Article Title: Failure of Screw/Shell Interface in the Trident II Acetabular System in Total Hip Arthroplasty

doi: 10.1016/j.artd.2022.07.010

Figure Lengend Snippet: Postoperative anterior-posterior (a) and frog-leg (b) radiographs of the right hip after revision from a failed cephalomedullary nail to total hip arthroplasty. Of note, the failed acetabular screw could not be visualized on these views because orthogonal views of the acetabular cup were not obtained.

Figure Lengend Snippet: Two-week postoperative anterior-posterior (a) and cross-table lateral (b) radiographs of the right hip after revision from a failed cephalomedullary nail to total hip arthroplasty. On the cross-table lateral view, there is evidence of failure in 1 of the acetabular screws (red box); (c) magnified image.

Figure Lengend Snippet: Four-month postoperative anterior-posterior (a) and cross-table lateral (b) radiographs of the right hip. There has been no interval change in the position of the failed acetabular screw (c) seen previously at postoperative week 2 ( Fig. 3 ).

Figure Lengend Snippet: Preoperative anterior-posterior radiograph (a) demonstrating bilateral hip osteoarthritis, with the right hip showing more severe cartilage loss and subchondral sclerosis than the right hip. Intraoperative anterior-posterior radiograph (b) of the left hip with acetabular cup and retractors in place with failure of the acetabular screw (red arrow).

Figure Lengend Snippet: Schematic of the ideal angle to image acetabular screws and detect potential failure. The x-ray tube (black camera) and detector should be aligned tangential to the acetabular cup surface at the site of the screw. An additional orthogonal view should be acquired.

Figure Lengend Snippet: Rendering of the Stryker Trident II Acetabular System demonstrating the solid core screw hole profile. The recessed screw holes and low-profile hex screws enable up to 37 degrees of screw angulation and minimize the risk of interference with the liner bearing. However, the lower profile design may also contribute to the acetabular screw failure .
