A thorough understanding of normal and degenerative shoulder anatomy is necessary, as …

Glenoid morphology has an important impact on outcomes and complication rates after
shoulder arthroplasty for primary glenohumeral arthritis. The B2 glenoid, or a biconcave …

Background: There have been many clinical reports of patch graft surgery for irreparable
rotator cuff tears. However, the retear rate of the patch graft is relatively high because of the …

Background: Patients with irreparable rotator cuff tears have a defect of the superior capsule,

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

Background: It has been suggested that glenoid component retroversion and eccentric
loading are an important mechanism leading to glenoid component loosening, but little …

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 …
