Surgery for herniated lumbar disc disease: factors influencing outcome measures. An analysis of 403 cases.
The records of 403 patients treated for herniated lumbar disc disease were analysed in a retrospective observational study in order to verify how three outcome measures, i.e., satisfaction with the outcome of surgery, the degree of return to activities of daily living including work (ADL), and duration of interruption of ADL, may be influenced by clinical variables. Age, type of disc herniation, radiological evidence of recurrence (radiological recurrence), and need for a second surgical operation for disc herniation (surgical recurrence) were found to be significantly related to the patient's satisfaction with the outcome of surgery at follow up. Satisfaction with the outcome of surgery was not found to depend on the interval between clinical onset and radiological diagnosis, or on the timing of surgery. The degree of return to ADL was found to be significantly related to age, surgical recurrence, type of disc herniation, and timing of surgery. The results of the present study suggest that age and type of disc herniation are among the most important factors to consider when deciding whether or not to operate on a patient for herniated lumbar disc and that return to ADL after surgery is closely correlated with disc disease recurrence.
