Study Summary
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.
Primary Outcome
A quantitative relationship will be generated correlating change in cup anteversion (change in degrees) to change in pelvic tilt (change in degrees) at given inclinations (degrees) as simulated in the model. Statistical analysis will then be performed. Significance of changes between standing and sitting in pelvic tilt and cup anteversion will be assessed with t-test or non-parametric equivalent if appropriate with significance p\<0.05. The effect of change in pelvic tilt on change in functional
