The TriMed Humeral Supracondylar Fixation system is intended for supracondylar fractures of the distal humerus that occur in the adolescent, adult and elderly population. This system is contraindicated for use in infants and small children because of size discrepancy.

Fractures of the distal humerus that require fixation and lend themselves to open surgical treatment are appropriate indications for use with these devices. This includes simple supracondylar fractures of the distal humerus, isolated medial or lateral column fractures of the distal humerus, T-condylar fractures of the distal humerus, and comminuted intra-articular fractures of the distal humerus are all appropriate indications for fixation with the TriMed Humeral Supracondylar Fixation System.

Selection of specific implants is determined by the physician based on the pattern of fracture. Screw fixation, lateral plating, medial plating, and intramedullary nail plate fixation can be used either alone or in combination depending on the nature of the injury.

The following fracture configurations may be applicable for treatment using the TriMed Humeral Supracondylar Plates and TriMed Humeral Supracondylar Nail Plates:

Fractures of the humerus amenable to nail plate, plate and/or screw fixation where the size, shape, and location of the fractured bone are appropriate for the specific implant(s) being used.
The TriMed Humeral Supracondylar Fixation System intramedullary nail plates and associated screws are intended for use in fixation of fractures of the distal humerus.

Device Description

The TriMed Humeral Supracondylar Fixation System is a set of implants which are to be used as an aid to the treatment of certain types of fractures that lend themselves to the principle of nail plate, plate and/or screw fixation. Devices include Medial Humeral Supracondylar Plates, Posterolateral Supracondylar Plates, Medial Humeral Supracondylar Nail Plates, bone screws, and pins. Like every type of orthopaedic implants, it cannot be assumed to be uniformly effective without risk. Use of these implants is not a substitute for normal tissue healing. These implants are designed to provide additional constraint of movement of a fractured bone and are intended only as an aid to fix the fracture in place during the healing process.

The TriMed Humeral Supracondylar Fixation System consists of implants designed for fixation of certain fractures. Variation in implant size, diameter, and shape are intended to allow the implants to accommodate variations in patient size and sites of application. These devices are manufactured from 316LS medical grade implant quality stainless steel. TriMed Humeral Supracondylar Plates and TriMed Supracondylar Nail Plates should only be used with the appropriate size TriMed Bone Screws and TriMed Supracondylar Nail Plate Interlocking Screws. As with interlocking nail plate and screw fixation in general, the surgeon should take measures to avoid excessive force on implant until bone healing has taken place. This includes protection of the fracture when appropriate, and instructions to the patient to avoid excess loading of the extremity until sufficient healing has taken place.

AI/ML Overview

The document describes the TriMed Humeral Supracondylar Fixation System, a set of implants used for treating certain types of humerus fractures.

Here's an analysis of the provided information regarding acceptance criteria and supporting studies:

A table of acceptance criteria and the reported device performance:

Acceptance Criteria (Bench Testing)	Reported Device Performance (TriMed HSFS)
Transverse Static Failure Load: Device strength should be at least as high as predicate devices.	The means of the failure loads of the plates in the TriMed HSFS far exceed the failure loads of the predicate devices. The lowest failure load of any sample tested of the TriMed HSFS (Medial Humeral Supracondylar Plate) is 85.0 pounds, versus the highest failure load for any sample of either predicate device is 73.3 pounds. This indicates the transverse static strength of the TriMed HSFS is much greater than either of the predicate devices.
Transverse Bend Moment: Device bend moment should be superior to predicate devices.	The transverse bend moment at a 0.75 inch moment arm was far higher in the TriMed HSFS plates than in either of the predicate devices. Specifically, the TriMed Olecranon Hook Plate's bend moment (predicate) was 50.9 inch-pounds, the TriMed Semi Tubular Plate's bend moment (predicate) was 27.8 inch-pounds, while the lowest of the three TriMed HSFS plates, the Medial Humeral Supracondylar Plate, had a bend moment of 70.1 inch-pounds. Thus, the TriMed HSFS plates have a superior bend moment.
Cross Sectional Strength (Computer Analysis): Device's cross-sectional strength should be superior to predicate devices.	A computer analysis showed superiority of the plates in the TriMed HSFS over both of the predicate devices.

Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
For bench testing, the document mentions "any sample tested" and "three of the plates of the TriMed HSFS." While a specific numerical sample size for each material point is not explicitly stated (e.g., how many Medial Humeral Supracondylar Plates were tested for transverse static failure load), it implies that multiple samples of different plate types were tested.

The data provenance is from bench testing conducted by TriMed, Inc. and reviewed by their QA/RA Manager. The sterilization validation was performed by North American Science Associates, Inc. (NAMSA) in their Northwood Ohio testing laboratory. This is laboratory-based data, not patient data.
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. The "ground truth" for this device's performance is based on engineering bench testing results comparing physical strength and mechanical properties against predicate devices and established standards (ASTM-F138/ASTM-F139 for biocompatibility). It does not involve human expert interpretation of medical data.
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. This is not a clinical study involving human judgment. The results are based on objective physical measurements and computer analysis.
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 is a medical device (surgical implant) and the testing described is mechanical bench testing, not a study evaluating human reader performance with or without AI assistance.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a physical implant, not an algorithm or AI product. The "standalone" testing refers to the device itself (implants and plates) under mechanical stress, without human intervention in the test process, but it's not an algorithm.
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
The "ground truth" for the device's performance is established through physical property measurements (transverse static failure load, transverse bend moment) and computational analysis of cross-sectional strength, compared against predicate devices and conforming to material standards (316LS medical grade implant quality stainless steel per ASTM-F138/ASTM-F139). Biocompatibility is based on the material's history of use and a Certificate of Biocompatibility (Attachment J). Sterilization validation was done according to established protocols.
The sample size for the training set:
Not applicable. This is a physical medical device, not a machine learning model, so there is no training set in the typical sense.
How the ground truth for the training set was established:
Not applicable, as there is no training set.

TESTING AND PERFORMANCE DATA

Product Safety testing is not applicable.

Electromagnetic Compatibility and Immunity testing is not applicable.

No other specific guidance document on performance is required for this type of device.

BIOCOMPATIBILITY, STERILIZATION, PACKAGING, AND BENCH TESTING

Biocompatibility - Every implant mentioned above is made from 316LVM biocompatible stainless steel per standards ASTM-F138/ASTM-F139.

This material has a long history of use in implants, including the predicate device and many legally marketed devices within the same classification and same intended use as this device. Further, no supplements or additives are used during the processing of the material and all implants are passivated per ASTM-F86 before and after lasermarking.

A Certificate of Biocompatibility is provided in Attachment J. Therefore, the biocompatibility of the TriMed Humeral Supracondylar Fixation System is based on FDA's clearance of the predicate TriMed device and the well-established history of the use of this material in similar applications.

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

Sterilization - No component of the TriMed Humeral Supracondylar Fixation System is provided sterile.

The sterilization procedure provided in the Recommendations for Sterilization section of the IMPORTANT MEDICAL INFORMATION document (Attachment B) has been validated by the North American Science Associates, Inc. (NAMSA) in their Northwood Ohio testing laboratory for the TriMed Fracture Fixation System (K040112). The test report which reflects testing completed by NAMSA is provided in Attachment G.

This sterilization procedure is applicable to the TriMed Humeral Supracondylar Fixation System because the System did not create a new worst-case sterilization scenario, as discussed in the Sterilization Equivalency Rationale, Attachment I.

Packaging - The complete Humeral Supracondylar Fixation System (implants and tools) is provided in a Sterilization Case. The case includes the company name and logo. Plus the device name: Humeral Supracondylar Fixation System.

Bench Testing - Transverse static and transverse bend moment testing was conducted on the TriMed Olecranon Hook Plate, the TriMed Semi Tubular Plate, and the plates from the TriMed Humeral Supracondylar Fixation system (HSFS), the Medial Humeral Supracondylar Plate, the Posterolateral Humeral Supracondylar Plates, and the Medial Humeral Supracondylar Nail Plate. This testing was conducted to verify that the strength of the TriMed HSFS is at least as high as the predicate devices.

As shown in the comparison table in the Substation Equivalence Discussion section, the transverse static failure load, the means of the failure loads of the plates in the TriMed HSFS far exceed the failure loads of the predicate devices. Further, the lowest failure load of any sample tested of the TriMed HSFS (the Medial Humeral Supracondylar Plate) is 85.0 pounds, versus the highest failure load for any sample of either predicate device is 73.3 pounds. This indicates that the transverse static strength of the TriMed HSFS is much greater than either of the predicate devices.

As shown in the comparison table in the Substation Equivalence Discussion section, the transverse bend moment at a .75 inch moment arm was far higher in the TriMed HSFS plates than in either of the predicate devices. Specifically, the TriMed Olecranon Hook Plate's bend moment was 50.9 inch-pounds, the TriMed Semi Tubular Plate's bend moment was 27.8 inchpounds while the lowest of the three TriMed HSFS plates, the Medial Humeral Supracondylar Plate, had a bend moment of 70.1 inch pounds. Thus, the TriMed HSFS plates have a superior bend moment to either of the predicate devices.

Finally a computer analysis was conducted on both predicate devices and all three of the plates of the TriMed HSFS, as shown in the comparison table. This analysis of cross sectional strength showed superiority of the plates in the TriMed HSFS over both of the predicate devices.

See Attachment H for the Test Report.

CONCLUSION

It is therefore the conclusion of TriMed that the Humeral Supracondylar Fixation System is substantially equivalent to devices already on the market [cleared by the 510(k) process] and presents no new concerns about safety and effectiveness.

Regulation Number and Section

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
