screw system), not an AI algorithm. Therefore, a standalone performance study for an algorithm is not relevant.
7. The Type of Ground Truth Used
The "ground truth" for the device's performance was established through:
- Engineering specifications and standards: Adherence to ASTM F136 (material) and ASTM F543 (mechanical testing).
- Performance of predicate devices: The Biomet Cannulated Screw System's characteristics (design, dimensions, material) and performance were compared to those of legally marketed predicate devices, which implicitly serve as the "ground truth" for acceptable safety and effectiveness.
- Non-clinical testing results: Specifically, the outcomes of torsional, axial pullout, and driving torque mechanical tests, and MRI justification, demonstrated "substantial equivalence."
8. The Sample Size for the Training Set
This is not applicable. As a physical medical device (cannulated screw system), there is no 'training set' in the context of machine learning or AI.
9. How the Ground Truth for the Training Set Was Established
This is not applicable for the reasons stated above (not an AI/ML device).
