Changes in pelvic orientation after total hip arthroplasty : a prospective study with EOS™
Article dans une revue avec comité de lecture
JournalActa Orthopaedica Belgica
Changes in pelvic orientation after THA could alter the relationship between the femoral stem and the acetabular component and may be responsible of dislocation and implant degeneration. EOS™ technology allows three-dimensional analysis of the pelvis in functional position with low irradiation. The purpose of the study was to evaluate changes in pelvic orientation after THA in standing position with EOS™. In a prospective study, EOS™ was performed in standing position preoperatively and 3 months after computer assisted THA for primary hip osteoarthritis. Differences between pre- and postoperative pelvic parameters values were analyzed. 40 patients were included. Changes greater than 5° was noted in 12,5% of cases for pelvic incidence, 35% of cases for sacral slope and in 22,5% of cases for pelvic version. In conclusion, pelvic parameters could be modified after THA.
