Intended Use
The LEUCADIA™ 4.5 mm Pedicle Screw System is intended to be used as an adjunct to fusion using autograft or allograft in posterior, non-cervical fixation for the following conditions: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e. fracture or dislocation); spinal stenosis; curvatures (i.e. scoliosis, kyphosis and/or lordosis); tumors; pseudarthrosis; and/or failed previous fusion.
Device Description
The Leucadia™ 4.5 mm Pedicle Screw System is intended to help provide correction, immobilization and stabilization of spinal segments as an adjunct to fusion of the thoracic, lumbar and/or sacral space. The Leucadia™ 4.5 mm Pedicle Screw System consists of 4.5 mm diameter screws, which are available in 7 different lengths: 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, and 55 mm. All sizes are able to receive 5.5mm connecting rods only. The Leucadia™ 4.5 mm Pedicle Screw System implant components are fabricated from medical grade titanium alloy (Ti-6Al-4V ELI) conforming to ASTM F136 or equivalent. The Leucadia™ 4.5 mm Pedicle Screw System is a temporary implant system intended to be removed after solid fusion has occurred. Leucadia™ 4.5 mm Pedicle Screw System implant components are an addition to the existing Leucadia™ Pedicle Screw System (K110588 - S/E May 25, 2011). It should not be used with components from any other manufacturer. As with all orthopedic implants, Leucadia™ 4.5 mm Pedicle Screw System components should not be reused.
More Information

Not Found

No
The description focuses on the mechanical components and materials of a pedicle screw system, with no mention of software, algorithms, or AI/ML capabilities.

Yes
The device is intended to provide correction, immobilization, and stabilization of spinal segments as an adjunct to fusion for various medical conditions, indicating a therapeutic purpose.

No

The device is a pedicle screw system used for surgical fixation, not for diagnosing medical conditions.

No

The device description explicitly states it consists of physical components (screws, rods) made of titanium alloy, indicating it is a hardware 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 describes a surgical implant system used to stabilize the spine during fusion. This is a therapeutic device, not a diagnostic one.
  • Device Description: The description details physical components (screws, rods) made of titanium alloy, designed for implantation in the body. This is characteristic of a medical device used for treatment.
  • Lack of Diagnostic Elements: There is no mention of analyzing samples from the human body (like blood, urine, tissue), which is the core function of an IVD.
  • Anatomical Site: The device is used in the body (thoracic, lumbar, sacral space), not for testing samples from the body.

In summary, the LEUCADIA™ 4.5 mm Pedicle Screw System is a surgical implant intended for spinal stabilization, which falls under the category of a medical device, not an In Vitro Diagnostic.

§ 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.
