2D and 3D Classification Systems for Adolescent Idiopathic Scoliosis: Clinical Implications and Technological Advances

Classification systems for Adolescent Idiopathic Scoliosis (AIS) play an important role in guiding both surgical planning and conservative treatments. Traditional 2D classification systems, such as the Lenke, King and Lehnert-Schroth classifications, have been widely used for the clinical diagnosis and treatment of scoliosis. However, with the growing understanding of the three-dimensional nature of scoliosis and advancements in 3D reconstruction technologies, 3D classification systems are gaining increasing attention. This paper reviews the current applications, advantages, and limitations of different 2D and 3D classification systems, focusing on their clinical significance in treatment planning. While 3D classification systems offer clear advantages in capturing the complexity of spinal deformities, their clinical implementation faces challenges such as high costs and technical complexity. Additionally, studies show that computer-assisted technologies, artificial intelligence can significantly improve the accuracy and consistency of classification systems, reducing human errors. The paper also explores the future directions of classification system development, emphasizing the potential of combining 2D and 3D technologies and the impact of these advancements on personalized scoliosis treatment.

Effect of therapeutic exercises on the progression of adolescent idiopathic scoliosis: a protocol of a systematic review

INTRODUCTION

Adolescent idiopathic scoliosis (AIS) affects an estimated 200 million adolescents globally and curvatures exceeding 30° at skeletal maturity are associated with increased health risks in adulthood. The International Society for the Orthopedic and Rehabilitative Treatment of Scoliosis recommends specific therapeutic exercises to prevent the progression of AIS. However, studies have questioned the effects of specific and general therapeutic exercises on the progression of AIS. This systematic review will evaluate the effectiveness of general and specific therapeutic exercises in preventing Cobb angle progression compared with other conservative interventions.

METHODS AND ANALYSIS

We will search MEDLINE (via PubMed), EMBASE, CENTRAL, PEDro and CINAHL from inception to 14 December 2023. Randomised clinical trials involving individuals aged 10 to 18 years with a Cobb angle above 10° will be considered. The effectiveness of therapeutic exercises will be compared with minimal intervention, other exercises and brace use, alone or in combination with exercise. The primary outcome is the Cobb angle measurement, with subgroup analyses assessing severity based on SOSORT classifications. The risk of bias will be assessed using the PEDro scale and Grading of Recommendations, Assessment, Development and Evaluation will be used to assess certainty of evidence. The Review Manager 5.4 software will be used for meta-analysis. The protocol follows the Cochrane Handbook for Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines.

ETHICS AND DISSEMINATION

This is a literature-based study and ethical approval is not required. The findings will be disseminated through peer-reviewed publications. PROSPERO registration number CRD42020156639.

The effect of stretching exercises before orthotic treatment on the immediate in-orthosis correction of the patients with adolescent idiopathic scoliosis: A pilot study

BACKGROUND

Stretching exercise is generally used for improving flexibility. However, its application to promote orthotic treatment for patients with adolescent idiopathic scoliosis (AIS) remains unknown.

OBJECTIVE

This study was to explore the effect of pre-orthosis stretching exercises on spinal flexibility and initial in-orthosis correction for the patients with AIS.

STUDY DESIGN

A pilot-controlled study.

METHODS

An experimental group (EG) of 13 subjects (10 girls and 3 boys) with AIS allocating to self-stretching exercises and a control group (CG) of 19 AIS subjects (14 girls and 5 boys) with no stretching before orthosis fitting were recruited. The spinal flexibility of the EG was evaluated with an ultrasound imaging system and physical measurements. The initial in-orthosis correction rates between the 2 groups were compared with the independent t test, and the correlation analysis between the spinal flexibility measured from ultrasound images and physical measurement was performed with the Pearson correlation test.

RESULTS

The initial Cobb angle of EG and CG were 25.70° ± 7.30° and 28.09° ± 5.58°, respectively. No significant difference was observed between the initial in-orthosis Cobb angle of EG (11.13° ± 6.80°) and CG (15.65° ± 9.10°) (p = 0.06). However, the spinal flexibility after stretching exercises was improved (p < 0.001), and the spinal flexibility changes measured with ultrasound and physical forward-bending method were significantly correlated (r = 0.57, p < 0.05).

CONCLUSION

Stretching exercises before orthotic treatment could improve the spinal flexibility but did not cause a better in-orthosis correction. A study with a larger sample size and longer follow-up period should be conducted to investigate the long-term effect of stretching exercises.

The New Modular Sforzesco Brace (Modular Italian Brace) Is as Effective as the Classical One: A Retrospective Controlled Study from a Prospective Cohort

Background: The Sforzesco brace is a very rigid push-up brace effective in adolescent idiopathic scoliosis (AIS). We recently developed a new Sforzesco brace based on modularity (the Modular Italian brace-MI brace) that could allow standardization, facilitating global expertise diffusion, increased modifiability and adaptability, and cost savings due to longer brace life. We aimed to compare the short-term results of the two braces. Methods: The retrospective study included 231 consecutive AIS treated with a MI brace (N = 53) or Sforzesco brace (N = 178). The main outcome was the first 6-month follow-up out-of-brace radiograph Cobb angle change. Secondary outcomes included the in-brace Cobb degrees and aesthetics (TRACE), prominence (angle of trunk rotation and mm), kyphosis, and lordosis changes. Results: The two groups were similar at baseline, apart from more immature patients in MI brace. Both braces reduced the Cobb angle (-6° out-of-brace; -16° in-brace) without differences between groups. All secondary outcomes improved, apart from a statistically and clinically insignificant 3° kyphosis reduction. The MI brace participants were 4.9 times more likely to improve the Cobb angle than the Sforzesco brace (OR = 4.92; 95%CI 1.91-12.64; p = 0.001). Conclusions: These findings suggest that the MI-brace can be safely used instead of the classical Sforzesco brace. However, further studies of different designs and longer follow-ups are needed to confirm these findings.
