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

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

The goal of this clinical trial is to compare the safety and accuracy of single-plane and real-time biplane ultrasound imaging in guiding hip joint injections and explore the application effects of imaging technology in hip joint injections.

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.

Inclusion Criteria:

1.15 to 80 years of age; 2.hip joint pain and/or limited hip joint mobility; 3.physical examination and imaging studies indicating hip joint pathology; 4.pain duration exceeding 6 months with no significant improvement after conservative treatment; 5.patients scheduled for hip arthroscopy.

Exclusion Criteria:

1. a history of hip joint surgery;
2. the presence of lumbar disease, ankylosing spondylitis, or sacroiliac-joint pathology;
3. femoral head necrosis;
4. drug allergies;
5. inability to cooperate, or other contraindications to puncture.
