Percutaneous laser nucleotomy (PLN) has recently been utilized for many medical faculties of lumbar disc herniation. The post-operative course of PLN is known to be unclear. This paper reports the results of operational treatments for lumbar disc herniation, which were performed by PLN but ineffective in other hospitals.
The subjects consisted of 6 cases (5 males and 1 female, aged 21-52 years). Their preoperative and postoperative symptoms were compared, using the JOA score and the Hirabayashi's scoring system; we examined the possible cause of ineffective PLN from preoperatives test and operational findings.
The JOA score was significantly improved, and the improvement rate according to Hirabayashi's scoring system was above 80% for all these cases. Lumbar disc herniation descending down from the disc level was observed in 5 of these 6 cases and was regarded as partly responsible for ineffective PLN.
