Managing glenoid bone loss in total shoulder arthroplasty: Role of augmented patient-specific implants

Total shoulder arthroplasty has been shown to generate good to excellent results for patients with osteoarthritis and a functioning rotator cuff. However, a major complication after primary total shoulder arthroplasty is loosening of the glenoid component, which has been shown to be commonly associated with glenoid retroversion. This article highlights the importance of correcting the glenoid version and reviews various techniques, such as eccentric reaming, posterior bone grafting, reverse shoulder arthroplasty, and augmented glenoid implantation to address glenoid retroversion in the setting of total shoulder arthroplasty.
