Finger series (pediatric)

Last revised by Andrew Murphy on 23 Mar 2023

The f​inger series for pediatrics often consist of a posteroanterior and lateral view only in order to minimize radiation dose to the patient. Depending on the department and clinical indication, an additional oblique view may also be done.

  • trauma with suspected fracture

  • suspected dislocation

  • foreign body detection

Patients should remove any jewelry on the finger(s) of interest. 

The use of gonadal and fetal shielding has been deemed as non-beneficial to patients' health in current evidences 1-3 and may or may not be useful for pediatric extremity imaging. Placing gonadal shielding can increase the examination time and may cause the child more stress.

The major difficulty in pediatric hand radiography relates to:

To overcome this, a variety of techniques can be used 4:

  • distract the patient with toys, games and/or conversation

  • using the swaddling technique; wrap the child in a blanket to promote comfort and sleep

  • have the child sit on the parent's lap to ensure they are comfortable

Children will find it difficult to keep their finger still; particularly if the limb is injured. One option is to have a parent or radiographer hold the child's hand in place; however, the parent's hand may appear on the radiograph and obscure the child's anatomy. Placing radiolucent items such as a clear clipboard on top of the child's hand can be useful for keeping the child's hand flat and still for the posteroanterior view. However, placing items on top of the child's hand should be used only if it will not injure the child further.
