To locate this point, observe the rump of the horse from the side to determine the highest point of the rump as the horse is standing normally, and place your index finger in the midline at this point.



Feel for a depression in the midline which is the lumbosacral space between the 6th lumbar vertebra and the 1st sacral vertebra.



Insertion is classically 3.5 Tsun, but for practical purposes a needle can be inserted to a depth of just 2.5cm or deep enough to anchor it in place
