“Approach to Glenoid Management in Shoulder Osteoarthritis (OA)”
The primary objective of this study is to determine the difference in disease specific quality of life outcome measures between patients diagnosed with osteoarthritis of the shoulder joint whom require a total shoulder arthroplasty (TSA) between the following study arms: 1)TSA using an augmented component compared with TSA using a standard component with eccentric reaming in patients or 2) TSA using an augmented component compared with posterior bone grafting.

Procedure - Eccentric Reaming
Pre-operative CT imaging and surgical planning software based on pre-operative CT scans will be used in each case to determine the degree of eccentric ("high side") anterior reaming to within < 10 degrees of neutral glenoid version.
Procedure - Augmented Glenoid Component Implantation
Patients will undergo standard glenoid preparation and implantation of a posteriorly augmented glenoid component. The degree of posterior augment will be based on pre-operative CT scan assessment and templating software with the goal of correcting glenoid retroversion to within 10 degrees of neutral version.
Procedure - Posterior Glenoid Bone Grafting
Patient will undergo a total shoulder arthroplasty as per standard technique. Glenoid version will be restored to within 10 degrees of neutral with a posterior glenoid bone graft. The bone graft will be harvested from the humeral head and fixed to the posterior glenoid with mini-fragment screws.
