Intrapelvic Displacement of a Trial Femoral Head During Total Hip Arthroplasty and a Method to Retrieve It

Abstract 

We describe a technique to retrieve a dislodged femoral trial during total hip arthroplasty. During a revision total hip arthroplasty performed through a direct lateral approach, the femoral trial head was dislodged deep into the pelvis, superior and anterior to the hip joint and behind the anterior pelvic rim. This was retrieved via a posterior approach through the same incision by manipulating the trial head through the pelvis from the anterior to posterior direction. To our knowledge, this technique has not been described previously.
