Table 3 4 female specimens, statistical analysis results were obtained by measuring the anatomical index distance of anterior circumflex brachial artery of proximal acromion of left and right shoulder humeral, superior circumflex anterior circumflex brachial artery of proximal margin of humeral humeral, superior circumflex anterior circumflex brachial artery of humeral head, superior margin of axillary nerve of inferior margin of humeral shoulder, superior margin of axillary nerve of humeral head
From: Digital analysis of external fixation area of proximal humerus fractures in elderly patients
Specimen number | Distance from the inferior border of the acromion to the superior border of the anterior rotator humeral artery (cm) | Distance from the apex of the humeral head to the superior border of the anterior rotator humeral artery (cm) | Distance from the inferior border of the acromion to the superior border of the axillary nerve (cm) | Distance from the apex of the humeral head to the superior border of the axillary nerve (cm) | ||||
