A silver shaded British shorthair cat, 1 year old, female, 3.3kg.

The cat suffering from a lameness of the right hind limb due to a fall down the stairs, was taken to a nearby hospital and found to have a femoral neck fracture, and was subsequently referred to our hospital for hip replacement surgery. A detailed surgical plan was developed for the cat by using BlueSAO iBlueVet, the orthopedic planning software for precise preoperative planning, then, a new artificial joint was replaced with BlueSAOMicro and Nano Replacement System for the cat.The φ10m cup and 2# stem were used during the surgery; three models of φ 6mm (+2) heads were prepared on stand during the surgery.

Preoperative X-ray:

Four preoperative X-ray films were taken, including pelvic AP, pelvic LAT, femoral AP, and femoral LAT.
