Operative and radiographic acetabular component orientation in total hip replacement: Influence of pelvic orientation and surgical positioning technique

Abstract: Orthopaedic surgeons often experience a mismatch between perceived intra-operative and radiographic acetabular cup orientation. This research aimed to assess the impact of pelvic orientation and surgical positioning technique on operative and radiographic cup orientation. Radiographic orientations for two surgical approaches were computationally simulated: a mechanical alignment guide and a transverse acetabular ligament approach, both in combination with different pelvic orientations. Positional errors were d… Show more

“…For patients with THA, the pelvis is the carrier of acetabular prosthesis, which also rotates along with the rotation of pelvis. Therefore, the situation of spine-pelvis-hip of patients with THA needs to be paid attention to, so as to avoid joint dislocation and reduce the edge loading [7][8][9][10] . 1.…”
