Spontaneous regression of herniated nucleus pulposus
AJR. American Journal of Roentgenology
|August 1, 1985
Summary
Spontaneous regression of herniated lumbar discs (a condition where the disc material moves out of place) was observed in 11 patients. Symptoms resolved in all symptomatic patients, suggesting a potential for natural healing.
Area of Science:
- Neurosurgery
- Radiology
- Orthopedics
Background:
- Herniated nucleus pulposus (HNP) is a common cause of low back pain.
- Spontaneous regression of HNP has not been previously documented.
- Conservative therapy is the usual management for symptomatic HNP.
Purpose of the Study:
- To report the first documented cases of spontaneous regression of herniated lumbar discs.
- To evaluate the clinical outcomes in patients with regressed HNP.
Main Methods:
- Retrospective review of 11 patients with herniated lumbar discs.
- Follow-up computed tomography (CT) scans to assess disc regression.
- Clinical assessment of symptoms attributed to HNP.
Main Results:
- Unequivocal regression or disappearance of herniated lumbar discs was observed in all 11 patients on follow-up CT.
- Two patients with herniated discs were asymptomatic.
- Symptoms resolved or diminished in all nine symptomatic patients.
Conclusions:
- Spontaneous regression of herniated lumbar discs is a possible phenomenon.
- Further investigation with frequent follow-up CT scans is warranted to determine the frequency of HNP regression in patients undergoing conservative therapy.
