Patient Positioning
Patient seated in front of the examiner, hand palm up resting on a examination table.
Probe Positioning
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.
e: effusion
dij: distal interphalangeal joint
Note: Synovitis of the DIJ with effusion in the synovial recess, marked synovial neovascularization showed by doppler signal in a patient with psoriatic arthritis
Note: Synovitis of the DIJ of the thumb with effusion in the synovial recess, marked synovial and periarticular neovascularization showed by doppler signal in a patient with psoriatic arthritis
