DOKKYO MEDICAL UNIVERSITY

    It is a pleasure to welcome you to our Department of Orthopaedic Surgery at DMU Nikko Medical Center. I was honored to be named the new Chairman of the Department when Dokkyo Medical University Hospital first opened its DMU Nikko Medical Center in April 2006. Ever since, our physicians and specialists strive to provide comprehensive musculoskeletal care; including the bones, joints, cartilages and nerves, that is of the highest quality to all our patients. We offer advanced treatment for the spectrum of orthopaedic conditions, from ankle sprains, hip, knee, hand or bone cancer surgeries. We also bring together a unique team of physicians, physical therapists and specialists to collaboratively provide the best possible medical care for orthopaedic injuries and illnesses. Our patient-centered care has always been the symbol of our department and I am proud of the members of our faculty and staff who continue that tradition today.

2. Diagnostic Procedures




• MRI is used to examine bones, joints and soft tissues such as cartilage, tendons, and muscles for the presence of structural damage, defects, infection, etc.
• NVC is used to measure how quickly nerves conduct electrical signals through the body, and it is key in diagnosing or ruling out nerve damage or a nerve disorder: e.g. Carpal/Elbow tunnel syndrome
• A bone mineral density test is used mainly to diagnose osteopenia and osteoporosis. It is also used to determine your future fracture risk. The testing procedure typically measures the bone density of the spine and hip.

     We all use our hands, wrists, and forearms throughout the day to perform a variety of activities. If you are suffering from a hand problem, you may be unable to accomplish daily function such as getting dressed, cooking and driving. There are numerous factors that can contribute to discomfort and pain such as an injury, overuse, arthritis or tumors. Hormone imbalance may be trigger to those symptoms. Unfortunately, not many people aware that there comes a time when hand specialists may be necessary to regain functionality of your hand as well as reduce pain. It’s important to see an orthopedic hand surgeon to correctly diagnose and treat the issue before it becomes even worse.

We have a profound understanding of the complex networks of blood vessels, nerves, muscles, ligaments, tendons, and bones that make up the hand and fingers.
