“…Although easy to recognise and well-defined diagnostic criteria were used to recognise thoracic vertebral body malformations, spinal kyphosis and spinal scoliosis, little is known on how both imaging modalities compare for these specific purposes. Several studies in human medicine have compared radiography vs. CT [ 31 , 32 ] and radiography vs. MRI [ 33 , 34 ] to evaluate and quantify spinal curvature abnormalities, while only a few studies have compared all three imaging techniques for this purpose [ 35 , 36 ]. The results of these studies indicate that CT and MRI can be used to evaluate and quantify spinal curvature abnormalities with a good reliability, correlation and agreement among the three imaging techniques.…”

BackgroundAlthough thoracic vertebral malformations with kyphosis and scoliosis are often considered incidental findings on diagnostic imaging studies of screw-tailed brachycephalic breeds, they have been suggested to interfere with spinal biomechanics and intervertebral disc degeneration. It is however unknown if an abnormal spinal curvature also predisposes dogs to develop clinically relevant intervertebral disc herniations. The aim of this study was to evaluate if the occurrence of thoracic vertebral malformations, kyphosis or scoliosis would be associated with a higher prevalence of cervical or thoracolumbar intervertebral disc extrusion in French bulldogs.ResultsFrench bulldogs that underwent computed tomography for reasons unrelated to spinal disease (n = 101), and French bulldogs with thoracolumbar (n = 47) or cervical intervertebral disc extrusion (n = 30) that underwent magnetic resonance imaging were included. There was a significant association between the presence of kyphosis and the occurrence of intervertebral disc extrusion, particularly in the thoracolumbar region. Dogs with kyphosis were at nearly a two times increased odds of being affected by intervertebral disc extrusion than those without kyphosis [(OR = 1.98 (95% CI: 1.04–3.78)]. There was also an association between the presence of scoliosis and the anatomical distribution of intervertebral disc extrusions, with dogs with scoliosis more likely to have more caudal lumbar intervertebral disc extrusions. Presence of scoliosis was not associated with an increased odds of being affected by intervertebral disc extrusion.ConclusionsAlthough thoracic vertebral malformations with kyphosis only rarely cause spinal cord dysfunction in itself, French bulldogs with kyphosis appear to be at higher risk to develop thoracolumbar intervertebral disc extrusion.Electronic supplementary materialThe online version of this article (doi: 10.1186/s12917-017-1316-9) contains supplementary material, which is available to authorized users.

“…2 The major disadvantage of radiographic films is their inability to detect ligamentous injuries. 38 Measurement of posttraumatic kyphotic angulation is useful for assessment of fracture progression, especially for fractures managed conservatively. Kyphotic angulation is measured as the angle between the superior end plate one level above and the inferior end plate one level below the injured segment.…”

“…CT is ideal for imaging complex fractures and determining the degree of vertebral comminution. 38 More complex imaging modalities, such as CT myelography and magnetic resonance imaging (MRI) are not necessary unless the patient has a neurologic deficit. In special cases where the compression fracture is because of an infectious or malignant process, more advanced MRI techniques can be used.…”

“…When the patient is lying down during an MRI examination, the patient's back muscles can be completely relaxed, and the protective anteversion brought on by discomfort can also be reduced. Due to the short examination time, these factors cannot be completely eliminated in CT examination [22]. Kaiser R et al [23] found a linear dependency between hyperextension radiograph and MRI exibility with a mean difference of 9.3° (R 2 = 0.61, p < 0.001) by using the imaging data of 18 Scheuermann kyphosis patients.…”

Objective This study aimed to investigate whether preoperative magnetic resonance imaging (MRI) can be used for sagittal kyphotic (SK) flexibility assessment in patients with kyphosis secondary to symptomatic old osteoporotic thoracolumbar fracture (so-OTLF). Methods The authors evaluated the radiographic data of patients with kyphosis secondary to so-OTLF. All patients underwent posterior corrective fusion surgery in the hospital. Spinal sagittal parameters were measured on standing radiographs preoperatively. The regional kyphosis angle (RKA) was also measured on preoperative supine MRI and intraoperative prone radiographs on the surgical frame. The SK flexibility in patients with kyphosis secondary to so-OTLF was defined as the difference between the RKA measured on the standing radiographs and that measured on the intraoperative prone radiographs or preoperative supine MRI. The difference and the correlation between the SK flexibility measured by these two methods were compared and analyzed. Results Thirty-seven patients were included. The RKA measured on standing radiographs, supine MRI, and intraoperative prone radiographs were 48.03°, 34.40°, and 31.95°, respectively. Compared with the RKA measured in standing position, the RKA measured on supine MRI decreased by 13.63° (95% confidence interval 11.44°– 15.82°), whereas that measured on intraoperative prone radiographs decreased by 16.08° (95% confidence interval 13.66°–18.50°). A linear correlation existed between the SK flexibility measured on supine MRI and that measured on intraoperative prone radiographs, with a mean difference of 2.44° (R2 = 0.912, p<0.001). Conclusion The degree of regional kyphosis deformity was reduced by self-reduction of the intraoperative surgical frame. With a predictive value similar to an intraoperative prone radiograph, preoperative supine MRI can be used for SK flexibility assessment in patients with kyphosis secondary to so-OTLF. The ability to predict the intraoperative degree of regional kyphosis deformity with positioning before an operation helps with surgical planning and patient counseling regarding expectations and risks of surgery.
