Ultrasonographic localization of a displaced screw in the carpal canal - Acase report

We present a case of a 65-year-old patient with a surgically treated distal radius fracture. At 5-month follow-up, conventional radiography revealed b reakage of the plate and a screw displaced into the volar soft tissue. Preo perative ultrasonography including dynamic assessment of the tendons showed the screw intratendinously as a hyperechogenic structure with repetitive e choes. This unusual localization was proven by surgery. Dynamic ultrasonogr aphy played an important diagnostic role in the localization of the loosene d and displaced osteosynthetic material.
