Closed Reduction of Constrained Total Hip Arthroplasty in the ED

A dislocated hip prosthesis is a common occurrence in the Emergency Department. To combat this problem, orthopedists use constraint devices in an attempt to reduce the incidence of dislocation. However, when these devices fail, a more complicated case arises. We discuss a case report in which a patient presented with a dislocation of his hip after implantation of a constrained total hip arthroplasty. We describe a closed reduction procedure using deep sedation, fluoroscopy, and adequate assistance.
