  • Spontaneous remodeling of the Spinal Canal after conservative management of thoracolumbar burst fractures
    Spine, 1998
    Co-Authors: Luuk W. L. De Klerk, W. Peter J. Fontijne, Theo Stijnen, Reiner Braakman, Herve L. J. Tanghe, Bert Van Linge
    Abstract:

    STUDY DESIGN Forty-two conservatively treated patients with a burst fracture of the thoracic, thoracolumbar, or lumbar spine with more than 25% stenosis of the Spinal Canal were reviewed more than 1 year after injury to investigate spontaneous remodeling of the Spinal Canal. OBJECTIVES To investigate the natural development of the changes in the Spinal Canal after thoracolumbar burst fractures. SUMMARY OF THE BACKGROUND DATA Surgical removal of bony fragments from the Spinal Canal may restore the shape of the Spinal Canal after burst fractures. However, it was reported that restoration of the Spinal Canal does not affect the extent of neurologic recovery. METHODS Using computerized tomography, the authors compared the least sagittal diameter of the Spinal Canal at the time of injury with the least sagittal diameter at the follow-up examination. RESULTS Remodeling and reconstitution of the Spinal Canal takes place within the first 12 months after injury. The mean percentage of the sagittal diameter of the Spinal Canal was 50% of the normal diameter (50% stenosis) at the time of the fracture and 75% of the normal diameter (25% stenosis) at the follow-up examination. The correlation was positive between the increase in the sagittal diameter of the Spinal Canal and the initial percentage stenosis. There was a negative correlation between the increase in the sagittal diameter of the Spinal Canal and age at time of injury. Remodeling of the Spinal Canal was not influenced by the presence of a neurologic deficit. CONCLUSION Conservative management of thoracolumbar burst fractures is followed by a marked degree of spontaneous redevelopment of the deformed Spinal Canal. Therefore, this study provides a new argument in favor of the conservative management of thoracolumbar burst fractures.

  • MR determination of neonatal Spinal Canal depth.
    European journal of radiology, 2012

    Abstract:

    Abstract Objectives Lumbar punctures (LPs) are frequently performed in neonates and often result in traumatic haemorrhagic taps. Knowledge of the distance from the skin to the middle of the Spinal Canal (mid-Spinal Canal depth – MSCD) may reduce the incidence of traumatic taps, but there is little data in extremely premature or low birth weight neonates. Here, we determined the Spinal Canal depth at post-mortem in perinatal deaths using magnetic resonance imaging (MRI). Patients and methods Spinal Canal depth was measured in 78 post-mortem foetuses and perinatal cases (mean gestation 26 weeks; mean weight 1.04 kg) at the L3/L4 inter-vertebral space at post-mortem MRI. Both anterior (ASCD) and posterior (PSCD) Spinal Canal depth were measured; MSCD was calculated and modelled against weight and gestational age. Results ASCD and PSCD (mm) correlated significantly with weight and gestational age (all r > 0.8). A simple linear model MSCD (mm) = 3 × Weight (kg) + 5 was the best fit, identifying an SCD value within the correct range for 87.2% (68/78) (95% CI (78.0, 92.9%)) cases. Gestational age did not add significantly to the predictive value of the model. Conclusion There is a significant correlation between MSCD and body weight at post-mortem MRI in foetuses and perinatal deaths. If this association holds in preterm neonates, use of the formula MSCD (mm) = 3 × Weight (kg) + 5 could result in fewer traumatic LPs in this population.

  • ultrasonographic determination of neonatal Spinal Canal depth
    Archives of Disease in Childhood-fetal and Neonatal Edition, 2008
    Co-Authors: Owen J Arthurs, Matthew Murray, Mustafa Zubier, James Tooley, Wilf Kelsall
    Abstract:

    Objective: To determine by ultrasound (US) the Spinal Canal depth (SCD) in neonates and subsequently establish a nomogram and simple formula for calculating this distance. Design: 116 US measurements were performed by two investigators in 105 neonates at the L3/4 intervertebral space. Both anterior and posterior Spinal Canal depth were measured and mid-Spinal Canal depth (MSCD) calculated. Measurements of intra- and interobserver variability were also performed. Results: A clear relationship was found between body weight (W, kg) and all SCD measurements in neonates. In particular, MSCD  =  2.2W + 6.89 mm ( R 2 correlation coefficient 0.76), approximated by 2W + 7 mm. Conclusion: SCD measurements are easily determined by US in neonates, with good correlation between weight and MSCD.

  • Vertebral hemangioma. Spontaneous Spinal Canal remodeling after fracture.
    Spine, 1994
    Co-Authors: Philippe Menei, Alah Richeh, Thierry Favier, Philippe Mercier, Gilles Guy
    Abstract:

    STUDY DESIGN The patient in this report had a fracture of a hemangiomatous vertebra with a fragment protruded into the Canal and without neurological signs. There was a 12 month follow-up. RESULTS After conservative treatment, there were no neurologic signs, a good fusion, and natural remodeling of the Spinal Canal. CONCLUSIONS The risk of a hemangiomatous vertebra fracture with a fragment retropulsed into the Spinal Canal and without neurologic signs is low. Also, a remodeling of the Spinal Canal can occur, as after a burst fracture.
