Lumbar microdiscectomy in the elderly patient

This study retrospectively analysed 60 patients who had undergone microsurgical lumbar discectomy at an age of > or = 60 years. The results were compared with those obtained in 44 discectomy patients who were operated on during the same study period, but not selected for age. Sixty-five operations were performed on the elderly group and 49 on the age comparison group. Patients were scored for pain relief in a short-term follow-up (2 months) using office visit records. Long-term follow-ups [mean 6.5 years (elderly) vs 8.8 (comparison) years], obtained by a mailed questionnaire, quantified leg and back pain and scored success in return to normal activities (RTA) and satisfaction with the results of surgery. In the short-term, overall pain relief was highly successful and not significantly different in both group [94% (elderly), 98% (comparison)]. Long-term follow-up yielded the following successful outcomes (elderly, comparison groups): leg pain relief (91%, 86%), back pain relief (76%, 76%), RTA (68%, 87%), and satisfaction (81%, 91%). As with other pre- and postoperative parameters, these differences were not statistically significant. As the proportion of older individuals continues to rise in developed countries, physicians are increasingly faced with geriatric patients whose symptoms are caused by herniated lumbar discs. The present study indicates that microsurgical discectomy for relief of this condition can be performed safely and effectively on these older patients.
