Tibialis anterior distal bursitis. US-guided injection. a, b Longitudinal sonograms obtained over the distal tibialis anterior tendon and the adjacent bursitis. c Axial sonogram obtained before (c) and during (d) US-guided intrabursal injection. The tibialis anterior tendon (arrows) is normal. Note local bursitis (asterisks) probably due to local impingement on tarsal dorsal osteophytes (black arrowheads). In (d) US shows the needle (white arrowheads) correctly positioned inside the bursa. Note injected steroid with resultant posterior comet-tail artifact (curved arrow). Nav navicular, MCn medial cuneiform
