“…Cases of spinal cord rotation have also been published previously in the literature. [10][11][12][13][14] Various causes have been reported, including congenital malformation of the cord itself, epidural lipomatosis, and spinal deformity-induced rotation, as presented in this report. 10,12,14 In cases of deformity-induced cord rotation, the degree of rotation has been correlated to Cobb angle.…”

“…10,12,14 In cases of deformity-induced cord rotation, the degree of rotation has been correlated to Cobb angle. 12,13 Previously, the highest degree of rotation published appears to have been 90° rotation within the thecal sac due to epidural lipomatosis. 11 The present report, however, suggests a cord rotated significantly more than 90° with thecal sac torsion, which could be the largest angle of torsion for spinal cord rotation in the published literature.…”

“…11 The present report, however, suggests a cord rotated significantly more than 90° with thecal sac torsion, which could be the largest angle of torsion for spinal cord rotation in the published literature. [10][11][12][13][14] Degree of rotation, in addition to its effects on the neurological function of the cord, could have important implications for complications such as C5 nerve palsy following surgery, but this area requires further investigation due to the paucity of reports. 15 Various radiographic measures have been used to evaluate spinal cord rotation utilizing MRI, CT myelography, and spinal angiography.…”

“…15 Various radiographic measures have been used to evaluate spinal cord rotation utilizing MRI, CT myelography, and spinal angiography. [12][13][14] The high level of curvature and kyphotic deformity with subarachnoid space compression prevented rotational measurement using any of these previously described measuring systems. Regardless, intraoperative findings suggest greater than 90° of torsion, which correlates well with associations between higher Cobb angles and increased spinal cord rotation.…”

This report describes a 42-year-old man who presented with an α-type spinal deformity with a Cobb angle of 224.9° and associated spinal cord rotation greater than 90°. Preoperative imaging revealed extensive spinal deformity, and 3D modeling confirmed the α-type nature of his deformity. Intraoperative photography demonstrated spinal cord rotation greater than 90°, which likely contributed to the patient’s poor neurological status. Reports of patients with Cobb angles ≥ 100° are rare, and to the authors’ knowledge, there have been no published cases of adult α-type spinal deformity. Furthermore, very few cases or case series of spinal cord rotation have been published previously, with no single patient having rotation greater than 90° to the authors’ knowledge. Given these two rarities presenting in the same patient, this report can provide important insights into the operative management of this difficult form of spinal deformity.

The use of MRI in the study of patients with idiopathic scoliosis: a systematic review of the literature

Objective. To analyze the frequency of hidden neuraxial pathology in idiopathic scoliosis (IS), to substantiate the need for MRI in IS and to identify promising areas for the use of MRI in the examination of patients with IS.Material and Methods. The literature review was carried out using the PubMed and Google Scholar databases. Of the 780 papers on the research topic, 65 were selected after removing duplicates and checking for inclusion/exclusion criteria. As a result, 49 original studies were included in the analysis. Level of evidence – II.Results. According to modern literature, the main direction of using MRI in idiopathic scoliosis is the search for predictors of latent pathology of the spinal cord and craniovertebral junction. The frequency of neuraxial pathology in idiopathic scoliosis is 8 % for adolescent IS and 16 % for early IS. The main predictors of neuraxial pathology are male sex, early age of deformity onset, left-sided thoracic curve and thoracic hyperkyphosis. MRI in IS may be a useful addition to radiological diagnostic methods to identify risk factors and to study degenerative changes in the spine.Conclusion. MRI of the spine should be performed in the early stages of IS to detect latent spinal cord tethering. In type I Chiari anomalies, there is a possibility that early neurosurgery can prevent the development of scoliosis. The main signs of latent neuraxial pathology in IS are early progression of spinal deformity, left-sided thoracic curve, male gender and thoracic kyphosis over 40° according to Cobb.MRI can be used as an effective non-invasive tool in research aimed at identifying risk factors for IS, including helping to track early degeneration of intervertebral discs.

Asynchronous neuro-osseous growth in adolescent idiopathic scoliosis—MRI-based research

2010

View full text Add to dashboard Cite

Adolescent idiopathic scoliosis (AIS) is a common worldwide problem and has been treated for many decades; however, there still remain uncertain areas about this disorder. Its involvement and impact on different parts of the human body remain underestimated due to lack of technology in imaging for objective assessment in the past. The advances in imaging technique and image analysis technology have provided a novel approach for the understanding of the phenotypic presentation of neuro-osseous changes in AIS patients as compared with normal controls. This review is the summary of morphological assessment of the skeletal and nervous systems in girls with AIS based on MRI. Girls with AIS are found to have morphological differences in multiple areas including the vertebral column, spinal cord, skull and brain when compared with age- and sex-matched normal controls. Taken together, the abnormalities in the skeletal system and nervous system of AIS are likely to be inter-related and reflect a systemic process of asynchronous neuro-osseous growth. The current knowledge about the anatomical changes in AIS has important implications with respect to the understanding of fundamental pathomechanical processes involved in the evolution of the scoliotic deformity.
