Prevalence of Intra-spinal Pathologies in Adolescent Idiopathic Scoliosis Patients
Journal Title: Journal of Academic Research in Medicine - Year 2020, Vol 10, Issue 1
Abstract
Objective: To evaluate the prevalence of intra-spinal pathologies (ISP) in adolescent idiopathic scoliosis patients. Methods: We retrospectively reviewed all adolescent idiopathic scoliosis cases surgically treated in our institution between 2012 and 2015. Patients aged less than 10 years and older than 20 years were excluded, in addition to those with no hospital records of pre-operative magnetic resonance imaging (MRI) scans or abnormal neurological examination findings. Patients who underwent revision surgery were also excluded. An experienced spinal surgeon measured curvature magnitudes in the coronal plane and thoracic kyphosis angles using the Cobb method, and a radiologist evaluated the MRI scans. The patients were then divided into an ISP group and non-ISP group and compared. Results: After applying the exclusion criteria, 124 patients with adolescent idiopathic scoliosis were included in the study. Ten (8%) patients had ISP. Eight patients had syringomyelia in the thoracic region, one had a Chiari malformation with syringomyelia, and one had a tethered cord. There were no statistically significant differences between the groups in terms of age, sex, magnitude of thoracic kyphosis angle, magnitude of major coronal curve or direction of the main curve in patients with AIS (p>0.05). Of the 10 patients, two with ISP, one with a tethered cord and one with a Chiari malformation required additional neurosurgical procedures prior to corrective surgery. Conclusion: The prevalence of ISPs in AIS patients was 8%. Given the risk of neurological complications, we recommend that MRI should be routinely performed in all adolescent idiopathic scoliosis patients scheduled for corrective surgery.
