Some issues Dr. Christopher Gene Kalhorn, MD can help you with:

Hydrocephalus

Normally, the brain is bathed in a liquid called cerebrospinal fluid. This fluid cushions and nurtures the brain cells as it flows around and through the brain. Sometimes, cerebrospinal fluid does not get reabsorbed into the body properly, or a blockage in the brain can stop it from flowing. This causes a buildup of pressure called hydrocephalus. This condition affects a wide range of people, but it is much more prevalent among infants and older adults. Left untreated, hydrocephalus can cause uncomfortable symptoms, such as headaches and blurred vision, and eventually may cause brain damage.

Hydrocephalus is most often treated with an implanted device called a shunt. A shunt is a long, thin tube that is used to drain excess fluid. One end is placed within the brain. The tube runs under the skin, along the neck behind the ear, and to another part of the body where the fluid can be reabsorbed. Most often this is the abdomen, but the chest or other areas can also be used. Shunts have a valve that allows doctors to monitor and control the pressure within the brain. Insertion of a shunt is a surgical procedure that takes one to two hours. Incisions are made in the head and the abdomen, and the shunt is threaded into place before the openings are stitched closed.

In cases where hydrocephalus is caused by a blockage, a procedure called endoscopic third ventriculostomy, or ETV, may be performed. During this procedure, a surgeon makes a dime-sized hole in the skull and uses a thin tube with a camera on the end (called an endoscope) to see inside the brain. The surgeon punctures a hole in the floor of the third ventricle, a fluid-filled space within the brain. The hole provides an opening for cerebrospinal fluid to flow around the blockage, normalizing pressure. The entire procedure usually takes less than an hour and patients can often go home the following day. ETV can provide a permanent and safe alternative to a shunt, but it is only useful for patients whose hydrocephalus is caused by a blockage.

Spinal Cord Injury

Spinal cord injury medicine is a branch of medicine that treats damage to the spinal cord from an injury or a nontraumatic myelopathy, which is any disorder that affects the spinal area. The spinal cord is a section of nerve tissue protected by the vertebrae (spinal bones). Trauma to the spinal cord, typically caused by compression or bent vertebrae, prevents the body and brain from communicating. This can result in pain, loss of sensation, and impaired physical function and movement. Acute spinal cord injuries (SCIs) are a leading cause of permanent disability. Spinal cord injuries may develop from accidents or myelopathies, disorders that provoke spinal compression. Traumatic incidents such as falls, sports injuries, vehicle accidents, and bullet or stab wounds can cause an acute spinal cord injury.

Spinal cord injury medicine seeks to stabilize the spine and to alleviate the symptoms of spine damage. Practitioners of spinal cord injury medicine are called spinal cord injury specialists. Spinal cord injury medicine is an interdisciplinary field, meaning physicians of various specialties may be trained to treat spinal cord injuries.

Damage to the spinal cord may initially be diagnosed through X-ray, MRI, or CT scans. Patients can also undergo spinal exams to evaluate their sensory ability and strength. Injuries to the spinal cord can be complete (no feeling or sensation) or incomplete (some feeling or sensation remains). Conditions spinal cord injury medicine specialists may treat include:

Paralysis, such as paraplegia (loss of function in the legs), or quadriplegia (loss of function from the neck down)
Spine fracture or trauma, which can lead to impairment and/or significant pain
Spinal infections
Myelopathies, such as herniated disks, spinal tumors, and rheumatoid arthritis
Inflammatory diseases such as ankylosing spondylosis, and degenerative conditions like Lou Gehrig's disease (ALS)

Treatment for spinal cord injuries often involves surgery, either directly after an injury occurs or at a later date. Surgery for spine injuries is intended to ease spinal compression and stabilize the spine. Surgical procedures can involve shifting vertebrae, removing bone, or altering spinal placement with implantable devices. Patients with significant spinal trauma may require urgent surgical intervention.

Surgical treatments can be complemented by rehabilitative physical therapy to improve mobility. Spinal cord injury specialists also treat complications arising from a spinal injury, such as respiratory or bladder conditions. Some patients with spinal cord injuries may require lifelong treatment. Spinal cord injury specialists aim to help these patients successfully adjust and lead an improved quality of life. An emerging treatment for spinal cord injuries is neural prosthetics, which replicate patients' lost nerve function. Neural prostheses may be used as artificial body parts or assistive devices that patients may cognitively control. Other assistive devices include wheelchairs and scooters.

Spinal cord injury specialists may collaborate with physical therapists, radiologists, neurologists, urologists, and orthopedists.

Spinal Fusion

Spinal fusion is a surgical procedure to permanently join together two or more vertebrae, the bones in the spine. Certain spinal disorders can lead to instability and pain, and the idea behind spinal fusion is that fusing vertebrae together can both make them stronger and reduce motion, which can sometimes reduce pain.

There are several different types of spinal fusion surgery available, mostly depending on where a patient's pain is located and whether his or her surgeon will perform the procedure through the back, front, or side. In general, a fusion is performed by packing the vertebrae to be fused with grafted bone. This bone may be taken from the patient's hip, may be donated from a cadaver, or it may be a manufactured synthetic material. The bone is placed along the vertebrae, and sometimes, the disc that lies in between the vertebrae is removed and replaced with grafted bone. The bone material will grow and cement the two vertebrae together. After the bone graft is placed, the vertebrae are sometimes held in place with rods, screws, plates, or cages, depending on the weakness of the spine and needs of the graft.

Spinal fusion is a significant surgery and can take three to four hours or more. Recovery is typically two to four days in the hospital. After surgery, it is important to remember that the fusion takes time to grow from the bone graft. So, the actual fusion is not complete for several months. Patients will probably feel somewhat better right away, but it may take a while to feel the full effects of the fusion as the bone grows into place. In the meantime, doctors might have patients wear a brace to protect their spine and keep it properly aligned.

Spinal fusion is not used for all kinds of back pain. Changing the way the spine moves can lead to strain on the other joints in the back, and fusion is only performed when the benefits outweigh the risks. Some spine disorders that are treated with fusion include:

Curvature disorders, such as scoliosis and kyphosis
Degenerative disc disease
Spondylolisthesis, a disorder that causes vertebrae to slip over each other
Significant spinal fractures that cause instability
Weakened spine due to infection or tumor
Some cases of spinal stenosis, a narrowing of the spinal column
Chronic lower back pain (although the use of fusion to treat this is controversial)

Regardless of the diagnosis, there is always a possibility of 'failure' with spinal fusion, or of the surgery not fully solving the pain. This is more likely when fusion is used primarily to treat pain instead of structural problems. Patients can improve their chances of a successful outcome by stopping smoking, maintaining a healthy weight, moving their body every day, and following their doctor's instructions for any physical therapy that they are prescribed.
