Lumbar radiculopathy, often called radicular back pain, refers to a nerve pinched in the lower lumbar or sacral spine with nerve pain radiating down one or both legs.
Lumbar radiculopathy, often called radicular back pain, refers to a nerve pinched in the lower lumbar or sacral spine with nerve pain radiating down one or both legs. Radicular back pain, often radiating down into the lower extremity, can arise from a wide variety of causes. Symptoms typically include radiating pain, numbness, tingling, weakness, and gait abnormalities, which can vary in severity.
Patients often present with a predictable pattern of symptoms that correspond to a specific dermatome or myotome. Management is typically conservative, at least initially, with surgical intervention typically reserved for refractory cases. This blog post seeks to review both lumbar radiculopathy and sciatica.
"Piriformis Syndrome and Variants–A Comprehensive Review on Diagnosis and Treatment." Journal of Spinal Surgery 8.4: 7-14.[/ref] "Lumbosacral radiculopathy" refers to a constellation of symptoms caused by the compression of the lumbosacral nerve roots . "Sciatica" specifically refers to pain in the distribution of the sciatic nerve. Although the terms sciatica and lumbosacral radiculopathy are often used interchangeably, they are technically distinct conditions.
Piriformis syndrome, which involves impingement of the sciatic nerve at the piriformis muscle, is considered a separate clinical entity. The symptoms of lumbar radiculopathy are secondary to various underlying etiologies, including degenerative disc disease, spondylolisthesis, facet joint pathology, and spinal stenosis. In rarer cases, it can be due to neoplasm, infection, or trauma.
Compression of the nerve root can occur at different locations, including within the thecal sac, as the nerve root exits the thecal sac in the lateral recess, as it traverses the neural foramina, or after the nerve root has exited the foramina.

If you are experiencing symptoms that may be related to lumbar radiculopathy, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
