Chemonucleolysis Versus Percutaneous Automated Discectomy Using Nucleotome.
Kyung Woo Park, Kyung Gi Cho
Department of Neurosurgery, Presbyterian Medical Center, Jeonju, Korea.
Authors reviewed the radiographs and medical records of 85 consecutive patients who underwent chemonucleolysis and percutaneous automated discectomy between May, 1986 and Feb. 1988 at the Dept. of Neurosurgery, Presbyterian Medical Center, Chon-ju, Korea. Among 85 consecutive patients, 48 patients underwent Chemonucleolysis and others underwent PAD using nucleotome. The results showed relatively low success rate of 60.3% in chemonucleolysis and 62.2% in PAD. However in PAD using nucleotome, the favorable selection criteria to define the higher successful rate(70-87.5%) included; 1) in young age group under 30. 2) in the group of no motor and sensory deficits. 3) in spine CT findings, which showed mild disc protrusion and no focal central disc bulging pattern. The better results will be obtained when the careful selection of patients is done and operated technique is more developed.
Key Words: Herniated lumbar disc; Chemonucleolysis; Percutaneous automated discectomy
