Abstract Rabbits have highly developed hindlimb muscles, whereas their bones are fragile, thus resulting in frequent hindlimb fractures. To repair these fractures, it is important to understand the arterial branching pattern of the femoral artery, as it provides the main blood supply to the hindlimb. Since the descriptions from prior studies are insufficient, the aim of the present study was to determine the detailed arterial branching pattern of the rabbit femoral artery. Therefore, to address this issue, we examined 30 male and 20 female New Zealand White rabbits after colored latex injections into the femoral artery. Results showed that the femoral artery gave rise to the pudendoepigastric trunk, along with the deep femoral, lateral circumflex femoral, superficial caudal epigastric, saphenous, descending genicular, and proximal and middle caudal femoral arteries, in conjunction with frequent individual variations. In all the observed halves, the last branch from the femoral artery was the distal caudal femoral artery. Individual variations in the branching pattern of these arteries occurred independently in the proximal and the distal portions of the femoral artery, and they were, respectively, categorized into four and three major types based on the number of the branching levels along the proximodistal axis of the femoral artery. The individual variations in the arterial branching pattern of the rabbit femoral artery that were demonstrated in the present study may provide an important anatomical basis for refining the orthopedic surgical procedure in the rabbit.

Introduction Rabbits have well-developed hindlimb muscles, whereas their bones are fragile (Meredith 2006; Varga 2014). Therefore, hindlimb fractures frequently occur in rabbits (Sasai et al. 2018). To repair these bone fractures, external skeletal fixation, bone plating, and intramedullary pinning are commonly performed (Mehler 2006; Sasai et al. 2018). To prevent accidental bleeding during the surgical intervention, these techniques need to be performed based on detailed arterial anatomy. However, descriptions of the arterial * Hideshi Shibata [email protected] 1
