Abstract
Surgical correction of spinal deformity in patients with neural axis abnormalities has established risks of causing further neurological injury. It is necessary to identify individuals with a predisposition for such abnormalities before treatment is instituted.
Objective: Examination of the association between idiopathic scoliosis and underlying neural axis abnormalities in the infantile and juvenile age groups.
Design: Retrospective chart and radiographic review.
Subjects: Ninety-four (36 infantile, 58 juvenile) consecutive patients with non-congenital scoliosis under the age of eleven years.
Outcome measures: These consisted of the MRI findings, neurological examination, associated curve morphology and necessity for neurosurgical intervention or surgical curve correction.
Results: Approximately 25% of patients presenting as idiopathic juvenile scoliosis had underlying neural axis abnormalities. No patient with apparent infantile idiopathic scoliosis had an abnormal spinal MRI scan. Using the Z score for independent proportions, there was a statistically significant difference between infantile and juvenile scoliosis and the presence of an underlying neural axis abnormality (Z score of 2.089, equivalent to p< 0.02).
Conclusions: We advocate routine MR spinal imaging in all patients with juvenile idiopathic scoliosis. In infantile idiopathic scoliosis, to avoid unnecessary general anaesthetics, one should image the spinal canal only when clinically indicated
