In 1813 Gantzer described 2 accessory muscles in the human forearm which bear his name (Wood, 1868; Macalister, 1875; Testut, 1884; Le Double, 1897). The more frequent of the 2 accessory muscles or ‘accessorius ad pollicem’ was found to arise from the coronoid process of the ulna, coursing distally to attach into the flexor pollicis longus muscle (flexor pollicis longus accessory head, FPLah). The less frequently observed or ‘accessorius ad flexorem profundum digitorum’ was again found to arise from the coronoid process and course to join into the flexor digitorum profundus (flexor digitorum profundus accessory head, FDPah). Since their initial description, they have been examined in further detail by a number of authors (Wood, 1868; Macalister, 1875; Le Double, 1897; Dykes & Anson, 1944; Mangini, 1960; Malhotra et al. 1982; Dellon & McKinnon, 1987; Kida, 1988). These studies, most of them focusing on the FPLah, all show different results of prevalence, origin, insertion, relations and nerve supply. We undertook this study with the aim of providing a more accurate account of the detailed morphology of both accessory muscles because of the above-mentioned inconsistent anatomical descriptions and the lack of information as to important aspects such as vascular supply, morphology (shape and length) and the coexistence of both accessory heads.

机译:1813年,Gantzer在人的前臂中描述了2条以他的名字命名的辅助肌肉(Wood,1868年; Macalister,1875年; Testut,1884年; Le Double,1897年)。发现2个辅助肌肉或“ accessorius ad pollicem”中的频率较高,是由于尺骨的冠状突引起的,其远端向远端弯曲,以附着于屈肌弯头长肌(FLEXah longicis副头,FPLah)。再次发现,较少见的或称为“指旁屈肌腱旁突”的原因是冠状突的过程和过程,并合并到指旁屈肌深部(指旁屈肌腱副头FDPah)中。自从最初的描述以来,许多作者对它们进行了更详细的研究(Wood,1868年; Macalister,1875年; Le Double,1897年; Dykes&Anson,1944年; Mangini,1960年; Malhotra等人1982年; Dellon和McKinnon ,1987;纪田,1988)。这些研究大多数集中在FPLah上,都显示出患病率,起源,插入,关系和神经供应的不同结果。我们进行这项研究的目的是,由于上述不一致的解剖学描述以及缺乏有关重要方面(例如血管供应,形态(形状和长度))的信息,因此,我们可以更准确地说明两条辅助肌肉的详细形态。和两个配件头并存。
