Ultrasound examination of common flexor attachment. Images (a,b)—a method of applying the probe to obtain both (a)—longitudinal, (b)—transverse sections, (c)—long axis view of a common flexor attachment (precisely above the attachment of the part corresponding to the flexor carpi radialis—FCR); open arrows—superficial, more tendinous portion of the FCR; open arrowheads—deep part of the FCR, with preserved muscular echo structure; white arrows—partially visible anterior part of the medial collateral ligament; ME—medial epicondyle. (d)—Short axis view of the common flexor attachment—open arrows; ME—medial epicondyle; PT—proximal part of the pronator teres muscle (the humeral head). (e)—Scans from strain elastography, (f)—normal CFT in power Doppler mode, (g)—normal CFT assessed with MicroFlow option.
