Lesser tuberosity is more reliable than bicipital groove when determining orientation of humeral head in primary shoulder arthroplasty

Abstract

The objective of the study was to provide statistical evaluation of position of bone landmarks of proximal humerus (lesser tuberosity, greater tuberosisty, sulcus bicipitalis, crest of greater tuberosity) in relation to transepicondylar line and find out which one is the most suitable for setup of the head retroversion in case of humeral head destruction
