“…Sexual dimorphism was one of the significant features of IS, and considered to be related to the etiopathogenesis of AIS. In AIS patients who received surgeries, the ratio of female to male could reach 10:1, whereas in scoliotic patients with neural axis abnormalities, this dimorphism is not so significant [9,10,21]. Loder et al [26] compared the difference of gender distribution between patients of Chiari 1 malformation and AIS patients, demonstrating that the group of Chiari 1 malformation had a higher proportion of males than AIS group (37 vs. 8 %, P \ 0.01).…”

“…Magnetic resonance imaging (MRI) seems to be a good modality that could clearly illustrate neural axis abnormalities with the advantages of better visualization of soft tissues and absence of radiation. However, the routine use of MRI is controversial, and the indications for MRI in presumed ''idiopathic'' scoliosis vary from study to study [7][8][9][10]. Many predictive factors, including curve pattern, age, gender, radiographic parameters and the presence of abnormal findings on the history or physical examination have been proposed when deciding whether or not to image the neural axis in patients with presumed ''idiopathic'' scoliosis [4][5][6][7][8].…”

“…The subgroup of IIS has been found to have rates of 13 to 50 % and JIS to have rates between 14 and 27 % [1, 2,[4][5][6][7]. In the only British study to date, a non-standard age range (four to 12 years of age) representing a combination of juvenile and adolescent onset scoliosis was used and a 26 % rate of spinal abnormalities was found.…”

Purpose Rates of neural axis abnormalities in infantile and juvenile idiopathic scoliosis may be as high as 50 %. We aimed to determine the rates of neural axis abnormalities in early onset idiopathic scoliosis patients in a British population. Methods This retrospective study at two British spinal deformity clinics identified 72 patients satisfying the inclusion criteria of: (1) age at diagnosis of 7 years and younger, (2) idiopathic scoliosis and (3) magnetic resonance imaging of the neuraxis. Results The mean age at diagnosis was 3.6 years and the mean Cobb angle was 47°with a near equal distribution of left (32) and right (36) sided curves. Eight (11.1 %) neural axis abnormalities consisting of two syrinxes, one Arnoldchiari Type I malformation and five combined (Arnold-chiari malformation Type I and syrinx) anomalies were identified. Conclusions This multi-centre study on the largest number of British subjects to date helps to establish the rates of neural axis abnormalities.

Are there magnetic resonance imaging‐detectable pathologies in idiopathic scoliosis patients?

Scoliosis may be a spinal manifestation of underlying disease, therefore, imaging plays a very important role in determining the underlying aetiology of so‐called ‘idiopathic’ scoliosis. If underlying intraspinal defects go unrecognised and untreated, irreversible neurological deficit can develop. Magnetic resonance imaging (MRI) is the modality of choice for imaging the spinal canal, albeit controversially. This literature review has been designed to find out whether there are associated MRI‐detectable pathologies in idiopathic scoliosis patients. If so, what is the incidence of such abnormalities? And when would MRI evaluations be warranted for idiopathic scoliosis patients? Twenty studies relating to MRI and scoliosis met the criteria and were used to perform a meta‐analysis. The majority of the articles took the view that a non‐invasive investigation which does not use ionising radiation and which can reliably exclude such intraspinal occult disease should not be withheld. Results showed that, in a population of 1398 idiopathic scoliosis patients, MRI detected 226 (16%) related intraspinal pathologies. The most common pathologies were 73 syringomyelias (32%) and 44 Chiari malformations (19%). In conclusion, until further investigation is conducted into the clinical significance of the intraspinal diseases with idiopathic scoliosis, whole spine MRI evaluations with a variety of imaging planes and pulse sequences are warranted in all idiopathic scoliosis patients, even if it is from a defensive risk management viewpoint.
