Hip arthroplasty in acetabular and ipsilateral neck femur fracture with central dislocation of femoral head -a rare floating hip injury

A “floating hip” injury is a very rare presentation with an incidence of around 1 in 10,000 fractures. The combination of floating hip with a centrally dislocated femoral head makes the management even more challenging. Conservative treatment has no role except that in unfit patients and surgical treatment has no standard protocol. Literature suggests both internal fixation and arthroplasty as options depending on the acetabular congruity as well as the future chances of avascular necrosis of femoral head. Treatment has to be tailored according to the situation. We encountered one such difficult case which was managed by a combination of both internal fixation and arthroplasty as staged procedure and would like to show our experience which yielded good result and patient satisfaction.
