(A) Compound transverse sonogram (10 MHz linear tendon probe, 6 cm depth) at the dorsal aspect of the sacroiliac region of a 6-year-old cow showing sacral tuber (ST), the thoracolumbar fascia (TLF), the dorsal portion of the dorsal sacroiliac ligament (D-DSIL). first sacral spinous process (S1), dorsal direction (D) and ventral direction. (B) Compound longitudinal sonogram (14 MHz linear tendon probe, 5cm depth) at the dorsal area of sacral tuber of a 7- year- old cow showing sacral tuber (ST), the dorsal portion of the dorsal sacroiliac ligament- thoracolumbar fascia combination (D-DSIL-TLF), cranial margin of sacral tuber (CR-P), caudal margin of sacral tuber (CD.P), cranial direction (CR), caudal direction (CD), dorsal direction (D) and ventral direction (V). (C) Compound longitudinal sonogram at the dorsal area of sacral tuber of the same animal in Figure. 1B. showing the dorsal aspect of the dorsal sacroiliac ligament (D-DSIL), thoracolumbar fascia (TLF), sacral tuber (ST), cranial direction (CR), caudal direction (CD), dorsal direction (D) and ventral direction (V). (D) Transverse sonogram (10 MHz linear tendon probe, 6 cm depth) of an 8-year-old cow showing the lateral aspect of the dorsal sacroiliac ligament (L-DSIL), the lateral sacral crest (LSC), the sacral spinous process (SSP), lateral direction (LAT), medial direction (MED), dorsal direction (D) and ventral direction (V).(A) Compound transverse sonogram (10 MHz linear tendon probe, 6 cm depth) at the dorsal aspect of the sacroiliac region of a 6-year-old cow showing sacral tuber (ST), the thoracolumbar fascia (TLF), the dorsal portion of the dorsal sacroiliac ligament (D-DSIL). first sacral spinous process (S1), dorsal direction (D) and ventral direction.
