Current trends and perspectives of scoliosis research society travel fellows.

Purpose: This study aims to measure the impact of the Scoliosis Research Society's travel fellowship on a spinal surgeon's career.

Methods: A non-incentivized survey was sent to 78 previous SRS junior travel fellows from 1993 to 2021. The questionnaire assessed fellowship influence on academic and administrative positions, professional society memberships, and commercial relationships.

Analysis of three-dimensional spine growth for vertebral body tethering patients at 2 and 5 years post operatively.

Purpose: Scoliosis can be treated with vertebral body tethering (VBT) as a motion-sparing procedure. However, the knowledge of how growth is affected by a tether spanning multiple levels is unclear in the literature. Three-dimensional true spine length (3D-TSL) is a validated assessment technique that accounts for the shape of the spine in both the coronal and sagittal planes.

Coronal decompensation following thoracic vertebral body tethering in idiopathic scoliosis.

Purpose: Post-operative coronal decompensation (CD) continues to be a challenge in the treatment of adolescent idiopathic scoliosis (AIS). CD following selective spinal fusion has been studied. However, there is currently little information regarding CD following Vertebral Body Tethering (VBT).

3D Gait Analysis and Patient-reported Outcomes of Femoral Osteotomies for Torsional Deformity.

Background: Idiopathic torsional deformities causing pain and/or functional difficulty is an indication for a femoral derotational osteotomy (FDRO). Past studies have focused entirely on children with internal femoral torsional deformity (IFTD). This study aims to compare gait and outcomes between children with IFTD and those with external femoral torsional deformity (EFTD) after a FDRO.

Knee Recurvatum in Children With Spastic Diplegic Cerebral Palsy.

Background: The purpose of this study is to determine which factors drive patients with diplegic cerebral palsy to walk without knee recurvatum despite hyperextension of the knee on physical examination.

Methods: A retrospective review was conducted of all data collected in the Gait Analysis Laboratory between 1999 and 2014. Patients with spastic diplegic cerebral palsy and at least 5 degrees of knee extension on clinical examination were identified for the study.

The Influence of the Unaffected Hip on Gait Kinematics in Patients With Hemiplegic Cerebral Palsy.

Background: Hemiplegic cerebral palsy (HCP) patients have transverse-plane gait deviations that may include the "uninvolved" side. The aim of this study is to quantify the static rotational profile, the dynamic position during gait and determine whether any correlations between the involved and uninvolved side exist.

Methods: A total of 171 subjects that met the inclusion criteria of HCP and no prior history of bony surgery were reviewed.

Unique Footprint in the scl1.3 Locus Affects Adhesion and Biofilm Formation of the Invasive M3-Type Group A Streptococcus.

The streptococcal collagen-like proteins 1 and 2 (Scl1 and Scl2) are major surface adhesins that are ubiquitous among group A Streptococcus (GAS). Invasive M3-type strains, however, have evolved two unique conserved features in the scl1 locus: (i) an IS1548 element insertion in the scl1 promoter region and (ii) a nonsense mutation within the scl1 coding sequence. The scl1 transcript is drastically reduced in M3-type GAS, contrasting with a high transcription level of scl1 allele in invasive M1-type GAS.

Maturation and experience in action representation: Bilateral deficits in unilateral congenital amelia.

Congenital unilateral absence of the hand (amelia) completely deprives individuals of sensorimotor experiences with their absent effector. The consequences of such deprivation on motor planning abilities are poorly understood. Fourteen patients and matched controls performed two grip selection tasks: 1) overt grip selection (OGS), in which they used their intact hand to grasp a three-dimensional object that appeared in different orientations using the most natural (under-or over-hand) precision grip, and 2) prospective grip selection (PGS), in which they selected the most natural grip for either the intact or absent hand without moving.

Spinal muscular atrophy: clinical classification and disease heterogeneity.

The clinical classification of spinal muscular atrophy, caused by deletion of the survival motor neuron 1 gene (SMN1), is based on age at onset and maximum function achieved. Evidence suggests that maximum function achieved is more closely related to life expectancy than age at onset. Therefore, it is important to wait for a period before assigning a patient to 1 of 5 classes of the disorder.
