3. The Phalanges of the Foot The phalanx ends in a crescent-shaped rough cap of bone epiphysis — the apical tuft (or ungual tuberosity/process) which covers a larger portion of the phalanx on the volar side than on the dorsal side. Two lateral ungual spines project proximally from the apical tuft.
The fifth lumbar spinal nerve 5 (L5) [5] originates from the spinal column from below the lumbar vertebra 5 (L5). L5 supplies many muscles, either directly or through nerves originating from L5. They are not innervated with L5 as single origin, but partly by L5 and partly by other spinal nerves. The muscles are: gluteus maximus muscle mainly S1
However, because the severity of symptoms does not correlate well with the degree of stenosis and nerve root compression, a clear understanding of the specific pathogenesis remains challenging. [ 7 ] It is currently unknown which exact cellular mechanisms within the body causes the pain of NC as a response to the compression of spinal nerves.
Weight loss, to relieve symptoms and slow the progression of the stenosis; Physical therapy to support self-care. [37] Also may give instructions on stretching and strength exercises that may lead to a decrease in pain and other symptoms. Lumbar epidural steroid or anesthetic injections have low quality evidence to support their use. [36] [38]
MRI of a lumbar spinal stenosis L4-L5. L4-L5 antherolisthesis of grade I. Hypertrophy of interspinous ligaments in relation to Baastrup's disease. 67 years old man. MRI is the preferred method of diagnosing and evaluating spinal stenosis of all areas of the spine, including cervical, thoracic, and lumbar.
The sciatic nerve, also called the ischiadic nerve, is a large nerve in humans and other vertebrate animals. It is the largest branch of the sacral plexus and runs alongside the hip joint and down the right lower limb. It is the longest and widest single nerve in the human body, going from the top of the leg to the foot on the posterior aspect ...
The lumbosacral trunk is formed by the union of the entire anterior ramus of lumbar nerve L5 and a part of L4 [clarification needed]. [1] [2] [3] L4 first issues its branches to the lumbar plexus, then emerges from the medial border of the psoas muscle [3] to unite with the anterior ramus of L5 just superior to the pelvic brim to form the thick, cord-like trunk which [4] crosses the pelvic ...
The superior gluteal nerve is a mixed (motor and sensory) nerve of the sacral plexus that originates in the pelvis. It provides motor innervation to the gluteus medius , gluteus minimus , tensor fasciae latae , and piriformis muscles; it also has a cutaneous branch.
