What is Orthopedics?

Orthopedics is a medical specialty that focuses on the diagnosis and treatment of conditions, disorders, and injuries of the muscles, bones, joints, tendons, ligaments, and nerves. A doctor specializing in orthopedics is called an orthopedic surgeon (or orthopedist).

Recently a friend had a bone density scan, and I’m wondering if I need one. What is a bone density scan?

A bone density test helps diagnosis osteoporosis, which causes weakening of the bones, and can ultimately results in fractures. Years ago, osteoporosis could only be detected after a person’s bone broke. However, with a bone density test, it’s now possible to know your individual risk of breaking bones before one breaks.

The test uses X-rays to measure the amount of calcium and other bone mineral packed into the segment of bone. Common areas we test include the spine, hip, and forearm.

Can you tell me about the pros and cons of a cortisone injection?

Cortisone is a steroid produced naturally in the body. Synthetically produced cortisone can also be injected into soft tissues and joints to help decrease inflammation. Cortisone is not a pain reliever, though your pain may diminish as a result of reduced inflammation after an injection. In orthopedics, cortisone helps treat chronic conditions such as bursitis, tendinitis, and arthritis by reducing swelling, pain, and joint stiffness.

One thing you can expect above all else is trust—your trust in us, and our trust in you and your body. As your team, we focus on proactive decisions built to support your physical health. Rather than feeling stuck in past and present pains, expect us to help you move forward.
