5. Pearls/Pitfalls

a. There are several tricks that can be used to ensure appropriate trajectory of iliac crest pins:

i. Aim towards the contralateral greater trochanter

ii: Place a second pin resting along the inner table of the pelvis to help demarcate the slope of the iliac crest.

iii: Dissect soft tissues off the inner and outer table. Place thumb and index finger around the crest.  Aim the pin in that trajectory to ensure it is staying within the narrow corridor of bone.
