Plain-English summary
An 8-year-old male English Setter had a dislocated hip joint after receiving a total hip replacement four months earlier. The dislocation was caused by a fracture in the plastic liner of the hip implant. The veterinarian performed revision surgery to replace the broken liner, successfully putting the hip back in place. This case highlights a rare issue with this type of hip replacement in dogs, which had not been reported before. After the surgery, the dog was able to recover and regain normal function.

Abstract
An eight-year-old male English Setter was referred for management of a dislocation of a cemented dual mobility canine total hip prosthesis that occurred four months after the initial surgery. Revision surgery showed that the dislocation was associated with fracture of the ultra-high molecular weight polyethylene liner. The dislocation was successfully reduced after replacing the liner. A dual mobility acetabular component is composed of a mobile polyethylene liner inside a metallic cemented cup. Chronic wear of the components of a canine dual mobility total hip replacement has not been described previously. The use of this type of implant is fairly recent and limited long term follow-up of the implanted cases may be the explanation. Acute rupture of a polyethylene liner has never been described in humans, the only case of rupture of a polyethylene liner occurred 10 years after implantation. The case presented here of rupture of the polyethylene liner of a dual mobility total hip replacement is a hitherto unreported failure mode in this model of acetabular cup in the dog.
