S34.3

Clinical Causes: Severe lumbar disc herniation pressing on the nerve roots Trauma from falls, car accidents, or direct blows to the lower back Spinal stenosis causing narrowing of the spinal canal Tumors or cysts compressing the nerve roots Infections affecting the spinal cord and nerve roots Invasive spinal procedures or surgeries resulting in nerve injury

Key Symptoms: Severe lower back pain that may radiate into the legs and groin Weakness in the legs or feet, potentially affecting walking or mobility Numbness or tingling sensations in the saddle area (genital region and inner thighs) Loss of sensation or decreased sensation in the pelvis area Difficulty controlling bladder and bowel functions, including incontinence or retention Reduced or absent reflexes in the lower limbs Possible paralysis of lower extremities in severe cases

Diagnosis Path: Diagnosis of cauda equina injury involves a combination of clinical evaluation and diagnostic imaging. Healthcare providers typically perform a detailed neurological exam to assess motor and sensory function, reflexes, and autonomic control of bladder and bowel. Magnetic resonance imaging (MRI) is the preferred method for visualizing the lumbar spine and identifying areas of compression or injury to the nerve roots. Additional tests could include CT scans or myelography if MRI is contraindicated.

Treatment Protocols: Treatment strategies depend on the severity and cause of the injury. Urgent surgical intervention, such as decompression laminectomy, is often necessary to relieve pressure on the nerve roots and prevent further damage. Conservative management may include pain control, physical therapy, and rehabilitation to restore function and mobility. In cases where bladder or bowel functions are affected, specialized interventions and support may be required. Early diagnosis and intervention are critical to optimizing outcomes.
