Percutaneous lumbar nucleotomy.

We performed 66 percutaneous lumbar nucleotomies (PLN) in 63 patients from October 1984 to March 1990. The patients (42 male patients, 21 female patients) ranged in age from 13 to 73 years (average, 36.8 years). Postoperative observation ranged from 6 months to 5 years and 11 months (average, 2.0 years). Pre- and postoperative discograms were reviewed. Fifty-one patients (79.7%) were judged to have successful results: They were able to return to gainful employment and to their preinjury level of activity. Six patients (9.4%) were judged to have unsuccessful results, and they required more radical surgical procedures. PLN was not effective for the patients with extremely severe positive SLR or agonizing leg pain.

Extraforaminal disc herniation.

Atypical disc herniation, especially extra foraminal disc herniation (EFDH), is apt to be overlooked, because myelography and peridurography can give false positive and false negative findings. Eleven cases of EFDH were diagnosed since 1975, and all were confirmed by operative treatment. This number is a very small percentage of the total, but if these cases had not been diagnosed correctly, the results of surgery would have been poor. Selective lumbosacral radiculography and nerve root block techniques are very useful in determining the nerve root involved. Discography is an excellent diagnostic technique for finding the relationship between the nerve root and hernia mass. Extra foraminal disc herniation must be kept in mind as a cause of lumbar radiculopathy.
