GLOBAL ICON Stemless Shoulder System Post Market Clinical Follow Up Study

Not Applicable

Terminated

Conditions: Post Traumatic Arthritis
Osteoarthritis

Registration Number: NCT03168672

Lead Sponsor: DePuy Orthopaedics

Brief Summary: This is a Post Market Clinical Follow Up (PMCF) study to monitor the safety and performance of the GLOBAL ICON stemless humeral component. The data gathered will be used to support post market surveillance of the device, and may potentially be used for additional market access purposes.

Detailed Description: This study will be multi-centre and non-comparative. Subjects will be recruited and followed up at similar intervals to reflect the standard clinical practice and intended population for wider use of the device.

157 non-randomised subjects will be recruited from approximately 15 sites. A maximum of 30 subjects may be recruited from one site. More than one implanting surgeon may recruit subjects at each site as a designated sub-Investigator.

The primary objective of this PMCF study is to confirm device survivorship of the GLOBAL ICON stemless humeral component at 24 months post-operative.

The secondary objectives include the evaluation of clinical performance, radiographic performance and safety outcomes at 3, 12, 24, 60 and 120 months post-operatively.

Tertiary endpoints in the study will include a mean change from baseline for the Adjusted Constant-Murley Score, the Oxford Shoulder Score, the EQ-5D-5L dimension score and EQ-VAS scores. Radiographic evidence of aseptic loosening and periprosthetic fracture survivorship of the GLOBAL ICON stemless humeral component will be assessed.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Overall Composite Clinical Success	At 24 months	Percentage of participants with overall composite clinical success at 24 months was reported. Composite success was achieved if each of the following criteria was met: (1) Radiographs indicated that there was no continuous radiolucent line (RLL) around the GLOBAL ICON stemless humeral component, with continuous RLL defined as a radiolucent line greater than (\>) 1millimeter (mm) in all five zones of either anterior-posterior (AP) or Axillary views (2) The adjusted Constant-Murley score was greater than 85, with the adjustment based on the method of Constant (3) No GLOBAL ICON humeral component was removed for any reason (4) There was no device-related serious adverse events.
Adjusted Constant-Murley Shoulder Assessment Score	24 Months	Constant-Murley Score on operative shoulder adjusted for gender and age. Please note that scores are adjusted to reflect gender and age of participants. The Constant-Murley score is divided into four subscales, including pain (15 points maximum), activities of daily living (20 points maximum), ROM (40 points maximum), and strength (25 points maximum). The higher the score, the higher the quality of function (minimum 0, maximum 100) Adjustment may lead to scores above 100 depending on age of group analyzed. The range for the Adjusted Constant-Murley score in a male participant is 0-178.6; the range for the Adjusted Constant-Murley score in a female participant is 0-192.3. Please note the calculations of the maximum Adjusted score assume a perfect score (100) in 100 year old male and female participants.
Continuous Radiolucent Line	24 months	X-rays are reviewed by an independent radiographic reviewer to determine if a 1 mm wide or greater, continuous radiolucent line around the entire bony border of the GLOBAL ICON Stemless Shoulder implant exists. Such a line may indicate the implant is loosening.
Kaplan Meier Survivorship	24 months	Kaplan Meier Survival Estimate is based upon the number of GLOBAL ICON implants remaining in the study and the number of GLOBAL ICON implants that have been revised (surgically removed from participants).
Device-related Serious Adverse Events	24 months	Adverse events are any untoward health issues that occur when compared to a participant's normal health baseline. Serious adverse events include health events that have led to death or a serious deterioration in health that resulted in life threatening illness/injury, permanent impairment of a body structure, required hospitalization or required medical intervention to prevent life threatening illness/injury or permanent impairment to a body structure or function.

Secondary Outcome Measures

Name	Time	Method
Mean Adjusted Constant-Murley Score at Baseline, 3, 12, 24, and 60 Months Post-operative	At Baseline (Day 0), 3, 12, 24, and 60 months	Constant-Murley Score was adjusted to reflect gender and age of participants. The Constant-Murley score was divided into four subscales, including pain (15 points maximum), activities of daily living (20 points maximum), ROM (40 points maximum), and strength (25 points maximum). The higher the score, the higher the quality of function (minimum 0, maximum 100). Adjustment may lead to scores above 100 depending on age of group analyzed. The range for the Adjusted Constant-Murley score in a male participant was 0-178.6; the range for the Adjusted Constant-Murley score in a female participant was 0-192.3. The calculations of the maximum Adjusted score assume a perfect score (100) in 100 year old male and female participants.
Mean Oxford Shoulder Score at Baseline, 3, 12, 24, and 60 Months Post-operative	At Baseline (Day 0), 3, 12, 24, and 60 months	The Oxford Shoulder Score (OSS) was a patient-based questionnaire used to assess shoulder pain after surgery. It consisted of 12 questionnaire items with 5 ordinal response options for each question. Each response was scored from 0 to 4 points (4 = best/least problems and 0=worst/unbearable pain). All item scores across 12 questions were summed to produce a scale of 0-48 (where a higher score reflected best/least problems).
Mean EuroQol-5 Dimension 5-Level (EQ-5D-5L) Scores by Dimensions at Baseline, 3, 12, 24, and 60 Months Post-operative	At Baseline (Day 0), 3, 12, 24, and 60 months	Mean EQ-5D-5L scores by dimensions at baseline, 3, 12, 24, and 60 months were reported. EQ-5D-5L consisted of the EQ-5D-5L descriptive system and the EQ Visual Analogue Scale (EQ-VAS). The EQ-5D-5L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The 5-item index score was transformed into a utility score between 0 (worst health state) and 1 (best health state). Higher score indicated good health. EQ-VAS self-rating records the respondent's own assessment of his/her overall health status at time of completion, on a scale of 0 (worst health you can imagine) to 100 (best health you can imagine). Positive change in score indicated improvement.
Mean Visual Analog Scale (EQ-VAS) Score at Baseline, 3, 12, 24, and 60 Months Post-operative	At Baseline (Day 0), 3, 12, 24, and 60 months	EQ-5D-5L consisted of the EQ-5D-5L descriptive system and the EQ-VAS. EQ-VAS self-rating records the respondent's own assessment of his/her overall health status at time of completion, on a scale of 0 (worst health you can imagine) to 100 (best health you can imagine). Positive change in score indicated improvement.
Number of Participants With Radiographic Evidence of Aseptic Loosening of the Global Icon Stemless Humeral Component Immediate Post-operative and 3, 12, 24, and 60 Months Post-operative	Immediate post operative (0-10 Days), at 3, 12, 24, and 60 months	Number of participants with radiographic evidence of aseptic loosening of the global icon stemless humeral component immediate post-operative and 3, 12, 24 and 60 months post-operative were reported. Aseptic Loosening was evaluated using all available imaging. Progressing radiolucencies and/or stress shielding indicated aseptic loosening.
