Intended Use

The RASL Repair Kit is intended to provide fixation and anatomically reduce two bones or bone portions. Specifically, these indications include acute or chronic, static or dynamic scapholunate instability in the absence of significant capitolunate osteoarthritis, scapholunate ligament repair, scapholunate reduction, lunotriquetral ligament repair, lunotriquetral reduction, and carpal instability.

Device Description

The Radicle Orthopaedics RASL Repair Kit is an implant and instrument system designed to treat scapholunate ligament ("SLIL") ruptures. The RASL Repair Kit implants are made from titanium alloy, Ti-6Al-EV ELI, per ASTM F136. Instruments are made from surgical-grade stainless steel according to ASTM F899. The entire kit is supplied non-sterile. Instruments are meant to be reusable.

AI/ML Overview

The provided document is a 510(k) Premarket Notification from the U.S. Food and Drug Administration (FDA) for the Radicle Orthopaedics RASL Repair Kit. It primarily focuses on demonstrating substantial equivalence to predicate devices based on indications for use, design, material, and performance testing.

This document describes a medical device (a bone fixation fastener) and its performance through physical (mechanical) testing, not an AI/ML-based device that would require the type of studies and criteria (e.g., accuracy, sensitivity, specificity, human reader improvement, ground truth establishment) typically associated with AI/ML evaluation.

Therefore, I cannot extract information to fill out the requested template as it pertains to AI/ML device performance. The information requested, such as 'acceptance criteria based on computational metrics,' 'sample sizes for test and training sets using patient data,' 'number of experts for ground truth,' and 'MRMC studies,' are not applicable to the mechanical testing described in this document.

The document discusses the following types of performance data (mechanical testing):

  • Torsional Testing per ASTM F543
  • Insertion/Removal and Axial Pullout Testing per ASTM F543
  • Assembly Strength Testing
  • Static and Fatigue Bending Testing per ASTM F1264
  • Corrosion Testing per ASTM F2129
  • Wear Debris Testing per ASTM F1877

These tests compare the physical properties and strength of the RASL Repair Kit to its predicate devices (Acumed SLIC Screw Repair System and Zimmer HBS Screw System) to demonstrate substantial equivalence, rather than clinical performance based on patient data and AI algorithms.

Description of the Device

The Radicle Orthopaedics RASL Repair Kit is an implant and instrument system designed to treat scapholunate ligament ("SLIL") ruptures. The RASL Repair Kit implants are made from titanium alloy, Ti-6Al-EV ELI, per ASTM F136. Instruments are made from surgical-grade stainless steel according to ASTM F899. The entire kit is supplied non-sterile. Instruments are meant to be reusable.

{4}------------------------------------------------

Indications for Use

The RASL Repair Kit is intended to provide fixation and anatomically reduce two bones or bone portions. Specifically, these indications include acute or chronic, static or dynamic scapholunate instability in the absence of significant capitolunate osteoarthritis, scapholunate ligament repair, scapholunate reduction, lunotriquetral ligament repair, lunotriquetral reduction, and carpal instability.

Summary of Technical Similarities and Differences

The Radicle Orthopaedics RASL Repair Kit is substantially equivalent to the Acumed SLIC Screw Repair System (K111608) and the Zimmer HBS Screw System (K143165). The devices have the similar "Indications for Use" and product codes, are available by prescription only, have similar sizes offered and are provided non-sterile.

The devices also all include a larger proximal threaded portion and a smaller distal threaded portion.

The RASL device and the HBS device are both made from titanium alloy while the SLIC screw is made from stainless steel.

The key technical difference between the implants is the allowance for angulation and rotation of the distal and proximal portions of the respective implants. The SLIC screw allows for 15 to 22 degrees of toggle angle and freely rotates while the HBS screw is monolithic in nature, allowing for neither rotation or angulation. The RASL screw allows for free rotation while limiting angulation.

Summary of Performance Data

To characterize the strength of the RASL Repair Kit implants and compare to the predicates, the following testing was performed:

  • Torsional Testing per ASTM F543
  • Insertion/Removal and Axial Pullout Testing per ASTM F543
  • Assembly Strength Testing
  • Static and Fatigue Bending Testing per ASTM F1264
  • Corrosion Testing per ASTM F2129
  • Wear Debris Testing per ASTM F1877

Safety & Effectiveness

The Radicle Orthopaedics RASL Repair Kit is substantially equivalent to the predicate devices. The devices have the same Indications for Use, are available by prescription only, have similar sizes offered and are provided non-sterile. In addition, the RASL system performed substantially equivalently to the predicate devices in all testing modes.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
