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.
