Bone remodeling is a natural process that is potentially problematic for radiographic comparisons because it can occur after antemortem (AM) imaging, thus interfering with the comparability of AM and postmortem (PM) radiographs from the same individual. While the effects of age-related remodeling have been studied, limited attention has been given to trauma-related remodeling with respect to radiographic comparisons. This report adds to the latter topic by presenting a case of AM clavicle fracture that developed into a pseudo-arthrosis over a 12-month period prior to the individual's death. Even though remodeling was discernable along the fracture margins, adjacent skeletal features on the PM radiograph remained unaltered and constituted compelling evidence for the identification. This case illustrates the potential of using both normal and pathological anatomy concurrently to maximize the surety of findings from radiographic comparisons.
骨重塑是一个自然过程，对于影像学比较而言可能存在问题，因为它可在生前（AM）成像后发生，从而干扰来自同一个体的生前和死后（PM）X线片的可比性。虽然已经研究了与年龄相关的重塑的影响，但关于影像学比较，与创伤相关的重塑受到的关注有限。本报告通过呈现一例生前锁骨骨折在个体死亡前12个月发展为假关节的病例，补充了后一个主题。尽管在骨折边缘可察觉到重塑，但死后X线片上相邻的骨骼特征未发生改变，构成了鉴定的确凿证据。该病例说明了同时使用正常和病理解剖结构以最大限度提高影像学比较结果确定性的潜力。
