Dj. Deyoung et al., RADIOGRAPHIC ASSESSMENT OF A CANINE UNCEMENTED POROUS-COATED ANATOMICTOTAL HIP-PROSTHESIS, Veterinary surgery, 22(6), 1993, pp. 473-481
Thirty uncemented porous-coated anatomic total hip prostheses in 24 do
gs were evaluated radiographically at 6 months, 12 months, or 18 month
s after arthroplasty. All dogs were fully weight bearing and free of l
ameness at the time of follow-up. Radiographs were assessed for prosth
etic component alignment, percentage of femoral canal fill, resorptive
and formative bony changes, and changes at the implant bone interface
. No evidence of infection, loosening, or failure of component fixatio
n was seen. Settling of the acetabular component and subsidence of the
femoral stem was seen early after surgery. Cortical atrophy was seen
in all femurs and was the most significant bony remodeling change. Ear
ly results of clinical and radiographic evaluation of uncemented total
hip arthroplasty in dogs have been encouraging.
