MINI: Proximal junctional kyphosis (PJK) is a common, yet incompletely understood, complication of surgery for adult spinal deformity. We analyzed 440 consecutive adult spinal deformity patients for trends in development of PJK and need for revision surgery. pelvic tilt and thoracic kyphosis were predictive for developing PJK, while radiographic evidence of proximal junctional failure was predictive for proceeding to revision.

Multi-Level 3D Printing Implant For Reconstructing Cervical Spine With Metastatic Papillary Thyroid Carcinoma.
MINI: A 3D printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma. The personalized porous implant printed in Ti6AL4V provided excellent physicochemical properties and biological performance, including biocompatibility, osteogenic activity, and bone ingrowth effect. ⋯ 5.

MINI: A modified selective anesthetics delivery rabbit model was used validated to a better preferential anesthesia than previous models. Furthermore, we found evidence that primarily the spinal cord mediated the skeletal muscle relaxation action of sevoflurane.

MINI: Posterior hemivertebra resection with anterior structural reconstruction and short segmental fusion may be a reliable procedure for selected patients with scoliokyphosis due to a hemivertebra, providing good correction both on the coronal and sagittal planes, saving mobile segments with lower risk of implants failures. ⋯ 4.

Biography Historical Article
Louis A. Goldstein MD: A Pioneer in Spinal Deformity Surgery.
MINI: During the first half of the 20th century interest in spinal deformity grew due to common conditions of that era including polio and tuberculosis. This article will discuss Louis Arnold Goldstein, a visionary leader in spinal deformity surgery from Rochester, New York and one of the founders of the Scoliosis Research Society. During the first half of the 20th century interest in spinal deformity grew due to common conditions of that era including polio and tuberculosis. ⋯ Louis A. Goldstein was a talented surgeon, administrator, and clinician scientist. He also started a spine surgery fellowship program that still bears his name and that continues to train complex spine surgeons.
