Multicenter Study
Identification of decision criteria for revision surgery among patients with proximal junctional failure after surgical treatment of spinal deformity.
Multicenter, retrospective, consecutive case series. ⋯ The decision to perform revision surgery is complicated and varies by surgeon. Factors that seem to influence this decision include traumatic etiology of PJF, severity of proximal junctional kyphosis angulation, higher SVA, and female sex. Factors that were expected to influence revision but had no statistical effect included soft tissue versus bony mode of failure, age, levels fused, and upper thoracic versus thoracolumbar proximal junction.

Randomized Controlled Trial
A randomized prospective evaluation of 3 techniques of postoperative pain management after posterior spinal instrumentation and fusion.
Randomized prospective trial. ⋯ These data document that the double CEA most effectively controls postoperative pain after surgery for AIS. The single CEA trended toward having the fewest side effects when compared with the other techniques. On the basis these findings, we now routinely use the double CEA technique for all patients having surgery for AIS.

Case Reports
Multiple abscesses with osteomyelitis and destruction of both the atlas and the axis in a 4-week-old infant.
Case report. ⋯ C1-C2 osteomyelitis is a very rare entity even in children. There is limited experience with treatment, but immobilization of the neck, surgical debridement, drainage, and antibiotic treatment can be recommended. Close follow-up is required to check the reconstitution of affected bones and ligaments, any development of instability, and the necessity of surgical stabilization.

Follow-up of animals after surgically initiated scoliosis. ⋯ This study establishes a rat lumbar scoliosis model via asymmetric load. This method develops lumbar scoliosis in a short time and maintains the essential elements along the curve. It is suitable for the investigation of scoliosis.

Basic science rodent model of bone morphogenetic protein-2 (BMP-2) soft-tissue inflammation. ⋯ Low-dose DM administration is effective in controlling the cellular inflammation and edema resulting from BMP-2. Ten or 15 mg of DM might be considered by spine surgeons for controlling the inflammation and edema seen in spine surgery with BMP-2.
