Question

What is the difference between Lauenstein (Frog leg) and cross-table lateral views of the hip?

A) Different patient positioning and leg placement
B) Varied exposure factors and collimation
C) Distinct central ray angles and tube height

Answer 1

The difference between Lauenstein (Frog leg) and cross-table lateral views of the hip lies in the patient positioning and leg placement.

Step-by-step explanation:

The difference between Lauenstein (Frog leg) and cross-table lateral views of the hip lies in the patient positioning and leg placement. In the Lauenstein view, the patient is lying supine with one leg abducted and externally rotated, while in the cross-table lateral view, the patient is lying on their unaffected side with the affected leg hanging off the edge of the table. Both views allow for different visualization of the hip joint and surrounding structures.
