Place the transducer on a longitudinal planes over the joints and tendons of interest. Do not use any pressure – especially while looking for effusion or using doppler mode. Use dynamic scanning to check the movement of the tendons during flexion / extension or against resistance to check the pulleys.
Note: Osteoarthrosis of the saddle-shaped trapeziometacarpal (TMC) joint of the thumb with osteophytes and effusion
Note: “activated” rhizarthrosis with effusion, synovial proliferation and weak positive doppler signal, bony irregularities.
