Comparative Study
Reconstruction of large iliac crest defects after graft harvest using autogenous rib graft: a prospective controlled study.
Prospective controlled study analyzing the donor site morbidity after reconstruction of full thickness iliac crest defects, using autologous rib grafts. ⋯ Rib graft reconstruction provides a cheap and effective alternative for iliac crest reconstruction. Patients undergoing thoracotomy or thoraco-phrenico-lumbotomy for spinal reconstruction, the unutilized rib graft should be used to reconstruct the iliac defect. Reduced donor site morbidity and better cosmesis are the major benefits of reconstruction.

Retrospective review of adolescent idiopathic scoliosis (AIS) patients. ⋯ Two Lenke 1A curve patterns can be described based on the direction of the L4 tilt. This distinction has ramifications regarding selection of fusion levels and assessing surgical outcomes. The A and B lumbar modifiers do not describe 2 distinct curve types within the Lenke 1 group; however, the tilt direction of L4 does allow subdivision of the Lenke 1A curves into 2 distinguishable patterns (1A-R and 1A-L). The 1A-L curves are similar to 1B curves and different in form and treatment from the 1A-R pattern.

Case series. ⋯ Apical convex rib head dislocation into the canal in NF-1 scoliotic patients can be suspected by conventional radiograms and be proven by CT and MRI. The rib dislocation is not a contraindication to deformity correction with modern spinal instrumentation techniques when preventive measures are applied.

A retrospective study to review patients with acute thoracolumbar burst fractures who were conservatively treated. ⋯ Conservative treatment is safe and effective for selected patients with thoracolumbar burst fractures, even in some cases with neurologic deficit. The Load Sharing Classification could be used for guiding the treatment of thoracolumbar burst fractures not only in surgical approach choice but also in surgical decision-making.

Retrospective analysis using kinetic magnetic resonance images (MRIs). ⋯ The present study demonstrated that the changes in sagittal alignment of the cervical spine affect the kinematics. Consequently, it may cause changes in the segment subjected to maximum load for overall motion and accelerate its degeneration.
