Abstract:
No significant changes were noted in the CT-scan before and after 14 days of conservative therapy for low-back pain. Twenty of 33 patients had a disc herniation diagnosed on CT, and of these 18 patients were re-scanned after two weeks. Twelve patients were subsequently treated surgically, and of the remaining 8 patients 6 were re-scanned after 18 months. At this time the disc herniation had diminished significantly and was located in a more median position. In the 8 conservatively treated patients, the pain score at follow-up was related to the original size of the herniation (r = 0.72, p < 0.05).
