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.
1813年，甘策描述了人类前臂中的两块副肌，这两块肌肉以他的名字命名（伍德，1868年；麦卡利斯特，1875年；泰斯特，1884年；勒杜布勒，1897年）。这两块副肌中较常见的一块，即“拇收肌副肌”，被发现起于尺骨冠突，向远端走行并附着于拇长屈肌（拇长屈肌副头，FPLah）。较少见的那块副肌，即“指深屈肌副肌”，同样起于尺骨冠突，走行后汇入指深屈肌（指深屈肌副头，FDPah）。自首次描述以来，已有多位作者对它们进行了更详细的研究（伍德，1868年；麦卡利斯特，1875年；勒杜布勒，1897年；戴克斯和安森，1944年；曼吉尼，1960年；马尔霍特拉等人，1982年；德伦和麦金农，1987年；木田，1988年）。这些研究大多聚焦于拇长屈肌副头，所有研究在发生率、起源、止点、关系和神经支配方面均显示出不同的结果。由于上述解剖描述不一致，且缺乏关于血管供应、形态（形状和长度）以及两个副头共存等重要方面的信息，我们开展了这项研究，旨在更准确地描述这两块副肌的详细形态。
