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'.
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 ...
Pain relief begins for patients at different times. For some patients it is immediate; for others it may take four weeks. The full effect of the OssaTron procedure may not be realized until the twelfth week following treatment. If relief has not been achieved at this point, a second OssaTron procedure may be recommended by the patient's physician.
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]
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 ...
Achilles tendon degeneration (tendinosis) is typically investigated with either MRI or ultrasound. In both cases, the tendon is thickened, may demonstrate surrounding inflammation by virtue of the presence of paratenonitis, retrocalcaneal or retro-achilles bursitis. Within the tendon, increased blood flow, tendon fibril disorganisation, and ...
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 reflected ultrasound is received by the probe, transformed into an electric impulse as voltage, and sent to the engine for signal processing and conversion to an image on the screen. The depth reached by the ultrasound beam is dependent on the frequency of the probe used. The higher the frequency, the lesser the depth reached. [9]
