Article Abstract
Background: Although instrumented fusion is the most widely accepted surgical treatment for adolescent idiopathic scoliosis, it leads to permanent spinal motion loss and an increased risk of adjacent segment degeneration. Consequently, there is great interest in finding nonfusion methods to correct scoliosis in patients with adolescent idiopathic scoliosis. The aim of this manuscript is to report a case of adolescent idiopathic scoliosis (Lenke 5C) treated by dynamic stabilization without fusion using the Dynesys system.
Case Presentation: The patient was a 17-year-old East Asian female. Before the operation, the major lumbar curve was 32.2° and the lumbosacral curve was 18.5°, with the Risser sign at grade 4. The procedure was performed using the Wiltse approach. The extent of fixation was from the cephalic horizontal vertebra to sacrum. The scoliosis was corrected by the unequal length of the spacers on the concave/convex side. We obtained a good correction of scoliosis, which was maintained during the 5-year follow-up. We also observed less intraoperative blood loss, faster postoperative recovery, and more motion preservation.
Conclusion: In this case, dynamic stabilization was demonstrated to be technically feasible for the treatment of thoracolumbar/lumbar moderate scoliosis. The benefits are related to less damage to the soft tissues, reduced blood loss, and motion preservation. However, further studies are needed to determine the effectiveness of the described surgical strategy.

Atypical proximal tibial fractures in adolescents are rare, particularly when linked to hormonal therapy for short stature. This case series reports the clinical and imaging features of atypical proximal tibial and distal femoral physeal fractures in male adolescents undergoing combined growth hormone (GH) and aromatase inhibitor (AI) therapy for idiopathic short stature. We report three cases of skeletally immature male adolescents (ages 12-16) treated with GH and anastrozole who presented with acute leg pain following low-energy trauma during soccer.

Introduction: Human papillomavirus (HPV) infection has been implicated in autoimmune processes, yet concerns remain about the potential autoimmune risks of HPV vaccination. Juvenile idiopathic arthritis (JIA) is a chronic autoimmune condition that typically manifests in childhood. The relationship between HPV vaccination and the development of JIA remains uncertain.

Background: Vertebral body tethering (VBT) offers an alternative treatment for patients with idiopathic scoliosis. We present our finalized Food and Drug Administration Investigational Device Exemption (IDE) study results on VBT.
Methods: We retrospectively reviewed patients with Lenke Type IA/B curves who underwent VBT between 2011 and 2015.

Background: Neutropenia is a common laboratory finding in children, therefore it is a common referral reason to pediatric hematology units. This study hypothesizes that most neutropenic children do not require pediatric hematology consultation, and that key clinical indicators can guide the need for referral.
Methods: Medical records of 180 patients who were admitted to a tertiary reference center, were evaluated in terms of demographical data, physical examination findings, laboratory findings, and outcome measures.
Is fusion to the stable sagittal vertebra necessary to avoid distal junctional kyphosis in thoracic adolescent idiopathic scoliosis?

Spine Unit, Department of Orthopedic Surgery, Rigshospitalet, Inge Lehmanns Vej 6, 2100, Copenhagen, Denmark.
Study Design: This is a retrospective single-center study.
Purpose: The purpose is to investigate the incidence of distal junctional kyphosis (DJK) when fused proximal to the stable sagittal vertebra (SSV) in adolescent idiopathic scoliosis (AIS) patients undergoing selective thoracic fusion.
Methods: We retrospectively reviewed a consecutive cohort of surgically treated AIS patients with Lenke 1-2 A/B curves between 2011 and 2022 with a minimum of 2 years of follow-up.
