Endoscopically assisted open removal of laterally herniated lumbar discs.
BACKGROUND
Adequate treatment of laterally herniated lumbar discs presents a surgical challenge. All fragments compressing the nerve root should be removed without destruction of the overlying facet joint. To accomplish this goal many techniques have been proposed, each with specific limitations.


METHODS
In a small group of patients we have used a small malleable endoscope to assist in the removal of laterally herniated discs. Via a small laminotomy, the nucleus was removed in a standard manner and then the lateral disc material removed under direct endoscopic visualization.


RESULTS
There were no operative complications and the nerve root was visualized and decompressed in all patients. There has been no recurrence of pain or development of spondylolisthesis.


CONCLUSIONS
This technique negates removal of portions of the facet joint and provides adequate nerve root decompression.
