Database Retrieval for the Comprehensive Shoulder

Study Overview
=================
Brief Summary
-----------------
This study is a retrieval of database information regarding survivorship of the Comprehensive Shoulder System family of products. The primary objective of the retrieval is to collect data that will contribute to the post market surveillance requirements for this product and will provide feedback to design engineers, support marketing efforts and publications, and answer potential questions form reimbursement agencies.

Detailed Description
-----------------
The Comprehensive Shoulder System has been cleared by the FDA via premarket notifications. No experimental or investigational surgical techniques or devices will be used in this study. All devices and products will be used in accordance with their instructions for use and/or approved labeling. The aim of the Comprehensive Shoulder System is to improve shoulder function and reduce pain. One site will be used for this database retrieval. The number of patients involved will depend upon the size of the Comprehensive database available at Acromion, LLC.

Official Title
-----------------

Osteoarthritis of the Shoulder, Avascular Necrosis, Rheumatoid Arthritis, Prior Failed Revision, Correction of Functional Deformity, Fracture of Proximal End of Humerus, Cuff Tear Arthropathy

Intervention / Treatment
-----------------
* Device: Biomet Comprehensive Shoulder System


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Must have one of the following indications: Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis. Rheumatoid arthritis Revision where other devices or treatments have failed. Correction of functional deformity. Fractures of the proximal humerus, where other methods of treatment are deemed inadequate. Difficult clinical management problems, including cuff arthropathy, where other methods of treatment may not be suitable or may be inadequate. Need to obtain pain relief and improve function Ability and willingness of the patient to follow instructions, including control of weight and activity level A good nutritional state of the patient The patient must have reached full skeletal maturity Exclusion Criteria: Absolute contraindications include infection, sepsis, and osteomyelitis. Uncooperative patient or patient with neurologic disorders who is incapable or unwilling to follow directions. Osteoporosis. Metabolic disorders which may impair bone formation. Osteomalacia.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Biomet Comprehensive Shoulder System<br>Subjects in need of a total shoulder arthroplasty who met the inclusion/exclusion criteria and received the Comprehensive Shoulder System. | Device: Biomet Comprehensive Shoulder System<br>* Total shoulder system designed to provide intraoperative flexibility for surgeons with unmatched humeral stem options, and infinite humeral head offset possibilities while meeting the growing demand for ease of glenoid preparation through a streamlined, low-profile, cannulated instrument platform<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Implant survivorship is assessed counting the number of implant revisions | Implant survivorship will be documented by assessing the number of implant revisions occurring throughout the course of the study. | 10 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Constant Shoulder Score | The Constant-Murley Shoulder Score is a scoring method used by clinicians to assess function of the shoulder. The standard score is on a scale of 0 to 100, with 0 being no shoulder function and 100 being excellent function. | 10 years | 
| Clinical Safety | Clinical safety is assessed through documentation of complications occurring during the course of the study. | 10 years | 
| Clinical Safety - Device Related | Clinical safety is assessed through documentation of device-related events occurring during the course of the study. | 10 years |
