Intended Use

The VADER® Pedicle System is intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the thoracic and lumbar spine in whom life expectancy, prior to oncological treatment, is of insufficient duration to permit achievement of fusion.

When used in conjunction with G21 V-Fast or V-Steady Bone Cement and PicoMix™ V and/or V-HP Gun with the icotec Cement Cannula for mixing and injection of bone cements, the fenestrated VADER® pedicle screws are intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the thoracic and lumbar spine in whom life expectancy, prior to oncological treatment, is of insufficient duration to permit achievement of fusion. The fenestrated VADER® pedicle screws augmented with G21 V-Fast or V-Steady Bone Cement are for use at spinal levels where the structural integrity of the spine is not severely compromised.

The VADER® Pedicle System is indicated to provide the surgeon with a minimally invasive and open approach for posterior spinal surgery.

When used in conjunction with the icotec VADER® Pedicle System, G21 V-Fast and V-Steady Bone Cement are intended to restore the integrity of the spinal column even in the absence of fusion for a limited time in patients with advanced stage tumors involving thoracic and lumbar spine in whom life expectancy, prior to oncological treatment, is of insufficient duration to permit achievement of fusion.

Device Description

The VADER® Pedicle System is a posterior pedicle system manufactured from Carbon/PEEK using a proprietary manufacturing process and comprised of polyaxial pedicle screws and curved, straight, S-rods and J-rods as well as polyaxial, cannulated, fenestrated pedicle screws. The VADER® Pedicle System can be used for single or multiple level fixations in the non-cervical spine.

AI/ML Overview

The provided text does not contain information about the acceptance criteria or a study proving that the device meets specific performance criteria in the context of an AI/ML device. The document is an FDA 510(k) clearance letter for a medical device, specifically the VADER® Pedicle System and G21 Cement, which are physical implants and bone cement, not an AI/ML diagnostic or therapeutic device.

Therefore, I cannot extract the following information from the provided text:

  1. A table of acceptance criteria and the reported device performance
  2. Sample size used for the test set and the data provenance
  3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
  4. Adjudication method for the test set
  5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size
  6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
  7. The type of ground truth used
  8. The sample size for the training set
  9. How the ground truth for the training set was established

The "Performance Testing Summary" section (Page 6) briefly mentions mechanical testing performed per ASTM standards (F1717, F1798, F543/F2193) and cement injection testing for the VADER® Pedicle System and G21 Cement. These are engineering performance tests for a physical device, confirming its structural integrity and functional characteristics, not clinical performance metrics for an AI/ML algorithm. The conclusion states that the device is "substantially equivalent" to predicate devices based on these mechanical tests.

§ 888.3027 Polymethylmethacrylate (PMMA) bone cement.

(a)
Identification. Polymethylmethacrylate (PMMA) bone cement is a device intended to be implanted that is made from methylmethacrylate, polymethylmethacrylate, esters of methacrylic acid, or copolymers containing polymethylmethacrylate and polystyrene. The device is intended for use in arthroplastic procedures of the hip, knee, and other joints for the fixation of polymer or metallic prosthetic implants to living bone.(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Polymethylmethacrylate (PMMA) Bone Cement.”
