Plantar calcaneal bursitis is a medical condition in which there is inflammation of the plantar calcaneal [1] bursa, a spongy fluid filled sac that cushions the fascia of the heel and the calcaneus (heel bone). It is characterized by swelling and tenderness of the central plantar heel area. It is sometimes called 'Policeman's heel'.
Middle age is the most common age of affection, females are more affected than males, and the occurrence is often bilateral. A clinical feature of this condition is pain in the back of the heel, which is more after rest. Clinical evaluation and lateral radiographs of the ankle are mostly enough to make a diagnosis of Haglund's syndrome. [2]
The ultrasound equipment must be sufficiently high-quality to give a correct image-processing result, which can then provide invaluable information, mainly at the superficial level. It must be able to provide both color and Doppler imaging, technologies that developed alongside the development of ultrasound. Doppler measurements which trace the ...
An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. [6] In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. [13]
A calcaneal spur (also known as a heel spur) is a bony outgrowth from the calcaneal tuberosity (heel bone). [1] Calcaneal spurs are typically detected by x-ray examination. [2] It is a form of exostosis. When a foot is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. Generally, this has no effect on a person ...
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.
Retrocalcaneal bursitis is an inflammation of the bursa located between the calcaneus and the anterior surface of the Achilles tendon. [1] It commonly occurs in association with rheumatoid arthritis, spondyloarthropathies, gout, and trauma. [2] The pain is usually on the back of the heel and swelling appears on lateral or medial side of the tendon.
The transducer is typically separated from the test object by a couplant [4] such as a gel, oil or water, [1] as in immersion testing. However, when ultrasonic testing is conducted with an Electromagnetic Acoustic Transducer (EMAT) the use of couplant is not required. There are two methods of receiving the ultrasound waveform: reflection and ...
