Plain-English summary
A 4.7-year-old neutered male Lagotto Romagnolo was brought in because he couldn't put weight on his left back leg. X-rays showed that his hip had dislocated and there was a fracture in his thigh bone. A mass that looked like an inflammatory granuloma (a type of tissue growth) was found, so the vet performed surgery to remove it, fix the fracture, and replace a loose part of the hip implant. After three months, the dog was using his leg normally again, and three years later, he showed no signs of further issues with his hip.

Abstract
A hip luxation 3 years following a cementless total hip replacement was diagnosed in a 4.7-year-old neutered male Lagotto Romagnolo that presented with a non-weight-bearing left pelvic limb lameness. Orthogonal radiographs revealed a left hip luxation and an osteolytic fracture of the greater trochanter. A mass consistent with an inflammatory granuloma was identified on preoperative computed tomography scan. Surgical revision consisted of granuloma excision, replacement of the loose acetabular cup, and repair of the femoral fracture with a locking plate. Fracture biology was augmented with the use of recombinant human bone morphogenetic protein 2 (rhBMP2) impregnated collagen sponge applied around the acetabulum and femoral fracture site. Osteointegration of the prosthetics and fracture healing were documented within 3 months of revision. Long-term follow-up at 3 years postrevision showed normal limb usage and no further evidence of total hip replacement complication.
