Intraspinal anomalies in scoliosis: An MRI analysis of 177 consecutive scoliosis patients.

摘要: Background : The association of intraspinal neural anomalies with scoliosis is known for more than six decades. However, there are no studies documenting the incidence in scoliotic patients Indian population. guide lines to obtain an magnetic resonance imaging (MRI) scan rule out neuro-axial abnormalities presumed adolescent idiopathic also not clear. We conducted a prospective study (a) document and analyze types different patients. (b) identify clinico-radiological 'indicators' that best predict findings scoliosis, which will alert physician possible presence optimize use MRI this sub group Materials Methods data from 177 consecutive aged less 21 years were analyzed. Patients categorized into three groups; Group A - congenital (n=60), B -presumed (n=94) C secondary neurofibromatosis, neuromuscular connective tissue disorders (n=23). type anomaly was correlated patient symptoms, clinical signs curve characteristics. Results 35% (21/60), tethered cord due filum terminale being commonest (10/21). multiple vertebral had highest (48%) isolated hemi vertebrae none. In 'idiopathic' higher (16%) previously reported. Arnold Chiari-I malformation (AC-I) syringomyelia most common (9/15) neurological (100%), apical kyphosis (66.6%) early onset scoliosis. Isolated lumbar curves anomalies. group-C, 22% disorders. Conclusion high our emphasizes need detailed examination subtle accompany Preoperative screening recommended who present at young age, thoracic kyphosis.
