Single-plane Versus Real-time Biplane Approaches for Ultrasound-Guided Hip Joint Injection: A Prospective Randomized Controlled Clinical Study

Real-time biplane imaging, an emerging ultrasound technology, uses a three-dimensional (3D) matrix transducer to display simultaneously he longitudinal and transverse intersecting planes on a single screen without requiring rotation of the transducer. The modality displays the puncture path in real-time and exhibits the spatial relationship between the needle tip and the target site, as well as surrounding structures during guided puncture. This technology significantly improves the puncture success rate and reduces complication rates in procedures such as the placement of intrahepatic bile duct drains and central venous catheters. However, this technology has not yet been implemented for hip joint injections. Therefore, we compared the safety and accuracy of single-plane and real-time biplane ultrasound imaging in guiding hip joint injections and explored the application effects of imaging technology in hip joint injections.
