Kyphosis in dogs is an abnormal dorsal curvature of the spinal column, which is a spread consequence of congenital malformations of the vertebrae, and also directly connected with of recurrent and progressive diseases of the spinal cord. is pathology characterized multifactoriality with the presence of dinamic and statistic factors, including vertebral instability, subluxation of the vertebrae and stenosis of spinal canal. Early, in kyphosis of the spinal column, all operations were performed using dorsal laminectomy or hemilaminectomy, and all structures, namely wires, screws, were introduced dorsally through the vertebral arches in their bodies. Each of previously described methods of surgical intervention is a variant of dorsal or dorso-lateral implantation, which was accompanied by the occurrence of di cult situations. In this regard, the aim of this study is to improve the methods of correction of kyphosis deformities in dogs. e study were involved 18 dogs of small and medium breeds under the age of 1 year. 8 dogs were operated on by dorsal laminectomy metod using a screws and polymethyl methacrylate (or bone cement) and 10 dogs were operated by transthoracic stabilization metod. As a result of the studies, data were found that the method of transthoracic xation of the spinal column is much better then methods described earlier, since when using this method, the installation of metal structures is more durable, also there is less risk of spinal cord injury, because the procedure takes place without access to the spinal canal.
