M54.18

Clinical Causes: Herniated or bulging discs in the lower lumbar or sacral spine Degenerative disc disease leading to nerve compression Spinal stenosis (narrowing of the spinal canal in the sacral area) Trauma or injury to the lower back or pelvis Tumors or growths impinging on nerve roots Infections causing inflammation around nerve roots Congenital anomalies affecting spinal structure Spondylolisthesis (slippage of one vertebra over another)

Key Symptoms: Pain in the lower back region, often radiating to the buttocks or legs Numbness or tingling sensations in the buttocks, thighs, or groin area Weakness in the legs or feet Loss of reflexes in the lower limbs Difficulty with bowel or bladder control in severe cases Muscle spasms or cramping in the affected regions Sensory disturbances such as burning or stabbing pain

Diagnosis Path: Diagnosis typically involves a comprehensive medical history and physical examination focused on neurological function. Imaging tests are crucial for confirming the presence of nerve root compression. These may include: - Magnetic Resonance Imaging (MRI) to visualize soft tissues and nerve roots - Computed Tomography (CT) scans for detailed bone imaging - Nerve conduction studies or electromyography (EMG) to assess nerve activity The healthcare provider may also perform specific neurological tests to evaluate reflexes, muscle strength, and sensory responses.

Treatment Protocols: Treatment options aim to alleviate symptoms and address the underlying cause of nerve compression. Common approaches include: - Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief - Physical therapy to strengthen supporting muscles and improve flexibility - Rest and activity modifications to reduce nerve irritation - Epidural steroid injections to reduce inflammation around nerve roots - Use of assistive devices, such as braces or supports, for stability - In severe or persistent cases, surgical interventions such as discectomy, laminectomy, or nerve decompression may be necessary to relieve pressure on the affected nerve roots. Management plans should be tailored to individual patient needs and guided by a healthcare professional experienced in spinal disorders.
