Some issues Dr. Duncan L. McKellar JR., MD can help you with:

Replacement Arthroplasty (Joint Replacement)

Joint replacement, sometimes also called arthroplasty, is an option when a joint becomes severely damaged by disease or injury. The damaged cartilage of the joint is surgically removed, the ends of the bones in the joint are resurfaced, and a prosthetic is installed. Most prosthetic joints are made of a metal piece that fits into a plastic sleeve so that they glide smoothly. A joint replacement increases stability in the damaged area and decreases pain. The hip and knee are the two joints most commonly replaced, but joint replacement can also be performed on the ankle, shoulder, elbow and even fingers.

Although joint replacement is one of the safest and most reliable medical procedures available, it is still a major surgical procedure. All surgical procedures carry risks, such as infection or blood clots. For this reason, doctors try to help their patients avoid surgery for as long as they can. Taking arthritis medications, losing weight, avoiding high impact sports such as running, taking supplements such as glucosamine or chondroitin, or having joint injections may allow a patient to enjoy life without the need for surgery.

After having joint replacement surgery, patients can expect some pain the first few days as they recover. Physical therapy is an important part of recovery, and it can decrease complications and increase future mobility. As soon as possible, returning to low impact sports such as swimming, walking or biking can stretch and heal the new joint. A prosthetic joint can last 15 - 20 years and cannot be further damaged by degenerative diseases such as arthritis, so once it is done patients should be pain-free for many years.

Robotic Surgery

Robotic surgery is a type of minimally invasive surgery, using a tiny opening to get inside the body instead of making a large cut. It uses small tools attached to a thin robotic arm, which is controlled by the surgeon. Robotic surgery may be referred to by the specific kind of robot that is used. The most advanced robot currently in use is called the da Vinci, and surgery using it is sometimes called da Vinci surgery.

There are many benefits to robotic surgery, both for the patient and the surgeon. Robotic surgery allows for more precise movements and increased control during very delicate surgical procedures. This makes performing surgery accurately much easier for surgeons and reduces fatigue. The smaller 'hand' of the robot can enter the body via a much smaller opening, which reduces the risk of infection and scarring and leads to a faster recovery. The robotic hands also contain tiny moveable cameras among their tools, giving surgeons a much closer view of the procedure than would be possible with traditional surgery.

Trigger Finger Surgery

"Trigger finger," or stenosing tenosynovitis, is a condition where the tendons at the base of a finger become irritated and swollen. They may develop small lumps similar to scar tissue. As the swollen, bumpy tendons pass through their sheath, a tunnel of connective tissue that holds them in place, they become stuck. The finger gets frozen in a bent, curled position. If forced, the finger can be straightened. When this happens, the stuck tendons slip through all at once, often causing a popping or clicking noise. Many cases of trigger finger respond well to non-surgical treatments such as NSAIDs, splints, or injected steroids. However, in severe cases, surgery may be necessary.

During trigger finger surgery, the tendons at the base of the affected finger are identified and the sheath is opened up, allowing the tendons to move freely without getting stuck. This can be done through a tiny incision in the palm, or even without an incision at all, using the tip of a needle. Most people are able to move their fingers normally, bending and straightening their finger without catching or popping, right away after surgery. Although patients may have some pain and stiffness as they heal, recovery is quick.
