The 510(k) summary describes a mechanical implant (shoulder prosthesis components) and does not mention any software, algorithms, or data processing capabilities that would indicate the use of AI or ML. The focus is on material properties, dimensions, and compatibility with existing components.
Yes
Explanation: The device is a reverse shoulder prosthesis intended for the treatment of humeral fractures and total shoulder replacement, directly treating a medical condition and restoring function.
No
The device described is a shoulder prosthesis, indicated for surgical implantation to treat severe shoulder conditions. It is an implantable medical device, not a tool used to diagnose conditions.
No
The device description clearly outlines physical implant components made of CoCrMo and Ti alloy, which are hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a Reverse Shoulder Prosthesis used for surgical treatment of humeral fractures and shoulder replacement. This is a surgical implant, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details the components of a shoulder implant system, including glenospheres, baseplates, and screws. These are physical components designed to be implanted in a patient's body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) to provide information about a physiological state, health, or disease. The device's function is mechanical replacement of a joint.
In summary, the device is a surgical implant used for treatment, not a diagnostic tool used for in vitro testing.
N/A
Intended Use / Indications for Use
The Reverse Shoulder Prosthesis is indicated for treatment of humeral fractures and for primary or revision total shoulder replacement in patients with a grossly deficient rotator cuff shoulder joint with severe arthropathy failed joint replacement with a grossly rotator cuff deficient shoulder joint.
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.
The glenoid baseplate is intended for cementless application with the addition of screws for fixation.

Device Description
The Lateralized Glenosphere are line extensions to the Medacta Shoulder Reverse System (K170452) and are compatible with the other Medacta cleared products Threaded Glenoid Baseplate (K171058), Glenoid Polyaxial Non-Locking Screws (K181826) and the Short Humeral Stem (K180089).
The Lateralized Glenosphere implants subject of this submission are comprised of the following products (9 sizes):
- Size Ø 32: to be coupled with Medacta Glenoid Baseplate Ø 22 or Ø 24.5mm
- . Size Ø 36: to be coupled with Medacta Glenoid Baseplate Ø 22 or Ø 24.5 or Ø27mm
- Size Ø 39: to be coupled with Medacta Glenoid Baseplate Ø 24.5 or Ø27mm
- . Size Ø 42: to be coupled with Medacta Glenoid Baseplate Ø 24.5 or Ø27mm
The Lateralized Glenosphere implants are part of the Medacta Shoulder Reverse System. The Medacta Shoulder Reverse System consists of the following components:
- Humeral Diaphysis Cemented;
- Humeral Diaphysis - Cementless;
- Humeral Reverse Metaphysis;
- Humeral Reverse HC Liner (also referred to as PE Liner);
- . Glenoid Baseplate - Pegged;
- Glenoid Baseplate Threaded;
- Glenosphere;
- . Glenoid Polyaxial Locking Screw;
- . Glenoid Polyaxial Non-Locking Screw;
- Reverse Metaphysis Screw; and

The glenosphere is attached to the glenoid baseplate and secured by means of a taper connection and a fastening screw.
The purpose of the current submission is to gain clearance for the Lateralized Glenospheres, whose center is more lateralized respect to Medacta predicate device Glenosphere (Medacta Shoulder Reverse System - K170452).
The new option of lateralization allows the surgeon to intraoperatively select the desired level of ROM and resulting joint tension based on the patient's anatomy.
The Lateralized Glenosphere is made of CoCrMo ISO 5832-12 (Second Edition 2007-05-01) Implants For Surgery - Part 12: Wrought Cobalt- Chromium-Molybdenum Alloy [Including: Technical Corrigendum 1 (2008)], while the Glenosphere screw packed with the implant is made of Ti alloy (Ti-6A1-4V), enhanced with Type-II anodization, according to ISO 5832-3:2016 Implants For Surgery -Metallic Materials - Part 3: Wrought Titanium 6-Aluminum 4-Vanadium Alloy.

V. Indications for Use
The Reverse Shoulder Prosthesis is indicated for treatment of humeral fractures and for primary or revision total shoulder replacement in patients with a grossly deficient rotator cuff shoulder joint with severe arthropathy or a previously failed joint replacement with a grossly rotator cuff deficient shoulder 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.
The glenoid baseplate is intended for cementless application with the addition of screws for fixation.
VI. Comparison of Technological Characteristics
The Lateralized Glenosphere and the main predicate device (cleared within Medacta Shoulder Reverse System) K170452, Medacta International SA share the following characteristics:
- indications for use; ●
- material of construction:
- sizes
- eccentricity of the COR (Center Of Rotation);
- biocompatibility;
- device usage:
- sterility;
- shelf life; and
- packaging.
The Lateralized Glenosphere is technologically different from the main predicate device as follows:
- lateralization of the COR.
The subject Lateralized Glenosphere has the same technological characteristics of the Medacta predicate device Glenosphere (cleared within Medacta Shoulder Reverse System) K170452, with the only exception of the grade of lateralization of the COR, feature shared with the other predicate AEQUALIS™ REVERSED II Shoulder Prosthesis (K112144). This new option of lateralization allows the surgeon to intraoperatively select the desired level of ROM and resulting joint tension based on the patient's anatomy.
Biocompatibility testing conducted on the main predicate device for the same materials supports the biological safety of the Lateralized Glenosphere. Subject and predicate devices are manufactured from the following material: CoCrMo ISO 5832-12 (Second Edition 2007-05-01) Implants For Surgery – Part 12: Wrought Cobalt- Chromium-Molybdenum Alloy [Including: Technical Corrigendum 1 (2008)], while the Glenosphere screw packed with the implant is made of Ti alloy (Ti-6Al-4V), enhanced with Type-II anodization, according to ISO 5832-3:2016 Implants For Surgery - Metallic Materials - Part 3: Wrought Titanium 6-Aluminum 4-Vanadium Alloy.

VII. Performance Data
Testing was conducted according to written protocols with acceptance criteria that were based on standards. The following mechanical studies were performed in substantial equivalence determination:
Non-Clinical Studies:
- Characterization Tests .
- o Design Validation Report.
- Performance Tests
- Assessment In Reverse Configuration With A Lateralized o Micromotions Glenosphere: ASTM F2028-17: Standards Test Methods For Dynamic Evaluation of Glenoid Loosening or Disassociation;
- Fatigue Test On Threaded Glenoid Reverse Construct With A Lateralized о Glenosphere: ASTM F1378-17 - Standard Specifications for Shoulder Prosthesis; and
- Rationale, Lateralized Glenosphere Wear Assessment. o
- Pyrogenicity
- Bacterial Endotoxin Test (LAL test) was conducted according to European o Pharmacopoeia §2.6.14 (which is equivalent to USP chapter ) and pyrogen test according to USP chapter for pyrogenicity determination; and
- the subject devices are not labeled as non-pyrogenic or pyrogen free. O
Clinical Studies:

VIII. Conclusion
Based on the above information, the Lateralized Glenospheres are substantially equivalent to the identified predicate devices.
Substantial equivalence has been demonstrated through a comparison of intended use, design, and technological characteristics, as well as performance evaluations. The Lateralized Glenosphere implants are as safe and effective as the predicate devices Medacta standard Glenosphere cleared under Medacta Shoulder Reverse System K170452 (predicate device) and Tornier AEQUALIS™ REVERSED II Shoulder Prosthesis (K112144).
