“…They also reported in one out of 17 cases, fibres of only the short head of the biceps brachii tendon contributing to the aponeurosis. Further, they have stated that the short and long head offer varying contribution not only to the distal tendon of biceps brachii but also to the BA [6]. Athwal et al [1] reported that the BA originated from the distal part of short head of the biceps in all 15 specimens studied; whereas, Eames et al [7] stated major role of long head in the formation of BA.…”

“…Athwal et al [1] reported that the BA originates from the short head of the biceps but have not mentioned any contribution from the long head in the formation of BA. Dirim et al [6] have reported that the BA was formed by superficial tendinous fibres arising from both short and long head. They also reported in one out of 17 cases, fibres of only the short head of the biceps brachii tendon contributing to the aponeurosis.…”

“…There is no unanimity in the reviewed literature, concerning the role of the BA in the actions of the biceps brachii. Eames et al in 2007 [7] have emphasized the role of long head in supination and the short head with BA in flexion, while contrary to this Dirim et al [6] have described the role of the BA in the supination. The aim of the present study was to assess the morphology of BA and to correlate its role in the actions of biceps brachii.…”

The bicipital aponeurosis (BA) is the distal aponeurosis of the biceps brachii which usually covers the median nerve (MN), and the brachial artery (BrA) and sometimes causes compression of these structures. Since these situations are rarely reported in the literature, BA frequently does not come to mind as a cause of such compression.Therefore, the diagnosis may be delayed. In this study, we aimed to investigate the morphometry of BA and its relationship with the surrounding neurovascular structures and to draw attention to BA as a structure that can cause entrapment of the MN and rarely, the BrA. We examined the MRIs of the elbow of 279 patients (107 women, 172 men) aged between 18 and 72 years. We measured the thickness, length and width of BA, and investigated the anatomical relationship between BA, BrA, and MN. The respective median thickness, width, and length of BA were 0.7 (0.4-1.8 mm), 18.0 (6.0-34.0 mm), and 32.0 (18.0-50.0 mm), respectively. In all sections examined, the BA covered the BrA and MN, and was located immediately anterior to the BrA. In 225 (80.6%) of 279 MRIs, the BrA was located anterior to the MN and posterior to the BA. In the remaining 54 (19.4%) MRIs, the MN was located anterior to the BrA and posterior to the BA. The respective median thickness, width, and length of the BA were 0.7 mm, 18.0 mm, and 32.0 mm, respectively. It covered the BrA and MN and was located immediately anterior to the BrA. The BA sometimes causes compression syndromes of these structures, therefore, for physicians, it is important to understand the anatomy of the BA.
