Hilibrand MD and Nahshon Rand MD Abstract Degenerative lumbar stenosis is a common cause of disabling back and lower extremity pain among older persons. The process usually begins with degeneration of the intervertebral disks and facet joints resulting in narrowing of the spinal canal and neural foramina. Associated factors may include a developmentally narrow spinal canal and degenerative spinal instability. Nonoperative management includes restriction of aggravating activities physical therapy and anti-inflammatory medications. If nonoperative treatment has failed surgical treatment may be appropriate. Decompression should be performed so as to address all clinically relevant neural elements while maintaining spinal stability. If instability is present autogenous intertransverse bone grafting is recommended. There may be an advantage to augmenting some of these procedures with internal fixation. Surgical success rates as high as 85 have been reported but may be compromised by inadequate decompression inadequate stabilization or medical comorbidities. Short-term follow-up data indicate that operative management provides more effective relief than nonoperative treatment but prospective studies comparing the effects of nonoperative and operative interventions on the long-term natural history of lumbar spinal stenosis are needed. J Am Acad Orthop Surg 1999 7 239-249 The earliest description of lumbar stenosis is attributed to Antoine Portal who in 1803 described toonarrow vertebral canals in hunchbacks with rickets. The concept of acquired lumbar spinal stenosis was popularized in the 1950s by Verbiest. Since then advances in diagnostic and therapeutic modalities coupled with the extension of life expectancy have increased the rate of detection and subsequent operative intervention. The general incidence of degenerative lumbar spinal stenosis ranges from 1 to 8 .2 Symptoms typically develop in the .
