Limb Lengthening for Congenital Deficiencies Using External Fixation Combined With Flexible Intramedullary Nailing: A Multicenter Study.
Hydroxyapatite (HA) coated flexible intramedullary nailing (FIN) stimulates osteogenic activity. The role of HA-coated intramedullary nails remains unclear in normal bone lengthening. The goal of this study was to quantify the influence of FIN on the External Fixation Index (EFI) in patients with congenital lower limb discrepancy. ⋯ Both Ti-nail and HA-coated nail lengthening provide good and excellent outcomes for femoral and tibial monosegmental lengthening procedures and ensure reduced EFI. In congenital disorders which were not associated with abnormal bone, there are no differences with regard to EFI using HA-coated or non-HA-coated FIN. The ratio of "elastic Ti-nail diameter/medullary canal diameter at narrowest site" <0.15 seems to be associated with higher risk of fracture at the lengthening site after frame removal.

Universal Screening for COVID-19 in Children Undergoing Orthopaedic Surgery: A Multicenter Report.
The COVID-19 pandemic has substantially altered the typical process around performing surgery to ensure protection of health care workers, patients, and their families. One safety precaution has been the implementation of universal preoperative screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study examines the results of universal screening on children undergoing orthopaedic surgery. ⋯ Level II.

The Reliability of the AOSpine Thoracolumbar Classification System in Children: Results of a Multicenter Study.
The purpose of this study was to determine whether the new AOSpine thoracolumbar spine injury classification system is reliable and reproducible when applied to the pediatric population. ⋯ Level III.

Intraobserver and Interobserver Reliability of the Oberg-Manske-Tonkin (OMT) Classification: Establishing a Registry on Congenital Upper Limb Differences.
The purpose of this investigation was to determine the reliability of the Oberg-Manske-Tonkin (OMT) classification system applied to patients enrolled in a prospective, multicenter cohort study of congenital upper limb differences. Our hypothesis was that the OMT classification would exhibit high intraobserver and interobserver reliability and thus would be an appropriate tool for the new Congenital Upper Limb Differences registry. ⋯ Level II-diagnostic.

Adolescent Idiopathic Scoliosis Thoracic Volume Modeling: The Effect of Surgical Correction.
Scoliosis has been shown to have detrimental effects on pulmonary function, traditionally measured by pulmonary function tests, which is theorized to be correlated to the distortion of the spine and thorax. The changes in thoracic volume with surgical correction have not been well quantified. This study seeks to define the effect of surgical correction on thoracic volume in patients with adolescent idiopathic scoliosis. ⋯ Level 3-retrospective comparison of prospectively collected data.
