The examination of the lumbar spine is essential for patients with axial back pain, claudication, leg pain, neurological deficits in the lower extremities, or dysfunction of the bowel and/or bladder. Considering all these symptoms may stem from disorders related to the lumbar spine, spinal canal, or nerve roots, questions about these symptoms should be incorporated into the medical history evaluation. It is imperative to exclude acute presentation (symptoms and signs) indicative of cauda equina syndrome, particularly in an emergency context; a thorough comprehension of the risks linked to lumbar spinal canal compression is crucial. If the patient exhibits radicular symptoms (pain, sensory changes, or weakness in a nerve root distribution), it is essential for the examiner to ascertain the affected nerve root during the history and physical examination. Ultimately, consistently inquire about relevant systematic symptoms to exclude the possibility of a tumor or infection (such as nocturnal discomfort, fever, chills, diaphoresis, or unexplained weight loss).
