A Golden Retriever, 9 months old, 31Kg. The dog's femoral head was dislocated due to hip dysplasia. The dog had bilateral hip dysplasia. After preoperative evaluation, it was decided to perform THR surgery on the more severely dislocated side first.

The pet owner conducted a comprehensive understanding and comparison before the surgery, and ultimately chose to have the dog's surgery at our hospital. Choose the domestic biological hip replacement system from BlueSAO. According to the preoperative planning, choose 26mm biological cup, 7# biological femoral stem, 16mm femoral head (intraoperative test +6mm), and 18mm lateral bolt.

Preoperative X-rays:

Before surgery, x-rays were taken after the animals were sedated. Properly taking X-rays is conducive to making detailed preoperative planning.

X-rays were taken in the following four positions: anteroposterior pelvis, lateral pelvis, anteroposterior femur, and lateral femur. Before surgery, select the appropriate acetabular cup according to the anteroposterior and lateral X-rays of the pelvis, and select the appropriate femoral stem based on the anteroposterior and lateral X-rays of the femur. Note; rulers should be added during X-ray taking.
