GROSS ANATOMY

Detailed explanation-1: -The clavicle AP view is a standard projection part of the clavicle series. The projection demonstrates the shoulder in its natural anatomical position allowing for adequate radiographic examination of the entire clavicle.

Detailed explanation-2: -An anteroposterior (AP) view and a 45° cephalic tilt view are standard for the initial radiographic evaluation. These will delineate fracture displacement, as well as fractures to the medial clavicle and first rib. (The proximal humerus and scapula should be looked at for possible associated fractures.)

Detailed explanation-3: -The routine radiographic examination of the clavicle (Fig. 8.8) consists of a straight AP and a tangential AP projection with the central beam angled rostrally and tangent to the anterior chest wall to project the clavicle off the ribs as much as possible.

Detailed explanation-4: -Evaluation of the distal third of the clavicle and the acromioclavicular joint (ACJ) is accomplished with two radiographs, an anteroposterior (AP) view in the plane of the thorax and an axillary lateral view (which has already been discussed in the section on glenohumeral joint radiographs).

Detailed explanation-5: -This projection straightens out the clavicle and projects most of it above the scapula and second and third rib. It can help to determine angulation of fractures and dislocation 1.
