Brief summary
The study aims to construct an early warning model for Osteoporotic Vertebral Compression Fracture (OVCF) by integrating TCM syndrome patterns with modern risk factors. This is a multi-center cohort study on OVCF integrated with disease and syndrome differentiation in Traditional Chinese Medicine (TCM).
Detailed description
The subjects are selected according to the inclusion criteria and exclusion criteria. A total of 200 subjects will be recruited from four participating tertiary hospitals and categorized into four groups: individuals with normal bone mass, osteopenia, osteoporosis, and Osteoporotic Vertebral Compression Fracture (OVCF) . Data collection encompasses three levels: * Macro-level: Demographics, lifestyle, medical history, and physical metrics. * Meso-level: TCM syndrome diagnoses, bone mineral density (BMD), MRI assessments, and functional scores (VAS, ODI). * Micro-level: Serum biomarkers related to bone metabolism, lipids, inflammation, and muscle health. Strict quality control measures will be implemented, including researcher training and data monitoring. The integrated database and analytical framework are designed to develop a practical, population-specific risk prediction tool for OVCF.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bone Mineral Density (BMD) | Baseline | DXA will be used to measure lumbar spine (L1-L4) and bilateral hip density, recording the T-score for each site. Instrument precision will be set to 1% (i.e., repeated measurement error \< 1%). Professionals will be responsible for post-use accuracy checks and maintenance. |
Secondary

|---|---|---|
| Muscle Strength | Baseline | Left and right handgrip strength in kilograms, which is determined by a handheld dynamometer. The normal range varies by age, gender, and dominant hand. When it is lower than the normal range, it may indicate muscle weakness, sarcopenia, or neuromuscular disorders; when it is higher than the normal range, it typically reflects good musculoskeletal health and physical fitness. |
| The bone marrow fat fraction (FF) | Baseline | The bone marrow fat fraction (FF) of lumbar vertebrae (expressed as a percentage), which is determined by magnetic resonance imaging (MRI) analysis. The normal range varies with age and vertebral level, typically between 30-50% in healthy adults. When it is higher than the normal range, it may indicate osteoporosis, aging, or metabolic bone disease; when it is lower than the normal range, it may suggest conditions such as bone marrow edema, inflammation, or hematopoietic disorders. |
| Paravertebral muscle area | Baseline | The paravertebral muscle area (in cm²), which is determined by magnetic resonance imaging (MRI) analysis. The normal range varies based on vertebral level, age, and gender. When it is smaller than the normal range, it may indicate muscle atrophy, sarcopenia, or degenerative changes. |
| Fatty infiltration | Baseline | The degree of paravertebral muscle fatty infiltration (expressed as a percentage or fat fraction), which is determined by magnetic resonance imaging (MRI) analysis.

| Vertebral bone quality (VBQ) score | Baseline | The vertebral bone quality (VBQ) score, which is determined by magnetic resonance imaging (MRI) analysis. The normal range is 1.5-3.0. When it is higher than the normal range, it indicates poor bone quality and an increased risk of osteoporotic vertebral fractures; when it is lower than the normal range, it indicates better bone quality and a lower fracture risk. |
| Visual Analogue Scale (VAS) Score | Baseline | Draw a straight line with a length of 10 cm on the white paper and mark painless and severe pain on both ends respectively to form VAS.

Painless is represented by 0; 1-3 points represent mild pain; 4-6 points represent moderate pain, which is strong but tolerable; 7-10 points represent severe pain, gradually reaching intolerable level, which is severe pain. Draw a 10 cm long on a piece of white paper. |
