Correlation of Spinopelvic Parameters and Acetabular Cup Orientation - Clinical Trial

What is the Purpose of this Study?

We are doing this study to create a numeric algorithm (mathematical formula) to help determine the change in the total hip replacement cup orientation compared to the movement of the pelvis and spine between the standing and seated positions.
What we learn from this study might be used to help calculate placement of the hip replacement cup in a specific orientation for a people which may result in a decrease in the risk of pain, instability, and

What is the Condition Being Studied?

Hip arthritis that may require a hip replacement

Who Can Participate in the Study?

Adult men and women who:
Are candidates for primary total hip replacement for osteoarthritis
Women must not be able to get pregnant (for example, post-menopausal, hysterectomy, etc.).

Age Group

What is Involved?

If you choose to join this study you will have you will have two extra x-rays before your surgery, one while you are in a sitting position and one while you are in a standing position.
