What factors predict cervical sagittal alignment restoration after correction of thoracic adolescent idiopathic scoliosis with severe thoracic hypokyphosis? A multicenter retrospective study of 57 patients.

Purpose: to evaluate changes in cervical sagittal alignment after correction of AIS with severe thoracic hypokyphosis (< 10°); to assess radiographical parameters predicting postoperative cervical sagittal alignment through multivariate regression analysis.

Methods: A multicenter retrospective study included AIS patients with severe thoracic hypokyphosis. Treatment involved posterior spinal fusion with pedicle screws, Ponte osteotomies, differential rod contouring and DVR.

Factors Related to Proximal Junctional Kyphosis and Device Failure in Patients with Early-Onset Scoliosis Treated with a Traditional Dual Growing Rod: A Single Institution Study.

Study Design: Observational study.

Purpose: Investigation of factors related to proximal junctional kyphosis (PJK) and device failure in patients with early-onset scoliosis.

Overview Of Literature: The use of growth-friendly devices, such as traditional dual growing rod (TDGR) for the treatment of earlyonset scoliosis (EOS), may be associated with important complications, including PJK and device failure.

The effect of cage type on local and total cervical lordosis restoration and global spine alignment in single-level anterior cervical discectomy and fusion based on EOS imaging: A comparison between standalone conventional interbody polyether ether ketone cage and integrated cage and plate (Perfect-C).

Background: There is a small level of evidence regarding the alterations in global spine alignment following the restoration of cervical lordosis using anterior cervical discectomy and fusion (ACDF). Different cage types are available to restore cervical lordosis through ACDF. In this study, we evaluate the impact of two types of these cages on local and global spine alignments.
