Some issues Dr. Jordi X. Kellogg, MD can help you with:

Biopsy

A biopsy is a procedure performed to remove a small sample of cells for testing. The cells are examined in a laboratory to check for disease, or sometimes to see how badly a known disease is affecting them. Biopsy can be performed on any part of the body.

Although biopsy is most often associated with cancer, it can also be used to check for other diseases, such as infections. A biopsy sample can be scraped, cut, collected with a needle, taken with a machine that punches out a tiny piece, or removed with the tiny tools in an endoscope.

In most cases, a biopsy is a simple outpatient procedure. Depending on the procedure, patients may need to stop taking certain medications beforehand, such as blood thinners. It is important for patients to tell doctors if they are pregnant, as certain biopsies require the use of x-rays to guide the needle to the right location. There is usually very little pain associated with a biopsy. Patients will have to wait a few days to hear the results.

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.

Spinal Osteotomy

Spinal osteotomy is a surgical procedure used to treat significant spinal deformity, sometimes as part of a spinal reconstruction. During spinal osteotomy, one or more pieces of bone are removed. This creates a curve, allowing for proper realignment of the spine.

There are three major types of spinal osteotomy. In order of amount of bone removed, they are:

Smith-Peterson osteotomy or SPO, which offers a small amount of correction and is often performed on multiple levels of the spine. This procedure is the least invasive, removing a small piece of bone from the back of the vertebra.
Pedicle subtraction osteotomy or PSO, which is often used in the lower back for the treatment of flatback syndrome, a condition in which the lower spine loses its natural curve. A slice or wedge of bone going through the entire vertebral column is removed, allowing more movement for repositioning.
Vertebral column resection or VCR, which is the most involved spinal osteotomy surgery. It is almost always performed as part of a spinal reconstruction. One or more entire vertebrae are removed, and the spine is fused into place with rods or screws.

After surgery, it is common to stay in the hospital for several days. Recovery can be slow, and patients will likely need help doing regular activities for the first few weeks. Lifting objects and bending or twisting, such as when getting out of bed or into a car, will be extremely difficult at first. Physical therapy can help patients heal and move. Most daily activities can be resumed after six weeks, and most patients return to full activity, including playing certain sports, within a year.

Although the recovery from spinal osteotomy can be significant, it can be quite effective at reducing pain. Correcting a spinal deformity can also improve appearance and self-esteem, increase balance, and improve stability when moving.
