Abstract:
Total hip arthroplasty (THA) has been one of the most successful orthopaedic surgery in the last 50 years, with an excellent survival rate of more than 20 years. However, hip instability, impingement, dislocation, and liner wear remain common causes of THA failure and revision after THA. To minimize the risk of postoperative complications, abnormal spine-pelvic-hip mobility and its impact on THA outcomes have received increasing attention. According to the concept, the patient's pelvic mobility should be fully considered when making preoperative plans for THA. Individualized anteversion and inclination angles should be set according to the patient's sagittal balance and pelvic mobility to reduce the incidence of postoperative adverse events and prolong the life of the prosthesis. In the literature, recent studies have shown that patient aging, postural changes in daily life, high body mass index (BMI), and different surgical approaches and positions can impact spinopelvic mobility. Because changes in pelvic mobility translate into changes in acetabular orientation, excessive intraoperative or postoperative changes in pelvic mobility may result in poor intraoperative prosthesis orientation, postoperative impingement, dislocation, and accelerated liner wear, ultimately shortening the life of the prosthesis. Therefore, it is vital to evaluate and measure spinopelvic mobility preoperatively, investigate the factors that influence intraoperative pelvic mobility changes and the use of assisted positioning devices for accurate cup placement, and observe postoperative changes in pelvic mobility and the resulting adverse outcomes. This review takes the current literature on the spine-pelvic-hip interrelationship as a starting point and presents studies on the factors influencing spinopelvic mobility and the strategies for perioperative management of THA.
