The L4-5 space should be avoided since it is the center of the lumbosacral intumescence in most dogs. Tanaka H, Nakayama M, Takase K. Usefulness of myelography with multiple views in diagnosis of circumferential location of disc material in dogs with thoracolumbar intervertebral disc herniation. Platt SR, McConnell J, Bestbier M. Magnetic resonance imaging characteristics of ascending hemorrhagic myelomalacia in a dog. Front Vet Sci. Mild local enhancement of the meninges or epidural material after IV administration of gadolinium-based contrast has been reported (154), though this is usually not present (147, 150). Another key point to minimize the risk of seizures is the use of lumbar injections, since the risk of seizure was seven times higher with cerebellomedulary cistern injections in both studies (55, 56). Herrera JJ, Chacko T, Narayana PA. Histological correlation of diffusion tensor imaging metrics in experimental spinal cord injury. Vet Clin North Am Small Anim Pract. Screen for long term stability of the spine. One study identified four MRI variables that could be considered independent predictors of thoracolumbar IVDE vs. IVDP (Figure 8) (132): Midline instead of lateralized intervertebral disc herniation was associated with a diagnosis of IVDP, Partial instead of complete loss of the hyperintense signal of the nucleus pulposus was associated with a diagnosis of IVDP, The presence of a single intervertebral disc herniation instead of multiple intervertebral disc herniations was associated with IVDE. Acta Vet Scand. Epidural fat surrounds the thecal sac and is less dense than soft tissue, so it appears darker gray. Ventral, lateral and dorsal spinal cord compressions are noted at L1-2. In order to assist with this differentiation, criteria have been proposed and are discussed in the IVDP section below. I am looking to purchase a French Bulldog, he is a dwarf being 8 wks and 2 lbs will probably only get to be 10 lbs in full adult life. 84. (A) T2-weighted sagittal and (B) BALT GRAD (T2-weighted thin-slice gradient echo) transverse MR images of an 8-year old Greyhound with an L2-L3 IIVDE. (1994) 66:25967. Until two decades ago, myelography was probably the most commonly used imaging modality to diagnose spinal conditions in veterinary medicine (16). The reliability of sagittal T2-weighted (T2W) images alone for the determination of compressive disc lesions was determined to range from 81.4 to 89.0%. Signs of related disease, however, must be diagnosed by employing more sophisticated imaging studies to demonstrate that compression of the spinal cord is taking place as a result of the vertebrae. Yeamans CL, Haley A, Gutierrez-Quintana R, Penderis J. Surgical anatomical landmarks of the thoracolumbar vertebral column on magnetic resonance imaging in dogs. Olby N, Levine J, Harris T, Munana K, Skeen T, Sharp N. Long-term functional outcome of dogs with severe injuries of the thoracolumbar spinal cord: 87 cases (1996-2001).

Each case is individual and an experienced spinal surgeon is needed to perform stabilization. Lewis MJ, Early PJ, Mariani CL, Munana KR, Olby NJ. The deformity of the vertebrae will lead to a twisting of the spine which can compress your dogs spinal cord. This 10% difference was also seen when MRI was prospectively compared to myelography (30). Am J Vet Res. Non-ionic, iodinated, water-soluble contrast agents such as iohexol, iopamiron, or iotrolan, with concentrations ranging from 180 to 240 mg/ml, ideally at body temperature, should be used (42).

It has been suggested that visualization of extradural leakage, suggestive of a dural tear, can be improved by applying traction to the head (166). (1994) 35:3516. J Am Vet Med Assoc. Myelography addresses some of the constraints of survey radiographs but has largely been supplanted by cross-sectional imaging. (2016) 57:41726. While radiographs can provide useful information, especially for identifying intervertebral disc degeneration or calcification, there are notable limitations. Influence of duration of injury on diffusion tensor imaging in acute canine spinal cord injury. (2003) 229:3743. Ames, IA: Wiley (2015). doi: 10.1002/jsp2.1011, 92. Konar M, Lang J.

Myelography vs. computed tomography in the evaluation of acute thoracolumbar intervertebral disk extrusion in chondrodystrophic dogs. (D) Sagittal T1W image. It is based on a system for grading gross pathological changes in IVDs proposed by Thompson et al., which is the most commonly used criterion-referenced standard in human medicine (88). (2010) 52:24. doi: 10.1186/1751-0147-52-24, 30. Suran JN, Durham A, Mai W, Seiler GS. Regards Dr Callum Turner DVM Since the spinal cord itself cannot be directly visualized on plain CT, spinal cord compression in both groups of dogs was inferred from loss of the hypoattenuating epidural space. Kinematic magnetic resonance imaging for evaluation of disc-associated cervical spondylomyelopathy in doberman pinschers. Jeffery ND, Harcourt-Brown TR, Barker AK, Levine JM. J Vet Intern Med Proc ACVIM Forum. doi: 10.1016/j.cvsm.2017.08.004, 146. Presence of residual material following mini-hemilaminectomy in dogs with thoracolumbar intervertebral disc extrusion. It is worth mentioning that IVDP can be lateralized in both cervical and thoracolumbar regions. Future studies in canine IVDH should be considered to assess their clinical and translational utility in this population. Prog Vet Neurol. Front Vet Sci. The hip joint is a ball and socket joint with the ball (femoral head) being on the proximal end of the thigh bone (femur) and the socket (acetabulum) being on the pelvis. doi: 10.1111/j.1740-8261.2010.01734.x, 112. Vet J. Reynolds D, Brisson BA, Nykamp SG. WB Saunders Co., Toronto. There is a small volume of extradural material dorsal to the affected intervertebral disc space, with minimal to no spinal cord compression. doi: 10.2460/javma.248.9.1013, 160. In 1952, Hansen classified IVDD into acute, or Hansen type I intervertebral disc extrusion (IVDE), and chronic, or Hansen type II intervertebral disc protrusion (IVDP) (4). (2018) 32:198995. Vet Radiol Ultrasound. Affected animals typically present with a peracute onset of possibly strongly lateralized clinical signs, often during strenuous exercise or trauma. The value of oblique versus ventrodorsal myelographic views for lesion lateralisation in canine thoracolumbar disc disease. It was also in the 2000s that magnetic resonance imaging (MRI) and computed tomography (CT) started to become routinely used in referral hospitals. Acta Vet Scand. This mass effect caused by the extruded material causes compression and/or displacement of the spinal cord, seen on T2W images as displacement or loss of the hyperintense signal associated with subarachnoid and epidural spaces. Acute non-compressive nucleus pulposus extrusion is characterized by a sudden extrusion of non- or minimally degenerative nucleus pulposus without residual spinal cord compression. doi: 10.1136/vr.130.14.296, 36. The dorsal plane can be very useful in these instances since the ribs and transverse processes can be easily identified. With only minor symptoms treating the symptoms conservatively with crate rest anti-inflammatories will likely be recommended. Somerville ME, Anderson SM, Gill PJ, Kantrowitz BJ, Stowater JL. J Am Anim Hosp Assoc. With the acetabulum this is achieved by the three bones that make up one side of the pelvis (ilium, ischium and pubis) joining at the acetabulum thus forming a complex pattern of growth zones. doi: 10.1111/j.1752-1688.1977.tb02007.x, 34. doi: 10.1016/j.spinee.2012.12.003, 94. (2013) 26:128. Gelatin sponges can also be easily differentiated from residual disc material based on their sharply demarcated shape and hyperintensity on T2W images (120). Diagnosis of hemivertebrae is made by taking simple X-rays. Lancourt JE, Glenn WV Jr, Wiltse LL. The homogenously hyperintense nucleus pulposus has a reduced volume and the intervertebral disc space is narrowed. The normal intervertebral disc is of uniform soft tissue opacity in CT images, with no visible distinction between the nucleus pulposus and annulus fibrosus (63). Rates and discounts vary, are determined by many factors, and are subject to change. Advantages of CT relative to MRI include that it is more widely available, less costly and much faster. Based on the small number of current studies, the utility of DTI and tractography to quantify injury severity and predict prognosis remains unclear. On the health certificate, it states "5 coccyx vertabae (tail) are present. Vet Comp Orthop Traumatol. Gellad F, Rao KC, Joseph PM, Vigorito RD. Hemivertebrae of the tail are not a problem as there is no spinal cord tissue this far down and the result is an interesting-looking tail with possibly a skin fold infection risk. Histopathology typically does not reveal specific abnormalities and the underlying pathomechanism might be related to ischemia, muscle spasm or denervation edema (112). To eliminate bad backs (and to a lesser extent at this age - hips) from breeding programs and to prevent severe abnormalities from being on-sold to the general public. Vet Rec. Bos AS, Brisson BA, Nykamp SG, Poma R, Foster RA. The site of injection site should be the ventral subarachnoid space at L5-6 (ideally). Magn Reson Med.

The reported sensitivity for lateral localization ranges from 49 to 83%, although the precision can be greatly improved with the combination of ventrodorsal and oblique views (15, 17, 30, 37, 45, 53, 54). Cervical spondylomyelopathy (Wobbler syndrome) in dogs. Hydrated nucleus pulposus extrusion (HNPE) is characterized by sudden extrusion of minimally to non-degenerative nucleus pulposus. J Neurotrauma. Vet Surg. (C) Transverse T2W image at the L5-6 level showing lateralized spinal cord compression and spinal cord hyperintensity. Cervical hyperesthesia is not commonly observed. (2017) 38:15362. Due to upfront and maintenance costs, low-field (0.20.4 T) units currently greatly outnumber high-field ones, primarily in private referral practices (73). Since MRI has become more widely available in veterinary medicine, additional types of IVDH have been recognized, which are characterized by sudden herniation of non-degenerative or minimally degenerative nucleus pulposus.
