Intended Use

Total or hemi-shoulder replacement is indicated for:

  1. A severely painful and/or disabled joint resulting from osteoarthritis, traumatic arthritis or rheumatoid arthritis;
  2. Fracture-dislocations of the proximal humerus where the articular surface is severely comminuted, separated from its blood supply or where the surgeon's experience indicates that alternative methods of treatment are unsatisfactory;
  3. Other difficult clinical problems where shoulder arthrodesis or resection arthroplasty are not acceptable (e.g., revision of a failed primary component).

Hemi-shoulder replacement is also indicated for:

  1. Ununited humeral head fractures;
  2. Avascular necrosis of the humeral head.

Only the titanium alloy humeral stem components and the cobalt-chrome alloy humeral stem components, which are marketed under the Global Shoulder name, are intended for press-fit or cemented fixation. The glenoid components are for cemented use only.

Device Description

The Global Shoulder components, which are the subjects of this submission, consist of a humeral body (stem) and a humeral head. Like the predicate devices, the components are modular in that they employ a morse-type taper lock system, the modular head having the male taper and the body with the female taper. Both components (head and body) will be made from Co-Cr-Mo alloy.

The subject Global humeral stem is similar to the current Global humeral stem in that there are four proximal fins, a proximal collar, and a fluted distal stem. The fins are perforated to accommodate the sutures necessary to reconstruct the proximal humerus.

The Global humeral head is similar to the current Global head in that it is fitted with an identical locking taper, is semi-spherical in design, and it has similar head sizes and heights. The size range will allow options for joint tensioning and restoration of normal joint biomechanics.

Modifications and Reason: Although the currently marketed design already includes the indication for use in fracture cases, the need for a smaller proximal humeral stem has been identified for those patients with smaller metaphyses and for use in fracture cases when the predicate Global humeral component is too large for the particular patient. DePuy believes the subject humeral components, containing the following described modifications, fill this need.

  • The proximal humeral body has been reduced in the A/P and M/L dimensions to ease repositioning of the fractured humeral tuberosities.
  • The lateral fin has a reduced profile to prevent contact with the biceps tendon and to avoid tilting the prosthesis in a varus orientation.
  • The medial fin has a suture hole added for passing of sutures to reposition fractured tuberosities.
  • The lateral fin has one centrally located suture hole versus the three suture holes in the current design.
  • The collar diameter has been reduced and contains a flat profile to mate with humeral heads.
  • The humeral head has been modified to contain a recess in the undersurface in order to mate with the collar of the humeral stem component. The collar/head design reduces collar/head gap and increases the effective articular surface area.
AI/ML Overview

The provided text is a 510(k) Summary of Safety and Effectiveness for the DePuy Global™ Shoulder device, specifically the Global™ Fx Humeral Stem and Global™ Advantage® Humeral Head.

This document describes the device, its intended use and indications, and the basis for its substantial equivalence to previously cleared devices. It does not contain information about acceptance criteria or a study proving that the device meets those criteria, as one would typically find for a medical AI or diagnostic device.

Instead, this document focuses on demonstrating that the modified components (Global™ Fx Humeral Stem and Global™ Advantage® Humeral Head) are substantially equivalent to existing, already-cleared Global Shoulder components (K911686, K914695). The "acceptance criteria" here implicitly refer to the FDA's regulatory requirements for substantial equivalence for a medical device that does not involve AI or a diagnostic algorithm.

Therefore, I cannot provide the requested information in the format because the provided document does not contain:

  • A table of acceptance criteria and reported device performance directly related to an AI/diagnostic algorithm.
  • Sample sizes for test sets, data provenance, or expert involvement for ground truth establishment.
  • Adjudication methods.
  • Information on Multi-Reader Multi-Case (MRMC) comparative effectiveness studies.
  • Standalone algorithm performance studies.
  • Training set details or ground truth establishment for a training set.

The "study" in this context is the comparison of design, materials, manufacturing processes, indications for use, and intended use to predicate devices, as opposed to a clinical performance study with statistical metrics.

Summary of Device and Basis for Equivalence (as presented in the document):

Device: Global™ Fx Humeral Stem and Global™ Advantage® Humeral Head (humeral stem and head components for shoulder arthroplasty).

Basis of Substantial Equivalence:
The document states that the fundamental scientific technology has not changed from previously FDA-cleared Global Shoulder humeral components (K911686). The intended use and indications for use also remain unchanged. The new components address a need for a smaller proximal humeral stem for patients with smaller metaphyses and fracture cases.

Modifications (minor design changes):

  • Reduced A/P and M/L dimensions of the proximal humeral body.
  • Reduced profile of the lateral fin.
  • Added a suture hole to the medial fin.
  • Changed lateral fin to one centrally located suture hole (from three).
  • Reduced and flattened collar diameter.
  • Humeral head modified with a recess in the undersurface to mate with the stem collar.

Conclusion for Equivalence:
DePuy believes the modified components are substantially equivalent to the predicate devices (K911686 and K914695) based on conformance with design control procedures (21 CFR 820.30), similarities in design, commonly used materials, sterilization processes, indications for use, and intended use. The FDA concurred with this assessment for substantial equivalence (K984541).

INTENDED USE:

The subject humeral stem and humeral head are intended for use in total or hemiarthroplasty. When used for total shoulder arthroplasty, the subject components are designed to be used with the existing Global cemented glenoid components cleared in K905786 & K914000. The humeral stem is intended to be used with bone cement or in press-fit applications (cementless).

Summary of Safety and Effectiveness (Continued)

BASIS OF SUBSTANTIAL EQUIVALENCE:

The fundamental scientific technology of the humeral stem and head has not changed from the FDA cleared (K911686) Global Shoulder humeral components. The intended use and indications for use of the subject Global humeral body and head, as described in its labeling has not changed from the FDA cleared (K911686) Global Shoulder devices. The addition of the Global Fx Stem to the Global Shoulder line does not require an application for a new indication because the fracture indication already exists for the currently marketed design. Like the predicate devices in K911686, the humeral head will be manufactured from cobalt chrome alloy. The humeral stem will be manufactured from F-75 cobalt chrome alloy, identical to the humeral component cleared in K914695. With the exception of the minor design modifications previously described, the subject humeral stem and humeral head are identical to the Global Shoulder devices cleared in K911686 and K914695.

Based on conformance with the design control procedures requirements as specified in 21 CFR 820.30, similarities of design, commonly used materials, sterilization processes, indications for use, and intended use, DePuy believes that the subject humeral stem and humeral head components are substantially equivalent to the FDA cleared (K911686 and K914695) Global Shoulder components.

The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
