  14. where is the CR and angle of the foot for an oblique foot medial rotation
    • base of third metatarsal
    • and 30-40 degree medial rotation of the foot (inwards)
  15. what is a common trauma site for the foot
    base of the fifth metatarsal

    • 14 phalanges
    • 7 tarsals
    • 5 metatarsals
  17. what is the joint that articulates with the base of every toe
    metatarsophalangeal
  18. where are sesamoid bones usually found on the foot
    on the plantar surface at the head of the first metatarsal
  19. what is the largest and strongest bone of the foot
    calcaneus
  20. the sustentaculum tali is found on the
    calcaneus
  21. where is a common site for bone spurs
    the tuberosity on the bottom of the calcaneus
  22. the articular facets making up the tibial plateau slopes posteriorly at:
    10-20 degrees
  23. another term for the patellar surface of the distal femur is
    intercondylar sulcus
  24. the knee joint is classified as a what joint
    bicondylar
  25. where is the CR for a mediolateral projection of the foot
    CR to medial cuneiform
  26. which lateral rotation is best for a lateral view of the foot
    mediolateral
  27. where would we CR be for an ap toes of the second phalanx
    cr on long axis of the toe and CR at MTP joint of 2nd toe
  28. the oblique positioning of what toes is need for external rotation (lateral rotation)
    4 and 5 digit
  29. what digits require medial rotation for an oblique of the toe
    digits 1 2 3
  30. where is the CR for a lateral toe of the first digit
    IP joint
  31. where is the CR on a lateral position of the toes for digits 2-5
    PIP joint
  32. An ap projection of the toes requires all toes in view?
    yes but collimate to digit in question or depends on hospital policy
  33. where is the CR and position of the toes when doing oblique position
    what is the angle of tube
    • the CR is perpendicular to the to mtp joint
    • no angle on tube
    • toes are positioned on a medial or external rotation depending on which toe
  34. when taking an xray of the calcaneus where is the CR and angulation of the tube
    CR is at the base of the third metatarsal to emerge posterior malleoli(lateral) and the cr is angled 40 degrees cephalad
  35. what are the routine positions for the calcaneus
    • plantodorsal
    • lateral
  36. where is the cr for a lateral calcaneus (mediolateral projection)
    1 inch inferior to medial malleolus
  37. how do we know the patients foot is in a true lateral
    when the lateral malleolus about cm posterior to the medial malleolus
  38. What is the kv and cr for an ankle
    what should we not ask the patient to do in the position
    • 60 kv and + or - 5 kv
    • cr mid ankle include up metatarsals and some of the distal tib and fib
    • do not force dorsiflexion (keep foot in natural position and ensure no rotation
  39. What is the degree of angulation of the ankle in ap mortise
    what is parallel to the IR
    15-20 degrees until intermelleolar line is parallel to IR
  40. what is the rotation and degree of angulation in a oblique position of the ankle
    • internal rotation
    • and 45 degree oblique
  41. what is the position of the feet when doing a tib fib ap
    dorsiflexed 90 degrees if possible
  42. how do we know or ensure that the tibia and fibula are in a true lateral position
    the patella plane should be perpendicular to to the IR
  43. what is the the kv range and mas for clacaneus
    70 @ 16

    the lateral portion
  48. where is the CR for a mediolateral projection of the foot
    cr perpendicular to medial cuneiform
  49. what is the routine protocol for a tib and fib
