Foraminal disc herniation is considered to be a part of extreme lateral disc herniations
which have relatively frequent occurrence of about 10% of all lumbar disc herniations. It
presents a different clinical features form that of useful intraspinal disc herniation in
that the prolapsed foraminal disc material compresses the nerve root st the level of disc
herniation.
Previously many operative procedures for foraminal disc herniations have been
introduced with the aids of various diagnostic methods. Interverterbral foraminotomy and
total facetectomy are still the most widely used options in treating extreme lateral
lumbar disc herination. But these technique could result in an unfortunate structural
disruption an frequently cause spinal instability and continued postoperative back pain.
Recently unilateral partial hemilaminectomy and resection of spinous process followed
by discectomy were performed in our hospital. For this procedure, paraspinal muscles
were elevated subperioseally and retracted bilaterally exposing the spinous process
preserving articular facet joint, then obliquely downward looking through intervertebral
foramen allowed direct visualization of prolapsed foraminal disc and compressed nerve
root. Thereafter prolapsed. foraminal disc could be successfully removed under direct
vision with the preservation of spinal stability.
When extraformainal disc coexisted, intertransverse approach was additionally
performed.
