Microanatomy of the Lumbar Plexus
Nerve roots, as well as related motor, sensory, and sympathetic axons, were examined at their origins in the subarachnoid space and along their exits through the intervertebral foramina. Four cross-sectional…
Lesions Involving the Lumbar Plexus
Anatomy The lumbar plexus, composed of the ventral rami of the L1–L4 spinal nerve roots, travels into and is formed within the body of the psoas major muscle, coalescing to…
Surgical Techniques for Approaching the Lumbosacral Plexus
The posterior 1 surgery (▶ Fig. 17.1) is a paraspinal approach that was originally described as an alternative conduit to the lumbar spine. It went between the lateral board of…
High-Resolution Magnetic Resonance Neurography of the Lumbar Plexus
Magnetic resonance neurography (MRN) is a recent addition to the set of tools for the assessment of the lumbar plexus (LP) and peripheral nerves. The objective of this chapter is…
Dermatomes and the Lumbar Plexus
There are various proposed models that mark the distributions for these dermatomes. As such, significant variations exist in the literature. In this chapter, we will briefly describe the general map…
