The clavicle is an S-shaped bone that articulates laterally with the acromioma process of the scapula, medially with the manubrium of the clavicular notch to form the clavicular joint. An avulsion fracture is a disconnection of the clavicle bone caused by direct and indirect trauma in the position of the arm being cut off or pulled out (outstretched hand) because the trauma continues from the wrist to the clavicle. Radiography is an appropriate method to show abnormalities in the os calvicula. The aim is to show the anatomy of the clavicle bone and its abnormalities. This examination uses the Antero-Posterior projection. The X-ray aircraft used is GE with a capacity of 500 mA. The tape used is 30 cm x 40 cm. Processing film used is Computed Radiography.

Paranasal sinus radiography is an appropriate method for showing abnormalities in the paranasal sinuses and showing abnormalities in suspected Maxillary Sinusitis. The purpose of this examination is to determine the location and location of sinusitis by obtaining an optimal picture with radiographic examination of the paranasal sinuses. This research was conducted at the Radiology Installation of the University of North Sumatra-Medan Hospital. Using a general X-ray unit with an aircraft capacity of 1100 mA in February 2022 - May 2022, with a qualitative descriptive research type. To show the anatomical description and pathological abnormalities in the paranasal sinuses, especially maxillary sinuses, parietoacanthia (water's method) and lateral projections are used. The results of the examination showed that there was Sinusitis Maxillaris Sinistra and a suspected Sinusitis Ethmoidalis Sinistra.
