Intended Use

The Stabilizer Soft Tissue Anchor is intended for use with USP Sutures as an attachment means for soft tissue and bone for the indications listed below: Shoulder (Bankart repair, SLAP lesion repair, Acromioclavicular separation, Rotator cuff repair, Capsule shift \capsulolabral reconstruction, Biceps tenodesis, Deltoid repair), Elbow (Tennis elbow repair, Biceps tendon reattachment, Medial and lateral repairs), Ankle (Lateral instability, Medial instability, Achilles tendon repair/ reconstruction), Knee (Extra-capsular repairs and attachment of: medial collateral ligament, lateral collateral ligament, posterior oblique ligament and joint capsule to tibia, joint capsule closure to the anterior proximal tibia; Extra-capsular reconstruction, ITB tenodesis; Patellar ligament and tendon avulsions repairs)

Device Description

The Stabilizer Soft Tissue Anchor is a 316L Stainless Steel implant designed to provide an attachment means for soft tissue to bone using USP grade surgical sutures in joint reconstruction procedures. It is available in two sizes: 5 and 8 mm diameter. Attachment is accomplished by drilling an appropriately sized hole in uncompromised bone with a specifically designed drill, inserting the soft tissue anchor into the bone, expanding the stabilizer teeth of the implant to secure the anchor into bone using the anchor inserter, and securing soft tissue to the implanted anchor by using three sutures. The anchor inserter (which spreads the stabilizer teeth of the implant) also serves as a suture organizer for delivery of sutures to the implant site during the implantation procedure. A crimper is also included to help secure the suture of choice to the Stabilizer and to prepare the stabilizer for entry into the predrilled hole.

AI/ML Overview

This document is a 510(k) premarket notification for a medical device, the Stabilizer™ Soft Tissue Anchor. It describes the device, its indications for use, contraindications, and comparisons to a predicate device.

Unfortunately, this document does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria.

Specifically, the document does not include:

  • A table of acceptance criteria and reported device performance.
  • Details about any studies (clinical or non-clinical) that demonstrate the device's performance.
  • Sample sizes used for test sets or data provenance.
  • Information on experts used for ground truth establishment or adjudication methods.
  • Information about multi-reader multi-case (MRMC) comparative effectiveness studies.
  • Information about standalone algorithm performance.
  • The type of ground truth used.
  • Sample size for training sets.
  • How ground truth for training sets was established.

This 510(k) summary is a regulatory submission focused on demonstrating substantial equivalence to a predicate device, not on detailing a rigorous performance study with specific acceptance criteria and results. For a device like this (a mechanical anchor), performance data would typically involve biomechanical testing (e.g., pull-out strength, fatigue testing) rather than clinical studies with "ground truth" in the way an AI diagnostic device would. However, even for biomechanical testing, specific acceptance criteria and results would be presented.

CONTRAINDICATIONS, WARNINGS, PRECAUTIONS AND COMPLI-CATIONS

    1. Contraindications
      The Stabilizer Soft Tissue Anchor is contraindicated in the presence of pathological conditions such as severe osteopenia, cystic degeneration, or comminution of bone which would compromise fixation. the Stabilizer should not be used in compromised bone or in the presence of pathological soft tissue conditions which would compromise fixation. It should also not be used in the presence of pathophysiological conditions such as infection, osteonecrosis, or bone disease. The product should not be used in patients with known allergies to stainless steel.
    1. Warnings
    • The Stabilizer Soft Tissue Anchor is intended to assist in the 2.1 fixation of soft tissue to bone. Each case should be carefully analyzed to assure that the appropriate sized anchor and suture are being used and that the appropriate number of anchors are present to support the reconstruction. Excessive tension on the suture or anchor may result in suture breakage or implant pullout from the bone. In some cases, revisions may require explant of the bone anchor."
    • To assure proper bone cutting 2.2 The drill is stainless steel. characteristics, the drill should be replaced after every 10 uses. If the drill should break during use, remnants should be removed from the surgical site prior to proceeding.

3. Precautions

The Stabilizer Soft Tissue Anchor is intended for use by surgeons familiar with soft tissue and bone attachment techniques. The patient must be cautioned against early weightbearing and/or premature ambulation as this could lead to loosening or failure of the implant or suture attachments. Standard postoperative practices for the treatment and rehabilitation of repaired joints must be followed.

    1. Complications
      Potential complications with the The Stabilizer Soft Tissue Anchor include, but are not limited to, the following: infection, osteomyelitis, suture breakage, implant breakage, implant pull-out, reoperation, revision or explant.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

The product design, material of construction, and function as a soft tissue anchor is substantially equivalent to the FDA cleared predicate device.
