Answer 1

160 total, with 19 repeatedly observed (in 52% of all cases)

Question 2

anatomy of the lumbosacral trunk

Answer 2

it becomes the sciatic nerve after being joined by the 2° sacral nerve, and passing over the greater ischiatic notch and exit the greater ischiatic foramen

percentage of recovery of animal with peripheral nerve injury

Answer 3

15% had permanent loss of linb function

Question 4

Pelvic canal ratio

Answer 4

hamilton 2009. A-B= cranial border sacrum
C-D= medial cortex acetabulum. 0.97 +- 0.025 in normal cats.

reduction of <10% mild, 10-30% moderate, >30% severe
