The outcome for a patient following surgery to excise a herniated lumbar disc can be predicted based on a preoperative questionnaire. The questionnaire is of predictive value if the patient has not previously undergone lumbar spine surgery. The questionnaire is not designed to encompass candidates for other types of lumbar spine surgery such as decompression laminectomy or fusion. This was developed at the Low Back Pain Clinic at the Crozer-Chester Medical Center in Pennsylvania.
