Precise localization of motor branching and motor points: a cadeveric study.

In order to facilitate precise localization of motor nerves and motor points, and to increase effectiveness and minimize complications of neurolytic blocks. Locations of motor branching points and motor points of 31 cadavers were measured as relative to medial femoral condyle and mid posterior calf line. Needle insertion points 1.

Precision of a needle localization technic in the lumbosacral multifidus muscles for segmental specific needle electromyographic study: a cadaveric study.

The authors studied 14 cadavers to evaluate the claimed precision of needle placement into segment specific multifidus fascicles when using the "paraspinal mapping" electromyographic technic. Injection of acrylic dye was made according to landmarks proposed by Haig. The dissection showed 86.
