Outcome and complications after dual mobility total hip replacement

“…No aseptic loosening of the femoral implant was observed in our study. In a previous series of 125 consecutive cases bearing the same femoral implant in combination with a standard polyethylene cemented acetabular component, and with a mean follow-up time period of 31 months, only two cases of aseptic loosening of the femoral implant were observed (20). The design of the femoral implant may play a role in that low rate of aseptic loosening of the femoral implant.…”

“…Fifty dogs eventually met the inclusion criteria. The first 16 of those dogs had been included in a formerly published paper reporting preliminary results after dual mobility hip prosthesis implantation (20).…”

“…With no cases of postoperative dislocation, our short-term results concerning postoperative hip stability with the dual mobility hip implant are excellent. Conversely, dislocation was the most frequent complication for a previous generation hip prosthesis, which used the same modular femoral head and stem design (5.8% of 125 cases, representing 50% of all complications) (20). The results of our study also favourably compare with most results published for other canine hip prostheses, with postoperative dislocation rates ranging from one percent to 14%, and dislocation almost always being the most common postoperative complication (2-4, 7, 8, 22-34).…”

“…A dual mobility cemented acetabular component a has been designed for use in dogs in association with a previously described modular femoral component (19,20). Preliminary results after implantation in the first 24 canine cases of the combination of the dual mobility acetabular component and this femoral component have been reported based on a telephonic survey of owners with three months minimal follow-up (20). In that early study, there were not any complications reported.…”

Dual mobility canine total hip prosthesis: Implant characteristics and surgical procedure

“…A dual mobility cemented acetabular component has been designed for use in dogs. This acetabular component has been used by the authors since 2007 in association with a previously designed modular femoral component (5). The purpose of this report is to describe the implant characteristics, the procedure for implantation, and to comment on some expected biomechanical properties of this original implant combination, with reference to the most relevant and recent veterinary and human surgical literature.…”
