Abstract
Building on a paucity of prior reported cases, we report on a patient with an off-label
dual mobility liner, who sustained a dislocation. Following closed reduction in the
emergency room, catching/grinding was felt, and imaging confirmed an intraprosthetic
dislocation (IPD). This required revision hip arthroplasty. Dual mobility dislocations
have the unique risk of conversion to IPDs during closed reduction attempts. There
should be a low threshold to perform closed reductions in the operating room (OR)
setting by an orthopaedic surgeon under full relaxation/sedation to optimize success
and reduce the risk of creating an IPD.
