Vertebrectomia total e estabilização com pinos e PMMA como tratamento para luxação vertebral crônica associada à exposição de vértebra torácica – relato de caso

Abstract

The spine plays an important anatomical and physiological role in the animal organism, with spinal cord support and protection being two of its main functions. The spinal cord is a component of the central nervous system, which acts in the transmission of information from organs and limbs to the brain, and vice versa. Injuries resulting from being run over are the main causes of vertebral fractures and dislocations, causing varying degrees of spinal and spinal injuries. The present study aims to report the occurrence of traumatic injury to the spine of a mixed breed dog, aged four years, resulting in a T10-11 dislocation, with T10 exposure and spinal section, with the patient showing signs of an upper motor neuron and absence of deep nociception in pelvic limbs. The treatment of choice was T10 vertebrectomy, associated with the alignment of T9-11 with the introduction of pins and fixation with polymethylmethacrylate (PMMA) associated with ceftriaxone. Due to a lesion in the parietal pleura during the surgery, thoracostomy was also chosen to introduce a chest tube, which remained in the patient for four days. In the postoperative period, the patient presented a satisfactory recovery, and it was recommend that tutors make a wheelchair in order to facilitate their mobility. The technique proved to be satisfactory for minimizing infections that could occur in open fractures, as well as improving the patient's quality of life, avoiding chronic pain.
