MINI: Pressure injuries are prevalent in patients undergoing spine surgery while prone. Multiple risk factors exist and should be addressed. We found that patients undergoing spinal deformity correction surgery are at unique risk (odds ratio 3.31, P = 0.010) due to body morphological changes occurring secondary to intraoperative changes in spinal alignment. ⋯ 3.

MINI: The authors wanted to determine which existing primary-care low back pain stratification schema is associated with distinct subpopulations. Initial stratification by DMPP identified potentially distinct epidemiological groups. DMPP stratification resulted in discrimination beyond that provided by disability or chronicity risk stratification alone.

MINI: Intraoperative cell salvage (ICS) is used to reduce blood loss in scoliosis spinal fusion. We report one case of hemolysis induced acute renal failure following ICS. This is the first reported case of acute renal failure associated with hemolysis following ICS in a scoliosis patient with sickle cell trait.

MINI: The objective of this study was to evaluate the accuracy and reliability of pedicle screw placement using O-Arm at dosages below the manufactured recommended dose. O-Arm at reduced dose showed a 90% accuracy when compared with computed tomography; however, about 30% medial breaches were misclassified.

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.
