In
human anatomy, the
sacral plexus is a
nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the
pelvis. It is part of the
lumbosacral plexus and emerges from the
lumbar vertebrae and
sacral vertebrae (L4-S4). A
sacral plexopathy is a disorder affecting the nerves of the sacral plexus, usually caused by trauma, nerve compression, vascular disease, or infection. Symptoms may include pain, loss of motor control, and sensory deficits.
