            Scoliosis patients with osteogenesis imperfect have deformities in the sagittal plane; increased thoracic kyphosis and lumbar lordosis decreased, accompanied by abnormalities of the craniocervical junction according gravity. To determine the sagittal alignment espinopelvico and evaluation of craniocervical junction. Retrospective of 5 patients with osteogenésis imperfect compared with 10 patients with juvenile idiopathic scoliosis healthier, image review. 15 patients were evaluated; the mean age was 10 years, 9 cases of male and 6 female. Comparing the angular parameters showed increased thoracic kyphosis in patients with Osteogenesis (T1 and T2). No compensation between thoracic kyphosis and lumbar lordosis, positive displacement of the sagittal T1 line and T9.Se found similar correlations were observed between lumbar lordosis (L1-L5 and L1-S1) and dens trend was observed to approach the base of the skull and platybasia. In patients with osteogenésis thoracic kyphosis T1-T4 was higher in the upper chest than in the control group, we suggest that may be responsible for worsening vertebral deformities with lung involvement and sagittal imbalance of the trunk. More complex studies are needed to pinpoint the exact location of the most frequently affected vertebrae, determinant for better stabilization and alignment of the trunk and early evaluation of the craniocervical junction to prevent further neurological factor.

Key Words: Osteogenesis Imperfect, espinopelvico sagittal balance, craniocervical junction.
