AO/ASIF Femoral Distractor

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
