ObjectiveTo describe a new technique to perform an ultrasound-guided intra-articular injection of the trapeziometacarpal (TMC) joint.DesignUltrasound-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.SettingAnatomy lab in a medical college.SpecimensSeventeen fresh frozen cadaver hand specimens.InterventionsNot applicable.Main Outcomes MeasureVerification of this technique was confirmed using fluoroscopy and contrast.ResultsSixteen (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.ConclusionsUltrasound 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.
