Multiple techniques exist to reconstruct the scapholunate interosseous ligament, though none have demonstrated superiority. This study compares 1-year radiographic outcomes of the three-ligament tenodesis and the anatomical front and back reconstruction. All patients who underwent reconstruction of their scapholunate interosseous ligament at one institution with either anatomical front and back reconstruction or three-ligament tenodesis between 2011 and 2020 were retrospectively reviewed. At 52-week follow-up, anatomical front and back reconstruction maintained a statistically significant improvement in scapholunate gap, corrected radiolunate angle and dorsal scaphoid translation, while three-ligament tenodesis demonstrated no sustained improvement in any parameter. The improvement in dorsal scaphoid translation was significantly greater for patients undergoing anatomical front and back reconstruction compared with three-ligament tenodesis at the 16-weeks postoperative timepoint (−1.0 mm, −0.3 mm). Anatomical front and back reconstruction demonstrates sustained improvement in radiographic outcomes at 1 year when compared with three-ligament tenodesis. By addressing both volar and dorsal critical ligament restraints, adoption of anatomical front and back reconstruction for advanced stage scapholunate interosseous ligament injuries should be considered.

The improvement in dorsal scaphoid translation was significantly greater for patients undergoing anatomical front and back reconstruction compared with three-ligament tenodesis at the 16-weeks postoperative timepoint (-1.0 mm, -0.3 mm). Anatomical front and back reconstruction demonstrates sustained improvement in radiographic outcomes at 1 year when compared with three-ligament tenodesis. By addressing both volar and dorsal critical ligament restraints, adoption of anatomical front and back reconstruction for advanced stage scapholunate interosseous ligament injuries should be considered.

Electric scooter (e-scooter) use and resulting injuries have grown exponentially since expansion into ridesharing in 2017. No study has described pediatric e-scooter injuries and focused on their impact in an adolescent cohort. Our primary purpose was to describe the epidemiology of admitted pediatric e-scooter injuries and compare them with existing literature on adults. We queried the National Electronic Injury Surveillance System for e-scooter injuries between 2015 and 2019 in patients 0-18 years old. Injuries caused by an e-scooter to a nonrider were removed. Patients admitted to the hospital were analyzed and weighted national estimates were calculated. A P value of <0.05 was considered significant. Nine hundred and two pediatric patients were treated for an e-scooter injury at an emergency department (ED) between 2015 and 2019. Among those admitted (n = 47), 72.3% were men, and the average age at injury was 11.3 years. Among all injuries (n = 56), the most common diagnosis was fracture (24/56, 42.9%). The 19% (9/47) of patients that experienced polytrauma were significantly older than those with single injuries (P < 0.001). ED admissions grew by 616% from 2017 to 2018. Children experience a greater rate of fractures and polytrauma from e-scooters compared to adults, but fewer facial injuries despite a similar rate of head trauma. The incidence of pediatric head injuries indicates a lack of helmet use similar to adults. Lawmakers should consider bolstering e-scooter regulations to decrease pediatric injuries., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)
