Custom Glenoid Implant in Total Shoulder Arthroplasty: Case Report of Two Patients

Glenohumeral arthritis is typically treated with shoulder arthroplasty, however in younger patients with complex glenoid pathology this can become more challenging. Considerations surrounding surgical management strive to provide a functional, stable shoulder, while maintaining options for revision in the future. Custom glenoid implants have emerged as a promising option for patients in this challenging population, however there is a lack of literature surrounding their use for addressing glenoid bone loss for anatomic total shoulder arthroplasty. This case report highlights the course of treatment for 2 patients with severe glenoid bone deficiency and debilitating shoulder pain. A custom glenoid implant was used after careful consideration and review of available options. The use of a convertible custom glenoid implant for these patients allowed for improved function and decreased pain, while preserving options for treatment in the future.
