Sheth MM, Morris BJ, Laughlin MS, et al. - Researchers assumed that total shoulder arthroplasty (TSA) performed for Walch type C dysplastic glenoids with standard glenoid components can reliably produce successful results at short to midterm follow-up. Researchers distinguished all individuals that had primary anatomic TSA conducted for osteoarthritis in a prospective shoulder arthroplasty registry collected from 2004 to the present time. Twenty-nine patients were included as inclusion criteria of a preoperative Walch type C dysplastic glenoid, treatment with TSA using standard (non-augmented) glenoid components, and a minimum of 2-years clinical follow-up. For anatomic shoulder arthroplasty, a matched cohort of 58 patients with a type A1 glenoid and a minimum of 2-years clinical follow-up served as the control group. In comparison with patients with type A1 glenoids, anatomic TSA reliably produced clinically significant improvements in pain and function and similar short to midterm outcomes in patients with Walch type C dysplastic glenoids. The outcomes of this research demonstrate that anatomic TSA with standard (non-augmented) glenoid components should remain an option in patients with Walch type C dysplastic glenoids despite emerging treatment options including augmented glenoid components and reverse total shoulder arthroplasty.
