MRI of seemingly isolated greater trochanteric fractures.

OBJECTIVE: The objective of this article is to show that greater trochanteric fractures commonly perceived on routine radiographs as isolated are often neither isolated nor minor and that MR images can serve as a basis for more informed treatment by revealing the actual extent of such fractures in acute posttraumatic settings.
CONCLUSION: A pitfall in diagnosing seemingly isolated greater trochanteric fractures on routinely used imaging techniques lies in the fact that the injuries usually involve a large anatomic area. In our experience, MRI more accurately defines the true geographic extent of greater trochanteric fractures sustained through acute trauma than do radiography and bone scintigraphy and thus could provide a more reliable basis for anticipating complications and for planning appropriate treatment.
