Conference paper


Follow-up CT of 106 pathological disks in 92 patients at a mean interval of 14 months after the initial examination revealed a strong association between the evolution of disc protrusions and clinical results, with a decrease in size of the majority of protrusions in successfully treated patients, whereas the others essentially remained unchanged (P< 0.0001). A significantly higher proportion of large protrusions diminished as compared to the smaller ones (P< 0.0001). Diffuse disc bulges were associated with a poor outcome and never regressed. There was a lower incidence of diminution of the central protrusions compared to other locations. Patients with normal disc spaces at the initial examination had better outcome than those with disc space narrowing. Only occasionally was a reduction of the disc space observed at follow-up.
