Abstract
Introduction and Aims: Lower back and/or leg pain is a symptom of a number of pathological conditions involving lumbosacral nerve roots. Disc herniation is one of the most common causes of LBP (after mechanical back pain). There is controversy regarding the progression of disc degeneration and/or lower back pain to symptomatic disc prolapse over time.
Method: The aim of the study was to determine the natural progression of patients with lower back pain/disc degeneration established clinically and on MRI to symptomatic disc herniation over three to six years. Total of 970 patients who had an MRI scan between January 1998 and September 2000 were included in the study. Information about disc pathology, level and number of discs involved were recorded from MRI scan reports. A short questionnaire was sent to all patients. It contained 10 questions regarding current status of pain and neurology, any treatment in form of back injection and operation, current occupation and smoking status.
Results: The collected data was analysed using standard statistics software (SPSS). The results will be discussed.
Conclusion: The information provided by this study will be useful in judging the natural progression of lower back pain and/or disc degeneration to a symptomatic prolapse intervertebral disc. It will also be useful in medico-legal cases where patients had pre-existing disc degeneration and subsequently developed disc herniation over time.
