Figure 6.

Changes in finger extensor tendon at the place of attachment to the distal phalanx. Longitudinal scan of the finger extensor tendon at the place of attachment to the distal phalanx of the hand. (A) Thickening of the tendon at the site of insertion (arrow). Effusion presented as hypoechoic fluid around tendon sheath (asterisk), (B) erosion presented as a localized bone loss at the site of tendon insertion (yellow arrow). Calcification presented as hyperechoic structure in the area of the distal attachment of the extensor tendon (green arrow).
