OBJECTIVE: We collected the radiographic and medical knowledge of 129 AIS sufferers (Lenke sort 1-6) to research the traits of cervical sagittal alignment in adolescent idiopathic scoliosis sufferers and the correlations between cervical sagittal alignment and world sagittal alignment, and medical signs.
METHODS: 129 sufferers with AIS and 48 adolescent volunteers had been included on this examine. The angles of the principle thoracic curve, proximal thoracic curve, thoracolumbar curve, lumbar curve, C2-7 Cobb angle, T5-12 Cobb angle, L1-5 Cobb angle, pelvic incidence, pelvic tilt, sacrum slop, C2-7 sagittal vertical axis, C7-S1 sagittal vertical axis, and T1 pelvic angle had been included in radiographic measurements. As well as, a 10-cm Visible Analogue Rating was used to evaluate neck ache. Pearson correlation coefficients and t-test had been used for statistical evaluation.
RESULTS: Within the AIS group, C2-7 Cobb angle elevated considerably in contrast with the management group, and it was considerably correlated with T5-12 Cobb angle and L1-5 Cobb angle. There was no vital correlation between C2-7 Cobb angle and coronal curvature in every Lenke sort of sufferers. Within the C2-7 SVA ? three cm group, C2-7 Cobb angle was associated to T5-12 Cobb angle, L1-5 Cobb angle, pelvic incidence, and sacrum slop. Within the cervical kyphosis group, T5-12 Cobb angle was considerably decrease than that of the C2-7 Cobb angle ?zero group. The C2-7 Cobb angle within the group with T5-12 Cobb angle >30° elevated considerably in contrast with that within the group with T5-12 Cobb angle ?30°. The Visible Analogue Rating of neck ache of the cervical imbalance group was considerably greater than that of the cervical steadiness group.
CONCLUSIONS: The cervical sagittal alignment in AIS sufferers was associated with thoracic kyphosis and lumbar lordosis, particularly with thoracic kyphosis, however not with the coronal angle of thoracic and lumbar backbone, and pelvic parameters.
