Abstract
An acetabular shell insertion tool with an anti-rotation feature is provided. The insertion tool attaches to an acetabular shell including a center hole having an internal threading and an anti-rotation recess disposed around the center hole and having a predetermined shape. The insertion tool includes an outer shaft and an inner shaft disposed within the outer shaft. The outer shaft has an anti-rotation projection shaped to be received in the anti-rotation recess of the acetabular shell so as to prevent rotation of the outer shaft relative to the acetabular shell, thereby preventing the insertion tool from disengaging from the shell. The inner shaft has a threaded tip adapted to be threaded into the internal threading of the center hole to lock the insertion tool to the acetabular shell.
