Sciatic nerve distances from different divisions of the sacrotuberous ligament A, B, C and D in 68 cadavers.
Results are expressed as mean±SD. Letters above the bar indicate that these sections differ significantly from each other (a, b, c: P<0.05).

Sciatic nerve distances from different divisions of the sacrotuberous ligament A, B, C and D in Beagles and mongrels.
Results are expressed as mean±SD. Letters above the bar indicate that these sections differ significantly from each other (a, b, c: P<0.05); * indicates the significance between Beagles and mongrels (P<0.05).

Sciatic nerve distance from different divisions of the sacrotuberous ligament A, B, C and D in small, medium, and large mongrel groups.
Results are expressed as mean±SD. Letters above the bar indicate that these sections differ significantly from each other (*: P<0.05).

Fig 6.
Anatomical landmarks used for locating the left sciatic nerve and the sacrotuberous ligament in a dog.
A line has been drawn to connect the cranial dorsal iliac spine and the ischiatic tuberosity. Another line is drawn perpendicular to the distal third of the first line. A third line is drawn from the dorsal iliac spine parallel to the midline, crossing the perpendicular line. The midway of the perpendicular line between the intersection of the cranial dorsal iliac spine and the ischiatic tuberosity is the approximate location of the sciatic nerve (needle). A line drawn from the distal ischiatic tuberosity to the sacrococcygeal joint is the approximate surface projection of the sacrotuberous ligament.
