What disease is vertebral arch tuberculosis?

summary

What disease is vertebral arch tuberculosis? Vertebral arch tuberculosis refers to the lesions limited to the pedicle, lamina, spinous process or transverse process, not secondary to the expansion of vertebral tuberculosis to the pedicle, transverse process or superior and inferior articular process. This disease is relatively rare, the most common site is thoracic vertebrae, followed by lumbar and cervical vertebrae. What disease is vertebral arch tuberculosis? Come and study with me.

What disease is vertebral arch tuberculosis?

First, etiology; Incidence rate of vertebral tuberculosis is high in bone and joint tuberculosis, while vertebral arch tuberculosis is rare. Tuberculosis of vertebral arch is mostly in young adults and less in children. It is mainly caused by the colonization of Mycobacterium tuberculosis in this area with the invasion of blood flow. The disease is close to the body surface, the course of disease is shorter than that of spinal tuberculosis, near the midline of spine, mass, abscess or sinus often appear. There was no deformity of spine and no obvious limitation of movement.

Second, clinical manifestations; The incidence rate of male and female gender is obviously different. Most of them are in young adults. The most common site of the disease was thoracic vertebrae, followed by lumbar vertebrae and cervical vertebrae. Most of the lesions surround the spinal cord on three sides of the thoracic vertebral arch, and the compression of the spinal cord comes from the posterior side. Therefore, 25% - 50% of the cases are complicated with paraplegia, which is more frequent than that of vertebral tuberculosis; In addition to the pain of the affected area, radicular radiation pain is also more common.

Third, complications; Masses, abscesses or sinuses are common. There was no deformity of spine and no obvious limitation of movement. Most of the abscesses of vertebral arch tuberculosis are located at the back of the spine near the focus, but a few abscesses of lumbar transverse process tuberculosis can not only form a square shape at the back of the spine, but also invade the psoas major muscle attached to the transverse process, forming psoas major muscle abscess and downward flowing iliac fossa abscess.

matters needing attention

treatment; Because of its small volume, the location of lesions is far more superficial than that of vertebral tuberculosis, so surgical treatment is preferred. 1. A few vertebral arch tuberculosis; If the disease is mild, the course of disease is short, and there is no local abscess, fistula or neurological symptoms, non-surgical treatment can be considered, that is, the disease can be cured mainly by anti tuberculosis drugs. 2. Most vertebral arch tuberculosis; We should actively carry out debridement under the treatment of systemic antituberculosis drugs to avoid the progression of lesions into the spinal canal, causing neurological symptoms and paraplegia. The patients were treated with antituberculosis drugs for 6-9 months.
