# Tibia and Fibula ## Leg Projection ### AP Projection - supine; - Femoral condyles // to IR - Foot is Vertical (Dorsiflex) to IR ### Lateral Projection Mediolateral - supine; - turn toward the affected side RPO / LPO; - Patella I to IR; - Femoral condyles I to IR - Lateral side Place on IR ### Alternativemethod (can't turn) - CROSS-Table, horizontal CR; - IR placed b/n the legs & RP lateral side ### AP oblique Projection - Supine; - Leg Rotate 45° med / Laterally - medial - turn leg inward; - Rest the foot & ankle on 45° foam wedge ## Midshaft ### Medial Rotation - Proximal & distal tibiofibular jt. - maximum interosseous space b/n T & F ### Lateral Rotation: - Tibia superimpose fibula - ankle and knee Jt. ## Midshaft ### Lateral pros. - Tibia & fibula adjacent Jts ## Long Legs: CT - use 2 separate image - cover w/ lead the unexposed part **Fig. 6-127 AP tibia and fibula.** ## Lateral - Patella - Femoral condyles **Fig. 6-129 Lateral tibia and fibula.** **Fibula: 1cm Posterior than Tibia** **Fig. 6-131 AP oblique leg, medial rotation.** **Fig. 6-132 AP oblique leg, lateral rotation.** **Fig. 6-133 AP oblique leg, medial rotation, showing a fixation device.** **Fig. 6-134 AP oblique leg, lateral rotation, with a fixation device in place.**
