How Does THA Impingement Risk During Activities of Daily Living Change With Pelvic Tilt and Spinopelvic Mobility?

Description

The presentation begins with an introduction and a disclaimer regarding disclosures related to Smith and Nephew. The speaker discusses the primary causes of total hip replacement, focusing on factors like revision and dislocation linked to bone and implant interactions. Importantly, the speaker emphasizes the role of pelvic tilt and spine mobility in postoperative hip functionality, suggesting that these factors can be assessed using preoperative lateral X-rays.



The study's objective is outlined: to investigate how pelvic tilt and spine mobility affect the risk of hip impingement during daily activities. This involves simulating various activities using a validated full-body computational model that calculates hip and spine kinematics based on motion capture data from normal and stiff spines.



The results are depicted through graphs illustrating how different pelvic tilts and spinal mobilities relate to impingement risks across various activities. Observations reveal significant findings, including a strong correlation between posterior pelvic tilt and posterior impingement, with a notable risk during activities like golf swings. Conversely, anterior pelvic tilt is associated with increased anterior impingement risks.



The presentation concludes by stressing the importance of personalized planning in hip surgeries that account for individual anatomical and physiological conditions, advocating for simulation methods that enhance the accuracy of assessing impingement risks unique to each patient.
