Aims: Closed suction subfascial drainage is widely used after instrumented posterior spinal fusion in patients with a spinal deformity. The aim of this study was to determine the effect of this wound drainage on the outcomes in patients with adolescent idiopathic scoliosis (AIS). This was a further analysis of a randomized, multicentre clinical trial reporting on patients after posterior spinal fusion using segmental pedicle screw instrumentation.

Objective: This study evaluates the 10-year pulmonary function outcomes for patients with structural thoracic adolescent idiopathic scoliosis (Lenke curve types 1-4, 6) after segmental pedicle screw instrumentation.
Summary Of Background Data: Adolescent idiopathic scoliosis with thoracic curves is associated with reduced pulmonary function preoperatively.
Article Synopsis
- - Copepod size and energy content are affected by temperature and food availability, which is important for planktivorous consumers like the endangered North Atlantic right whale.
- - Analysis of historical data (1990-2020) showed that copepod size and lipid content vary across five regions of the Northwest Atlantic, with larger, more energy-rich copepods found in the Gulf of St. Lawrence and St. Lawrence Estuary compared to the Gulf of Maine and Scotian Shelf.
- - These regional differences in copepod size and energy can influence the foraging success and habitat suitability for North Atlantic right whales, highlighting the importance of understanding prey energy content for their conservation.
Purpose: Spinal osteotomies are often essential in the treatment of congenital scoliosis. Risk factors for bleeding in these patients needing extracavitatory approaches, especially hidden blood loss, are sparsely investigated. We aimed to investigate the bleeding characteristics and hidden blood loss in paediatric patients undergoing spinal osteotomies for congenital scoliosis.

Study Design: Prospective cohort study.
Summary Of Background Data: Lenke classification is used to define the curve type in adolescent idiopathic scoliosis (AIS). The association of Lenke classification and long-term postoperative health-related quality of life (HRQoL) remains unclear.
