The description focuses solely on the mechanical components and materials of a pedicle screw system, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes.
Explanation: The device is a spinal implant intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion for treating various spinal conditions.
No
This device, the KRD1™ Pedicle Screw System, is a mechanical implant used for immobilization and stabilization of spinal segments, not for diagnosing conditions.
No
The device description clearly outlines physical components made of titanium alloy (screws, rods, connectors, instrumentation) and discusses mechanical testing, indicating it is a hardware-based medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the KRD1™ Pedicle Screw System is for "immobilization and stabilization of spinal segments... as an adjunct to fusion." This describes a surgical implant used directly within the body to treat structural issues.
- Device Description: The description details components like screws, rods, and connectors, all of which are physical implants designed for surgical placement.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is used in vivo (inside the body) as a surgical implant.

Intended Use / Indications for Use
The KRD1™ Pedicle Screw System is 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 instabilities or deformities of the thoracic, lumbar, and sacral spine: degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (Pseudoarthrosis).
In addition, the KRD1™ Pedicle Screw System is indicated for the treatment of severe spondylolisthesis (Grade 3 and 4) of the L5-S1 vertebra in skeletally mature patients receiving fusion by autogenous bone graft.

Device Description
The KRD1™ Pedicle Screw System consists of longitudinal rods, polyaxial screws, transverse connectors, and instrumentation to facilitate installation of this system.
The KRD1™ Pedicle Screw is offered in multiple screw diameters, with multiple lengths to accommodate individual patient needs. KRD1™ Pedicle Screw assemblies consist of the screw, a tulip, and a washer that secures the tulip to the screw and also serves as the saddle for the longitudinal rod. The tulip and screw designs allow the screw to have a polyaxial rotation relative to the tulip. A locking cap is placed on top of the pedicle screw assembly to secure the position of the implant and to retain the longitudinal rod.
The KRD1™ Pedicle Screw assembly serves as the central fixation device to which various rods and cross connectors are secured to provide desired fixation.
Longitudinal rods are provided in two configurations, straight and lordotic, have a fixed diameter (5.5mm), and vary by length.
Cross connector assemblies are provided in multiple configurations, varying by length. Cross connectors are used to provide additional fixation support.
The KRD1™ Pedicle Screw System components are fabricated from medical grade titanium alloy conforming to ASTM F-136 specifications.

§ 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.
