Abstract
An Alaskan Malamute (2-year-old, castrated male,
41kg) was referred with bilateral hind limb lameness. The dog had a history of a
bilateral triple pelvic osteotomy (TPO) to correct hip dysplasia one year
previously, a surgery that was unsuccessful. On physical examination, pain and
crepitus were noted in both hip joints. There was hip joint subluxation and mild
degenerative changes bilaterally seen by radiograph. A Zurich cementless total hip replacement
(ZCTHR) was planned for the right hind limb. After a craniolateral approach, an
acetabular cup and a cementless femoral stem were implanted. The femoral head
was placed in the femoral stem, and the prosthetic joint was then reduced. At a
9 month postoperative checkup, there was no pain on palpation or manipulation of
the right pelvic limb, and the range of motion was within normal limits. On
radiological examination, there was no implant loosening. The ZCTHR can thus be
applied in a failed TPO patient as a revision surgery.
