Setting And Participants: This study was conducted using data from the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study.
Article Synopsis
- This study investigates how lumbar spine disorders, specifically scoliosis, affect the occurrence of asymmetric hallux valgus (HV) among participants in a nationwide study in Japan.
- The researchers categorized HV severity using radiographic angles and identified asymmetric HV as a difference of two or more severity grades between the left and right foot.
- Results showed that, out of 1997 participants, those with asymmetric HV had a higher incidence of lumbar issues, with scoliosis being a significant independent factor that increased the likelihood of asymmetric HV.
Article Synopsis
- The study aimed to identify factors linked to locomotive syndrome (LS) using medical questionnaires and machine learning techniques.
- A total of 1,575 participants underwent LS risk tests, and after data cleaning, 331 questionnaire items were analyzed to determine their association with LS through advanced statistical methods.
- Nine key factors, especially age and back pain during walking, were identified as strongly correlated with LS, showing better predictive performance compared to existing assessment tools.
Research on complications necessitating reoperation following vertebroplasty related to hydroxyapatite (HA) blocks is limited. We present the case of a 25-year-old woman who underwent posterior fixation and vertebroplasty using HA blocks for a T12 burst fracture. Postoperative computed tomography revealed anterior protrusion of some blocks, with consequent compression of the descending aorta.

- The study aimed to analyze the changes over ten years in the medial minimum joint space width (mJSW) and osteophyte area (OPA) of knee joints among Japanese adults using data from two independent cohorts.
- Data was collected from nearly 3,000 participants in initial surveys between 2005-2007, followed by another survey with about 2,400 participants from 2015-2016, focusing on measuring mJSW and OPA using automated systems.
- Results showed a significant increase in mJSW for both men and women over the ten years, suggesting a potential decrease in knee osteoarthritis incidence and progression, while OPA trends were less consistent.
Background: Muscle weakness is associated with adverse clinical outcomes including disability and mortality. We report demographic, anthropometric and lifestyle correlates of grip strength in UK and Japanese population-based cohorts.
Aim: To report prevalence of low grip strength according to 2019 European Working Group on Sarcopenia in Older People (EWGSOP2) and 2019 Asian Working Group for Sarcopenia (AWGS 2019) thresholds and to consider correlates of grip strength in Eastern and Western populations.
Background: In surgery for cervical spondylotic myelopathy (CSM) with spondylolisthesis, there is no consensus on the correction and fixation for spondylolisthesis. The authors retrospectively studied whether the correction of single-level fixation with lateral mass screws (LMSs) could be maintained.
Observations: The records of patients with CSM with spondylolisthesis who had been treated with posterior decompression and single-level fusion with LMSs from 2017 to 2021 were retrospectively reviewed.
Article Synopsis
- The study examined the potential causal relationship between the medial partite hallux sesamoid (MPHS) and hallux valgus (HV) using data from a diverse group of participants aged 21-95 years.
- Out of 3,994 feet analyzed, 12.7% had MPHS, with notable differences in prevalence between men and women, and a significant decrease in MPHS occurrence with age.
- The findings suggest that while MPHS is associated with an increased HV angle, the relationship is stronger in younger populations, indicating that MPHS may contribute to the development of HV rather than being caused by it, particularly in younger adults.
Article Synopsis
- A study in Japan investigated the prevalence of atrophic gastritis (AG) and infection from 2005 to 2016 using data from 3,596 participants, showing a significant decline in both conditions over the decade.
- At baseline, AG prevalence was 40.1% and infection was 52.2%, while 10 years later, AG rates dropped to 25.8% and infection rates to 35.5%.
- The research indicated that AG prevalence increased with age, while infection prevalence showed an inverted U-shaped trend, suggesting that the changes may impact related health issues like colorectal neoplasia and arteriosclerosis.
Study Design: A single-center prospective observational study.
Objective: The aim was to clarify the usefulness of assessing advanced glycation end products (AGEs) by noninvasive skin autofluorescence in patients with ossification of the posterior longitudinal ligament (OPLL).
Summary Of Background Data: AGE accumulation is associated with various systemic disorders, including aging, diabetes mellitus, and obesity.
Article Synopsis
- - The study examined hip osteoarthritis (OA) trends in Japanese men and women over a decade using data from a major disability research study, comparing baseline data from 2005-2007 with follow-up data from 2015-2016.
- - Analyzed participants included 2924 individuals at baseline and 2347 in the follow-up, focusing on those aged 40-89, and results showed varied prevalence of hip OA, particularly comparing younger adults to older ones.
- - Findings indicated a general decrease in the prevalence of radiographic hip OA over the 10-year period, suggesting an overall improvement in hip health in the population studied.
Introduction: This study aimed to clarify the trends in the prevalence of osteoporosis among general inhabitants using population-based cohort data of the baseline and the survey 10 years later.
Materials And Methods: The baseline survey of the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study was conducted in 2005-2007; 1690 participants (596 men, 1094 women, mean age 65.2 years) completed all examinations of osteoporosis, including a questionnaire of medical information in the present/past and bone mineral density measurement using dual-energy absorptiometry.
Introduction: Locomotive syndrome (LOCOMO) is defined by the Japanese Orthopaedic Association (JOA) as a condition requiring nursing care due to a decline in mobility resulting from musculoskeletal disorders. In 2020, the JOA announced the new definition of LOCOMO stage 3 and revision of clinical decision limits in stages of LOCOMO. However, there are few reports on the epidemiological indices of LOCOMO.

Age-related changes in spinopelvic sagittal alignment have been recently reported; thus, sagittal realignment should consider age-related changes. This study aimed to investigate the relationship between age-specific sagittal spinopelvic radiographic parameters and low back pain (LBP) to support the establishment of age-specific realignment targets for patients with ASD.
View Article and Find Full Text PDFBackground: There has been a paucity of literature revealing the discrepancy between self-recognition about hallux valgus (HV) and radiographically-evaluated foot configuration. Knowing this discrepancy will help to make a comparative review of the findings of previous literatures about epidemiological studies about the prevalence of HV.
Questions/purposes: (1) Is there a discrepancy between radiographically-assessed and self-recognized HV in the general population? (2) What factors affect the self-recognition of HV in the general population?
Methods: The fifth survey of the Research on Osteoarthritis/Osteoporosis against Disability study involved 1996 participants who had undergone anterior-posterior radiography of bilateral feet and answered a simple dichotomous questionnaire on self-recognition of HV.
: The influence of changes in spinal alignment after total hip arthroplasty (THA) on improvement in lower back pain (LBP) remains controversial. To evaluate how changes in spinal malalignment correlate with improvement in preoperative LBP in patients who underwent THA for hip osteoarthritis. : From November 2015 to January 2017, 104 consecutive patients who underwent unilateral THA were prospectively registered.
