Question

For an AP oblique projection of the mortise joint the radiographer should angle the leg and foot __________ medially and the foot should be in _________

Answer 1

For an AP oblique projection of the mortise joint, the radiographer should position the leg and foot 15 to 20 degrees medially with the foot dorsiflexed for proper imaging.

Step-by-step explanation:

For an AP oblique projection of the mortise joint, the radiographer should angle the leg and foot 15 to 20 degrees medially, and the foot should be in a dorsiflexed position. Dorsiflexion involves decreasing the angle between the dorsum of the foot and the leg, which means pulling the toes up towards the shin. The positioning is important to ensure an accurate representation of the mortise joint for diagnostic purposes. The alignment based on the upright anatomical position ensures that medial rotation and dorsiflexion are correctly achieved. This oblique angle allows for clear imaging of the joint space without overlay of the tibia and fibula.
