How to treat comminuted fractures of the distal femoral metaphysis in cats?

Today, I would like to share with you how to treat comminuted fractures of the distal femur metaphysis in pet cats.

Accidents often occur, leading to various catastrophic consequences. Sometimes we can treat them, but many times we are powerless. This cat jumped from a high place and suffered a severe comminuted fracture. The difficulty of the surgery is; Young cats are considering the issue of femur growth. Fortunately, at the age of 6 months or older, there is not much residual growth space in the distal femur growth plate. Secondly, there is consideration for the animal's inability to effectively restrict movement after surgery, which involves the movement of the distal femur patellofemoral trochlea and knee joint. The fixed structure used should consider factors such as growth, mechanical stability, and bone healing issues. Based on the above considerations, the distal femur is fixed with dual plates on both the inner and outer sides, which are stable and neutralize the axial compressive force of the bone. PRCL-6.5+5mm Bone Plates are used for internal and external fixation. Adopting the lateral pathway of the knee joint and extending to the mid femur. First, perform medial fixation of the femur, which does not require much shaping of the bone plate on the medial side, and then proceed with lateral fixation. Try to use fewer screws when the structure and mechanics are stable, and use locking screws as much as possible for fixation. After surgery, it is necessary to exercise more to avoid muscle adhesion and quadriceps contraction. Preventive 90-90 bandages can be used to fix for 3-5 days.

The above are preoperative X-rays

Follow up and re examination after surgery are all normal.
