“…Surgical treatment of degenerative lumbosacral disease has been recommended for dogs with severe pain . Decompressive surgery is considered an appropriate technique to relieve compression of the cauda equina and nerve roots in dogs with degenerative lumbosacral stenosis (DLSS), and dorsal laminectomy with or without annulectomy and partial discectomy is currently the most commonly performed surgery . Clinical results with this technique have shown to have overall success rates between 79% and 93.2% .…”

Objective: To determine the biomechanical behavior of a novel distractionstabilization system, consisting of an intervertebral distraction bolt, polyaxial screws, and connecting rods, in the canine lumbosacral spine.Study design: Biomechanical study.Sample population: Cadaveric canine lumbosacral spines (L4-Cd3) (N 5 8).Methods: Cadaveric lumbosacral spines were harvested, stripped of musculature, mounted on a 4-point bending jig, and tested in extension, flexion, and lateral bending using nondestructive compressive axial loads (0-150 N). Angular displacement was recorded from reflective optical trackers rigidly secured to L6, L7, and S1. Data for primary and coupled motion were collected from intact spines, after destabilization at L7-S1, and following surgical stabilization with the new implant system.Results: As compared with the intact spine, laminectomy resulted in a modest increase in angular displacement at L6-L7 and a marked increase at L7-S1. Instrumentation significantly reduced motion at the operated level (L7-S1) with a concomitant increase at the adjacent level (L6-L7). Conclusion:The combination of a polyaxial pedicle screw-rod system and intervertebral spacer provides a versatile solution of surgical stabilization of the lumbosacral joint following surgical decompression in the canine lumbosacral spine. The increase in motion at L6-L7 may suggest the potential for adjacent level effects and clinical trials should be designed to address this question.Clinical relevance: These results support the feasibility of using this new implant system for the management of degenerative lumbosacral disease in dogs. The increase in motion at L6-L7 may suggest the potential for adjacent level effects and clinical trials should be designed to address this question.

“…It is characterized by abnormal motion pattern and loss or lack of load‐bearing properties leading to intervertebral disc degeneration and herniation, as well as compensatory new bone production and thickening of surrounding soft tissue structures, such as hypertrophy of the interarcuate ligament, epidural fibrosis, and degenerative facet joint disease . Conservative and surgical treatments have both been described . Conservative treatment is based on pain management through oral administration of nonsteroidal antiinflammatory drugs, body weight reduction, and change in exercise pattern.…”

“…Conservative treatment is based on pain management through oral administration of nonsteroidal antiinflammatory drugs, body weight reduction, and change in exercise pattern. Surgical treatment, on the other hand, aims at decompressing the cauda equina and freeing entrapped nerve roots by dorsal laminectomy, distraction and fusion, or a combination of both . Medical treatment tends to be ineffective long‐term, whilst many intra, early, or late postoperative complications have been described with surgical treatment .…”

In human medicine, spinal pain and radiculopathy are commonly managed by computed tomography (CT)-guided facet joint injections and by transforaminal or translaminar epidural injections. In dogs, CT-guided lumbosacral epidural or lumbar facet joint injections have not been described. The aim of this experimental, ex vivo, feasibility study was to develop techniques and to assess their difficulty and accuracy. Two canine cadavers were used to establish the techniques and eight cadavers to assess difficulty and accuracy. Contrast medium was injected and a CT scan was performed after each injection. Accuracy was assessed according to epidural or joint space contrast opacification. Difficulty was classified as easy, moderately difficult, or difficult, based on the number of CT scans needed to guide insertion of the needle. A total of six translaminar and five transforaminal epidural and 53 joint injections were performed. Translaminar injections had a high success rate (100%), were highly accurate (75%), and easy to perform (100%). Transforaminal injections had an moderately high success rate (75%), were accurate (75%), and moderately difficult to perform (100%). Success rate of facet joint injections was 62% and was higher for larger facet joints, such as L7-S1. Accuracy of facet joint injections ranged from accurate (37-62%) to highly accurate (25%) depending on the volume injected. In 77% of cases, injections were moderately difficult to perform. Possible complications of epidural and facet joint injections were subarachnoid and vertebral venous plexus puncture and periarticular spread, respectively. Further studies are suggested to evaluate in vivo feasibility and safety of these techniques.
