Variations appearing in biceps brachii muscle are common with accessory head, different origins, variant insertion, and different pattern of nerve innervation. However, variations appearing in both origin and insertion, and with other anomalous morphology at the same time are seldom. Here we report a complex variational case on the right arm of a 91-year-old Japanese female cadaver. The complex variations included (1) the biceps brachii muscle bifurcated at its distal ending; (2) the long head had its own tendon, which divided into two parts, i.e., a lateral part fused into the fascia between the brachioradialis and extensor carpi brevis, and a medial part attached to the radius about one centimeter ahead of the radial tuberosity; (3) the short head had an accessory origin from the shoulder capsule; (4) the bicipital aponeurosis was of two parts with an anterior superior layer formed by the long head and a posterior deep one formed by the short head; (5) the musculocutaneous nerve was especially underdeveloped that only innervated the coracobrachialis; (6) the existence of communicating branch between the musculocutaneous and median nerves, and the median nerve issued muscular branches to the biceps brachii and brachialis muscles, and (7) the brachioradial muscle had two accessory muscular bundles that originated from the fascia of the brachial muscle (proximal one) and from the bicipital aponeurosis (distal one).

In the present study, four types of variations of the flexor carpi radialis with accessory muscular bundles were classified depending on the origin of the accessory muscular bundle and relationships with the bicipital aponeurosis, biceps brachii, pronator teres, and coracobrachialis. Six types of insertions of the tendon of the flexor carpi radialis were also divided according to their inserted positions on the carpal and metacarpal bones. An accessory muscular bundle of the flexor carpi radialis was found in 4 (1 female and 3 males) of 68 cadavers (5.88%), with five examples in 136 arms (3.68%). It was bilateral in one cadaver and unilateral (two on the right and one on the left) in three. The insertion of the flexor carpi radialis tendon was not only on the proximal surface of the base of the second metacarpal bone but also on the third metacarpal bone, the tubercle of the trapezium, and the scaphoid. These findings and classifications are important in anatomical education, and have important significances in clinical diagnosis and therapies.

Purpose: Although variations of biceps brachii muscle (BBM) and arm arteries are common, however, combined bilateral variations involving muscles and arteries are rarely described. The report's aim was the detailed presentation of a case of bilateral multiple anatomical variations in the upper extremities encountered during the dissection of a 90-year-old Japanese female cadaver. Results: On the left side, a third (accessory) head of the (BBM) was observed. Interestingly, the bicipital aponeurosis was composed of two layers, a superficial layer and a deep one. Arterial variations involved the high division of the brachial artery into the brachioradial artery (BRA), running superficially to the median nerve and the ulno-interosseous trunk occupying a normal position of the typical brachial artery. On the right side, a four-headed BBM was observed. The bicipital aponeurosis was also composed of two layers (superficial and deep), similarly to the left side. On this side, the BRA took origin from the axillary artery and crossed over the median nerve's medial root. Then, the BRA descended along the median nerve. On both sides, the BRA passed between two layers of the bicipital aponeurosis and continued its course in the forearm as the radial artery. Conclusions: Knowledge about the co-existence of multiple variations on the arm is essential for clinicians performing surgical procedures, and for medical education.
