Regional Muscle Balance and Hip Fracture Patterns

Hip fractures are common in older adults and are often associated with muscle loss and frailty. While many studies focus on overall muscle reduction (sarcopenia), the role of regional muscle balance around the hip remains unclear. This prospective observational study aims to evaluate whether differences in muscle distribution, particularly between the gluteus medius and psoas muscles measured using computed tomography (CT), are associated with different hip fracture patterns. The study also investigates the potential effects of socioeconomic status, nutritional risk, and comorbidity burden on fracture configuration. Understanding how regional muscle characteristics relate to hip fracture types may provide new insight into biomechanical mechanisms and support future prevention and rehabilitation strategies for older adults.
