Introduction Total Shoulder Arthroplasty (TSA) anatomical, reverse or both is an increasingly
popular procedure but the glenoid component is still a weak element, accounting for 30 …

Glenoid bone deficiency and eccentric posterior wear are difficult problems faced by
shoulder arthroplasty surgeons. Numerous options and techniques exist for addressing …

Background Glenoid component positioning is a key factor for success in total shoulder
arthroplasty. Three-dimensional (3D) measurements of glenoid retroversion, inclination, and …

Background: Glenoid component malposition for anatomic shoulder replacement may result
in complications. The purpose of this study was to define the efficacy of a new surgical …

Background: Preoperative computed tomography (CT) measurements of glenoid version
and inclination are recommended for planning glenoid implantation in shoulder arthroplasty …

Aims Patient-specific glenoid guides (PSGs) claim an improvement in accuracy and
reproducibility of the positioning of components in total shoulder arthroplasty (TSA). The …

Hypothesis and background The purpose of this study was to compare the accuracy of
patient-specific guides for total shoulder arthroplasty (TSA) with traditional instrumentation in …

BACKGROUND: Malposition of the glenoid component can result in premature component
loosening or instability. This study was designed to test the ability of an experienced …
