[Three-dimensional construction of the relation between the anterior branches of lumbar nerves 4, 5, lumbosacral trunk and sacroiliac joint].

Objective: To construct a three-dimensional model to demonstrate the relation between the anterior branches of lumbosacral 4,5, lumbosacral trunk, and the pelvis.

Methods: An formaldehyde-fixed adult cadaver was dissected to expose the anterior branches of the lumbar nerves 4 and 5, lumbosacral trunk and the sacroiliac. The mixture of titanium powder and adhesive was smeared on the surface of the major branches of L4 and L5 nerves, lumbosacral trunk, femoral nerves and obturator nerves.
