Single Center Post Approval Proximal Humerus Fixation With the Conventus Cage PH™ Device

Study Overview
=================
Brief Summary
-----------------
The Conventus CAGE™ PH (PH Cage) System Post-Approval Observational Data Collection Study (Study) is a single center, prospective, post-approval clinical study designed to collect device and procedure experience in everyday clinical practice.

Detailed Description
-----------------
The study is a prospective, non-randomized, post-market approval data collection study that is designed to collect device/procedure and outcome data on patients who have experienced proximal humerus bone fractures and received a PH Cage. Specifically, the study will provide: Patient outcome and performance data for the implant and implant procedure that that may be used to support scientific publications. Assurance of continued product safety and effectiveness.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: Conventus Cage PH device|The Conventus CAGE™ PH (PH Cage) is a permanent implant comprised of an expandable scaffold, made from nitinol and titanium, which is deployed into the medullary canal and provides a structure to which fractured bone fragments are attached using fragment screws.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Primary Performance Patient Assessment | Constant Murley Score (CMS) The Constant Murley Score is a combination of visual analog scales assessing pain, activities of daily living and assessments of range of motion and strength using a long-armed goniometer and isometer. The higher the score the better for the following sections of the CMS: A. Pain (0-15 points) (e.g.15=no pain, 2=high pain), B. Everyday activities-question 1 (0-2 points) (e.g. 2=best, 0=worst), questions 2 and 3(0-4 points) (the higher the score the better), question 4 (0-10 points) C. Movement- questions 1 and 2 (0-20 points) (e.g. the greater the range of motion performed, the more points assigned), questions 3 and 4 (0-10 points) (e.g. points assigned based on movements performed) D. Strength (0-25 points) Score is calculated from the highest score of three attempts, with each score corresponding to the force in pounds (max 25 points) The overall score is then calculated by combining all sections (A+B+C+D= 0-100 points) | Change from Baseline in Constant Murley Score at the 2 year post op |
