Assessing the Ompact of Neutral Pelvic Positioning on Bone Repositioning Quality in Pelvic Radiotherapy Patients

This study explores whether achieving a neutral pelvic position improves bone repositioning quality for patients undergoing pelvic radiotherapy. While Intensity-Modulated Radiotherapy (IMRT) and Image-Guided Radiotherapy (IGRT) have enhanced target volume precision and reduced side effects, effective patient positioning remains crucial. However, rotational adjustments are limited without a specialized robotic table. Current immobilization devices, customizable or not, show limited impact on positioning accuracy, with mixed results on the use of knee and foot supports. A pilot study identified significant rotational variation, and to address this, a \"glute bridge\" maneuver is proposed to ensure a neutral pelvic position. This randomized study will evaluate the impact of this maneuver on positioning quality when combined with immobilization and skin markers.
