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.

After the puncture needle is in the skin, the longitudinal section of the Xplane mode can be adjusted to keep the needle in the proposed plane.
The First Medical Center of the PLA General Hospital
Beijing, China
The first-attempt success rate
The proportion of successful entries into the anterior synovial recess and completion of medication injection on the first needle insertion, without adjusting needle tip direction
Time frame: during operation
The final success rate
The proportion of successful medication injections completed with no more than two needle insertions
Time frame: during operation
Puncture time
The duration from the insertion of the puncture needle into the skin until saline can be injected into the joint cavity without significant resistance
Time frame: during operation
The number of needle adjustments
The number of times the puncture needle was retracted slightly and the insertion direction was adjusted upon noticing that the needle tip had deviated from the intended trajectory
Time frame: during operation
The operator confidence score
Based on the operator's level of confidence during the puncture process, with 1 point indicating a lack of confidence in the success of the first attempt, 2 points indicating moderate confidence, and 3 points indicating strong confidence
Time frame: during operation
Complications
Refer to adverse reactions occurring during the puncture process, including hematomas resulting from damage to surrounding blood vessels, pain or numbness due to nerve injury, toxic reactions caused by anesthetic entering the bloodstream, and postoperative infections
Time frame: during operation
