Q. Which of these feature on pelvis radiograph can give certain idea about flexion deformity of lower limb of one side?
a. Lesser trochanter
b. Obturator foramen
c. Diameter of head of femur
d. Distance of centre of head of femur and greater trochanter
e. Distance from greater trochanter to actabulum edge
Answer -
b
The comparison of bilateral obturator foramen can give some idea of long standing flexion deformity on one side, as both obturtor foramen won't be identical as that of affected side will appear smaller.
Lesser trochanter is helpful sometimes to ascertain rotation and not flexion usually following trauma.
