Double Pelvic Osteotomy

Double Pelvic Osteotomy (DPO) can be performed in puppies with femoral head subluxation due to increased dorsal acetabular rim slope and or excessive joint laxity. In puppies without signs of osteoarthritis, this technique modifies the direction of the forces inside the joint, redirecting the femoral head inside the acetabulum. During the residual growth period, the femoral head and the acetabulum regain their joint congruity through uniform cartilage loading, thus preventing or limiting osteoarthritis. [1]

The KYON DPO* system integrates the technological features and biological benefits of the Advanced Locking Plate System (ALPS) into the DPO Technique. 

The primary objective of the ALPS system is to reduce the risk of infection. Infection is best prevented by minimizing damage to the vascular supply and maximizing the biological compatibility of implant design, material and production.

The point-contact design of the plate minimizes damage to the periosteum. The shape is pre-contoured to best match the DPO construct, developed through iteration and feedback from Dr. Aldo Vezzoni, DVM, DECVS.

All holes accommodate KYON cortical compression and locking specialty screws. The locking screws feature a novel thread design and locking mechanism. The screw direction is fixed to avoid the osteotomy and maximize construct stability.

KYON DPO plates are manufactured in Switzerland from titanium aluminum niobium (TAN) for supreme biocompatibility and strength, using proprietary processes.
