Femoral Stem Fracture and Successful Reimplantation Using Femoral Window Technique in Canine Cemented Total Hip Replacement: Case Report

Abstract

A fractured stem is a very rare, late complication in total hip replacement procedure in dogs. Here, we present one case after cemented total hip replacement with successful reimplantation, including clinical signs and radiographic findings.

Novel Interlocking Nail Explantation Utilizing Custom-Made Jig and Cortical Bone Windowing Technique in a Dog

“…In much the same way as the approach outlined by Degórska and colleagues, 15 the cortical tibial window technique described in this article relied on the same underling principles. These included no greater than one-third of the tibial circumference being included in the tibial window, so as to not destabilize the tibia; a rectangular window approach over the site of estimated greatest resistance, in this case suspected to be due to the hourglass shape and endosteal callous formation rather than underlying cement; and the application of slanted cortical window edges to prevent excessive collapse upon replacement.…”

“…Since then, the technique has also been applied to the veterinary field, specifically in the removal of cemented total hip stem protheses. 14,15 Degórska and colleagues 15 originally described the windowing technique in a 2-year-old, male Golden Retriever canine that presented for routine 8-week postoperative cemented total hip replacement radiographs. At this point, lateral and ventrodorsal radiographs revealed a prominent midshaft prosthesis stem fracture.…”
