Dorsolateral percutaneous discectomy for the treatment of the hansen type II herniated disc of the T11-L6 segments in dogs: A study on cadavers. Rev. Fac. Cienc. Vet.

The purpose of this study was to describe surgical approach for a percutaneous discectomy of the T11-L6 intervertebral discs in canine cadavers. A percutaneous dorsolateral approach, guided by fluoroscopy, at the level of the T11 to L6 intervertebral discs in six healthy adult fresh canine cadavers of different breeds was performed. A minimally invasive mechanical percutaneous discectomy with a 2-mm forceps and a thermal discectomy with radiofrequency, were carried out. Both the percutaneous approach and the discectomy were possible in 96% of the samples. The average distance of needle penetration with respect to the midline was 4.3 ± 1276 cm. With respect to the horizontal plane, the mean angle was 50.1 ± 14785 degrees. The amount of disc material removed was approximately 10 mm, and the implementation of the entire procedure left a 4 mm wound. It was demostrated that the dorsolateral percutaneous approach in dogs enables a direct access to the intervertebral disk through a minimally invasive procedure. Percutaneous discectomy could be an alternative for decompression in patients with degenerative disc pathologies and protruded hernias in the thoracolumbar segment. It is deemed clinical studies to evaluate the efficacy of this procedure.
