Spine deformity

Biomechanical analysis of proximal junctional kyphosis (PJK) through numerical simulations. ⋯ Simulated posteriorly shifted sagittal alignment was associated with higher PJK risks, whereas extending instrumentation proximally allowed a lower mechanical risk of PJK. Preserving PJ intervertebral elements and using a more flexible anchorage at UIV help reduce the biomechanical risks of PJK.

Retrospective comparative study. ⋯ The standard EOS imaging system moderately reduced the total radiation exposure to skeletally immature scoliosis patients. Over the entire treatment course, this represented 2.72 mSv mean reduction or 0.91 years of background radiation. Posteroanterior films significantly reduced breast and thyroid dose.

Single-center, prospective, randomized, double-blinded trial. ⋯ Compared with Amicar, TXA use was associated with a lower allogenic transfusion requirement, less alteration in postoperative clotting studies, and a trend toward lower blood loss in pediatric posterior spinal fusion patients.

Program director survey. ⋯ This study examined the opinions of orthopedic and neurological surgery residency and spine fellowship PDs regarding current spine surgery training in the United States. A large majority of PDs thought that both orthopedic and neurological surgical trainees should complete a fellowship if they plan to perform spinal deformity surgery. These results provide a background for further efforts to optimize contemporary spine surgical training.
