Abstract
Background: Until now, numerous treatment options for the percutaneous intradiscal procedures(chemonucleolysis, auto- mated percutaneous lateral discectomy, intradiscal electrothermal therapy) in patients with lumbar disc herniation have been evolved. Among them, nucleoplasty has gained popularity for its simple manipulation and immediate effects. Nucleoplasty ablates, coagulates and decompresses the nucleus pulposus by way of high-density plasma field rather than by way of high thermal energy. Authors intended to describe the effects and technical details of nucleoplasty from 1 year follow up.
Methods
From August 2001 to December 2002, authors performed nucleoplasty for 74 consecutive patients(81 levels) and evaluated 1 year result according to Macnab criteria. Intraoperative discogram was prerequisite for determination of the precise causative level.
Results
Male was outnumbered female by 43 to 31 and age was ranged from 16 to 68 years old(mean: 33.9). Procedures were performed at single level in 67 cases and at two levels in 7 cases. The L4-5 level was the most commonly involved. According to Macnab's criteria, excellent and good outcome was achieved in 65 patients(87.8%), and fair and poor outcome was in 6(8.2%) and 3(4.0%) patients, respectively.
Conclusion
Nucleoplasty in patients with lumbar disc herniation showed successful results after 1 year of follow-up. Howe- ver, data collection with respect to the lengthening of population number and follow-up span, and refinement of strict inclusion/ exclusion criteria are necessary in near future.
