- indications:
    - allows unobstructed view of articular surface of acetabulum;
- technique:
    - proximal bolt is inserted in the iliac wing in its superior portion, just distal to thickened crest;
          - proximal bolt must pass through portion of ilium in continuity w/ sacrum (or frx proximal to this point must be stabilized) prior to application of a distraction force;
    - distal bolt is positioned through both cortices of femur distal to the greater trochanter
    - distraction of the femur distally permits controlled, sustained visualization of the superior acetabular articular surface;
    - internal and external rotation of the femoral shaft allows improved visualization of the anterior and posterior aspects of acetabular articular surfaces
