Abstract
OBJECTIVES
To explore the injury mechanism of ankle fracture inferred by the Lauge-Hansen classification with the application of medical imageology and its application value in forensic medicine.
METHODS
A total of 32 ankle fracture cases with known injury mechanism were collected from January 2013 to May 2018, which were identified in Yongkang Public Security Bureau, Zhejiang Province. The Lauge-Hansen classification of ankle fracture was performed by three forensic experts based on the data of X-ray and CT image. Fisher's exact test and Kappa consistency analysis were performed by SPSS 20.0 statistical software to compare the results of the Lauge-Hansen classification with the injury mechanism of ankle fracture obtained through the criminal evidence.
RESULTS
In 32 cases, 84.4% (27/32) ankle fractures were classified according to the Lauge-Hansen classification based on medical imaging. The mechanism of ankle fracture identified by the Lauge-Hansen classification was consistent with that obtained through the criminal evidence.
CONCLUSIONS
Based on medical imaging, the Lauge-Hansen classification can be well applied to infer the injury mechanism of ankle fracture in part cases, and provide objective evidence for the crime scene reconstruction of criminal cases.
