Purpose: To biomechanically assess the influence of intraoperative correction and presenting Sanders maturity scores (SS) on growth modulation correction after 2 years in pediatric idiopathic scoliosis treated with Vertebral Body Tethering (VBT).
Methods: Lumbar VBT was simulated using patient-specific finite element models (FEMs) from 20 cases of pediatric idiopathic scoliosis (average thoracolumbar/lumbar Cobb 47°; min: 34°, max: 63°), calibrated for preoperative SS, weight, and spine flexibility. The validated FEM included lateral decubitus positioning and VBT instrumentation at the actual upper instrumented vertebra (UIV: T9-T12) and lower instrumented vertebra (LIV: L2-L4).

Purpose: The relationship between skeletal maturity and postoperative growth modulation (GM) in patients treated with Vertebral Body Tethering (VBT) is poorly understood. We aimed to: (1) identify preoperative skeletal maturity factors associated with GM, and (2) assess the relationship between GM and postoperative success in patients treated with VBT.
Methods: We retrospectively reviewed radiographic data from 55 patients with a minimum follow-up of 2 years (2.
Background: Adolescent idiopathic scoliosis (AIS) is the most common spinal deformity among children. Although posterior spinal fusion (PSF) is a commonly used treatment for curves ≥ 45°, anterior vertebral body tethering (VBT) has recently gained traction as an alternative for some patients. Surgeons have established radiographic definitions of success for PSF, with similar efforts underway for VBT.

With this study, we aim to evaluate the postoperative outcomes in boys versus girls who have undergone VBT. Our hypothesis is that girls and boys will have similar outcomes by 2-year follow-up.

Background: Vertebral body tethering (VBT) is a well-recognized, non-fusion alternative for idiopathic scoliosis in children with growth remaining. To date, there have been almost no published outcome studies with postoperative follow-up of >2 years. We aimed to fill this gap by evaluating mid-term outcomes in our first 31 consecutive patients.

Vertebral body tethering (VBT) is a fusionless alternative. Shoulder balance is an important metric for outcomes and patient satisfaction.

Background: Supracondylar humerus fractures (SCHFs) are the most common elbow fracture in the pediatric population. In the case of displaced fractures, closed reduction and percutaneous Kirschner wire pinning (CRPP) is commonly performed. Infection rates are between 0 and 7%; however, retrospective studies have shown no benefit of preoperative antibiotics.

We aim to compare the radiographic outcomes between VBT and PSF in patients with double curvatures in which both curves were instrumented.

Background: Thoracic anterior vertebral body tethering (TAVBT) is an emerging treatment for adolescent idiopathic scoliosis. Tether breakage is a known complication of TAVBT with incompletely known incidence. We aim to define the incidence of tether breakage in patients with adolescent idiopathic scoliosis who undergo TAVBT.

The anterior instrumentation was occluding her right basilar bronchus, resulting in hyperinflation. Removal of the instrumentation reversed the hyperinflation.

This 52-week phase 2 (ACcomplisH) trial assessed the safety and efficacy of TransCon CNP in children with achondroplasia.
Methods: ACcomplisH is a global, randomised, double-blind, placebo-controlled, dose-escalation trial.
Purpose: Although several studies have reported on the application of biplanar stereo-radiographic technology in pediatric clinical practice, few have performed large-scale analyses. The manual extraction of these types of data is time-consuming, which often precludes physicians and scientists from effectively utilizing these valuable measurements. To fill the critical gap between clinical assessments and large-scale evidence-based research, we have addressed one of the primary hurdles in using data derived from these types of imaging modalities in pediatric clinical practice by developing an application to automatically transcribe and aggregate three-dimensional measurements in a manner that facilitates statistical analyses.

This study identifies socio-economic characteristics, surgical characteristics, and patient reported psychological factors influencing postoperative opioid use in this population and found that post-operative opioid use in this pediatric orthopaedic population is multifactorial. Physicians should consider implementing protocols for initial opioid prescriptions to cover two to three days following common orthopaedic surgeries for most pediatric patients.

The present study utilized a large, multicenter database and propensity matching to compare outcomes of AVBT to PSF in patients with idiopathic scoliosis.
Methods: Patients with thoracic idiopathic scoliosis who underwent AVBT with a minimum 2-year follow-up retrospectively underwent 2 methods of propensity-guided matching to PSF patients from an idiopathic scoliosis registry.
Purpose: The use of vertebral body tethering (VBT) for the treatment of main thoracic deformities in adolescent idiopathic scoliosis patients is becoming increasingly more common, but limited data exist on its safety and efficacy in thoracolumbar deformities. We aimed to evaluate the postoperative outcomes of patients with thoracolumbar (TL) deformities that were treated with VBT.
Methods: We assessed clinical and radiographic data from twenty-eight consecutive patients that were surgically managed with VBT, all of whom exhibited a TL deformity with at least two years (mean: 44.
Purpose: Little is known about the perioperative characteristics associated with a posterior spinal fusion (PSF) in adolescent idiopathic scoliosis patients previously treated with vertebral body tethering (VBT). We aimed to determine if operative time, estimated blood loss, postoperative length of stay, instrumentation type, and implant density differed in patients that received a PSF (i.e.

Purpose: The purpose of the study was to evaluate the effect of skeletal age and lesion size, location, and grade on the success of nonoperative treatment for juvenile osteochondritis dissecans (OCD). It is hypothesized that skeletal maturity, including a combination of maturation phenotypes, correlates with nonoperative lesion healing.
Methods: The clinical and radiographic data on 52 patients aged 7-20 years treated for OCD of the distal femur between 2010 and 2019 were retrospectively reviewed.
Purpose: This study was undertaken to collect baseline growth parameters in children with achondroplasia who might enroll in interventional trials of vosoritide, and to establish a historical control.
Methods: In this prospective, observational study, participants (≤17 years) underwent a detailed medical history and physical examination and were followed every 3 months until they finished participating in the study by enrolling in an interventional trial or withdrawing.
Results: A total of 363 children were enrolled (28 centers, 8 countries).
All eleven-year-old girls want to do is play and be active like every other child her age. Yet, the ability to have a normal childhood for one of our patients became a concern when she and her parents noticed an abnormal lateral curvature in her spine, which was later diagnosed as adolescent idiopathic scoliosis. In February 2014, she presented with a 45° thoracic deformity with a high risk of progression.

Introduction: Posterior spinal fusion (PSF) is the gold standard procedure for curve correction in Adolescent Idiopathic Scoliosis (AIS). Enhanced recovery protocols (ERPs) have been found to decrease pain and hospital length of stay (LOS) resulting in decreased total hospital charges.
Methods: We identified all adolescent idiopathic scoliosis patients treated with a posterior spinal fusion at our children's hospital between 2015-2019.

Background: Growth modulation through anterior vertebral body tethering (AVBT) has emerged as a fusionless option for the treatment of progressive scoliosis. When tethering the main thoracic curve, the compensatory thoracolumbar/lumbar curve must correct indirectly as a result. The present study evaluated the response of these lumbar curves following AVBT of the main thoracic curves.
