Carpal Tunnel Syndrome: Diagnosis by Means of Median Nerve Elasticity—Improved Diagnostic Accuracy of US with Sonoelastography

Abstract

Sonoelastography provides significant improvement in the diagnostic accuracy of the ultrasonographic assessment of CTS.

Carpal tunnel syndrome: elastosonographic strain ratio andcross-sectional area evaluation for the diagnosis and disease severity.

“…Orman et al have published that mean tissue strain was lower in the patients with CTS than in the controls similar to our results [22]. Miyamoto et al concluded that elastography provided significant improvement in the diagnostic accuracy of the ultrasonographic assessment of CTS [23]. Ghajarzadeh et al analyzed 60 median nerves by using the blue and red pixels and their indexes in a three-dimensional matrix.…”

Sonographic cross-sectional area measurement in carpal tunnel syndrome patients: can delta and ratio calculations predict severity compared to nerve conduction studies?

“…Other studies have suggested using the CSA difference between a proximal median nerve measurement at the level of the pronator quadratus and a measurement within the carpal tunnel, resulting in a delta CSA (Δ-CSA). Although these two recently proposed parameters (R-CSA, Δ-CSA) demonstrate better discriminating performance than CSA measurement alone, no correlation was found with NCS severity, and threshold values for NCS grades were not defined [17][18][19].…”

Trapeziohamate Distance in Carpal Tunnel View as a Risk Factor for Carpal Tunnel Syndrome

“…Carpal tunnel syndrome (CTS) is a common median nerve compression neuropathy at the level of wrist (1). It causes numbness and pain in the volar surface of the thumb through the radial half of the ring finger (2).…”

“…Several study have attempted to identify the risk factors of carpal tunnel syndrome (1,3,(6)(7)(8)(9). They identified different personal and medical risk factors of CTS such as age, gender, overweight, arthritis, diabetes mellitus, rheumatoid and thyroid disorders (1,3,(6)(7)(8)(9).…”

“…They identified different personal and medical risk factors of CTS such as age, gender, overweight, arthritis, diabetes mellitus, rheumatoid and thyroid disorders (1,3,(6)(7)(8)(9). They emphasized that middle age (40 -60 years) and female gender are the most significant risk factors of CTS that are not modifiable (3).…”
