Abstract: A method for securing a stemless humeral includes positioning the stemless humeral anchoring component to the humerus such that a lateral anchoring wing extends in a direction of a lateral side of the humerus into a lateral region and two medial anchoring wings face a medial side of the humerus in a medial region. The lateral region has a lower bone density relative to the medial region. The stemless humeral anchoring component is positioned eccentrically such that the anchoring stud and the two medial anchoring wings are anchored in the medial region. The stemless humeral anchoring component is secured in resected proximal epiphyseal and metaphyseal portions of the humerus without reaching a diaphyseal portion of the humerus.
