Ultrasound-guided hip joint injection is a joint injection in the hip, assisted by medical ultrasound. Hip and groin pain often presents a diagnostic and therapeutic challenge. The differential diagnosis is extensive, comprising intra-articular and extra-articular pathology and referred pain from lumbar spine, knee and elsewhere in the pelvis.
Hip dysplasia can be diagnosed by ultrasound [44] and projectional radiography ("X-ray"). [45] Ultrasound imaging is generally preferred at up to 4 months due to limited ossification of the femoral head up until then, and is the most accurate method for imaging of the hip during the first few months after birth. However, in most instances ...
The Kocher criteria are a tool useful in the differentiation of septic arthritis from transient synovitis in the child with a painful hip. [1] They are named for Mininder S. Kocher, an orthopaedic surgeon at Boston Children's Hospital and Professor of Orthopaedic Surgery at Harvard Medical School.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
There is a limited range of motion of the hip joint. Nevertheless, children with transient synovitis of the hip can usually weight bear. This is an important clinical differentiating sign from septic arthritis. [8] Blood tests may show mild inflammation. An ultrasound scan of the hip joint can show a fluid collection .
The condition is most commonly found in children between the ages of 4 and 10. Common symptoms include pain in the hip, knee, or ankle (since hip pathology can cause pain to be felt in a normal knee or ankle), or in the groin; this pain is exacerbated by hip or leg movement, especially internal hip rotation (with the knee flexed 90°, twisting the lower leg away from the center of the body).
The best known standards and protocols used by DICOM are: [29] DICOM Makes use of the OSI network model. It uses the 2 network protocols on which the Internet is based and which allow data transfer, TCP / IP, and the HTTP hypertext transfer protocol. Additionally DICOM has its own MIME content type. DICOM uses other protocols such as DHCP, SAML ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
