Backgroud: Cobey and Buck described methods to evaluate hindfoot alignment, but it is still unclear which method is better and easier to perform in clinical practice. Purpose: To evaluate the optimal method for radiography of hindfoot alignment. Material and Methods: We randomly selected 50 patients visiting the foot and ankle surgery outpatient department who underwent hindfoot alignment radiography between July 1 and August 31, 2015. Radiographs were taken using both Cobeys and Bucks methods. The patients were divided into three groups by calcaneal inclination angle. We assessed the calcaneotibial angle, calcaneovertical angle and the distance from the bottom of the calcaneus to the mid-tibial axis. A comparative analysis was performed separately using the t-test. Results: One hundred pairs of data for Cobeys and Bucks methods were obtained. The angles were analyzed separately in valgus, normal and varus situations. The results showed no significant difference between Cobeys method and Bucks method regardless of any situation (P>0.05). Regarding the distance between the bottom of the calcaneus and the mid-tibial axis, the average result of Bucks method was about one millimeter larger than that of Cobeys method in valgus and normal cases (P<0.05), except for varus cases (P>0.05). Conclusion: Cobeys and Bucks techniques are the classic and popular hindfoot alignment assessment methods. The use of Bucks technique resulted in a better image with a less technical procedure and less time requirement. It is worthy of being popularized and used routinely for hindfoot radiography.
