Intended Use
The SMR Shoulder System is intended for partial or total, primary or revision shoulder joint replacement. The SMR Anatomic Shoulder System is indicated for partial or total, primary or revision shoulder joint replacement in patients suffering from disability due to: - non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis; - inflammatory degenerative joint disease such as rheumatoid arthritis; - treatment of acute fractures of the humeral head that cannot be treated with other fracture fixation methods: - revision of a failed primary implant; - cuff tear arthropathy (CTA Heads only). The Large Resection Stems (not available in the US) are indicated for oncology applications. The SMR Reverse Shoulder System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator cuff deficient joint with severe arthropathy (disabled shoulder). The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs. The constructs are intended for cemented and uncemented use as specified in the following table. In the Anatomic shoulder the humeral construct consists of the humeral body, the adaptor taper and the humeral head. In the Reverse shoulder the humeral construct consists of the humeral stem, the reverse humeral body and the reverse liner. On the humeral side the fixation of the humeral stem determines if the construct is cemented or uncemented. The Anatomic glenoid construct consists of an all polyethylene glenoid or a metal back assembled with a liner while the Reverse glenoid construct consists of the metal back, the connector and the glenosphere. On the glenoid side, the fixation of the all polyethylene glenoid or the metal back determines if the construct is cemented or uncemented.
Device Description
The SMR 40mm Glenosphere is a Co-Cr-Mo glenosphere intended to be used with the 40mm standard UHMWPE reverse liner (standard or retentive) as part of the SMR Reverse Shoulder System (K110598). The SMR Reverse Shoulder System consists of a humeral stem, a reverse humeral body, a reverse liner, a metal-back glenoid, a glenosphere and a connector with screw. Bone screws are used for the fixation of the metal-back glenoid to the scapula. Humeral stems are provided for both cemented and cementless (K100858, K101263, K111212, K113523) fixation as well as reverse humeral bodies (K110598). The SMR Reverse Shoulder System metal back glenoids (K110598. K113254 and K133349) and glenospheres (K110598) are intended for uncemented pressfit use only with the addition of screws for fixation. SMR 40mm Glenosphere is made of CoCrMo alloy that conforms to ASTM F1537 - ISO 5832-12 in two (2) different designs: a standard glenosphere that can be centered with respect to the glenoid component or eccentrical glenosphere that provides offset. Both designs have a spherical shape of 40mm diameter and articulate with the standard 40mm ultra-high molecular weight polyethylene (ASTM F648 - ISO 5834-2) liners that are coupled to the humeral body. Two designs for the 40mm liners are available: standard and retentive. The 40mm glenospheres are coupled to a SMR metal-back glenoid (K113254, K133349) through a double male taper, one side of which is connected to the glenosphere while the other is coupled with the glenoid component. To increase the solidity of the system, a screw is used to link the glenosphere to the glenoid component. The screw is inserted through a hole on the surface of the glenosphere, passing through the internal cavity of the connector and then screwed to the metal-back. The SMR 40mm Liners are made from standard ultra-high molecular weight polyethylene conforming to ASTM F648 – ISO 5834-2. They are coupled to the SMR Reverse Humeral Bodies (K110598) via a taper. The liners are designed with a bevel cut in their inferior aspect to reduce the possibility of accidental contact between the polyethylene liner and the scapular bone during adduction - abduction movements. The 40mm liners are available in standard and retentive designs in three (3) thicknesses (STD, +3mm and +6mm) with the retentive liners characterized by a deeper spherical concavity than is present in the standard liners.

No
The document describes a mechanical implant system for shoulder replacement and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The device is a shoulder joint replacement system, which directly treats and replaces damaged joints, thus providing therapy for patients suffering from various degenerative and inflammatory joint diseases.

No

The SMR Shoulder System is an orthopedic implant for joint replacement, not a diagnostic tool. Its intended use is to replace damaged shoulder joints in individuals with various conditions, not to diagnose them.

No

The device description clearly details physical components made of Co-Cr-Mo alloy and UHMWPE, intended for surgical implantation as part of a shoulder joint replacement system. There is no mention of software as the primary or sole component.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant for replacing a shoulder joint. This is a medical device used in vivo (within the body), not in vitro (outside the body) for diagnostic purposes.
  • Device Description: The description details the materials and components of a prosthetic shoulder joint, including glenospheres, liners, stems, and screws. These are all physical components designed for surgical implantation.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, tissue, etc.), detecting biomarkers, or providing diagnostic information about a patient's condition.
  • Performance Studies: The performance studies focus on mechanical testing of the implant's durability and fatigue resistance, which is typical for surgical implants, not IVDs.

In summary, the SMR Shoulder System is a surgical implant, not a device used for in vitro diagnostic testing.

Description:

The SMR 40mm Glenosphere is a Co-Cr-Mo glenosphere intended to be used with the 40mm standard UHMWPE reverse liner (standard or retentive) as part of the SMR Reverse Shoulder System (K110598). The SMR Reverse Shoulder System consists of a humeral stem, a reverse humeral body, a reverse liner, a metal-back glenoid, a glenosphere and a connector with screw. Bone screws are used for the fixation of the metal-back glenoid to the scapula. Humeral stems are provided for both cemented and cementless (K100858, K101263, K111212, K113523) fixation as well as reverse humeral bodies (K110598). The SMR Reverse Shoulder System metal back glenoids (K110598. K113254 and K133349) and glenospheres (K110598) are intended for uncemented pressfit use only with the addition of screws for fixation.

SMR 40mm Glenosphere is made of CoCrMo alloy that conforms to ASTM F1537 - ISO 5832-12 in two (2) different designs: a standard glenosphere that can be centered with respect to the glenoid component or eccentrical glenosphere that provides offset. Both designs have a spherical shape of 40mm diameter and articulate with the standard 40mm ultra-high molecular weight polyethylene (ASTM F648 - ISO 5834-2) liners that are coupled to the humeral body. Two designs for the 40mm liners are available: standard and retentive.

The 40mm glenospheres are coupled to a SMR metal-back glenoid (K113254, K133349) through a double male taper, one side of which is connected to the glenosphere while the

6

other is coupled with the glenoid component. To increase the solidity of the system, a screw is used to link the glenosphere to the glenoid component. The screw is inserted through a hole on the surface of the glenosphere, passing through the internal cavity of the connector and then screwed to the metal-back.

The SMR 40mm Liners are made from standard ultra-high molecular weight polyethylene conforming to ASTM F648 – ISO 5834-2. They are coupled to the SMR Reverse Humeral Bodies (K110598) via a taper. The liners are designed with a bevel cut in their inferior aspect to reduce the possibility of accidental contact between the polyethylene liner and the scapular bone during adduction - abduction movements. The 40mm liners are available in standard and retentive designs in three (3) thicknesses (STD, +3mm and +6mm) with the retentive liners characterized by a deeper spherical concavity than is present in the standard liners.

The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs. The constructs are intended for cemented and uncemented use as specified in the following table.

In the Anatomic shoulder the humeral construct consists of the humeral stem, the humeral body, the adaptor taper and the humeral head. In the Reverse shoulder the humeral construct consists of the humeral stem, the reverse humeral body and the reverse liner. On the humeral side the fixation of the humeral stem determines if the construct is cemented or uncemented.

7

The Anatomic glenoid construct consists of an all polyethylene glenoid or a metal back assembled with a liner while the Reverse glenoid construct consists of the metal back, the connector and the glenosphere. On the glenoid side, the fixation of the all polyethylene glenoid or the metal back determines if the construct is cemented or uncemented.

*NOTE :

  • . In the US, the SMR Metal Backed Glenoid/Liner construct, used as part of the SMR Anatomic Shoulder Replacement, is intended for use with bone cement and should be used without bone screws.
  • . Outside the US, the SMR Metal Backed Glenoid/Liner construct, used as part of the SMR Anatomic Shoulder Replacement, is intended for uncemented use with the addition of screws for fixation.

  • . The SMR Metal Backed Glenoid/Connector/Glenosphere construct, used as part of the SMR Reverse Shoulder replacement, is intended for uncemented use with the addition of screws for fixation.
  • The SMR TT Metal Back is indicated for primary implant in anatomic or reverse total ● shoulder arthroplasty with poor glenoid bone quality or in revision case with consistent bone loss on the glenoid side. The implant is suitable for implantation with or without bone graft. These indications are not yet approved in the US.
  • . In the US the SMR TT Metal Back Baseplate used as part of the SMR Anatomic Shoulder Replacement, is intended for use with bone cement and should be used without bone screws: while when used as part of the SMR Reverse Shoulder replacement, is intended for uncemented use with the addition of screws for fixation.

Predicate Devices:

  • SMR Reverse Shoulder System (Limacorporate, K110598);
  • Promos Reverse Shoulder System (Plus Orthopedics, K081016); ●
  • Inverse/reverse Shoulder (Zimmer, K053274); ●
  • Delta Xtend Reverse Shoulder (DePuy, K091751).

Comparable Features to Predicate Device(s):

The SMR 40mm Glenosphere and Liner are similar to the predicate devices in terms of intended use, indications, design and materials. The SMR 40mm Glenosphere and the predicates are all intended for total primary or revision reverse shoulder joint replacement. All systems are provided with reverse liners and glenospheres of similar diameters that are intended to articulate together. In all the systems, the glenospheres are fixed to the glenoid bone through the use of a glenoid component and connector.

The components of the SMR 40mm Glenosphere and Liner are manufactured from the same or similar materials as the predicate devices.

Non-Clinical Testing:

The SMR 40mm Glenosphere was tested for fatigue resistance of the modular connection to the metal-back glenoid component. Mechanical testing was performed on worst case components or constructs. The testing results demonstrated the device's ability to perform under expected clinical conditions.

Clinical Testing:

Clinical testing was not necessary to demonstrate substantial equivalence of the SMR 40mm Glenosphere to the predicate devices.
