  • Interbody fusion device with anti-rotation features
    Patent number: 7192446
    Abstract: An improved interbody fusion device incorporating anti-rotation features to inhibit accidental screwing or unscrewing of the fusion device in an intervertebral disc space. One such feature is a thread pattern having a crest diameter that increasingly tapers from a smaller diameter at the insertion end to a larger diameter at the opposite end making further advancement of the thread into the bone more difficult. Another feature is a thread cut out on the trailing edge of the thread, creating a barb which has a tendency to inhibit unscrewing. These features may be used alone or in combination for an improved interbody fusion device.
    Type: Grant
