Multicenter Study
Vertebral artery injury associated with blunt cervical spine trauma: a multivariate regression analysis.
Retrospective analysis of prospective registry data. ⋯ VAI associated with blunt cervical spine injury is a marker for more severely injured patients. High-risk patients with basilar skull fractures, occipitocervical dissociation, fracture displacement into the transverse foramen more than 1 mm, ankylosing spondylitis/diffuse idiopathic skeletal hyperosteosis, and facet subluxation/dislocation deserve focused consideration for VAI screening.

Selective thoracic fusion in Lenke 1C curves: prevalence and criteria.
Multicenter retrospective analysis of prospectively collected data. ⋯ 3.

Systematic review. ⋯ Based on a combination of excellent and good quality studies, transverse area correlates with recovery ratio but not with postoperative functional score assessed by Japanese Orthopaedic Association/modified Japanese Orthopaedic Association scores. SI changes defined by (1) its presence on T2WI, (2) its extent (focal or multisegmental), (3) its brightness, and (4) its presence on both T1-/T2WI can predict surgical outcomes in degenerative compressive myelopathy.

Systematic review. ⋯ Despite high fusion rates there is a growing body of evidence that the use of BMP in PLIF and TLIF constructs does not come without potential complication. There are appreciable rates of BMP-specific complications, which include heterotopic ossification within the epidural space or neuroforamina, postoperative radiculitis, and endplate osteolysis with interbody device subsidence.

Multicenter Study
Clinically significant differences exist between curves in operative idiopathic early-onset scoliosis and adolescent idiopathic scoliosis.
Retrospective analysis. ⋯ Significant radiographical differences exist between operative IEOS and AIS curves. IEOS curves are greater in magnitude, more kyphotic, less well compensated, and have a more caudal apex and stable vertebra. These findings suggest that younger patients may require more distal instrumentation and that proximal fixation techniques should consider the additional pullout forces created by the greater kyphosis.
