The use of coxofemoral prostheses in dogs has been one of the most preferred and efficient methods to treat coxofemoral dysplasia. Complications are frequently diagnosed by radiology and they are due to either material fabrication or host tissue reaction. Bone remodeling, osteoporosis, fractures and aseptic loosening are the common tissue reactions found in patients that have undergone implantation. This study reviews the different radiographic manifestations against coxofemoral implants and the X-Ray evaluation method in the post operatory period of coxofemoral implanted canine patients.
