Abstract

Complex glenoid bone deformities present the treating surgeon with a complex reconstructive challenge. Although glenoid bone loss can be encountered in the primary setting (degenerative, congenital, post-traumatic), severe glenoid bone loss is encountered in most revision total shoulder arthroplasties. Severe glenoid bone loss is treated with various techniques including hemiarthroplasty, eccentric reaming, and glenoid reconstruction with bone autografts and allografts. Despite encouraging short- to mid-term results reported with these reconstruction techniques, the clinical and radiographic outcomes remain inconsistent and the high number of complications is a concern. To overcome this problem, more recently augmented components and patient specific implants were introduced. Using the computer-aided design and computer-aided manufacturing technology patient-specific implants have been created to reconstruct the glenoid vault in cases of severe glenoid bone loss. In this article we describe a patient specific glenoid implant, its indication, technical aspects and surgical technique, based on the author's experience as well as a review of the current literature on custom glenoid implants.
