Description[edit | edit source]
The sinuvertebral nerve (or Luschka nerve) is a recurrent nerve that originates from the ventral ramus rande-entering the spinal canal via the intervertebral foramina to innervate the anulus fibrosus of the intervertebral disc, the ligaments and periosteum of the spinal canal. Its complex anatomy and relationship to discogenic pain have warranted great interest among clinical anatomists owing to its sympathetic contribution to the lumbar spine. Knowledge of the nerve has been used to design a variety of diagnostic and treatment procedures for chronic discogenic pain .
Root[edit | edit source]
Branches[edit | edit source]
Sinuvertebral nerve originates from the ventral ramus of spinal nerves.
Function[edit | edit source]
Innervate multiple meningeal and non-meningeal structures. Is a somatic and vegetative nerve.
Motor[edit | edit source]
Sensory[edit | edit source]
- Anulus fibrosus of the intervertebral disc;
- Ligaments and periosteum of the spinal canal;
- Anterior portion of the dura mater.
Clinical relevance[edit | edit source]
Although the sinuvertebral nerve fibers are said to terminate in the outer anulus, it is now widely accepted that this end point is not permanent. Studies of healthy patients normally show neural penetration of the anulus at about 3 mm , corresponding to the three outer lamellae. However, degenerative discs have shown penetration of nerve fibers as far as the inner one third in one study , and into the nucleus pulposus in another .
Assessment[edit | edit source]
Provocative discography (has proved significantly more effective for diagnosing degenerative disc disease than magnetic resonance imaging) .
