S-11 SMR TT Hybrid Glenoid and Cementless Finned Short Stem
Study Details
Study Description
Brief Summary
Post-market, prospective, non randomized, open label, multicentre, clinical study analysing outcomes of shoulder arthroplasty with SMR TT Hybrid Glenoid with or without SMR Cementless Finned Short Stem

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| SMR TT Hybrid Glenoid without Cementless Finned Short Stem Patients implanted with SMR TT Hybrid Glenoid without Cementless Finned Short Stem |
Device: SMR TT Hybrid Glenoid without Cementless Finned Short Stem
The subject SMR Hybrid Glenoid System and SMR cementless finned short stem is intended for both primary or revision anatomic and reverse shoulder joint replacement. The glenoid components when used as part of an anatomic shoulder replacement are intended for cemented fixation.

Device: SMR TT Hybrid Glenoid with Cementless Finned Short Stem
The subject SMR Hybrid Glenoid System and SMR cementless finned short stem is intended for both primary or revision anatomic and reverse shoulder joint replacement. The glenoid components when used as part of an anatomic shoulder replacement are intended for cemented fixation.
The fins are intended to enhance press-fit fixation. The same proximal morse taper is used for coupling to the same humeral bodies in the SMR Shoulder System. The SMR finned short stem is intended for cementless fixation.

Outcome Measures
Primary Outcome Measures
- Proportion of patients reaching a clinical progression from baseline to 24-month follow-up [24 Months]
The primary endpoint consists of the proportion of patients reaching a clinical progression from baseline to 24-month follow-up measured as: Constant score improvement of greater than 10; Adjusted Constant score greater than or equal to 54.
Secondary Outcome Measures
- Measure American Shoulder and Elbow Surgeons Shoulder Score (ASES) [Baseline to 24 and 60 Months]
The ASES questionnaire is composed of both a physician-rated component and a patient-reported component. The patient questions focus on joint pain, instability, and activities of daily living. Scores range from 0 to 100 with a score of 0 indicating a worse shoulder condition and 100 indicating a better shoulder condition.
- Measure Oxford shoulder score [Baseline to 24 and 60 Months]
Oxford Shoulder Score (OSS) is a 12-item patient-reported PRO specifically designed and developed for assessing outcomes of shoulder surgery.
- Measure Constant Score [Baseline to 24 and 60 Months]
The Constant-Murley score (CMS) is a 100-points scale composed of a number of individual parameters. These parameters define the level of pain and the ability to carry out the normal daily activities of the patient. The higher the score, the higher the quality of the function.
- Measure Simple Shoulder Test [Baseline to 24 and 60 Months]
Simple Shoulder Test (SST) is a series of 12 "yes" or "no" questions the patient answers about the function of the involved shoulder. The answers to these questions provides a standardized way of recording the function of a shoulder before and after treatment. The difference between the shoulder function before treatment and after the recovery period is the effectiveness of the treatment.
- Measure Patient Satisfaction [Baseline to 24 and 60 Months]
The satisfaction of the patients with regard to the effectiveness of the prosthetic treatment is graded on a scale from 1 to 5
- Stability of the SMR TT hybrid glenoid component with or without SMR cementless finned short stem [Immediately postoperative to 24 Months]
Rate of symptomatic radiolucent lines, loosening and subsidence ≥2 mm
- System conversion rate, intended as a conversion within the SMR system from anatomic to reverse [24 Months]
The SMR shoulder system is a modular system and in case of evolution of the pathology it may be easily converted from one configuration to another.
- Failure rate, intended as removal of the SMR TT hybrid glenoid component [Immediately postoperative to 24 Months]
A removal of the glenoid component is intended as a revision and a failure of the implant.
- Failure rate, intended as removal of the SMR cementless finned short stem [Immediately postoperative to 24 Months]
A removal of the stem component is intended as a revision and a failure of the implant.
- Incidence of device-related AE/SAE (ADE/SADE) [Immediately postoperative to 24 and 60 Months]
Device Related Adverse Events/Serious Adverse Events, device deficiencies, malfunctions and use errors at all follow-up time points
- Survival rate (Kaplan-Meier) [60 Months]
