The clavicle or collarbone is a long bone that serves as a strut between the shoulder blade and the sternum or breastbone. There are two clavicles, one on the left and one on the right. The clavicle is the only long bone in the body that lies horizontally. X-ray may be ordered to evaluate for various injuries and conditions, including: fractures (breaks), dislocations (joints that are pulled or pushed out of their normal position) to this region.
The most common X-ray views are poster anterior, anteroposterior, and lateral. In a poster anterior (PA) view, the x-ray source is positioned so that the x-ray beam enters through the posterior (back) and exits out of the anterior (front), where the beam is detected. To obtain this view, the patient stands facing a flat surface behind which is an x-ray detector. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect. AP is harder to read than PA x-rays and is therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. Lateral views are obtained in a similar fashion as the poster anterior views, except in the lateral view, the patient stands with both arms raised and the side of the chest pressed against a flat surface. The oblique view is projection taken with the central ray at an angle to any of the body planes. It is described by the angle of obliquity and the portion of the body the X-ray beam exits; right or left and posterior or anterior. Right or left as stated above indicates the portion of the body the X-ray beam exits. The axillary view is useful for detecting anterior or posterior dislocations that are not evident in the AP view. The knee skyline Laurin view is one of many different methods to obtain an axial projection of the patella. This projection is best suited to patients able to maintain a semi-recumbent position on the examination table.
An X-ray - AP&LAT Clavicle is an imaging test that uses small amounts of radiation to produce pictures of the organs, tissues, and bones of the body.
