The local anesthetic injectate spread with fascial plane blocks and corresponding clinical outcomes may vary depending on the site of injection. We developed and evaluated a supra-iliac approach to the anterior quadratus lumborum (QL) block and hypothesized that this single injection might successfully block the lumbar and sacral plexus in cadavers and provide analgesia for patients undergoing hip surgery. ⋯ This cadaveric study and case series show that a supra-iliac approach to the anterior QL block involved T10--L3 nerve territories and dermatomal coverage with no sacral plexus spread. This technique may have clinical utility for analgesia in hip surgery.

Comparative Study
Ultrasound-Guided Versus Landmark-Based Approach to the Distal Suprascapular Nerve Block: A Comparative Cadaveric Study.
To compare the accuracy of distal suprascapular nerve (dSSN) blockade performed with the use of ultrasound-guided regional anesthesia (USRA) versus with a landmark-based approach (LBA). A secondary aim was to describe the anatomic features of the sensory branches of the dSSN. ⋯ The present study demonstrates that a landmark-based approach to anesthetic blockade of the distal suprascapular nerve is accurate and can be performed by orthopaedic surgeons lacking experience in ultrasound-guided anesthetic techniques.

Observational Study
Anatomical evaluation of the extent of spread in the erector spinae plane block: a cadaveric study.
The erector spinae plane (ESP) block is an interfascial analgesic technique first described as an alternative for pain control at the thoracic level. The objective of this observational study was to determine the anatomical spread of dye following a T7 ESP block in a cadaveric model. ⋯ The results suggest that the ESP block reaches a wide range of the posterior rami of spinal nerves without diffusion into the paravertebral space or involvement of the anterior rami.
