Abstract: Objective: To develop a prevention and management program for osteosarcopenia in elderly patients with hip fracture and to evaluate its effectiveness, so as to provide a reference for clinical practice. Methods: Guided by a fracture liaison service model as framework, the program was developed through a literature review and expert consultation. Elderly hip fracture patients hospitalized in the orthopedic department of a tertiary grade A hospital in Jiangsu province were recruited. Forty-four patients hospitalized from September 2024 to February 2025 were assigned to the control group and received standard care, while forty-two patients hospitalized from March to August 2025 were assigned to the intervention group and received the developed program. Grip strength, bone metabolism markers, hip function, and osteoporosis self-management behavior of patients at three months postoperatively were compared between the two groups. Results: At 3 months postoperatively, there was no statistically significant difference in the incidence of osteosarcopenia between the intervention group (35.7%) and the control group (54.5%) (P>0.05). However, the intervention group exhibited significantly higher grip strength [(19.82±1.33) kg vs (19.19±1.31) kg], greater improvements in bone metabolism markers, and higher scores in hip function and osteoporosis self-management compared with the control group, all with statistically significant differences (all P<0.05). Conclusion: The developed program is scientifically sound and feasible, which can effectively improve elderly hip fracture patients’ grip strength, promote positive bone metabolism, and enhance their hip function and self-management behaviors.
