Understanding Respiratory Restrictions as a Function of the Scoliotic Spinal Curve in Thoracic Insufficiency Syndrome: A 4D Dynamic MR Imaging Study

Conclusions: The relationships between component tidal volumes and the spinal curve type are complex and are beyond intuitive reasoning and guessing. TLC has a much greater influence on restricting chest wall and diaphragm tidal volumes than MTC. Major curve angles are not indicative of passive resting volumes or tidal volumes. Level of Evidence: Level II—diagnostic.

ConclusionCurve progression can be predicted by the underlying vertebral abnormalities. However, it cannot predict cord and other organ-system anomalies. Thus, all patients with congenital scoliosis must undergo MRI of the spine, electro- and echocardiography and ultrasonography of the abdomen to detect occult abnormalities and optimize the patient prior to deformity correction.

Conclusion. Dextrocardia shows increased incidence of AIS in both male and female patients. Left-sided thoracic curvature in cases with concurrent dextrocardia may not be associated with intra-spinal pathology as seen in the general population. These data suggest that thoracic organ orientation affects AIS convexity directionality. Level of Evidence: 3

Conclusions: Even with the absence of subjective urinary symptoms, subclinical urologic impairments can be observed in a significant number of patients with ISC. An abnormal UDS finding can be a sign of underlying spinal cord tethering in a patient with ISC who is a candidate for corrective spine surgery even though it is an independent variant and is not exclusive to candidates for surgery. This finding has high clinical utility for neuro- and ortho-spine surgeons who aim to correct scoliosis (OR, 4.2; p =0.009). PMID: 32066207 [PubMed - as supplied by publisher]

We describe a comprehensive, multidisciplinary treatment approach for lumbar vertebral hemangiomas (VHs) with spinal stenosis and radiculopathy. A 59-year-old female presented with 1 year of pain predominantly in the lower back, with pain in the left buttock and proximal left anterior thigh as well and magnetic resonance imaging of the lumbar spine demonstrated lumbar scoliosis and an L3 vertebral lesion suspicious for hemangioma. A computed tomography guided biopsy was done, which supported the diagnosis. Definitive treatment entailed preoperative angiography and embolization, followed by L3 laminectomy, right L3 pedicle ...

Conclusion: The 3D finite element model based on 3D finite element software was highly efficient, and its numerical simulation was accurate, which was important for the subsequent biomechanical analysis of PVCR orthopaedy. In addition, the vertebral stress of PVCR orthopaedy was different in each body part, which was mainly affected by the applied orthodontic force and the sites of the orthodontic area.

ConclusionThis is the first study in IIS patients to identify a radiographic parameter that helps select out a subgroup for MRI screening. Additionally, we report an incidence of 24.5% NAAs in these patients, which is higher than previously reported.

Authors: Dehnokhalaji M, Golbakhsh MR, Siavashi B, Talebian P, Javidmehr S, Bozorgmanesh M Abstract Study Design: Retrospective study. Purpose: Lumbar intervertebral disc degeneration is an important cause of low back pain. Overview of Literature: Spinal fusion is often reported to have a good course for adolescent idiopathic scoliosis (AIS). However, many studies have reported that adjacent segment degeneration is accelerated after lumbar spinal fusion. Radiography is a simple method used to evaluate the orientation of the vertebral column. magnetic resonance imaging (MRI) is the method most often used to ...

CONCLUSIONS: There is a larger degree of lateral deviation of the LP on the concave side of scoliosis compared to medial deviation on the convex side. These deviations remained consistent irrespective of the direction of scoliosis. A review of the imaging studies and pre procedural ultrasound assessment of anatomy should be strongly considered prior to needle puncture. In patients with severe DS, an alternative approach may be considered to avoid the possibility of visceral organ injury. PMID: 30035457 [PubMed - as supplied by publisher]

Discussion VATER association was first described in the 1970s with additional congenital malformations being added to the association so it is most often called VACTERL association. It is a highly heterogeneous, overlapping condition estimated to occur in ~1/10,000-40,000 births. The cause is unknown. In animal models, some signaling pathway gene mutations have phenotypes of VACTERL association. Experts suggest that patients having at least 2 components should be further evaluated (at least 3 for diagnosis) for VACTERL and other diseases in its differential diagnosis. There are more than 30 syndromes, mutations and diseas...

ConclusionThis study analyzed MRI using texture information of muscle to distinguish flexible from rigid scoliotic curves. Some postural muscle such as the spinal erector and the psoas major are more likely to reflect the curve flexibility of a scoliotic participant.Level of Evidence: 2Technical Efficacy: Stage 1J. Magn.
