“…It has limited action in carpal flexion; therefore its absence does not lead to loss of function in the forearm or hand and has limited clinical significance. The presence of aberrant structures in the forearm and wrist is known to be an important factor for the development of syndromes of nerve and vessel compression (Georgiev and Jelev, 2007;Slavchev and Georgiev, 2013;Georgiev and Jelev, 2011). The fibro-tendinous band reported herein arched over the ulnar artery and nerve just before they entered the canal of Guyon and the median nerve just before the carpal tunnel.…”

RESUMENVarios músculos y estructuras fibro-tendinosas aberrantes se han identificado en la parte anterior de la muñeca, muchas de las cuales se considera que pueden causar síndromes de compresión neurovascular. A continuación describimos una estructura relacionada con el músculo flexor carpi ulnaris. Durante disecciones de rutina de ambos miembros superiores de cadáveres de adultos fue descubierta una estructura fibro-tendinosa con forma de medialuna en ambos miembros originando de la parte lateral del tendón distal del flexor carpi ulnaris. Esta estructura formaba un arco pasando sobre y cubriendo la arteria y el nervio ulnar antes de que entren en el canal de Guyon, y sobre el nervio mediano justo antes de que entre en el canal carpal. Este arco fibro-tendinoso seguía estrechándose hasta entrelazarse con el ligamento transverso del carpo y las fibras longitudinales de la aponeurosis palmar. En este mismo caso el músculo palmaris longus estaba ausente en ambas manos. Esta conexión entre el arco fibro-tendinoso y el nervio mediano, la arteria y el nervio ulnar en la muñeca posiblemente puede causar compresión neurovascular durante cierta actividad muscular. Palabras clave: músculo flexor carpi ulnaris; variación; significado clínico ABSTRACTVarious aberrant muscles and fibro-tendinous structures have been identified in the anterior wrist, some of them blamed to be possible causes for neurovascular compression syndromes. Herewith, we describe such an intriguing structure related to the flexor carpi ulnaris muscle. During routine dissection of both upper limbs of an adult cadaver, an interesting crescent-shaped fibro-tendinous structure was identified bilaterally, arising broadly from the lateral side of the distal tendon of the flexor carpi ulnaris. This aberrant structure arched over the ulnar artery and nerve before they enter the canal of Guyon and the median nerve just before the carpal tunnel. Further distally, the fibro-tendinous arch narrowed and interlaced with the flexor retinaculum and palmar aponeurosis longitudinal fibres. In this case there was also concomitant bilateral absence of the palmaris longus muscle. Because this aberrant fibro-tendinous arch has very close relations to the median nerve, and ulnar nerve and artery in the wrist, it may possibly cause neurovascular compression during some muscle activity.

“…[2][3][4][5][6][7][8][9][10][11] Numerous variations of this muscle have been described (Table 1). After review of the pertinent literature, the variant FDMBm arising from the flexor carpi radialis tendon presented in this report is a variation not previously reported.…”

“…The reported variations of the FDMBm in the available literature are absence and presence of an accessory slip from the palmaris longus tendon, presence of a slip to the metacarpal, replacement by a tendinous band arising from the flexor carpi ulnaris muscle and inserting into the fifth proximal phalanx and the hamate bone, presence of accessory FDMBm, fusion with ADMm or opponens digiti minimi muscles, origin from the antebrachial fascia, deep abductor-flexor of little finger, FDMBm with triple origin and origin from flexor carpi radialis muscle [25,26,33,[40][41][42][43].…”

The increased number of articles in the last years about hypothenar variations and some misdescriptions and the role of the additional structures to ulnar nerve and artery compression, as well as my unostentatious contribution in the field, provoked me to write this chapter. The aim of it is to present in detail the usual hypothenar muscular anatomy, including the origins and insertions of the hypothenar muscles, their relations to each other, the vascular supply and innervation, the function of the muscles, the reported variations and their possible clinical implications. Herein, I also presented briefly the Guyon's canal anatomy and some interesting comments about it. Presenting the compendium about hypothenar muscles and the canal to my opinion will help the anatomists and the clinicians to better understand the clinically oriented anatomy. They also will be more qualified in the anatomical dissection course as well as during the surgical interventions. The detailed knowledge of the anatomy in the region would be also useful to medical students in better understanding the hypothenar region.
