[A combination of conventional single contrast arthrography with arthro-CT of the shoulder--an evaluation of 78 cases].
For the diagnosis of traumatic shoulder lesions, 78 patients have been examined by conventional single contrast arthrography with subsequent CT. For 26 patients, it was possible to compare the radiological diagnosis with the arthroscopic or surgical findings. The combination of both diagnostic methods provided a high sensitivity (94%) and specificity (100%) for lesions of the ventral or dorsal limbus. Ruptures of the rotator cuff showed a sensitivity of 60% and a specificity of 89%. An unsatisfying sensitivity (60%) with high specificity (95.6%) was observed in the diagnosis of the ventral capsula. A retrospective screening of the roentgenography showed a good detectable leak of contrast medium, which was misinterpreted as being an artefact. All in all, the combination of conventional arthrography in mono-contrast and CT in daily routine should be recommended the diagnosis of traumatic shoulder lesions since it is easy to use, is of low inconvenience for the patient, and provides a high level of information.
