Images depicting ultrasonographic changes of the polydioxanone (PDO) device over time and a graph illustrating the median time of the events. a At day 2 the locking case and loop of the device was seen as a hyperechoic ring-like structure with a tail, causing strong acoustic shadowing. b At day 28 the device had an amorphous, fragmented look. c After day 90 most devices had a rounded homogenous, mildly hyperechoic shadowing appearance. d A rounded, smoothly outlined structure was still seen in Horse #3 after 7 months. e In Horse #6, neovascularization was observed with colour Doppler in the region of the device at day 90. f Kaplan-Meier Survival Plot describing the median time when the PDO-device was fragmented (red), had lost its original shape (green) and was no longer visible with ultrasound (blue)
