The Benefits of Using Ultrasound: Improving Accuracy and Relief

By Jennifer Hopp, MD, CAQSMWentworth Health Partners Seacoast Orthopedics & Sports Medicine

Ultrasound is a form of imaging in real time that is being used more frequently to image and inject variousultrasound.png injuries related to the shoulder, hip, knee and tendons. You may think ultrasound is only used for monitoring a pregnancy, but with advances in technology, ultrasound machines are smaller and have become more readily available to be used in a doctors’ offices. Ultrasound works by using high frequency sound waves to produce real-time, dynamic images of the body right in the clinic. Gel is applied to the skin and a hand-held ultrasound probe is scanned along a body part, producing images of bone, blood vessels, nerves and soft tissue structures such as muscles and tendons. It can be used as part of an exam to better identify injuries and sources of pain. As opposed to an X-ray which only shows bones, ultrasound has no radiation, so risk to the patient is virtually non-existent.

Steroid injections can help reduce inflammation and improve pain. Another useful injection is Platelet Rich Plasma, or PRP for short. PRP is a concentration of platelets from a patient’s own blood and is often used to accelerate healing of tendonitis and improve pain associated with arthritis. Ultrasound is often utilized to improve accuracy of injections to joints, muscles and tendons. Injections can be both diagnostic and therapeutic. “Blind” injections, even in expert hands, are not 100% accurate. Depending on the location, some “blind” injections can be as low as 30-40% accurate. By using ultrasound, a physician can visualize the needle as it enters the skin and traverses to the desired location. Ultrasound guided injections have 90-100% accuracy. They are often less painful to receive as well, due to the ease and speed of locating the correct location compared to “blind” injections.
Another benefit of using ultrasound, is the dynamic, real-time feedback while scanning or injecting the body. With MRI and CT scans, a patient must remain immobile for 5-45 minutes, depending on which body part is being imaged. However, with ultrasound, the joint or muscle can be moved and touched during the imaging process, helping to better pinpoint the diagnosis in real time. At Seacoast Orthopedics and Sports Medicine, our sports medicine physicians are adept at the use of musculoskeletal ultrasound, which is available at all three of our locations (Somersworth, Lee and Pease).
