<\/i><\/i><\/span>Atlanto-axial instability <\/span><\/a><\/h4><\/div>
\n

What it is?<\/b><\/p>\n

A instabilidade atlanto-axial consiste no movimento excessivo da articula\u00e7\u00e3o entre as v\u00e9rtebras C1 e C2. \u00c9 normalmente causada por anomalias de desenvolvimento do dente do \u00e1xis (parte da v\u00e9rtebra C2) ou fraco suporte ligamentar. Esta instabilidade pode levar a subluxa\u00e7\u00e3o vertebral o que ir\u00e1 comprimir a espinal medula. Os sinais cl\u00ednicos podem variar desde dor no pesco\u00e7o a tetraparesia\/plegia n\u00e3o ambulat\u00f3ria.<\/p>\n

How are they diagnosed?<\/b><\/p>\n

Exame neurol\u00f3gico e exames complementares de imagem (radiografia, TAC ou RM).<\/p>\n

What is the treatment?<\/b><\/p>\n

Rapid diagnosis influences the outcome of the therapy applied. Surgery for vertebral stabilization<\/u><\/a> is the preferred treatment, with the highest success rate. Once diagnosed, the patient should receive drug therapy and the neck should be immobilized.<\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Herniated disc<\/span><\/a><\/h4><\/div>
\n

What it is?<\/b><\/p>\n

A herniated disc can arise as a result of a degenerative disease of components of the intervertebral disc or as an acute event resulting from trauma.<\/p>\n

The affected intervertebral disc will cause compression on the spinal cord, which passes inside the vertebral canal, giving rise to the symptoms of the disease. Depending on the degree of compression, the speed with which the pathology develops and the chronicity of the disease, animals can show various signs ranging from pain to loss of neurological abilities (often recognized by the owner as dragging limbs or loss of ambulatory capacity).<\/p>\n

How are they diagnosed?<\/b><\/p>\n

By means of a neurological examination and complementary imaging tests (CT or MRI).<\/p>\n

What is the treatment?<\/b><\/p>\n

Treatment depends on the clinical presentation and can be medicated or surgical. Surgery consists of opening a window between the vertebrae to decompress the spinal cord. The technique used will depend on the location of the lesion: when cervical, the ventral slot<\/u><\/a>when thoracolumbar, the lateral vertebral hemilaminectomy<\/u><\/a> e quando sacro-lombar \u00e9 utilizada a t\u00e9cnica de laminectomia vertebral dorsal.<\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Vertebral fracture\/luxation<\/span><\/a><\/h4><\/div>
\n

What it is?<\/b><\/p>\n

It most often occurs as a result of trauma. It occurs most frequently in the thoracolumbar spine. After the trauma, the instability and movement of the bone segments can continue to cause spinal cord injury. The signs presented can be varied, from local pain to loss of ambulatory capacity.<\/p>\n

How are they diagnosed?<\/b><\/p>\n

Exame neurol\u00f3gico em associa\u00e7\u00e3o com exame complementar de imagem (radiografia ou TAC).<\/p>\n

What is the treatment?<\/b><\/p>\n

After trauma, the primary objective is to stabilize the affected segment of the spine and apply shock treatment. Depending on the type of injury and the patient's evolution, it may make sense to opt for medical management alone, but deterioration in the clinical neurological state indicates the need for surgical treatment for stabilization.<\/p>\n

The surgical technique will depend on the characteristics and location of the injury. Vertebral stabilization may be necessary in situations of cervical vertebral fracture or dislocation, toracic<\/u><\/a>lombar or lombo-sacral.<\/u><\/a>.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

<\/i><\/i><\/span>Ventral slot, lateral vertebral hemilaminectomy or dorsal vertebral hemilaminectomy<\/span><\/a><\/h4><\/div>
\n

What is it?<\/b><\/p>\n

The ventral slot is a surgical technique used in situations where decompression of the cervical spinal cord is necessary. The surgical access is ventral.<\/p>\n

Lateral or dorsal vertebral hemilaminectomy is used to decompress a segment of the remaining spinal cord. Its access is lateral or dorsal.<\/p>\n

Common pathologies in which these techniques are recommended:<\/b><\/span> intervertebral disc herniation.<\/span><\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>vertebral stabilization<\/span><\/a><\/h4><\/div>
\n

<\/u>What is it?<\/b><\/p>\n

Spinal stabilization can be achieved using various surgical techniques and materials. It is common to use screws alone or a plante and screws. The aim is to eliminate movement between two unstable segments.<\/p>\n

Common pathologies in which these techniques are recommended: <\/b>altanto-axial instability, lombar vertebral stabilization, sub\/luxation.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
