Frequently Asked Questions

What is an orthopaedic surgeon?
An orthopaedic surgeon is a medical doctor who has received up to 14 years of education in the diagnosis, treatment, rehabilitation, and prevention of injuries and diseases of the musculoskeletal system (bones and joints, muscles, ligaments, tendons, and cartilage). 

Some orthopaedic surgeons practice general orthopaedics, while others specialize in treating certain body parts such as the foot and ankle, hand and wrist, spine, knee, shoulder, or hip. Some orthopedists may also focus on a specific population such as pediatrics, trauma, or sports medicine.

What is the difference between x-rays, MRI, and CT scan?
X-rays are provided in our office. They are a type of radiation, and when they pass through the body, dense objects such as bone block the radiation and appear white on the x-ray film, while less dense tissues appear gray and are difficult to see. X-rays are typically used to diagnose and assess bone degeneration or disease, fractures and dislocations, infections, or tumors.

Organs and tissues within the body contain magnetic properties. MRI, or magnetic resonance imaging, combines a powerful magnet with radio waves (instead of x-rays) and a computer to manipulate these magnetic elements and create highly detailed images of structures in the body. Images are viewed as cross sections or “slices” of the body part being scanned. There is no radiation involved as with x-rays. MRI scans are frequently used to diagnose bone and joint problems.

A computed tomography (CT) scan (also known as CAT scan) is similar to an MRI in the detail and quality of image it produces, yet the CT scan is actually a sophisticated, powerful x-ray that takes 360-degree pictures of internal organs, the spine, and vertebrae. By combining x-rays and a computer, a CT scan, like an MRI, produces cross-sectional views of the body part being scanned. In many cases, a contrast dye is injected into the blood to make the structures more visible. CT scans show the bones of the spine much better than MRI, so they are more useful in diagnosing conditions affecting the vertebrae and other bones of the spine.

What is a cortisone injection?
Cortisone is a steroid that is produced naturally in the body. It is the strongest anti-inflammatory. Synthetically-produced cortisone can also be injected into soft tissues and joints to help decrease inflammation. While cortisone is not a pain reliever, pain may diminish as a result of reduced inflammation. In orthopaedics, cortisone injections are commonly used as a treatment for chronic conditions such as bursitis, tendonitis, and arthritis.

What is arthroscopic surgery?
Arthroscopic surgery is one of the most common orthopaedic procedures performed today. Through the use of small instruments and cameras, an orthopaedic surgeon can visualize, diagnose, and treat problems within the joints. 

One or more small incisions are made around the joint to be viewed. The surgeon inserts an instrument called an arthroscope into the joint. The arthroscope contains a fiber optic light source and small television camera that allows the surgeon to view the joint on a television monitor and diagnose the problem, determine the extent of injury, and make any necessary repairs. Other instruments may be inserted to help view or repair the tissues inside the joint.

What is joint replacement surgery?
Joint replacement surgery is performed to replace an arthritic or damaged joint with a new, artificial joint called a prosthesis. The knee and hip are the most commonly replaced joints, although shoulders, elbows and ankles can also be replaced. 

Joints contain cartilage, a rubbery material that cushions the ends of bones and facilitates movement. Over time, or if the joint has been injured, the cartilage wears away and the bones of the joint start rubbing together. As bones rub together, bone spurs may form and the joint becomes stiff and painful. Most people have joint replacement surgery when they can no longer control the pain with medication and other treatments, and the pain is significantly interfering with their lives.
