Is It a Lumbar ESP or a T-Lip?

I'm just trying to think that must be really quite bad luck with a lumbar ESP to get lower limb paralysis. That fascia is quite thick in the lumbar region. So it's almost like an MTP. I'm truly hitting the dorsal surface of the transverse process and keeping it in the ESP muscle or lifting. In terms of T-lip, I am not sure if it's just our patient population or maybe I'm just not very good at ultrasound.
