Background
MR arthrography is an essential diagnostic tool to assess and guide management of labral, ligamentous, fibrocartilaginous, and capsular abnormalities in children. While fluoroscopy is traditionally used for intra-articular contrast administration, ultrasound offers advantages of portability and lack of ionizing radiation exposure for both the patient and proceduralist.
Objective
The purpose of this retrospective study is to quantify technical success and frequency of complications of ultrasound-guided arthrogram injections at our institution.
Materials and methods
This retrospective analysis investigates the results of 217 ultrasound-guided arthrograms of the shoulder, elbow, and hip in patients aged 5–18 years. Successful injection of contrast into the target joint, clinical indication for MR arthrography, and complications were reviewed.
Results
Accurate ultrasound-guided intra-articular administration of contrast into the target joint was successful for 100% of shoulder cases (90/90), 97% of elbow cases (77/79), and 98% of hip cases (47/48). Leak of contrast outside the target joint occurred in 1.4% (3/217) of cases. No major side effects including excessive bleeding, paresthesia, allergic reactions, or infection occurred during or after the procedure. Additionally, no major vessel, nerve, or tendon complications were observed on MR images.
Conclusion
Ultrasound guidance is a reliable, effective, and safe approach to arthrography in children.
