Lumbar spine duplication: a case report
Duplication of the spine is a rare malformation. A neurologically intact pediatric patient with this malformation is described here. A 6-year-old girl presented to our institution for evaluation of an asymptomatic kyphotic deformity. She denied weakness, sensory changes, and bowel or bladder complaints. Physical examination revealed mild kyphosis at the thoracolumbar junction with normal gait and neurologic function. Radiographs demonstrated duplication of the lumbar spine and sacrum. Computed tomography, MRI, and abdominal ultrasound results are reported. As she is neurologically normal, we will continue to observe this patient and intervene in the case of development of neurologic impairment or worsening kyphosis.
Spondylocostal dysostosis is a rare genetic disease characterized by skeletal malformations, such as multiple segmentation defects of the vertebrae, rib misalignment with variable points of intercostal fusion, and reduction in the number of ribs. In the literature, we did not find any reports of oral manifestations related to this condition. This is the report of a 23-year-old white woman with spondylocostal dysostosis, with short stature, short trunk and neck, prominent thorax, moderate scoliosis, umbilical hernia, and cognitive deficit.
For half her life, Martha Hunt, 30, has lived with chronic pain, she told DailyMail.com. The model has scoliosis, a curvature of the spine that makes long shoots painful - but copes through writing.
With great interest, we have recently read the article titled “Outcomes of patients with syringomyelia undergoing spine deformity surgery: do large syrinxes behave differently from small?” by Samdani et al. . The authors retrospectively reviewed 28 syringomyelia-associated scoliosis patients (11 with large syrinx [LS,>4 mm] and 17 with small syrinx [SS,
CONCLUSION: a-SS was strongly correlated with PI. The correlation between a-SS and LL was equivalent to the correlation between PI and LL. Moreover, the ICC for a-SS was larger than that of PI. This study suggests that a-SS is a useful new pelvic anatomical parameter that can be used instead of PI. PMID: 31829115 [PubMed - in process]
AbstractIntroductionThe Gait Deviation Index (GDI) is a composite measure of gait abnormality derived from lower-limb joint range-of-motion which is increasingly being reported for clinical gait analysis among neurologic and orthopedic patients. A GDI score of 100 is representative of healthy individuals and decreasing scores represent a greater abnormality. Preliminary data is needed to help assess the utility of GDI as a measure of compromised gait among spine patients and to provide reference values for commonly treated pathologies.MethodsGDI scores were obtained from healthy adults and four symptomatic degeneration gro...
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.
CONCLUSIONS: In 1- and 2-level ACDF with plating involving the same number of fusion levels, there was no statistically significant difference in the pseudarthrosis rate, revision surgery rate, subsidence, and lordosis loss between PEEK cages and structural allograft.

ConclusionsCSVA, T1 slope and T1 –CL are good predictors of postoperative degenerative kyphotic change and neck pain. Careful consideration of their preoperative cutoff values can improve postoperative outcomes.Level of evidenceIV.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

AbstractPurposeThe study is aimed to investigate the expression ofPAX3 in bilateral paravertebral muscles in adolescent idiopathic scoliosis (AIS) and controls, and to further clarify its association with the paravertebral muscle volume and curve severity.MethodsTen AIS patients and 10 age-matched controls with lumbar disc herniation were included. Bilateral biopsies of paravertebral muscles were obtained at the apical vertebral level for patients and at L5 level for controls. The concave and convex expression ofPAX3 was compared between the two groups. The AIS patients were evaluated with magnetic resonance imaging scan o...
