Official title
Measurement and Quantitative Correlation of Spinopelvic Parameters and Acetabular Cup Orientation Between Standing and Sitting to Define a Better Functional Anteversion Safe Zone in Total Hip Arthroplasty
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In total hip arthroplasty, cup anteversion is an important factor in stability. Lewinnek's safe zone and functional anteversion are often used to assess appropriate orientation. However, these approaches do not consider the effect of the spinopelvic chain and lumbar mobility when in the seated position. This study will measure functional anteversion when standing and sitting with patient-specific computer models and define a quantitative relationship between the change in functional anteversion and spinopelvic parameters. This will challenge the historical paradigm of the safe zone and provide a tool to define anteversion based on a patient's mechanics and reduce risk of dislocation.
