Skeletal trauma

Skeletal trauma

Musculoskeletal trauma is best imaged by an initial plain radiograph. All skeletal radiographs should be taken from two di ff erent angles, usually at right angles to each other. This is important in trauma because a fracture or dislocation may not be visible on a single view ( Figure 8.18 ). Occasionally , specific locations such as the scaphoid, more than two views are routinely performed. If this fails to make a clear diagnosis, or if there is suspicion of soft-tissue injuries, then cross-sectional ted. studies are indica Increasingly in the assessment of spinal trauma, CT is replacing radiographs as the first-line investigation for two main reasons: the first is that the sensitivity of CT is superior, , enabling treatment to com the second is that it is quicker mence sooner.
