Section 1: Applicable for the GLOBAL UNITE™ Platform Shoulder System with GLOBAL UNITE™ Standard or Revision/Long Humeral Stem Implants
The GLOBAL UNITE Platform Shoulder System is intended for cemented total or hemi-shoulder arthroplasty in treatment of the following:
- · A severely painful and/or disabled ioint resulting from osteoarthritis or rheumatoid arthritis
- · Fracture 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
- · Irreducible 3- and 4-part fractures of the proximal humerus
- · Ununited humeral head fractures
- Avascular necrosis of the humeral head
- · Other difficult clinical problems where shoulder arthrodesis or not acceptable (e.g., revision of a failed primary component)
- Hemi-shoulder arthroplasty is also indicated for:
- Deformity and/or limited motion
The GLOBAL UNITE™ Reverse Fracture Epiphyseal Component, in conjunction with components from the existing DELTA XTEND™ Reverse Shoulder System and GLOBAL UNITE Platform Shoulder System, is indicated for use in a grossly rotator cuff deficient glenohumeral joint with severe arthropathy failed joint replacement with a gross rotator cuff deficiency. The patient's joint must be anatomically suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. It is intended for cemented reverse shoulder arthroplasty in treatment of the following:
· Fracture 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
- · Irreducible 3- and 4-part fractures of the proximal humerus
· Ununited humeral head fractures
The GLOBAL UNITE Reverse Fracture Epiphyseal Component is only intended for use in the treatment of proximal humeral fractures. Bone preparation instrumentation has not been developed to accommodate its use in a non-fracture press-fit application.
GLOBAL UNITE Humeral Stems, in conjunction with existing DELTA XTEND Epiphyseal Components, are indicated for use in reverse shoulder arthroplasty in treatment of a grossly deficient rotator cuff joint with severe arthropathy or a previously failed joint replacement with a grossly deficient rotator cuff joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. When used in a total shoulder arthroplasty, the GLOBAL UNITE™ Implants are to be used with DePuy glenoid components. The glenoid components are for cemented use only. GLOBAL UNITE Humeral Implants are for cemented or uncemented use.
When used in a reverse shoulder arthroplasty, the GLOBAL UNITE and DELTA XTEND™ Humeral Implants are to be used with the HA-coated DELTA XTEND Metaglene Devices. The metaglene implants are intended for uncemented use only with additional screw fixation. The HA-coated DELTA XTEND Humeral Implants are intended for uncemented use only. Porous-coated epiphyses are intended for cemented or uncemented use. GLOBAL UNITE Humeral Implants are for cemented or uncemented use.
Section 2: Applicable for the GLOBAL UNITE™ Platform Shoulder System with GLOBAL UNITE™ Short Humeral Stem Implants
GLOBAL UNITE Short Humeral Stem Implants are for uncemented use only. The GLOBAL UNITE Platform Shoulder System with Short Humeral Stem is intended for uncemented total or hemi-shoulder arthroplasty in treatment of the following:
- · A severely painful and/or disabled joint resulting from osteoarthritis or rheumatoid arthritis
- · Other difficult clinical problems where shoulder arthrodesis or resection arthroplasty are not acceptable (e.g. revision of a failed primary component)
- Hemi-shoulder arthroplasty is also indicated for:
- Deformity and/or limited motion
GLOBAL UNITE Short Humeral Stems, in conjunction with existing DELTA XTEND Epiphyseal Components, are indicated for use in reverse shoulder arthroplasty in treatment of a grossly deficient rotator cuff joint with severe arthropathy or a previously failed joint replacement with a grossly deficient rotator cuff joint. The patient's joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device.
When used in a total shoulder arthroplasty, the GLOBAL UNITE Implants are to be used with DePuy glenoid components. The glenoid components are for cemented use only.
When used in a reverse shoulder arthroplasty, the GLOBAL UNITE and DELTA XTEND Humeral Implants are to be used with the HA-coated DELTA XTEND Metaglene Devices. The metaglene implants are intended for uncemented use only with additional screw fixation. The HA-coated DELTA XTEND Humeral Implants are intended for uncemented use only. Porous-coated epiphyses are intended for cemented use. GLOBAL UNITE Short Humeral Stem Implants are for uncemented use only.
The Global Unite Platform Shoulder System is comprised of humeral stem, humeral head, suture collar and epiphyseal (anatomical or reverse) components.
The subject Global Unite Short Stems are designed to conserve geometry and features of the predicate Global Unite standard stems while removing the distal segment of the stem body.
This is a 510(k) premarket notification for a medical device (GLOBAL UNITE™ Platform Shoulder System), which aims to demonstrate substantial equivalence to legally marketed predicate devices, rather than establishing safety and effectiveness through clinical studies with acceptance criteria, as would typically be done for novel devices or those undergoing PMA.
Therefore, the document does not contain the information requested regarding acceptance criteria studies, such as:
- A table of acceptance criteria and reported device performance.
- Sample sizes, data provenance for a test set, expert qualifications, or adjudication methods for ground truth because no clinical evaluation of a diagnostic or AI algorithm is presented.
- Multi-reader multi-case (MRMC) comparative effectiveness studies.
- Standalone (algorithm-only) performance results.
- Type of ground truth used (e.g., expert consensus, pathology, outcomes data).
- Sample size for training sets or how ground truth for training sets was established.
Instead, this submission primarily relies on non-clinical testing and evaluations (biocompatibility, dimensional/geometrical equivalency, fatigue strength, tolerance analysis, torque testing, and MRI compatibility) to demonstrate that the new device is as safe and effective as the predicate devices. The conclusion explicitly states: "The results of the non-clinical testing and evaluations have demonstrated that the subject device is as safe and effective as the predicate device and therefore, substantially equivalent to the predicate device."
The relevant "Testing Data" provided in the 510(k) Summary (page 7 of the document) are:
- Summary of non-clinical study: "Biocompatibility evaluation per ISO10993-1. Dimensional and geometrical equivalency analysis, fatigue strength evaluation, tolerance analysis and torque testing are conducted. MRI compatibility evaluation is conducted for MRI labeling."
- Summary of animal study: "Animal study was not necessary."
- Summary of clinical study: "Clinical study was not necessary."
This type of submission focuses on comparing the new device's technical characteristics and performance to existing, legally marketed devices through engineering and materials testing, rather than through clinical trials demonstrating diagnostic or therapeutic efficacy against a defined ground truth.
§ 888.3660 Shoulder joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing 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)
