Abstract
Polymer orthopedic implants offer radiolucency and mechanical compatibility with bone, but long-term success depends on maintaining a stable implant–tissue interface. Routine imaging is widely available for follow-up, yet interface integrity is commonly judged qualitatively, limiting early detection of fixation compromise and reducing comparability across devices and time points. This work presents an image-based methodology to quantify interface integrity by extracting interpretable interface descriptors from a standardized interface belt around the implant boundary. The approach combines boundary-geometry roughness metrics with texture-transition analysis based on local entropy and complementary texture statistics to generate an adhesion integrity score and longitudinal change indicators. Example results demonstrate stable indicator trajectories in a stable-fixation cohort and progressive degradation patterns in a compromised cohort, with strong cross-sectional separability at 12 months using both roughness and entropy-transition features. End-to-end performance indicates that accurate boundary localization supports robust feature computation and enables practical throughput for follow-up imaging analysis. The proposed framework provides a reproducible, non-invasive pathway for monitoring interface condition and supporting integrity assessment of polymer orthopedic devices using imaging-derived indicators.
Keywords: Polymer orthopedic implants; Implant–tissue interface; Texture analysis; Local entropy; Adhesion integrity scoring.
