The hamate bone, one of the carpal (wrist) bones, has a large uncinate process protruding from the palm side. In sports such as golf and tennis, the hamate bone can break if is subjected to a high external force, such as from the handle of a racquet or club. At our hospital we take X-ray images of the hamate bone from two directions: an axial image through the carpal tunnel and an image at the base of the hamate hook (conventional method). While the conventional method makes it easy to create images of the base of the hamate hook, the patient may suffer pain during image-taking because the hamate bone is pulled to cause radial flexion. We therefore investigated a method of imaging that would create three-dimensional computed tomography (3DCT) images of the base of the hamate hook in which the patient would only have to only rotate the wrist externally and elevate the fore-arm without any radial flexion. Our results suggest that it is possible to obtain images of the base of the hamate hook as clear as those acquired using the conventional method with the patient in a comfortable and painless position taking images at an external rotation angle of 50.3° and a forearm elevation angle of 20.3°.

A study of a method of taking X-rays of the shoulder joint axis when the upper arm is fixed and cannot be rotated. When the shoulder joint has suffered damage, rotating the arm can be very painful, and obtaining accurate images of the axis is frequently difficult. For this reason, at this hospital, the Stockinette-Velpeau procedure is used on patients who cannot rotate their arms to have X-rays taken. In this procedure, the patient bends backwards at a 40-degree angle, and an X-ray of the shoulder joint axis is taken from directly below the joint. Using this method, even if the upper arm is hanging down, information regarding the direction of the axis can be obtained. However, maintaining this body position is difficult and requires assistance. The patient may also experience pain. For this reason, a new method was sought of X-raying the axis from a body position that is easier on the patient and by which diagnostic information on the axis direction can be obtained from patients who cannot rotate their upper arms. The result of seeking a new method was an X-ray that can be taken diagonally at a 25-degree angle relative to the shoulder joint socket. This X-ray method requires no rotation of the axis and provides the closest view of the axis. This new method suggests a way to X-ray the axis that is easy on patients even when the shoulder joint is damaged.

A hand hygiene behavior questionnaire and environmental survey were conducted regarding the mobile X-ray system used in the emergency room. As a result, among a total of 22 radiological technologists at this hospital who replied to the questionnaire, 18 wore disposable gloves when performing X-ray imaging using the mobile system. Among those 18, 11 were found to touch computed radiology (CR) consoles and HIS/RIS terminals while still wearing the gloves, thus creating the potential for spreading pathogens to other medical equipment and systems. According to the results of an environmental survey of the emergency imaging preparation room, the highest levels of bacteria were detected on CR consoles and HIS/RIS terminals. A possible reason for this is that these locations are not wiped down and cleaned as a part of routine cleaning and disinfection protocols, thus demonstrating the importance of cleaning and disinfection. Hand hygiene by medical personnel and appropriate cleaning and disinfecting of the working environment are important for preventing the spread of nosocomial infections. Radiological technologists are also required to take effective measures against infections in consideration of the high frequency of contact with both infected patients and patients susceptible to infections.
