Abstract

The authors reviewed the radiographs and medical records of 134 consecutive patients who underwent chemonucleolysis and automated percutaneous lumbar discectomy(APLD) between March 1990 and December 1994 at our institute. Among the 34 consecutive patients, 90 patients underwent chemonucleolysis and the other remaining patients underwent APLD using a nucleotome. The results are summarized as follows: 1) In both groups, predominent patients were of young age and males. 2) The most common lesion was in L4-5 interspace in both groups 3) The posteior lateral type showed high incidence in APLD group. 4) The results were better in the younger age group and when spinal CT demonstrated posterior lateral type in both groups. 5) The results showed relatively good success rate of 84.4% in chemonucleolysis group and 88.6% in APLD group. 6) Better results can be anticipated when patients are carefully selected and operated on with a higher skillful technique.
