According to a 2008 study, the incidence of discitis in the United States is around 0.4 to 2.4 per 100,000 people each year depending on age group. [5] According to a later 2016 study, the combined prevalence of discitis and vertebral osteomyelitis with or without spinal epidural abscess for persons under 20 years old is uncommon (0.3 per 100,000 persons), and higher in older patients (6.5 per ...
Vertebral osteomyelitis often attacks two vertebrae and the corresponding intervertebral disk, causing narrowing of the disc space between the vertebrae. [6] The prognosis for the disease is dependent on where the infection is concentrated in the spine, the time between initial onset and treatment, and what approach is used to treat the disease.
Acute osteomyelitis almost invariably occurs in children who are otherwise healthy, because of rich blood supply to the growing bones. When adults are affected, it may be because of compromised host resistance due to debilitation, intravenous drug abuse, infectious root-canaled teeth, or other disease or drugs (e.g., immunosuppressive therapy).

Myelitis occurs due to various reasons such as infections. Direct infection by viruses, bacteria, mold, or parasites such as human immunodeficiency virus , human T-lymphotropic virus types I and II (HTLV-I/II), syphilis, lyme disease, and tuberculosis can cause myelitis but it can also be caused due to non-infectious or inflammatory pathway ...
Because degenerative disc disease is largely due to natural daily stresses, the American Academy of Orthopaedic Manual Physical Therapists have suggested it is not truly a "disease" process. [6] This water loss makes the discs more flexible and results in the gradual collapse and narrowing of the gap in the spinal column. As the space between ...
Two of the genetic disorders that may affect spinal tumors, include Von Hippel-Lindau disease and Neurofibromatosis 2. Von Hippel-Lindau disease is a non-cancerous tumor of blood vessels that occur in the brain, spinal cord, or even tumors in the kidneys. The Neurofibromatosis 2 is a non-cancerous tumor that usually affects the nerves for hearing.
Chronic recurrent multifocal osteomyelitis (CRMO) is a rare condition (1:1,000,000), in which the bones have lesions, inflammation, and pain. It is called multifocal because it can appear in different parts of the body, primarily bones, and osteomyelitis because it is very similar to that disease, although CRMO appears to be without any infection .
Neuromyelitis optica spectrum disorders (NMOSD) are a spectrum of autoimmune diseases characterized by acute inflammation of the optic nerve (optic neuritis, ON) and the spinal cord . [ 1 ] [ 2 ] [ 3 ] Episodes of ON and myelitis can be simultaneous or successive.
