Intended Use

The Fixion Unipolar Modular Hemi-Hip System is intended for use as a hemi hip replacement in case of:

  • Femoral head/neck fractures or non-unions
  • Aseptic necrosis of the femoral head/neck
  • Osteo-, rheumatoid, and post-traumatic arthritis of the hip, with minimal acetabular involvement
Device Description

The Fixion UH is a modular hemi-hip replacement system, which is composed of a metal stem and neck part ("stem") with an expandable femoral head in various dimensions from metal or Alumina ceramic for use during partial hip replacement.

AI/ML Overview

The provided text describes a 510(k) submission for the Fixion™ Unipolar Modular Hemi-Hip System (Fixion UH), focusing on its substantial equivalence to predicate devices and adherence to performance standards. However, it does not contain information about specific acceptance criteria or a study that rigorously proves the device meets those criteria in the context of AI/ML or diagnostic performance. Instead, it details the engineering and manufacturing standards for an orthopedic implant.

Therefore, many of the requested categories for AI/ML device performance cannot be filled based on the provided text. I will address the sections that can be informed by the document.

Information Not Available in the Provided Text (Pertaining to AI/ML or Diagnostic Studies):

The provided 510(k) summary is for a physical medical device (a hemi-hip system) and therefore does not contain the following information typically found in submissions for AI/ML or software as a medical device (SaMD):

  1. Sample size used for the test set and the data provenance: Not applicable. The "test set" here refers to physical bench testing, not a dataset for AI/ML.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for an AI/ML diagnostic algorithm.
  3. Adjudication method for the test set: Not applicable.
  4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is an implant, not a diagnostic aid.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable to an orthopedic implant's performance verification in this context. The "ground truth" would be the engineering specifications and ISO standards met by material and mechanical properties.
  7. The sample size for the training set: Not applicable for an orthopedic implant.
  8. How the ground truth for the training set was established: Not applicable for an orthopedic implant.

Trade/Proprietary Name

Fixion™ Unipolar Modular Hemi-Hip System ("Fixion UH")

Classification Name

Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis

Predicate Devices

The Fixion UH intended use, materials and accessories are substantially equivalent to those used in Depuy Orthopeadics' Elite® Modular Hip System and S-ROM Total Hip System, as well as Disc-O-Tech's Fixion™ Interlocking PF Intramedullary Nailing System. The Fixion UH is also substantially equivalent to Link America, Inc.'s Link® Reconstruction Hip and to Smith and Nephew's Biolox® Alumina Ceramic Femoral Head.

Performance Standards

The Fixion UH conforms to the requirements of ISO 7206-8 (1995) "Implants for Surgery Partial and Total Hip Joint Prostheses - Part 8: Endurance Performance of Stemmed Femoral Components with Application of Torsion."

System Description

ystem Description
The Fixion UH is a modular hemi-hip replacement system, which is composed The I Mori of I is a land neck part ("stem") with an expandable femoral of a metazie relition from in various dimensions from metal or Alumina ceramic for use during partial hip replacement.

Substantial Equivalence

The Fixion UH System has substantially equivalent intended use and indications for use as the Elite Modular Hip System and the other predicates, i.e., replacement of hips.

The performance characteristics of the Fixion UH have been tested and found to meet the specifications through a series of bench tests.

The Stem of the Fixion UH Unipolar Hemi-Hip System, like the Fixion™ PF Intramedullary Nail, is made of 316LVM Stainless Steel. The cross section of the Fixion UH stem body and the Fixion Interlocking PF Intramedullary nail is identical and circular with reinforcement bars.

Fixation of the Fixion UH Stem to the femur is further enhanced by its inflation with sterile saline similar to the Fixion PF Nail and results in the abutment of the 4 reinforcement bars to the medullary canal wall. Rotational and axial stability is aided by the shape of the Stem Neck. The inflation of the Fixion UH Stem with saline, which is a non-compressible biocompatible fluid, is identical to the cleared Fixion PF Nail and does not raise any new safety and efficacy issues.

(a)
Identification. A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.(b)
Classification. Class II.
