Document Summary

Lecture 12. 3: msk imaging 4 the lower limb. Patient lies supine with both lower limbs with slight internal rotation -> allows minimal overlap b/w trochanters and head of femur. Examines: pelvic ring, obturator foramina, sacroiliac joints, symphysis pubis, acetabula, proximal femurs. Clinically: high diagnostic yield in severe injury the lines will be very apparent in the x-ray. Pelvic bone develops as 3 separate bones: ilium, ischium, pubis -> meet at triradiate cartilage in acetabulum. Seen as dark spot within acetabulum of immature skeleton (very evident in 9month old: can also see that the femur hasn"t fully developed. 11 month old femoral heads are getting bigger but aren"t fully developed. Older child ilium, ischium and pubis on both sides are almost fully connected both femoral heads almost completely ossified greater trochanters developed to a point that make them look more similar to an adult. Ilium, ischium and pubis - fusion b/w 7-9 years old: replacement of triradiate cartilage 20-25 years old.
