Background: Fusion surgeries for scoliosis patients are believed to deteriorate sports performance; in particular, forward roll should deteriorate, but no literature is available to substantiate this claim.
Hypothesis: The extent of postoperative deterioration can vary according to surgery type or curve type.
Patients And Methods: Idiopathic scoliosis patients between 10 and 29 years of age who underwent correction and fusion surgeries at our hospital were included in this study. Forward roll was recorded on video preoperatively and 1-year postoperatively. Performances were evaluated twice on a 10-point scale by two blinded examiners. Preoperative and 1-year postoperative upright spinal radiographs were analyzed for the Lenke classification, number of fused vertebrae, upper and lower instrumented vertebrae, major curve Cobb angle, thoracic kyphosis, lumbar lordosis, and surgical procedures.
Results: The average age was 16 years. Curve types according to the Lenke classification were: 15, type 1; 5, type 2; 14, type 5; 2, type 6. The mean number of fused vertebrae was 6.9 (3.2 for anterior surgeries and 9.3 for posterior surgeries). The mean preoperative assessment of forward roll was 9.6 points, and the 1-year postoperative assessment was lower at 8.8 points. Cluster analysis classified patients into 3 groups: long fusion with marked performance deterioration (C1), long fusion with minimal deterioration (C2), and short fusion with minimal deterioration (C3). The upper and lower instrumented vertebrae in C1 were more distal than those in C2.
Conclusion: Patients with thoracic curves were classified into two groups, and patients who underwent surgeries with more distal upper and lower instrumented vertebra levels exhibited lower postoperative performance. However, patients with Lenke 5 curves who underwent anterior surgery showed better preoperative performance than other patients who underwent posterior surgery, showing minimal postoperative deterioration.

Article Synopsis
- The study evaluates the challenges and successes of the Improved Community Health Fund (iCHF), a voluntary health insurance scheme in Tanzania, aiming to scale up health interventions in resource-poor settings.
- Using the Expand Net framework, the researchers analyzed the steps taken for scale-up from 2019, including stakeholder engagement, resource mobilization, advocacy, and capacity building.
- Key successes noted were the increasing enrollment and funds, while challenges included advocacy costs, uneven regional equity, a reliance on top-down management, and the impact of local contextual factors.
Article Synopsis
- * Using advanced motion analysis and video technology, the research compared the kinematic characteristics of players' backhand strokes, focusing on joints like the shoulder, elbow, and wrist.
- * Findings revealed that international players had better stroke accuracy and control than national players, with significant differences in trunk flexion and shoulder rotation but no major variances in other kinematic parameters.

Origin of the Efficiency Roll-off in Quantum Dot Light-Emitting Diodes: An Electrically Excited Transient Absorption Spectroscopy Study.

In situ characterizations of charge injection dynamics, equilibrated concentration, and electric field distributions shed light on the critical mechanisms of quantum dot light-emitting diodes (QD-LEDs). In this work, we developed electrically excited transient absorption spectroscopy, which can provide the above key information, to investigate the efficiency roll-off of QD-LEDs. We found that the average electron populations per QD are low when QD-LEDs exhibit efficiency roll-off, excluding Auger recombination as the main cause.
