Objective:
To evaluate the mechanisms, consequences, and management strategies of post-stroke bone fragility and propose approaches for improved prevention of fracture-related morbidity in stroke survivors.
Background:
Stroke survivors experience significant bone mineral density (BMD) loss, particularly in hemiplegic limbs, due to reduced mobility, muscle weakness, and altered bone remodeling. This skeletal fragility increases fracture risk, compounding neurologic impairment and diminishing functional independence. Despite recognition of these complications, osteoporosis screening and treatment remain inconsistent in post-stroke care.
Design/Methods:
This review synthesizes current evidence on the timing and extent of post-stroke bone loss, associated risk factors, and clinical outcomes. Literature on rehabilitation strategies, pharmacologic interventions, and screening practices was analyzed to identify key gaps and opportunities for improvement.
Results:
Early and significant BMD decline is well-documented, with hemiparetic limbs showing rapid demineralization. Fracture risk is elevated compared to age-matched controls, with hip fractures contributing to greater long-term disability and reliance on institutional care. Rehabilitation approaches, including structured physical activity and early mobilization, show potential to attenuate bone loss, while pharmacologic strategies such as bisphosphonates and vitamin D supplementation remain underutilized. Current protocols rarely include routine osteoporosis screening or fracture-prevention interventions in stroke pathways.
Conclusions:
Post-stroke bone fragility represents a predictable and preventable complication that is under-recognized in clinical practice. Timely diagnosis, incorporation of bone health screening, and individualized rehabilitation can reduce fracture burden. Multidisciplinary collaboration among neurology, rehabilitation, geriatrics, and orthopedics is essential to address this gap. Reframing bone fragility as a core outcome of stroke recovery, rather than a secondary issue, may improve long-term function and quality of life for survivors.
