Spinal Cord Injury
Spinal Cord Injury
The spinal cord is very sensitive to injury. Unlike other parts of your body, the spinal cord does not have the ability to repair itself if it is damaged. A spinal cord injury occurs when there is damage to the spinal cord either from trauma, loss of its normal blood supply, or compression from tumor or infection.
Types of Injuries
Complete: If almost all feeling (sensory) and all ability to control movement (motor function) are lost below the spinal cord injury.
Incomplete: If you have some motor or sensory function below the affected area.
CERVICAL (NECK) INJURIES
When spinal cord injuries occur in the neck area, symptoms can affect the arms, legs, and middle of the body. The symptoms may occur on one or both sides of the body. Symptoms can also include breathing difficulties from paralysis of the breathing muscles, if the injury is high up in the neck.
Cervical Herniated Disc
This type of cervical spine injury happens when the soft spinal discs bulge or rupture out of the spinal canal and put pressure on nearby nerve roots or the spinal cord. The culprit is usually some type of sudden force. Cervical Disc Degeneration
Over time, wear and tear on the cervical spine can injure it and cause the discs in the cervical spine to degenerate. The degeneration process can be exacerbated by a fall or twisting injury to the neck.
THORACIC (CHEST LEVEL) INJURIES
When spinal injuries occur at chest level, symptoms can affect the legs. Injuries to the cervical or high thoracic spinal cord may also result in blood pressure problems, abnormal sweating, and trouble maintaining normal body temperature.
This injury is very common in contact sports such as football and rugby. It most commonly occurs as a result of a blow to the ribs.
Scheuermann’s disease (Osteochondrisis)
This is the most common cause of pain in the thoracic spine in adolescents, especially boys. It is a hereditary back disease in which the back becomes rounded due to the bodies of the vertebrae becoming wedged shaped.
Scoliosis (Curvature of the spine) This is a curvature of the spine in a sideways direction which causes the spine to be S-shaped. Symptoms with scoliosis are not always present. Symptoms include complications due to muscle weakness and joint “looseness” on the convex side and muscle tightness and spasm with joint tightness on the concave side.
LUMBAR SACRAL (LOWER BACK) INJURY
When spinal injuries occur at the lower back level, symptoms can affect one or both legs, as well as the muscles that control the bowels and bladder.
Non-specific Low Back Pain (NSLBP) Low back pain can be caused by structures being too tight (hypo-mobility) or too loose (hyper-mobility). The pain producing structures in the lumbar spine include the vertebra, the facet joints (links two vertebra together in your spinal column), intervertebral disc, ligaments, nerves and their protective coverings, muscles and their attachments.
Intervertebral Disc Degeneration / Sciatica
The intervertebral discs are composed of a soft, inner nucleus pulposus surrounded by a tough fibrous outer ring, the annulus fibrosus. With trauma and / or ageing, the annulus fibrosus can weaken and thin (disc degeneration or herniation), particularly with the repetitive combination of bending forwards while rotating the trunk i.e. lifting.
Spinal Canal Stenosis
Another commonly encountered cause of Lower Back Pain is spinal canal stenosis. It is a condition that is rare in young and middle-aged athlete’s, but may be seen occasionally in older athletes. The condition is caused by arthritic degeneration of the spine, resulting in the vertebra, facet joints, and ligaments which surround the spinal nerves of the spinal cord to become enlarged. In this manner, these structures may compress one or several spinal nerves, causing LBP, leg pain, and leg numbness while walking.
Signs and Symptoms:
- Loss of movement
- Loss of sensation, including the ability to feel heat, cold and touch
- Loss of bowel or bladder control
- Exaggerated reflex activities or spasms
- Changes in sexual function, sexual sensitivity and fertility
- Pain or an intense stinging sensation caused by damage to the nerve fibers in your spinal cord
- Difficulty breathing, coughing or clearing secretions from your lungs
- Extreme back pain or pressure in your neck, head or back
- Weakness, incoordination or paralysis in any part of your body
- Numbness, tingling or loss of sensation in your hands, fingers, feet or toes
- Loss of bladder or bowel control
- Difficulty with balance and walking
- Impaired breathing after injury
- An oddly positioned or twisted neck or back
Spinal Decompression Surgery
Spinal decompression surgery is a general term that refers to various procedures intended to relieve symptoms caused by pressure, or compression, on the spinal cord and/or nerve roots. Bulging or collapsed disks, thickened joints, loosened ligaments and bony growths can narrow the spinal canal and the spinal nerve openings (foramen), causing irritation.
Discectomy is a surgery to remove all or part of a cushion that helps protect your spinal column. These cushions, called disks, separate your spinal bones (vertebrae).
Minimally invasive spine surgery
Minimally invasive spine surgery uses very small surgical incisions (often less than one inch) and specially designed surgical tools to treat spinal disorders. Because minimally invasive surgery is performed through small tubes, there is little disruption of normal structures. This reduces postoperative pain, speeds recovery, and leads to shortened hospital stays. Many minimally invasive spine procedures can be performed on an outpatient basis.
Foraminotomy Foraminotomy is a surgery that widens the opening in your back where nerve roots leave your spinal canal. You may have a narrowing of the nerve opening (foraminal stenosis).
Spinal fusion is a surgery to join together two bones (vertebrae) in the spine. Fusion permanently joins two bones together so there is no longer movement between them. Spinal fusion is usually done along with other surgical procedures of the spine.
Vertebroplasty is performed by a radiologist, without surgery, and involves inserting a glue-like material into the center of the collapsed spinal vertebra to stabilize and strengthen the crushed bone. The material is inserted through anesthetized skin with a needle and syringe, entering the midportion of the vertebra under the guidance of specialized X-ray equipment. Once inserted, the material hardens to form a cast-like structure within the broken bone. Relief of pain comes quickly from this casting effect, and the newly hardened vertebra is then protected from further collapse.
The rehabilitation process following a spinal cord injury typically begins in the acute care setting. Physical therapists, occupational therapists, social workers, psychologists and other health care professionals typically work as a team under the coordination of a physiatrist to decide on goals with the patient and develop a plan of discharge that is appropriate for the patient’s condition.
