What is Posterolateral Extradural Disc Decompression?
Posterolateral extradural disc decompression is a minimally invasive surgical technique for decompression of painful lumbar (lower back) discs. How does Posterolateral Extradural Disc Decompression work? Posterolateral extradural disc decompression involves the placement of a shaving instrument through a cannula (blunt hollow tube about the size of a small straw). This instrument extracts disc material through the cannula. Decompression occurs as the disc contracts. Contraction of the disc results in retraction of the disc bulge or herniation. Decompression of the disc reduces stretching forces that occur with tears of the annulus (rim of the disc). Because the nerves of supplying the disc are only located in the annulus, pain can be reduced by decreasing the stretch of the annulus. Which patients are candidates for Posterolateral Extradural Disc Decompression? • The presence of lower back pain, lower back pain with radiation in the extremities, or extremity pain that is likely seconda
