Metallic contamination of bone during drilling procedures.

J A Hobkirk, K Rusiniak

    Journal of Oral Surgery (American Dental Association : 1965)
    |May 1, 1978
    PubMed
    Summary

    Metallic transfer during bone drilling depends on drill type and usage. New drills transfer more metal than old ones, with less material transferred in subsequent drillings.

    Area of Science:

    • Biomaterials Science
    • Surgical Instrumentation
    • Orthopedic Research

    Background:

    • Understanding metallic debris generation during orthopedic procedures is crucial.
    • Drills and burs are common surgical tools used in bone procedures.
    • The extent and composition of metallic transfer to bone tissue are not fully characterized.

    Purpose of the Study:

    • To investigate the influence of drill shape and material on metallic transfer to bone.
    • To quantify the amount of metallic elements transferred during bone drilling.
    • To assess the impact of drill usage and drilling sequence on metal transfer.

    Main Methods:

    • Utilized radioactive drills and burs for bone drilling experiments.
    • Measured metallic transfer to bone samples using gamma-ray spectrometry.
    • Analyzed variations in metal transfer based on drill characteristics and usage history.

    Main Results:

    • Significant variability in metallic transfer was observed, dependent on drill type, prior use, and specific elements.
    • Iron, cobalt, tungsten, and chromium were the primary elements transferred to bone.
    • New drills transferred more material than used drills; second drilling transferred less than the first.

    Conclusions:

    • Drill material and usage significantly impact metallic transfer to bone.
    • The composition and quantity of transferred metals are element-specific.
    • Minimizing metallic debris in orthopedic surgery may involve considering drill material and replacement protocols.
