Abstract Purpose The complex three-dimensional spinal deformity in AIS consists of rotated, lordotic apical areas and neutral junctional zones that modify the spine’s sagittal profile. Recently, three specific patterns of thoracic sagittal ‘malalignment’ were described for severe AIS. The aim of this study is to define whether specific patterns of pathological sagittal alignment are already present in mild AIS. Methods Lateral spinal radiographs of 192 mild (10°–20°) and 253 severe (> 45°) AIS patients and 156 controls were derived from an international consortium. Kyphosis characteristics (T4–T12 thoracic kyphosis, T10–L2 angle, C7 slope, location of the apex of kyphosis and of the inflection point) and sagittal curve types according to Abelin-Genevois were systematically compared between the three cohorts. Results Even in mild thoracic AIS, already 49% of the curves presented sagittal malalignment, mostly thoracic hypokyphosis, whereas only 13% of the (thoraco) lumbar curves and 6% of the nonscoliosis adolescents were hypokyphotic. In severe AIS, 63% had a sagittal malalignment. Hypokyphosis + thoracolumbar kyphosis occurred more frequently in high-PI and primary lumbar curves, whereas cervicothoracic kyphosis occurred more in double thoracic curves. Conclusions Pathological sagittal patterns are often already present in curves 10°–20°, whereas those are rare in non-scoliotic adolescents. This suggests that sagittal ‘malalignment’ patterns are an integral part of the early pathogenesis of AIS.

Abstract Background: To evaluate the short to mid-term radiographic and clinical outcomes of the restoration of normal spinal alignment and sagittal balance in the treatment of Kümmell’s disease with thoracolumbar kyphosis. Methods: Between February 2016 and May 2018,30 cases of Kümmell’s disease with thoracolumbar kyphosis were divided into two groups (A and B) according to whether the kyphosis was combined with neurological deficits.All of the cases underwent surgical treatment to regain the normal spinal alignment and sagittal balance.And the radiographic outcomes and clinical results of these 30 patients were retrospectively evaluated.The sagittal imaging parameters including sagittal vertebral axis (SVA),thoracic kyphosis (TK),thoracolumbar kyphosis (TLK),lumbar lordosis (LL),pelvic incidence (PI),pelvic tilt (PT),and sacral slope (SS)of the whole spine before operation,immediately after operation,and the last follow-up of each group were measured and evaluated.The clinical results included the Oswestry Disability Index (ODI) and the Numerical Rating Scale (NRS) of the two groups .Results: The average follow-up period of group A and B were 34.2 and 38.7 months respectively.The parameters of both groups such as SVA,TLK,and thoracolumbar Cobb angle after surgery and at the last follow-up were significantly improved compared with those before surgery.The ODI and the NRS of the two groups at the last follow-up were also significantly improved. Conclusion: In the treatment of Kümmell’s disease with thoracolumbar kyphosis,to restore the normal alignment and sagittal balance can obtain a satisfactory radiographic and clinical short and medium-term effects.
