Exactech Humeral Reconstruction Prosthesis of Shoulder Arthroplasty PMCF (HRP)

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to collect and evaluate long-term clinical outcomes data in order to better understand the safety and performance of the Equinoxe Humeral Reconstruction Prosthesis in shoulder arthroplasty over time. This study will follow subjects for a period of up to 10 years post-surgery.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| SST-12 | Shoulder Simple Test (SST) - 12 questions with yes/no responses that measure shoulder pain and function from a patient's perspective - 12 yes corresponds to 100% | Through study completion, an average of 1 per year | 
| SPADI | Shoulder Pain and Disability Index (SPADI) -13 questions assessing about pain scale (5 questions) and disability scale (8 questions) where 0 indicates no pain/no difficulty and 10 indicates worst pain imaginable/so difficult it requires help while performin these activities | Through study completion, an average of 1 per year | 
| Constant | Constant Shoulder Score - 100 points scale about pain, Activities of daily living, Strength test, and Range of Motions questions about shoulder where 100 % corresponds to the highest pain | Through study completion, an average of 1 per year | 
| ASES | American Shoulder and Elbow Surgeons Score (ASES) - 100 points scale about shoulder pain and performance evaluation in activities of daily living where 100 indicates the best shoulder condition | Through study completion, an average of 1 per year | 
| UCLA | University of California Los Angeles Shoulder Score (UCLA) - 5 Items score which combines both physician (3 items) and patient assessment (2 items) whith a total range from 0-35 where 0 indicates worse shoulder function and 35 better shoulder function outcomes | Through study completion, an average of 1 per year | 
| TESS | Toronto Extremity Salvage Score (TESS) - Patient functional assessment following for surgery for musculoskeletal tumors (Humeral Reconstruction Stem only) - 100-point score where higher score indicates a better outcome | Through study completion, an average of 1 per year | 
| MSTS | Musculoskeletal Tumor Society (MSTS) - 30 points [6 times (range 0-5)], simple measure of the upper extremity function (Humeral Reconstruction Stem only) - The maximum corresponds to the best score | Through study completion, an average of 1 per year |
