Citation, DOI & article dataCitation: Shetty, A., Murphy, A. Humerus (AP view). Reference article, Radiopaedia.org. (accessed on 08 Sep 2022) https://doi.org/10.53347/rID-35282 The AP view of the humerus is part of the humerus series and is usually taken in a standing position. However, it can also be obtained in a supine position. The projection demonstrates the humerus in its natural anatomical position allowing for adequate radiographic examination of the entire humerus and its respected articulations. On this page:Humerus views are often done to exclude large humeral shaft fractures or suspected symptomatic metastatic lesions 1. If an occult fracture is suspected at either the proximal or distal end, it is best to do a separate elbow or shoulder series.
The humerus is positioned AP, evidenced by the medial and lateral epicondyles seen in profile and the greater tuberosity being seen on the lateral aspect of the humerus. The shaft is abducted away from the patient's body, minimizing superimposition It is best to show the patient how you want their arm to rest for the projection. Often, you will have to rotate the light beam diaphragm to be aligned with the long axis of the humerus.

What structure is found on the lateral aspect of the proximal end of the humerus?The greater tuberosity it is located lateral to the head at the proximal end. The lesser tuberosity is located inferior to the head, on the anterior part of the humerus, Its very prominent and palpable.
What structure is in profile on the medial surface of the proximal humerus when positioning a lateral humerus?Lesser tubercle is superimposed over humeral head. Internal rotation is evident by lesser tubercle visualized in full profile on the medial aspect of humerus.
What is the structure of the humerus on the proximal epiphysis of the humerus?The proximal humerus is composed of four distinct anatomic segments: 1) the shaft of the humerus, 2) the greater tuberosity, 3) the lesser tuberosity, and 4) the articular or head segment. These segments correspond to the four ossification centers of the proximal humerus.
