Broken screw

    I had a patient last week with a broken Charlotte screw. The middle of the Charlotte (like a Herbert screw) is non threaded and I had a bear of a time getting it out.

    Does anyone know of a screw extractor that works for these non threaded screws?

    Steve,

    I saw a picture of the screw. Could you use a needle nose pliers, or a mosquito hemostat to grab it? If it sticks out, surgical vice grips work well.

    Regards,

    Hi Stanley:
    It was a failed first met-cun fusion. The screws were 3.5 and I just couldn't get the screw extractor to grab onto the shaft (no threads) which was quite far below the level of the cortex. There was nothing I could get down into the "hole" to grab the screw with.

    I ended up redoing the fusion, using a small laminaspreader to get to the screw where it crossed the old joint line. I was able to distract enough to get a small kelly onto the shaft and unscrew it and remove it through the joint.

    Not the way I wanted to do it.

    The screw extractors work great when there are threads to grab onto. I've not had one of these "herbert" type screws break before and I think it's enough reason not to use them anymore if there isn't a way to deal with complications.

    Did you think of using a small burr and circumscribing the head of the screw?

    Hey Stanley.
    The head wasn't the problem, I got that out quickly.
    THe problem was the deep broken smooth shaft.

    Hey Steve,

    How about using a trephine, then packing the hole with bone chips?

    Regards,
