The diagnosis of disc sequestration.

A Deburge, M Benoist, D Boyer

    Spine
    |July 1, 1984
    PubMed
    Summary

    Recognizing sequestrated disc herniation is crucial for successful chemonucleolysis. Irregular myelographic defects distant from the disc space suggest sequestration, guiding treatment decisions for spinal disc issues.

    Area of Science:

    • Neurosurgery
    • Radiology
    • Orthopedics

    Background:

    • Sequestration of a herniated disc is a significant factor in chemonucleolysis failure.
    • Early identification of sequestrated disc herniations is vital before enzymatic discectomy.

    Purpose of the Study:

    • To identify clinical and myelographic indicators of disc herniation sequestration.
    • To correlate surgical findings with preoperative clinical and myelographic signs.

    Main Methods:

    • Review of patient charts, myelograms, and surgical findings for 98 patients with operated disc herniations.
    • Correlation of three anatomic disc herniation types with preoperative clinical and myelographic signs.

    Main Results:

    • No specific clinical signs were identified for sequestration.
    • No pathognomonic myelographic features definitively indicated sequestration.
    • Irregular myelographic defects located away from the disc space raised suspicion for sequestration.

    Conclusions:

    • Clinical signs are unreliable for diagnosing sequestrated disc herniation.
    • Myelography showing irregular defects distant from the disc space is a key indicator for suspecting sequestration.
    • Accurate diagnosis of disc herniation type is essential for effective treatment planning.
