Because each vertebra can cause pain in different areas of the body, the pain from the disease can be sensed in the back, leg, neck area, or even the arms. When the spinal canal begins to lose its gap and gets thinner, it can cause pain in the neck, which can also cause a numb feeling in the arms and hands.
The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.
The bonobo differs by having four lumbar vertebrae. Caudal vertebrae are the bones that make up the tails of vertebrates. [35] They range in number from a few to fifty, depending on the length of the animal's tail. In humans and other tailless primates, they are called the coccygeal vertebrae, number from three to five and are fused into the ...
Myelomalacia is a pathological term referring to the softening of the spinal cord. [1] Possible causes of myelomalacia include cervical myelopathy, hemorrhagic infarction, or acute injury, such as that caused by intervertebral disc extrusion.
Caudal vertebrae are the vertebrae of the tail in many vertebrates. In birds, the last few caudal vertebrae fuse into the pygostyle, and in apes, including humans, the caudal vertebrae are fused into the coccyx. In many reptiles, some of the caudal vertebrae bear ribs, the caudal ribs, though these are often fused with the vertebrae. [1]
Current treatment options include CSF aspiration, fibrin-glue therapy, laminectomy with wrapping of the cyst, among other surgical treatment approaches. Interventional treatment of Tarlov cysts is the only means by which symptoms might permanently be resolved due to the fact that the cysts often refill after aspiration.
Treatment of spina bifida during pregnancy is not without risk. [73] To the mother, this includes scarring of the uterus. [73] To the baby, there is the risk of preterm birth. [73] Broadly, there are two forms of prenatal treatment. The first is open fetal surgery, where the uterus is opened and the spina bifida repair performed.
Caudal regression syndrome, or sacral agenesis (or hypoplasia of the sacrum), is a rare birth defect. It is a congenital disorder in which the fetal development of the lower spine—the caudal partition of the spine—is abnormal. [1] It occurs at a rate of approximately one per 60,000 live births. [2]
