The Use of a Custom Glenoid Component for the Treatment of Severe Glenoid Bone Loss in Reverse Total Shoulder Arthroplasty

Reverse total shoulder arthroplasty has been shown to be effective in reducing pain and improving pain and function in patients with rotator cuff arthropathy, as well as a variety of glenohumeral pathologies with associated rotator cuff deficiency. Severe glenoid bone loss is a surgical challenge that can prevent successful implantation of the glenoid component. We present the use of a custom glenoid component, fabricated using computed tomography 3-dimensional reconstructions and computer-aided design, to treat severe glenoid bone loss in the setting of reverse total shoulder arthroplasty. At early follow-up, we were able to provide pain relief and functional improvement using this novel technique.
