Normal variations in anatomy in the skeletally immature patient may be mistaken for fracture or injury due to the presence of secondary centers of ossification. Variations in imaging exist from patient to patient based on sex, age, and may even vary from one extremity to the other on the same patient. Despite differences in the appearance of the bony anatomy of the elbow there are certain landm...

Fractures of the distal radius can be complex injuries, often generating multiple fragments with distortion of the normal anatomy in all three dimensions. Superficial assessment of the injury on the standard PA and lateral radiographs often can result in incomplete recognition of the injury pattern and a misdirected approach to treatment. In addition, failure to recognize subtle radiographic fi...

With the development of computed tomography, ultrasonography and specialized scintigraphic techniques, conventional radiographic imaging of the abdomen has generally been relegated to a minor position in each of the three clinical entities under discussion in this series. On the other hand, one can make a good case for routinely obtaining radiographs of the abdomen in most patients with an acut...

OBJECTIVE To analyze intra and interobserver agreement of two radiographic methods for evaluation of posterolateral lumbar arthrodesis. METHODS Twenty patients undergoing instrumented posterolateral fusion were evaluated by anteroposterior and dynamic lateral radiographs in maximal flexion and extension. The images were evaluated initially by 6 orthopedic surgeons, and after 8 weeks, reassess...

The sensitivity of radiographic diagnosis of silicosis in an occupational medical care (primary examination) varied between 39% and 71%, and the specifity between 60% and 99%. This means that, if the prevalence of silicosis in dust exposed population is between 2% and 8%, 23% to 56% of silicosis cases are likely to be falsely diagnosed. The dependence of misdiagnosis of silicosis on the prevale...
