Abstract
Jensen R, Bliddal H, Hansen SE, Karle A, Jensen H, Christensen TH, Bay H. Changes in CT Scans in the Acute Phase and after Long-term Observation. Scand J Rheumatol. 1993; 22: 30–34.
No significant changes were noted in the CT-scan before and after 14 days of conservative therapy for low-hack 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).
