The document describes a mechanical shoulder implant system and its components. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML. The performance studies are mechanical tests, not related to algorithmic performance.
Yes
The device is intended for partial or total shoulder joint replacement, which is a therapeutic intervention to treat conditions like degenerative joint disease, fractures, or failed implants, thereby alleviating symptoms and restoring function.
No
The device is a shoulder joint replacement system, intended for surgical implantation to replace a damaged shoulder joint. It is a therapeutic device, not one used to diagnose conditions.
No
The device description clearly details physical components like bone screws and baseplates made of metal and Trabecular Titanium, which are hardware.
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).
- Device Description: The description details bone screws and a glenoid component, which are physical implants.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis. IVDs are typically used in laboratories or point-of-care settings for diagnostic purposes.
The device described is a surgical implant used for orthopedic procedures, not a diagnostic test performed in vitro.

Intended Use / Indications for 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);
- . glenoid arthrosis without excessive glenoid bone loss: A1, A2 and B1 according to Walch classification (SMR TT Hybrid Glenoid only).
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 SMR TT Hybrid Glenoid Reverse Baseplate must not be used in cases of excessive glenoid bone loss and/or when bone graft is needed.
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.
The Anatomic glenoid construct consists of an all polyethylene glenoid, a polyethylene glenoid with metal peg or a metal back assembled with a liner; the Reverse glenoid consists or of ð peg/baseplate/glenosphere construct.
On the glenoid side, the fixation of the all polyethylene glenoid, the polyethylene glenoid with metal peg or the metal back determines if the construct is cemented or uncemented.

Device Description
Bone Screws are characterized by a 5,0 mm diameter (new device) and they are used in combination with SMR TT Augmented 360 Baseplate (K191746/K200171) to fix the baseplate to the glenoid bone.
The SMR TT Augmented 360 Baseplate is a metal back glenoid component coupled to a peg made of Trabecular Titanium, intended for uncemented use with the addition of bone screws for fixation to the bone. This glenoid component is part of the SMR TT Augmented Glenoid System (K191746/K200171) that is a modular system intended to be used in combination with previously cleared components of the SMR Reverse Shoulder System. The system consists of a modular glenoid component to be used in total shoulder replacement in a reverse shoulder configuration.

The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs are intended for cemented and uncemented use as specified in the following table.
In the Anatomic shoulder the humeral consists of the humeral stem, the humeral body, the adaptor taper and the humeral head. In the Reverse shoulder the humeral 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 with metal peg or a metal back assembled with a liner; the Reverse glenoid consists of a metal back/connector/glenosphere/glenosphere construct.

Predicate Devices:
- SMR TT Augmented Glenoid System (Limacorporate, K191746/K200171) ●
- . Tornier 5.0mm peripheral screw (K161742)
Summary of technology comparison:
Bone Screws dia. 5.0 mm are identical in material, manufacturing process, packaging. sterilization to the Bone screws dia. 4,5 mm and Bone Screws dia. 6,5 mm cleared in K191746/K200171.
The indications for use for Bone Screws dia. 5,0 mm are the same as the indications for use of the system with which they are used to.
Non-clinical testing
Mechanical testing had demonstrated the device's ability to perform substantially equivalent to the predicate device in:
- Torsional test, driving torque test, pull-out test for bone screws (ASTM F543)
- Dynamic Evaluation of the Glenoid Loosening or Disassociation (ASTM F2028)
Clinical testing
Clinical testing was not necessary to demonstrate substantial equivalence of Bone Screws dia. 5,0 mm to the predicate device.
Conclusions
The 5,0 mm Bone Screws (Subject Device System) described in this section has an equivalent intended use and same functional technology as previously cleared bone screws, primarly the ones described in K200171. Based on the testing data provided and description of the differences between the subject and predicated devices. LimaCorporate concludes that the subject device is substantially equivalent to the predicate device.
