The Difference Between A Sprain And A Broken Foot
The patient remained in the supine position for the oblique projections of the ankle. His foot was placed into a 45 degree angle and we ensured that it remained in the center and aligned with the long axis of the image cassette. The patient was asked to keep his toes pointed up while maintaining the rotation without hurting himself. The central ray was placed perpendicular toward the midpoint of the malleolus for both projections; one rotated internally and the other with an external rotation. In the radiographs you could see the tibia, fibula, talus, medial and lateral malleolus, and calcaneus. The tibiofibular joint and tibiotalar joint were seen open and the trabecular patterns were well demonstrated.
The last image we had to take for the ankle was a mediolateral projection. The patients leg was rolled into a 90 degree rotation and the central ray was positioned to the base of the third metatarsal. The radiograph showed the distal portion of the tibia and fibula along with the calcaneus, talus, navicular, cuboid and tuberosity of the fifth metatarsal. The fibula was superimposed on the posterior half of the tibia and tibiotalar joint was well …show more content…
The angulation was removed off of the tube and the central ray was directed to the base of the third metatarsal. The entire foot was visualized to include all of the phalanges and metatarsals also the lateral cuneiform, cuboid, navicular, talus and calcaneus were seen. The base of the second to fifth metatarsals were superimposed with the tarsals and proximal metatarsal shafts were free of any superimpositions. Then the foot was rotated 30 degrees laterally and the central ray was kept in the same position. In the lateral radiograph the navicular was well pictured along with the space between the first and second metatarsals and
