The hands are one of the most important elements of the human body, since they are the tools we use the most to function in our environment. Hence, in case we suffer any injury or pathology In them, surely The doctor will ask us to do a hand X-ray.
It should be noted that X-rays are a very common imaging study. This is a painless process which will simply allow specialists to observe how bones, their density and joints are doing.
Indeed, when there is a trauma or blow in some part of the hands, radiologists will focus on doing the study in that area. However, if it is a question of analyzing the progress of other pathologies such as osteoporosis and arthritis, this professional must position these organs in such a way that each of their parts is evident.
Importance and scope of hand radiography
Since the hands are such powerful tools, X-rays are the most reliable tests for evaluating your health in a quick and practical way. With radiographs, they are obtained images of all internal structures of every part of the body, as X-ray beams pass through bone materials.
However, depending on the amount of detail required in the hand x-ray, the specialist will apply different contrasts that make it possible to interpret the images. In the case of the hand, this need to apply Chemicals Additional parts such as iodine or barium are viable, since this organ is made up of 27 bone pieces, some of them very small that can be difficult to observe.
Although it seems that we only have five main finger bones, they are actually divided into three Phalanges that make it possible to articulate and move. Las Phalanges Distals are the bones that are at the end of the hand, followed by Medials And Proximal. In addition, we have the metacarpals (one for each finger) that make up the palm of the hand, as well as 7 units that make up the Carpians Or the call Wrist.

In this case, other imaging studies may also be indicated, such as magnetic resonance imaging, ultrasound or tomography.
