A case of THR surgery for femoral head dislocation in a small Shiba Inu

Breed: Shiba Inu, Gender: Male, Weight: 5.6kg, Age: 1 year and 6 months.

Lame after playing with other dogs 3 days ago. The pet owner then took the dog to a nearby hospital and found no significant abnormalities. The dog was brought home and observation revealed that the dog was limping for three consecutive days and had weakness in all four limbs. The pet owner then brought the dog to our hospital for examination. Palpation revealed a sensitive response in the right hind limb, pain in the hip joint, and an inability to extend and abduct. Because of the dog's abnormal sensitivity, the owner decided to sedate the dog and take an X-ray, which revealed a dislocation of the right hind limb. We took into account the fact that the animal was young and active, that it would have a long survival time, and that it would have a good quality of life in the future. After communication with the pet owner, hip replacement surgery (THR) was performed.

We first used BlueSAO iBlueVet orthopedic planning software to give this Shiba Inu an accurate preoperative planning. He was then given a new artificial joint using BlueSAO Cemented Hip Replacement Systemfor small dogs and cats.

The planned implants used were a #2 femoral stem, a 14mm cup, and an 8mm (+0) femoral head with 8mm (+2) and 8mm (+4) femoral head spares.
