Causes
Lumbar radiculopathy occurs when there is compression of the nerves in the lower back. While nerve compression is the primary cause, there are several factors that can contribute to this condition. Traumatic injuries, bone spurs, herniated discs, and congenital defects are the most common causes of lumbar radiculopathy. These conditions can lead to damage in the discs, which in turn puts pressure on the nerve roots. It is worth noting that symptoms of lumbar radiculopathy typically appear in midlife and are often associated with the natural aging process. Men are more likely to experience symptoms in their 40s, while women may start experiencing symptoms in their 50s and 60s.
Diagnosis: Understanding Lumbar Radiculopathy
Getting a proper diagnosis for lumbar radiculopathy involves a thorough physical examination. Medical professionals employ different techniques and assessments to identify this condition, one of which is the straight leg or Lasègue test. This test is designed to put pressure on the sciatic nerve, helping to determine the presence of lumbar radiculopathy.
During the straight leg test, the clinician gently raises the patient’s leg into the air at an angle of about 30 to 60 degrees. The goal is to reproduce any pain or discomfort experienced by the patient. If the patient feels pain during this maneuver, it is considered a positive result, indicating the likelihood of lumbar radiculopathy.
