![]() ![]() The patient can remain supine with an image receptor placed vertically adjacent to the lateral aspect of the upright foot the X-ray beam is directed horizontally, centered 2.5 cm inferior to the prominence of the medial malleolus of the distal tibia. In trauma, it may not be possible to position the patient as above, in these cases the same principles can be applied with a modified horizontal beam view. If the patient cannot correct this position, it can be aided with a small wedge sponge. To adjust this, check the heel is not raised too far, or alternately, the toes. To adjust this, either lower the knee to better match the ankle or place the ankle on a small sponge to better match the knee.Īnterior-posterior malalignment of the talar domes is due to over- or under-rotation of the foot. Superior-inferior malalignment of the superior aspect of the talus is resultant of the tibia not lying parallel to the image receptor. The joint space between the distal tibia and the talus is open and uniform. The talar domes are superimposed allowing for adequate inspection of the superior articular surface of the talus. The calcaneus is in profile with the talonavicular joint open the distal fibula is superimposed by the posterior portion of the distal tibia, the t arsal sinus should appear open. inferior to the skin margins of the plantar aspect of the foot.Featuring: Fracture shaft of fibula bone ( leg bone ) Fracture shaft of fibula bone ( leg bone ). anteriorly from the hindfoot to the extent of the skin margins of the most posterior portion of the calcaneus Digital medical illustration: Lateral (side) x-ray view (orthogonal) of human foot and ankle.2.5 cm inferior to the prominence of the medial malleolus of the distal tibia. ![]()
