Bleeding in Primary Shoulder Arthroplasty

The aim of this investigation was to analyse “total blood loss” (TBL), “blood transfusion rate” (BT) and the “amount of transfused blood units” (BU) between the different primary shoulder arthroplasty (SA) types: reverse, anatomical and stemless. Only primary SA was included. Further goal was to identify risk factors for TBL, amount of BU and BT rate.
