Caudal stenosis refers to the narrowing of the lower spinal canal, typically in the lumbar or sacral region, which compresses the spinal nerves. This condition can result from degenerative changes, congenital abnormalities, herniated discs, ligament thickening, or spinal trauma. Patients often experience lower back pain, leg numbness, weakness, or difficulty walking. In severe cases, bladder and bowel dysfunction may occur. Early diagnosis is crucial to prevent progressive neurological deficits and ensure timely intervention. Understanding the anatomy and underlying cause of the stenosis allows neurosurgeons to plan precise and effective treatment strategies.
Diagnosis involves a detailed neurological examination and imaging studies such as MRI or CT scans to assess the degree of canal narrowing and nerve compression. Electromyography (EMG) or nerve conduction studies may be used to evaluate nerve function. Accurate assessment helps differentiate caudal stenosis from other causes of lower back pain and guides appropriate surgical or non-surgical management.
Mild cases of caudal stenosis may be managed with physical therapy, medications, and lifestyle modifications. Severe or progressive cases often require surgical intervention, such as decompressive laminectomy, laminotomy, or minimally invasive endoscopic decompression. Surgery aims to relieve nerve compression, restore normal spinal canal dimensions, and alleviate pain and neurological symptoms while preserving spinal stability.
Postoperative recovery includes pain management, physiotherapy, and gradual mobilization. Rehabilitation focuses on strengthening muscles, improving flexibility, and restoring normal posture and function. Follow-up imaging ensures adequate decompression and monitors for recurrence or complications. With proper care, patients experience significant pain relief, improved mobility, and enhanced quality of life.
