[Incidence and characteristics of lumbar disk hernias in older patients]

Previous history, clinical findings, course and therapeutic outcome in 149 elderly patients with lumbar disk hernia were analyzed and compared with younger adult patients. 21% of all patients with lumbar disk hernia undergoing surgical treatment, and 25% under conservative treatment, were aged over 60 years. In these patients no history of low back pain is present in one third, the course is prolonged and motor deficits are more often encountered. Concomitant osseous narrowing (spinal stenosis, narrowed recessus lateralis) were present in 72% of this elderly group. Surgical complications are increased (34%) and are due to age-related diseases. Functional results are excellent after both conservative treatment and surgical therapy.
