“…Adjunctive diagnostic tools are often employed to define this clinical entity. Electromyography has been used to document both typical AIN palsy [6][7][8] and specific isolated denervation of the FPL [9][10][11] but is technically difficult 12 . Ultrasonography has also been utilized to demonstrate decreased muscle bulk, absent active muscle contraction, increased reflectivity, and reduced perfusion on Doppler sonography 13 .…”

Case: Anterior interosseous nerve (AIN) palsy is an uncommon, though well-described, clinical entity. When isolated to the thumb, it can be confused with atraumatic rupture of the flexor pollicis longus (FPL) tendon. A 57-year-old man experienced atraumatic onset of difficulty flexing the distal interphalangeal thumb joint. Magnetic resonance imaging (MRI) demonstrated denervation edema of the FPL, suggesting atypical AIN palsy. Resolution of symptoms and MRI findings occurred concomitantly with nonoperative treatment. Conclusion: Atypical AIN palsy limited to the FPL is a rare clinical entity whose diagnosis can be supported with MRI. Here, we report a successful case of nonoperative management.

"The striated muscles that appeared later on the phylogenetic scale have more white, fast fibers in their composition, more sensitive to metabolic aggression. Based on the composition, phylogeny and anatomical-functional characteristics, we selected the following muscles: semitendinosus, iliac, subscapular, extensor pollicis brevis and flexor pollicis longus. The data from the specialized literature show that the respective muscles are exposed to sports injuries. In principle, one can try to prevent injuries by changing the proportions in types of muscle fibers, possibly through physical exercises, but there is the potential danger of changing joint biomechanics. Keywords: striated muscles, phylogeny, fiber types, sports traumatology."
