The use of a new augmented glenoid component has the advantages of preserving glenoid bone stock while restoring the alignment of the glenohumeral joint in anatomic total shoulder arthroplasty with severe posterior bone loss. We present the preoperative planning and surgical technique along with the early clinical and radiographic results of the first 24 cases using the DePuy Johnson and Johnson StepTech Anchor Peg Glenoid. Early results with a minimum of 6-month follow-up demonstrate excellent seating and clinical results with average active elevation of 162 degrees and postoperative PENN score of 84. Postoperative computed tomography analysis demonstrated excellent correction (mean 16.7 degrees) of glenoid version with minimal loss (mean 0.45 mm) of the premorbid joint line.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
