This review addresses this gap by delineating the multidimensional risk network for RA-OP and evaluating the development, performance, and applicability of current CPMs. We find that despite evolution from basic to sophisticated biomarker-integrated algorithms, most CPMs are constrained by modest sample sizes, insufficient external validation, and suboptimal clinical translatability. The current paradigm focuses predominantly on diagnosis rather than prognosis. To address these limitations, future research should aim to enhance the methodological rigor and generalizability of models, expand their predictive scope to encompass future risk of OP and fractures, and develop RA-specific fracture prediction tools that incorporate disease-specific pathophysiology, with performance rigorously benchmarked against established tools such as the fracture risk assessment tool (FRAX).

A literature search up to April 2024 was conducted in PubMed, Scopus, Web of Science, and the Cochrane Library. Clinical trials involving adults with OVFs were included, focusing on physical capacity (primary outcome) and other health outcomes. Study selection, bias assessment, and data extraction were independently conducted by two authors, with a third author resolving conflicts. Nineteen studies were included in the meta-analysis of exercise interventions. Exercise interventions were analyzed using a standardized mean difference (SMD) meta-analysis, with additional sensitivity analyses. Physical exercise significantly improves functional capacity (SMD -0.41; 95% CI -0.69 to -0.14; p 0.003), aerobic capacity, balance, trunk muscle strength, pain, and quality of life in patients with OVF. No significant effects were observed on thoracic posture or fear of falling. Adverse event risk was low (6%), comparable to usual care or daily activities. Health education interventions (two studies) were synthetized narratively, both showing improvements in pain, mobility, and patient knowledge. Physical exercise is effective and safe in the recovery of OVFs; thus, its prescription is recommended.
