TENDON AND NERVE SONOGRAPHY
Section snippets
Anatomic Considerations
Tendons form an integral part of the musculotendinous unit, transmitting the tensions generated in muscles to bone.59 The main histologic component of tendons, accounting for approximately 85% of their dry weight, is type I collagen. In tendons, collagen has a complex arrangement, made of highly ordered bundles of fibers grouped to fascicles. Most fibers have a course longitudinal to the tendon axis; some of them, however, may assume transverse and spiral arrangements.20 Collagen bundles are
Anatomic Considerations and Congenital Anomalies
Nerves are round or flattened cords, with a complex internal structure resembling a cable. They are formed of nervous fibers—composed of axons, myelin sheaths, and Schwann cells—grouped in fascicles. The size and number of fascicles included in a nerve depend on individual nerve, distance from site of origin, and amount of pressure the nerve is subjected to. Fascicles are protected and strengthened by a series of connective tissue coverings. Individual fibers are invested by the endoneurium;

2015, Ultrasound in Medicine and BiologyCitation Excerpt :Musculoskeletal ultrasonography (MSU) is a non-invasive, low-cost and frequently used diagnostic technique for detection of pathologic changes of elbow structures (Connell et al. 2009; Croisier et al. 2007; Khoury and Cardinal 2009; Torp-Pedersen et al. 2008; Zeisig et al. 2008). Important pathologic tissue changes associated with clinical symptoms of LET, such as tendon thickening or thinning, calcifications, hypo-echogenicity and tears, can be identified by MSU (Levin et al. 2005; Martinoli et al. 1999, 2002; Walz et al. 2010). Furthermore, the use of MSU plays an important role in the evaluation of tendon changes during and after treatment.
