TSA Techniques in Glenohumeral OA

"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."

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.

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.
