Use of a DeVita Pin to Maintain Reduction of a Dislocated Total Hip Prosthesis in a Dog

SummaryA two-year-old, female spayed Labrador Retriever with bilateral coxofemoral osteoarthritis received an uncemented total hip prosthesis in her left hip. The acetabular component was positioned in a slightly anteverted position. Five weeks after implantation, following a traumatic incident, the prosthetic hip dislocated without disruption of the femoral or the acetabular components. An open reduction of the luxation was performed, followed by a capsulorraphy and placement of a DeVita pin to secure the reduction. The pin migrated cranially to the epaxial musculature and was removed four weeks after its placement. One year after placing the DeVita pin, a followup examination found the animal not to be lame and without any physical or orthopaedic abnormalities.A DeVita pin was used to maintain reduction of a traumatically dislocated uncemented total hip prosthesis, five weeks after implantation.
