Purpose: Hemipelvectomy amputation is a surgical procedure in which the lower limb and part of the pelvis are removed.  Although few studies are available on the performance of individuals with hip disarticulation while walking, there is no study on gait analysis of hemipelvectomy subjects. Therefore, this study aimed to evaluate the gait and stability of an individual with hemipelvectomy amputation.
Methods: An individual with hemipelvectomy amputation on the right side participated in this study. He used a Canadian prosthesis with single axis ankle joint, 3R21 knee joint and 7E7 hip joint for more than 10 years. The kinetic and kinematic parameters were collected by a motion analysis system and a Kistler force plate. 
Results: There was a significant difference between knee, hip and ankle motion ranges  and their related time periods on the sound and prosthesis sides. The stability of the subject was better in the anteroposterior direction, than the mediolateral direction. Results revealed a significant asymmetry between the sound and prosthesis sides.
Conclusion: The obtained results suggested a significant asymmetry between the kinetic and kinematic performance of the sound and prosthesis sides, which may be due to lack of muscular power and alignment of prosthesis components.
