Objective:
In diffuse idiopathic skeletal hyperostosis (DISH), spinal ankylosis may occur due to longitudinal ligament ossification. DISH can lead to back pain, impaired mobility, and displaced fractures after minor trauma. Its etiology is unknown, but is associated with obesity and type 2 diabetes mellitus. We investigated the prevalence of DISH in an outpatient population in the Netherlands.
Methods:
Chest radiographs of 501 patients (age > 50 yrs) referred to our institution by general practitioners for non-spine-related conditions were reviewed. DISH was established according to defined criteria; 3-level involvement was defined as pre-stage DISH. Logistic regression analysis was used to investigate the influence of age and sex on the prevalence of DISH.
Results:
The overall prevalence of DISH was 17.0% (95% CI 13.7-20.3). A significant increase with age was observed (odds ratio 1.03, 95% CI 1.01-1.05; p = 0.006). The odds ratio of male sex was 1.85 (95% CI 1.20-2.86; p = 0.006). The individual predicted probability of developing DISH was 32.1% in 80-year-old men and 16.9% in women of the same age. Pre-stage DISH was found in 4.6% of the individuals and was more frequent in women.
Conclusion:
The prevalence of DISH in this outpatient cohort was 17.0%, which is high compared to recent reports. Age and sex were significantly related to the presence of DISH, suggesting that men and older individuals have a higher probability of developing DISH.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
