Which of these findings is consistent with the basic distortion pattern for a right posterior innominate?

1. Left sacral rotation

2. Right pelvic rotation

3. Left posterior innominate rotation

4. Right anterior innominate rotation

The correct answer is: Right pelvic rotation

Identifying the findings associated with the distortion patterns of the pelvis and sacrum is crucial in chiropractic practice. In the case of a right posterior innominate, the right side of the pelvis has rotated backward in relation to the sacrum. Right pelvic rotation is consistent with a right posterior innominate because when this distortion pattern occurs, it often leads to a compensatory mechanism where the entire pelvis rotates to the right. This means that the left side of the pelvis is pushed forward compared to the right side, which matches the automatically occurring rotation of the pelvis as a whole. Understanding these patterns helps practitioners assess and treat conditions related to pelvic alignment effectively. The other findings, such as left sacral rotation, left posterior innominate rotation, and right anterior innominate rotation, would suggest different pelvic and sacral positions that wouldn't align with the characteristics of a right posterior innominate, illustrating the importance of recognizing these underlying patterns for accurate diagnosis and treatment planning.
