[Morphologic aspects of angle grinder injury].

W Thurner, S Pollak

    Beitrage Zur Gerichtlichen Medizin
    |January 1, 1989
    PubMed
    Summary

    Angle grinder injuries create unique wound characteristics on soft tissue and bone. Analyzing these features, including skin notches and bone fractures, aids in tool identification and scene interpretation.

    Area of Science:

    • Forensic pathology
    • Biomechanics

    Context:

    • Analysis of injuries from power tools
    • Examination of tool marks on biological tissues

    Purpose:

    • Characterize angle grinder injuries
    • Identify tool-specific wound features
    • Assess trace evidence for forensic analysis

    Summary:

    • Experiments on soft-tissue and bone revealed distinct morphological features of angle grinder injuries.
    • The grinding wheel produces severances with localized tissue loss, leaving characteristic tool marks.
    • Superficial skin notches and incomplete bone severances are significant indicators.
    • Trace evidence transfer between the tool and the biological sample is crucial for identification.

    Impact:

    • Enhances the ability to identify tools used in causing injuries.
    • Improves the interpretation of crime scenes involving angle grinder use.
    • Provides valuable data for forensic investigations and expert testimony.
