The document describes a mechanical implant system for shoulder arthroplasty and does not mention any software, algorithms, or AI/ML components. The performance studies are mechanical bench testing and a clinical study evaluating the implant's safety and effectiveness.
Yes
The device is a shoulder implant system intended to replace a severely painful and/or disabled joint, which inherently provides a therapeutic benefit by restoring function and alleviating pain due to osteoarthritis or traumatic arthritis.
No
The device is a shoulder implant system (prosthesis) used for total shoulder arthroplasty, which is a surgical treatment to replace the shoulder joint. Its intended use is for actual treatment of a condition rather than diagnosis.
No
The device description clearly states it is a "metaphyseal metal humeral component, a metal humeral head and an ultrahigh molecular weight polyethylene glenoid," which are physical implants, not software.
Based on the provided information, the Simpliciti™ Shoulder System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is for treating painful and/or disabled joints resulting from osteoarthritis or traumatic arthritis through surgical implantation. This is a therapeutic intervention, not a diagnostic test performed on samples outside the body.
- Device Description: The device is a physical implant (humeral component, humeral head, glenoid) made of various materials. It is designed to replace damaged joint components.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (blood, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
Therefore, the Simpliciti™ Shoulder System is a surgical implant, not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical performance bench testing (mechanical testing) was performed to demonstrate substantial equivalence to the predicate device.
CAD study to ensure acceptable geometry: Head geometry is comparable to the Aequalis humeral heads. Result: Acceptable.
Mechanical testing (fatigue): The nucleus shall survive a prescribed number of cycles at a prescribed load without fatigue, fracture, yielding, loosening. Result: Acceptable.
Mechanical testing (lever out): Qualitative Comparison to Aequalis Resurfacing Shoulder. Result: Acceptable.
Mechanical testing (pull out): Qualitative Comparison to Aequalis Resurfacing Shoulder. Result: Acceptable.
Mechanical testing (torque out): Qualitative Comparison to Aequalis Resurfacing Shoulder. Result: Acceptable.
Mechanical testing (taper disassociation testing): The Simpliciti Shoulder taper is equivalent to the taper of the Affiniti Shoulder System. Result: Acceptable.
X-ray overlay validation: No impingement of the fin geometry on the inner cortex of the metaphysis. Result: Acceptable.
The Simpliciti Shoulder System study was a prospective, single arm, multi-center study conducted at 14 sites in the US which enrolled 157 subjects (181 consented and screened). The purpose of the Simpliciti IDE study was to demonstrate safety and effectiveness of the Simpliciti system in total shoulder arthroplasty at 24 months. Subject outcomes were compared to results of a historical control group with a primary diagnosis of osteoarthritis or traumatic arthritis and implanted with a FDA cleared, Tornier stemmed humeral prosthesis. A subject was a success at 24 months if: there was no continuous radiolucent line around the prosthesis, the adjusted Constant score was > 85, they did not have revision surgery, and they did not have a system-related serious adverse event. Secondary objectives included quality of life, range of motion, strength, and radiographic device assessment.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
The percentage of subjects who met all four criteria is 88.74% with a lower one-sided 95% confidence bound of 83.59%. As the lower bound is greater than the percentage of success observed in the historic control (75% and the non-inferiority margin (10%), the null hypothesis is rejected in favor of the alternative hypothesis that the primary endpoint is greater than 75%.
All secondary QOL objectives, on average, reported patient improvement. Additionally, third party radiologists determined there were no instances of radiolucency, device migration, osteolysis, or subsidence of the glenoid component or nucleus.
There were 228 reported Adverse Events (AEs) occurring in 103 of the study subjects. Study investigators classified relatedness of all AEs as definitely related, possibly related, unknown relatedness, or not related to the study system or procedure. There were 22 (22/228, 9.6%) AEs in 21 subjects (21/157, 13.4%) that were considered related to the system or procedure. One (0.4%) AE for aseptic glenoid loosening was considered possibly related to the system. Ten (4.4%) events were reported as definitely related to the procedure and 11 (4.8%) were reported as possibly related to the procedure. Adverse events definitely related to the procedure included: infection (2), shoulder stiffness (2), paresthesia (2), ecchymosis (1), mental status changes (1), scarring (1), and keloid scar (1). Adverse events possibly related to the procedure included: paresthesia (4), weakness (2), tendonitis (1), pain (1), hematoma (1), arthrofibrosis (1), and osteoarthritis (1). All system or procedure related events were considered expected complications for total shoulder arthroplasty; thus, there were no Unanticipated Adverse Device Effects (UADEs).
There were a total of 55 reported serious AEs (SAEs). Three (3/55, 5.5%) SAEs were possibly (2/55, 3.6%) or definitely (1/55, 1.8%) related to the procedure and one (1/55, 1.8%) SAE was considered possibly related to the system. The aseptic glenoid loosening is the only SAE with a possible relationship to the system. The SAEs possibly related to the procedure included weakness (1) and arthrofibrosis (1) and the SAE definitely related to the procedure was an infection (1).
There were five subjects with revisions (3) and explants (2) of the Simpliciti system. The three revisions were for: nucleus upsize during initial implant (1), infection 4 weeks post-implant (1), and aseptic glenoid loosening 17 months post-implant (1). The two explants were for poor bone quality during the initial implant and subscapularis insufficiency 467 days post-implant.
The Simpliciti IDE study suggests that the Simpliciti system equivalently to currently marketed shoulder devices for the treatment of osteo- and traumatic arthritis.

IX. Clinical Study
The Simpliciti Shoulder System study was a prospective, single arm, multi-center study conducted at 14 sites in the US which enrolled 157 subjects (181 consented and screened). The purpose of the Simpliciti IDE study was to demonstrate safety and effectiveness of the Simpliciti system in total shoulder arthroplasty at 24 months. Subject outcomes were compared to results of a historical control group with a primary diagnosis of osteoarthritis or traumatic arthritis and implanted with a FDA cleared, Tornier stemmed humeral prosthesis. A subject was a success at 24 months if: there was no continuous radiolucent line around the prosthesis, the adjusted Constant score was > 85, they did not have revision surgery, and they did not have a systemrelated serious adverse event. Secondary objectives included quality of life, range of motion, strength, and radiographic device assessment.
The percentage of subjects who met all four criteria is 88.74% with a lower one-sided 95% confidence bound of 83.59%. As the lower bound is greater than the percentage of success observed in the historic control (75% and the non-inferiority margin (10%), the null hypothesis is rejected in favor of the alternative hypothesis that the primary endpoint is greater than 75%.

All secondary QOL objectives, on average, reported patient improvement. Additionally, third party radiologists determined there were no instances of radiolucency, device migration, osteolysis, or subsidence of the glenoid component or nucleus.
There were 228 reported Adverse Events (AEs) occurring in 103 of the study subjects. Study investigators classified relatedness of all AEs as definitely related, possibly related, unknown relatedness, or not related to the study system or procedure. There were 22 (22/228, 9.6%) AEs in 21 subjects (21/157, 13.4%) that were considered related to the system or procedure. One (0.4%) AE for aseptic glenoid loosening was considered possibly related to the system. Ten (4.4%) events were reported as definitely related to the procedure and 11 (4.8%) were reported as possibly related to the procedure. Adverse events definitely related to the procedure included: infection (2), shoulder stiffness (2), paresthesia (2), ecchymosis (1), mental status changes (1), scarring (1), and keloid scar (1). Adverse events possibly related to the procedure included: paresthesia (4), weakness (2), tendonitis (1), pain (1), hematoma (1), arthrofibrosis (1), and osteoarthritis (1). All system or procedure related events were considered expected complications for total shoulder arthroplasty; thus, there were no Unanticipated Adverse Device Effects (UADEs).
There were a total of 55 reported serious AEs (SAEs). Three (3/55, 5.5%) SAEs were possibly (2/55, 3.6%) or definitely (1/55, 1.8%) related to the procedure and one (1/55, 1.8%) SAE was considered possibly related to the system. The aseptic glenoid loosening is the only SAE with a possible relationship to the system. The SAEs possibly related to the procedure included weakness (1) and arthrofibrosis (1) and the SAE definitely related to the procedure was an infection (1).
There were five subjects with revisions (3) and explants (2) of the Simpliciti system. The three revisions were for: nucleus upsize during initial implant (1), infection 4 weeks post-implant (1), and aseptic glenoid loosening 17 months post-implant (1). The two explants were for poor bone quality during the initial implant and subscapularis insufficiency 467 days post-implant.
The Simpliciti IDE study suggests that the Simpliciti system equivalently to currently marketed shoulder devices for the treatment of osteo- and traumatic arthritis.
X. Conclusions
The Simpliciti Shoulder System described in this section has the same intended use and the same fundamental scientific technology as the cleared Affiniti Shoulder System. Based on the testing presented for the design differences between the subject and predicate devices, Tornier concludes that subject device is substantially equivalent to the predicate device.
