Prospective randomized trial of chemonucleolysis compared with surgery for soft disc herniation with 1-year, intermediate, and long-term outcome: part II: the radiological outcome.

Study Design: A prospective consecutive series of 100 patients computer randomized into 2 groups to have treatment by either chemonucleolysis or surgery.

Objective: To compare the radiological findings preoperatively with the clinical outcome between the groups at 1 year, 10 to 13, and 24 to 27 years of follow-up.

Summary Of Background Data: Chemonucleolysis was introduced in 1964 and became widely used.
