Comparative analysis of body parameters for fracture and post-healing patient using a non-invasive bioimpedance device

Bone fracture assessment and follow-up commonly rely on imaging techniques such as X-ray and CT, which, although effective, involve radiation exposure and limited feasibility for frequent monitoring. This study presents a comparative analysis of body impedance parameters in fractured and non-fractured individuals to explore the potential of bio-impedance as a non-invasive diagnostic and monitoring tool. Data were collected from 65 patients during the fracture phase and after complete healing, allowing direct comparison of electrical characteristics associated with tissue recovery. The study focused on key parameters such as impedance magnitude, and phase angle to assess their variation with bone healing. A portable bio-impedance measurement device was developed to acquire real-time data with high accuracy and reproducibility. The results indicate consistent within-subject trends, with higher impedance and phase angle values observed in the post-healing condition. These findings suggest that segmental BIA measurements may reflect changes associated with fracture recovery; however, no causal physiological mechanisms are inferred. The developed system proved effective in capturing these physiological transitions without the need for invasive or radiological procedures. This work establishes bio-impedance analysis as a promising, safe, and cost-effective approach for monitoring bone healing and assessing fracture status. The proposed device can serve as a valuable clinical tool for orthopedic applications, enabling early detection of healing progress and personalized rehabilitation strategies.
