Abstract
Objectives: The current study sought to investigate whether physical function and activity were associated with hip structural analysis (HSA) parameters on the non-fracture side of patients with hip fractures.
Methods: Participants were patients with unilateral hip fracture treated by surgery. HSA of the proximal femur was conducted based on dual-energy x-ray absorptiometry data. HSA parameters in the narrow neck region included cross-sectional area (CSA), cross-sectional moment of inertia (CSMI), section modulus (SM), and buckling ratio (BR). Hierarchical multiple regression analysis was conducted to identify predictors of HSA.
Results: Except for the adjustment variables, age, gender and BMI, other variables were extracted. Hierarchical multiple regression analysis (standardised partial regression coefficients) identified movement control during one-leg standing on the non-fractured side (0.15) as factors associated with CSA. Hierarchical multiple regression analysis (standardised partial regression coefficients) identified hand grip (0.12, 0.23) as factors associated with CSMI and SM, respectively. Hierarchical multiple regression analysis (standardised partial regression coefficients) identified presence of steroid (0.23) and cerebrovascular disease (0.19) as factors associated with BR. The coefficients of determination adjusted for degrees of freedom (R2) were 0.545, 0.331, 0.401, and 0.148 for CSA, CSMI, SM, and BR, respectively.
Conclusions: Our results indicate that movement control during 1-leg standing and muscle strength may be important for maintaining and improving bone strength.
期刊介绍:
HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice.
The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit.
HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are:
• Biomaterials
• Biomechanics
• Conservative Hip Surgery
• Paediatrics
• Primary and Revision Hip Arthroplasty
• Traumatology
