Under the headline "Correlation of RANKL concentrations and VDR-FokI polymorphism on disc herniation" in the description text for Table 2, the term "allelic frequency" was used erroneously for "genotypic frequency".

Review Meta Analysis
Does image guidance decrease pedicle screw-related complications in surgical treatment of adolescent idiopathic scoliosis: a systematic review update and meta-analysis.
Surgical treatment of severe adolescent idiopathic scoliosis (AIS) with posterior spinal instrumentation and fusion with pedicle screws is common, requiring careful screw insertion to prevent pedicle breaches and neurologic complications. Image guidance has been suggested to improve breach rates, though the radiation risk for AIS precludes its common usage. The purpose of this systematic review and meta-analysis was to compare the breach rates and screw-related complications for AIS patients undergoing spine surgery with pedicle screws between freehand screw insertion and image guidance methods. ⋯ Meta-analyzed breach rates show moderate evidence of decreased breaches with CT navigation compared with freehand methods. Complication rates remain unknown due to the low complication rates from small sample sizes. These slides can be retrieved under Electronic Supplementary Material.

Distal radius and ulna (DRU) classification scheme has been proposed for predicting skeletal maturity in patients with idiopathic scoliosis (IS). However, the utilization of DRU classification scheme in the assessment of growth peak and curve progression in IS was still inconclusive. This study aimed to correlate the distal radius and ulna stages with several indicators for growth potential and to evaluate the predictive value of DRU system for curve progression in braced female IS patients. ⋯ Both distal radius and ulna scores correlate with the longitudinal growth potential, and thus, the DRU scoring scheme is an alternative predictor for growth potential and curve progression in girls with IS.

Multicenter Study Observational Study
Preoperative SRS pain score is the primary predictor of postoperative pain after surgery for adolescent idiopathic scoliosis: an observational retrospective study of pain outcomes from a registry of 1744 patients with a mean follow-up of 3.4 years.
Traditionally, adolescent idiopathic scoliosis (AIS) has not been associated with back pain, but the increasing literature has linked varying factors between pain and AIS and suggested that it is likely underreported. ⋯ 12% of all AIS patients who underwent fusion had back pain after postoperative recovery. The most consistent predictive factor of increased postoperative pain across all curve types was a low preoperative SRS pain score.
