  1. Spinal Cord Compression and Cauda Equina Syndrome

    Posted by Dr. Jack Sacks, Esq.on January 03, 2016

    There are approximately 12,000 new cases of spinal cord compression annually in the United States with the average age of victims being 39.5 years old. Causes of spinal cord compression include trauma (such as auto accidents, falls, sports injury, epidural injection), spinal abscess, tumor, hematoma or blood clot, ruptured or herniated disk, and spinal stenosis. . Early symptoms may include the start of loss of movement or feeling in the arms or legs, back pain, and the loss of bowel or bladder function or control. Spinal cord compression of sudden onset constitutes a medical emergency, as the longer the duration of symptoms before cord pressure relief is obtained by surgical intervention (laminectomy), the greater the chance of permanent injury. Diagnosis is by clinical exam and other testing such as X-ray, CT, and MRI. MRI is usually the most accurate study to detect spinal cord compression as details of both bony and soft tissue abnormalities in the spinal column may be visualized. MRI may also be the preferred study if spinal cord injury occurs during pregnancy as MRI offers reduced radiation exposure to the fetus. However, after an accident, traction devices to immobilize the spine and life support equipment may preclude the use of MRI.

    The spinal column is comprised in descending order of the cervical, thoracic, lumbar, and sacral areas. The actual spinal cord ends at the level of L-1. Below the level of L-1, the cord branches into a bundle of spinal nerve roots from L-1 through L-5 and S-1 through S-5 that resembles a horses tail referred to as the cauda equina. When the nerve roots of the cauda equina are compressed permanent neurogenic injury may occur. This may be referred to as cauda equina syndrome (CES). Causes of compression of these nerve roots include the same types of causes as listed above for spinal cord compression. Symptoms of early onset of cauda equina syndrome include numbness in the groin (saddle anesthesia), loss of bowel or bladder function or control, weakness in the legs, and absence of ankle reflexes. Early diagnosis and treatment of CES is important as the longer the duration of symptoms, the more likely permanent neurological injury will occur such as paralysis and incontinence. Cauda equina syndrome of sudden onset is a medical emergency and treatment generally involves surgical decompression of the affected nerve roots. A laminectomy may be performed to relieve pressure on the nerve root in cases where there is a herniated or ruptured disk, hematoma, abscess, or tumor.

    In spinal cord and nerve root compression cases involving sudden onset of neurological symptoms, medical malpractice may arise when there has been an unreasonable delay in diagnosis and prompt surgical intervention by the doctors or hospital. Allegations of medical malpractice may also include a failure to diagnose and treat a vertebral fracture of the neck or back that required traction or immobilization which was not performed, thereby allowing pathological movement that resulted in spinal cord compression.
