Methodological basis for implantation of a cementless femoral component in canine total hip replacement

Total hip replacement in dogs is an effective method for treating various pathologies of the hip joint. However, the problem of aseptic instability of the femoral component in the postoperative period persists. An analysis of 227 surgeries using the Russian cementless system V@art was conducted. This system was developed based on Swiss KYON technology but incorporates a number of improvements: a monolithic stem made of Ti6Al4V ELI titanium alloy, a double-lead conical thread for the fixation screws, and an optimized protocol for their placement. The results demonstrate that the modified implantation protocol for the V@art system ensures reliable osseointegration as early as 45 days postoperatively, reduces the cost of the intervention, and minimizes risks. The system can be considered a promising alternative to foreign analogues in veterinary practice within the Russian Federation.
