Objectives

Narrative objectives1

This study aims to investigate the association between the cross-sectional areaof trunk muscles measured using preoperative CT images and walking ability one month after surgery,as well as to identify independence.The findings are expected to contribute to improving the accuracy of prognosis prediction based on preoperative imaging and developing individualized early rehabilitation programs.

Other related information

This is a single-center prospective observational cohort study involving patients aged 65 years or older who are admitted to Maki Hospital with proximal femoral fractures. Cross-sectional areas of the erector spinae, transversus abdominis, rectus abdominis, internal oblique, and external oblique muscles will be measured using preoperative CT images obtained as part of routine clinical care. Clinical information, including age, sex, cognitive function, nutritional status, sarcopenia status, and fracture- and surgery-related factors, will be collected from medical records. Walking ability one month after surgery will be assessed using the walking item of the Functional Independence Measure (FIM). For sensitivity analysis, walking ability will also be classified into four groups: unable to walk (wheelchair users), walker users, T-cane users, and independent walkers. The study will investigate the association between preoperative trunk muscle cross-sectional areas and walking ability one month after surgery, as well as factors associated with postoperative walking ability. Participants will be selected according to the eligibility and exclusion criteria specified in the study protocol, and written informed consent will be obtained from the participants or their legally authorized representatives.
