[Multiple fragility fractures following hip fracture: Lessons from a multidisciplinary rehabilitation approach].

A 58-year-old woman presented with multiple fragility fractures nine months after a a pertrochanteric hip fracture in the context of severe osteoporosis. Despite initial treatment with alendronate, calcium and cholecalciferol, she presented new pelvic and vertebral fractures, associated with persistently low vitamin D levels related to irregular treatment adherence. From premorbid functional independence, she developed severe disability, with loss of autonomous ambulation and dependence for basic activities of daily living. A multidisciplinary approach, focused on optimization of pharmacological treatment together with a structured rehabilitation programme, facilitated progressive functional recovery. This case highlights three key lessons: the role of hip fracture as a sentinel event, the importance of correcting vitamin D deficiency, and the value of coordinated multidisciplinary care in the comprehensive management of patients with severe osteoporosis.
