·Bristled fox Terrier, nickname: Cola, 5 years old, male, weighing 12.8Kg. The right hind limb did not touch the ground. The course of the disease exceeded two months. The symptoms were relieved after taking painkillers. Palpation of the right femoral muscle shows atrophy compared to the left one. Stretching the hip joint makes it difficult to open the joint accompanied by significant pain. It was diagnosed as avascular necrosis of the femoral head of the right hind limb, and it was decided to perform hip replacement surgery on the right hind limb. Before the operation, precise surgical planning was carried out using the Biolu iBlueVet software. During the operation, the BlueSAOMicro bionic bone cement hip joint system was used for replacement. The implant selection included: 17mm PEEK bone cement acetabular cup, 12mm+2 femoral head, and #3 bone cement femoral shaft. The operation was successfully completed. Hope you recover soon!
