A
joint injection (intra-articular injection) is a procedure used in the
treatment of inflammatory joint conditions, such as rheumatoid arthritis,
psoriatic arthritis, gout, tendonitis, bursitis and occasionally
osteoarthritis. A hypodermic needle is injected into the affected joint where
it delivers a dose of any one of many anti-inflammatory agents, the most common
of which are corticosteroids. Hyaluronic acid, because of its high viscosity,
is sometimes used to replace bursa fluids. The technique may be used to also
withdraw excess fluid from the joint.
Diagnostic
ultrasound, also known as Medical sonography (ultrasonography) is an
ultrasound-based diagnostic medical imaging technique used to visualize
muscles, tendons, and many internal organs, to capture their size, structure
and any pathological lesions with real time tomographic images. Our Vienna and
Ashburn area team uses this successfully to help many of our patients
understand the extent of their condition.
Ultrasound
has been used by radiologists and sonographers to image the human body for at
least 50 years and has become one of the most widely used diagnostic tools in
modern medicine. The technology is relatively inexpensive and portable,
especially when compared with other techniques, such as magnetic resonance
imaging (MRI) and computed tomography (CT). As currently applied in the medical
field, properly performed ultrasound poses no known risks to the patient.
Sonography is generally described as a "safe test" because it does
not use mutagenic ionizing radiation, which can pose hazards such as chromosome
breakage and cancer development. However, ultrasonic energy has two potential
physiological effects: it enhances inflammatory response; and it can heat soft
tissue.
Ultrasound
energy produces a mechanical pressure wave through soft tissue. This pressure
wave may cause microscopic bubbles in living tissues and distortion of the cell
membrane, influencing ion fluxes and intracellular activity. When ultrasound
enters the body, it causes molecular friction and heats the tissues slightly.
This effect is typically very minor as normal tissue perfusion dissipates most
of the heat.
