<p>This study aimed to evaluate a musculoskeletal screening method for elementary school students using ultrasound and lower limb flexibility assessments, with the goal of early detection of Osgood-Schlatter disease during the growth period. A total of 143 boys in the fourth to sixth grades of elementary school from a single prefecture underwent musculoskeletal screening between November 2021 and February 2023. Using a diagnostic ultrasound device, the tibial tuberosity was observed, and its developmental stage was classified based on Ehrenborg’s four-stage classification (Ehrenborg G and Lagergren C. 1961. <i>Acta Chir Scand</i> 121: 315–327). The presence of Osgood-Schlatter disease was determined based on the presence of irregularities in the ultrasound image. Lower limb flexibility was assessed quantitatively using finger-floor distance (FFD) and heel-hip distance (HHD). The cartilaginous stage (C stage) was the most common developmental stage observed. Osgood-Schlatter disease was identified in eight children (5.6%) and was found only in the epiphyseal (E) and bony (B) stages (<i>p</i> = 0.004, φ = 0.308). HHD was significantly greater in the Osgood-Schlatter group (<i>p</i> = 0.040, r = 0.680). In some children without knee pain or tenderness, irregularities in the tibial tuberosity were detected on ultrasound imaging, suggesting that ultrasound imaging may be useful for the early detection of asymptomatic lesions. This screening approach, which combines ultrasound examination and flexibility assessment, is expected to serve as a novel method for the early detection and prevention of musculoskeletal disorders in children during their growth period. Further large-scale studies and continued investigation into methods for assessing flexibility in growing children are warranted.</p>

<p>Exercise therapy plays a crucial role in functional recovery and improving patients' quality of life in the treatment of low back pain. Orthopedic surgeons diagnose the cause of low back pain through examinations and prescribe appropriate exercise therapy, but collaboration with physical therapists is essential for effective implementation. Orthopedic surgeons identify the cause of low back pain through patient interviews, physical examinations, and imaging studies to determine the most appropriate treatment. In exercise therapy, personalized prescriptions based on an accurate diagnosis are required. However, evidence supporting exercise therapy tailored to specific causes of back pain remains limited, posing a challenge for future research. Meanwhile, the effectiveness of exercise therapy for chronic low back pain is recommended in clinical guidelines, with aerobic exercise and core stabilization training being recognized as beneficial. Physical therapists, based on the diagnosis provided by orthopedic surgeons, conduct detailed evaluations and implement tailored treatments for patients. They utilize a combination of manual therapy, stretching, and core muscle training to alleviate back pain. Additionally, they contribute to the prevention of low back pain through lifestyle guidance and workplace education. Particularly, combining exercise with educational interventions is expected to yield greater preventive effects. However, collaboration between orthopedic surgeons and physical therapists faces challenges such as insufficient information sharing and issues with treatment continuity. To address these problems, utilizing ICT for real-time communication, organizing conferences, and implementing interdisciplinary training programs can be effective strategies. Strengthening cooperation at every stage of diagnosis, treatment, and education is essential for enhancing the effectiveness of low back pain management.</p>

<p><b>Introduction: </b>Brace treatment for adolescent idiopathic scoliosis (AIS) is usually indicated for patients with Risser sign grade 0-3, but not for above grade 4. However, we occasionally see patients whose curves progress even in patients with Risser sign grade 4. We examine Cobb angle progression and risk factors in Risser sign grade 4 cases of AIS.</p><p><b>Methods: </b>From January 2016 to December 2020, 42 AIS patients with Risser sign grade 4 at the first visit to our clinic and were followed up for at least 1 year were included. Patient background, physical findings, and radiological measurements including the Cobb angles were evaluated. Patients were divided into progressive and non-progressive groups to compare their risk factors of scoliosis.</p><p><b>Results: </b>Eight patients were in the progressive group and 34 were in the non-progressive group. In the progressive group, the Cobb angle increased by 7.1 degrees, from 28.7 to 35.8 degrees. The time since menarche was significantly shorter in the progressive group (9.7 months) than in the non-progressive group (24.2 months) (P=0.003). Growth in height was significantly greater in the progressive group (+2.9 cm) than in the non-progressive group (+1.8 cm) (P = 0.02). There were no differences in the other factors.</p><p><b>Conclusions: </b>In this study, curves progressed in approximately 20% of patients with Risser sign grade 4. In cases with short time since menarche or potential for height growth, AIS patients with Risser sign grade 4 may need to take brace therapy.</p>

<p><b>Introduction: </b>In Akita Prefecture, school screening using the Moiré topography have been conducted since 1984, and have been continued after the start of musculoskeletal screening. In this study, we compared the results of the scoliosis examination using the Moiré screening with those of the musculoskeletal screening using data provided by the Akita City Board of Education.</p><p><b>Methods: </b>From 2017 to 2020, 1,442 patients with spinal column findings in musculoskeletal screening and 474 patients with Moiré screening findings underwent secondary examination.</p><p><b>Results: </b>The positive predictive value for the Cobb angle of 10 degrees or more was 39% in the musculoskeletal screening, and 60% in the Moiré screening. The positive predictive value of scoliosis in junior high school students was 57% for the musculoskeletal screening, which was similar to that for the Moiré screening. 13% of the diagnosed cases were newly positive for the musculoskeletal screening and 87% were continuously positive, and most of the cases were diagnosed with scoliosis by the Moiré screening.</p><p><b>Conclusions: </b>The results of this study have once again demonstrated the usefulness of Moiré screening in comparison with musculoskeletal screening. In order to promote the use of Moiré screening, it is necessary to improve the follow-up system after the screening. In addition, it is necessary to approach and cooperate with boards of education and medical associations for the development of medical checkups to resolve issues such as the protection of personal information in order to provide feedback on the results of medical checkups.</p>
