A herniated disk is defined as "an intervertebral disk in which the nucleus pulposus has protruded through surrounding fibrocartilage. This occurs most frequently in the lower lumbar region.".[1]
Diagnosis
History and physical examination
The presence of sciatica is associated with a herniated disk:[2]
- sensitivity = 95%
- specificity = 88%
On physical examination, a positive straight leg raise is associated with a herniated disk:[2]
- sensitivity = 80%
- specificity = 40%
Treatment
A randomized controlled trial of discectomy versus conservative care found the surgery led to quicker improvement, but there were no differences after one year.[3] The cost of surgery might be acceptable to some patients.[4]
