Since these segmental nerves communicate just above the transversus abdominis muscle, the subfascial spread of local anesthetic can provide anterolateral abdominal wall analgesia [23].
Subsequent to the perpendicular insertion, localization of the needle was detected under direct laparoscopic vision with the help of its trace, and when the needle's tip was positioned at the fascial space between the internal oblique and the transversus abdominis muscle, 15 cc of 0.25% bupivacaine was injected bilaterally.

In my experience performing CST, I discovered an extra space that lies out lateral to the rectus sheath where I was able to access the plane between the transversus abdominis muscle and the internal oblique muscle and create a space to lay a large mesh.

The results of these studies show that the most important risk factors for such injuries are previous injuries (hamstring and groin), (7) reduced muscle strength and muscle strength imbalances (reduced hamstring to quadriceps strength ratio), (7), (8), (9) reduced pre-season range of motion (ROM), (10), (11) reduced core muscle strength, and delayed activation of the transversus abdominis muscle. (7) The following were not identified as significant risk factors for hamstring strains: age, body size, limb dominance and playing position.
These studies provide evidence of the ability of ultrasound to measure transversus abdominis muscle activation at low levels of contraction.
