Document Summary

Critique: a true ap position is achieved evidenced by, the lateral joint space is not open, the medial mortice is open, the tibiotalar joint is open and at the centre of collimation. Area covered: distal third of the tibia and fibula, proximal half of the metatarsals, lateral and medial malleoli, talus, soft tissues. Collimation: centre: the midpoint between the malleoli, shutter a: open to include thelateral skin margins, shutter b: open to include thedistal third of the tibia and fibula and the proximal half of the metatarsals. Notes: external rotation of the leg will show greater superimposition of the tibia and talus on the fibula. The effect of not achieving the lower leg in ap position. Internal rotation of the leg will show no superimposition of the talus on the fibula. Area covered: distal 1/3 of the fibula and tibia, lateral and medial malleoli, talus, proximal metatarsals, soft tissue and skin margins of the ankle.
