UNiD™ Patient Specific Rods are differentiated in two subgroups: UNiD™ Patient Specific Standard Rods (UNiD ROD) and UNiD™ Patient Specific Percutaneous Rods (UNiD™ Patient Specific Rods have been designed and manufactured for one specific patient. UNiD™ Patient Specific Rods must be used during surgery for this patient only and must not be reused (single use only). The UNiD™ Patient Specific Rods 4.75 diameter rods are not compatible with the PASS LP system. For a complete guide to the system, it is important to refer to the surgical technique.
Please find the information regarding the acceptance criteria and study for the device below.
The provided text is a 510(k) Summary for the CD Horizon™ Spinal System and PASS LP™ Spinal System, which are pedicle screw fixation systems. This document focuses on demonstrating substantial equivalence to previously cleared predicate devices, particularly for UNiD™ Patient Specific Rods. The primary purpose of this submission is to add UNiD™ Patient Specific Rods (new diameter 4.75mm) and to change the proprietary Trade Name from "PASS LP™ Patient Specific Rods" to "UNiD™ Patient Specific Rods."
The testing conducted is for mechanical equivalence, not clinical performance or diagnostic accuracy. Therefore, concepts like sensitivity, specificity, accuracy, and reader studies (MRMC, standalone algorithm performance) are not applicable to this type of device submission. The acceptance criteria and "performance" here refer to mechanical strength and durability.
Here's a breakdown of the information requested:
1. Table of Acceptance Criteria and Reported Device Performance
Given the nature of the device (implantable spinal system), the acceptance criteria are based on mechanical properties as per a recognized standard. The document does not provide specific numerical acceptance criteria (e.g., minimum load values) but rather states that testing was conducted in accordance with a standard and demonstrated mechanical equivalence.
| Acceptance Criteria (Mechanics) | Reported Device Performance (Mechanics) |
|---|---|
| Conformity to ASTM F1717-18 for: | Testing confirmed that the subject devices are substantially equivalent to the predicates. |
| - Static Compression Bending | |
| - Dynamic Compression Bending | |
| - Static Torsion | |
| Mechanical equivalence to predicate devices (K113174 and K140738) | Mechanical equivalence of the subject UNiD™ Patient Specific Rods when used with the CD Horizon™ Spinal System was demonstrated. |
2. Sample Size for the Test Set and Data Provenance
- Sample Size for Test Set: Not explicitly stated. Mechanical testing typically involves a sufficient number of samples (e.g., typically n=5 or n=6 per test condition for medical device mechanical testing) to provide statistically significant results according to the chosen standard (ASTM F1717-18).
- Data Provenance: The testing was conducted by Medicrea (Medtronic). It's scientific/engineering test data, not patient data, so 'country of origin' of data or 'retrospective/prospective' doesn't apply in the common clinical sense. The manufacturer is based in France.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Number of Experts: Not applicable. Ground truth for mechanical testing is established by recognized engineering standards (ASTM F1717-18) and measured physical properties, not expert consensus.
- Qualifications of Experts: N/A.
4. Adjudication Method for the Test Set
- Adjudication Method: Not applicable. This is mechanical testing data, not human-interpreted data. Results are quantified using laboratory equipment.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- MRMC Study Done: No. This type of study is for evaluating the impact of a diagnostic or assistive AI device on human reader performance. This submission is for an implantable medical device, not a diagnostic or AI-driven system.
6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study
- Standalone Study Done: No. This also refers to AI algorithm performance, which is not relevant to this mechanical device submission.
7. Type of Ground Truth Used
- Type of Ground Truth: Engineering standards and measurements of mechanical properties. The "ground truth" is adherence to established, validated mechanical test methods (ASTM F1717-18) that ensure the device is "substantially equivalent" in performance to predicate devices.
8. Sample Size for the Training Set
- Sample Size for Training Set: Not applicable. This concept applies to machine learning models. The manufacturing process of UNiD™ Patient Specific Rods involves patient-specific design (i.e., custom bending for one specific patient based on their anatomy), but this is not an AI "training set."
9. How the Ground Truth for the Training Set Was Established
- How Ground Truth for Training Set Was Established: Not applicable. No "training set" in the machine learning sense is used here. For the patient-specific rods, the "ground truth" for each rod's design is the specific patient's anatomical requirements, which are determined via medical imaging and planning, not a training set.

| VI. | Comparison of Technological Characteristics with the Predicate Devices |
{7}------------------------------------------------
{8}------------------------------------------------
When the subject device UNiD™ Patient Specific Rods (including new diameter 4.75mm) is used with the CD Horizon Spinal System, they have the same fundamental scientific technology, indications for use, intended use, materials, and levels of attachment as the predicate CD Horizon™ Spinal System devices (K113174).
The compatibility between the whole CD Horizon™ Spinal System and PASS LP™ Patient Specific Rods (Diameter 5.5mm and 6.0mm) is already cleared (K202771, Cleared. 10/19/2020).
{9}------------------------------------------------
The difference between the predicate device CD Horizon™ rods (K113174, cleared 11/21/2011) and subject device is that rods used with the predicate CD Horizon™ Spinal System are cut and bent by the surgeon based on the need of the individual case, while the UNiD™ Patient Specific Rods are directly adapted to a unique patient by means of an industrial bending process prior to distribution for surgery. However, both the subject and predicate systems are intended to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the thoracic, lumbar, or sacral spine.
In addition, the subject device UNiD™ Patient Specific Rods is directly adapted to a unique patient as the predicate device previously cleared PASS LP™ Spinal System (K140738, Cleared 11/04/2014).
VII. Performance Data (Non-Clinical Test Summary)
In accordance with the Guidance for Industry and FDA Staff – Spinal System 510(k)'s, Medicrea has evaluated the subject devices to demonstrate substantial equivalence to the predicate devices. Static and dynamic compression bending and static torsion testing were conducted in accordance with ASTM F1717-18. This performance testing demonstrates mechanical equivalence of the subject UNiD™ Patient Specific Rods when used with the CD Horizon™ Spinal System.
Therefore, Medicrea believes that the testing confirmed that the subject devices are substantially equivalent to the predicates.
VIII. Conclusion
The UNiD™ Patient Specific Rods (including new Diameter 4.75mm) have shown through supporting information provided in this premarket notification to be substantially equivalent to the identified predicates.
§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:
“Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.”
“Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.”
(2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls:
(i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant.
(iii) Device components must be demonstrated to be biocompatible.
(iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(v) Labeling must include the following:
(A) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(B) Intended use and indications for use, including levels of fixation;
(C) Identification of magnetic resonance (MR) compatibility status;
(D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and
(E) Detailed instructions of each surgical step, including device removal.
(3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls:
(i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate.
(ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.
