Injection drug use is associated with repeat irrigation and debridement in native joint septic arthritis.

Background And Objective: Septic arthritis is an orthopaedic emergency that requires prompt irrigation and debridement (I&D). Some patients require a repeat I&D, which poses excessive burden on the patient and provider. The goal of this study was to identify possible risk factors for repeat I&D in the setting of native septic arthritis.

Validation of Examination Maneuvers for Adolescent Idiopathic Scoliosis in the Telehealth Setting.

Background: Telehealth visits (THVs) have made it essential to adopt innovative ways to evaluate patients virtually. This study validates a novel THV approach that uses educational videos and an instructional datasheet, enabling parents to use smartphones to measure their child's scoliosis at home or in telehealth settings.

Methods: We identified a prospective cohort of patients with adolescent idiopathic scoliosis (AIS) scheduled for follow-up care from March to July 2021.

Polymerization of Epoxides at a Static Oil-Alkaline Water Interface.

'On-water' catalysis entails the significant enhancement of a chemical reaction by water, even when those reactions are known to be water-sensitive. Here, the findings about the anionic ring opening polymerization of epoxides at the static interface between oil and alkaline water are shared. Unexpectedly, high molar mass fractions are observed with the interfacial system presented herein, albeit at very low conversions (< 5%).

The Longitudinal Effects of Posterior Spinal Fusion with Derotation on Axial Deformity in Adolescent Idiopathic Scoliosis.

Study Design: Retrospective case series.

Objective: To characterize the change in angle of trunk rotation (ATR), axial vertebral rotation (AVR), and body surface rotation (BSR) in patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion (PSF) with en-bloc derotation across multiple postoperative visits.

Summary Of Background Data: Previous research has documented ATR, AVR, and BSR correction for AIS patients after surgery.

Analysis of 5,070 consecutive pedicle screws placed utilizing robotically assisted surgical navigation in 334 patients by experienced pediatric spine deformity surgeons: surgical safety and early perioperative complications in pediatric posterior spinal fusion.

Purpose: This study evaluates the intraoperative and short-term complications associated with robotically assisted pedicle screw placement in pediatric posterior spinal fusion (PSF) from three surgeons at two different institutions.

Methods: We retrospectively reviewed 334 pediatric patients who underwent PSF with robotic-assisted navigation at 2 institutions over 3 years (2020-2022). Five thousand seventy robotically placed screws were evaluated.
