Ultrasound-Guided Intra-Articular Injection of the Trapeziometacarpal Joint: Description of Technique
Abstract
Umphrey GL, Brault JS, Hurdle M-FB, Smith J. Ultrasound-guided intra-articular injection of the trapeziometacarpal joint: description of technique.
Objective
To describe a new technique to perform an ultrasound-guided intra-articular injection of the trapeziometacarpal (TMC) joint.
Design
Ultrasound-guided injection of the TMC joint was completed on fresh frozen cadaver hand specimens using diatriazoate meglumine contrast. A fluoroscopic posteroanterior image of the TMC joint was then obtained to verify intra-articular placement of the contrast.
Setting
Anatomy lab in a medical college.
Specimens
Seventeen fresh frozen cadaver hand specimens.
Interventions
Not applicable.
Main Outcomes Measure
Verification of this technique was confirmed using fluoroscopy and contrast.
Results
Sixteen (94%) of 17 joints injected showed contrast material within the TMC joint with a single cutaneous puncture. One intra-articular injection was initially misplaced into the scaphotrapeziotrapezoid joint.
Conclusions
Ultrasound may be used to accurately perform intra-articular TMC injections. Ultrasound provides a viable alternative to fluoroscopy when accurate injection into the TMC joint is required for diagnostic or therapeutic purposes.
