Abstract

ZCTHR offers a reliable alternative for treating dogs with disabling diseases of the hip joints.

Zurich Cementless Total Hip Replacement

“…3,6,10,11 There are no reported contraindications specific to the Zurich THR (Vezzoni A, personal communication, 2016). General contraindications for THR should be considered with the Zurich THR ( Table 1).…”

“…The documentation and management of complications after the Zurich THR have been reported in several large case series and case reports 3,6,10,14,15 ; however, the follow-up and rate of complication differ depending on the published study ( Table 4). Overall complication rate (perioperative and postoperative) for Zurich THR is reported from 16.4% to 26.3%.…”

“…Reported breeds include mixed breed dog, German shepherd dog, golden retriever, Labrador retriever, Newfoundland, Rottweiler, Bernese mountain dog, border collie, pit bull, Belgian shepherd, Doberman, Hovawart, Leonberger, flat-coated retriever, greater Swiss mountain dog, Irish setter, Magyar vizsla, and riesenschnauzer. 3,6,10 Reported patient age at the time of Zurich THR is also varied, with ages ranging from 4.5 months to 12.6 year old. 6 …”

“…Overall complication rate (perioperative and postoperative) for Zurich THR is reported from 16.4% to 26.3%. 3,6,10 Care must be taken when comparing these case series, because several variables are not consistent across all studies. In the case series from Guerrero and Montavon 3 and Vezzoni and colleagues, 6 all cases within each series were operated by a single surgeon with a high level of experience.…”

“…Canine hip dysplasia, traumatic coxofemoral luxation, femoral head and neck fractures, and failed femoral head and neck ostectomy (FHO) are among the most common indications for canine THR. [2][3][4][5][6] Current THR systems can be broadly categorized as cemented, cementless, or hybrid (combination of cemented and cementless implants). Cemented THR systems achieve both short-term and long-term stability with the use of polymethyl methacrylate as the interface between the implant and bone.…”
