Researchers studied patients aged one to 24 undergoing lower extremity surgery and lumbar plexus block. They found a strong linear relationship between lumbar plexus depth and PSIS-ICL distance. The predicted depth was within 10 mm of actual depth in 92 percent of patients.
The authors suggest the PSIS-ICL distance can guide ultrasound location and needle length.
