Tehran University of Medical Sciences Journal of Orthopedic and Spine Trauma 2538-2330 3 1 2017 02 28 71 71 Babak Siavashi Tehran University of Medical Sciences, Joint Reconstruction Research Center, Sina Hospital, Tehran, Iran 2019 07 18 Floating hip refers to concomitant fracture of the acetabulum, pelvis, and femur. We report the cases, our approach, as well as short-term results from 2008 to 2016. There were a total of 11 cases. The most prevalent pelvis fracture type were Tile type C and the most acetabulum fractures were both column fracture. The most femoral side fractures were per-throchantrric fractures (head, neck, intertrochanteric fracture). In most cases, fixation started from the pelvis, acetabulum, and then the femur. There were 5 complications (45%) (1 DVT, 2 nonunion, and 2 AVN). There were 3 cases, which end to THA in the follow up period. It seems this combination of fractures needs special attention. https://jost.tums.ac.ir/index.php/jost/article/view/71 https://jost.tums.ac.ir/index.php/jost/article/download/71/71
