In recent years, joint disease and fracture repair in small animal orthopedic area is dramatically advanced due to newly developed implant for small animals. However, there is no implant can be fixed from toy size to large dogs. Especially, it is very difficult to choose the adequate implant for the radioulnar oblique fracture at the distal end in toy dogs less than 1 kilogram in body weight. Also, pelvic fractures occurred frequently in toy dog, it has continuous curved surface in narrow range, so that special plate is necessary to achieve a satisfactory fracture repair. Several chronic cases including traumatic dislocation, intra-articular fracture and pelvic fracture cannot be satisfactory repaired because of disturbance by strong muscle contractor. Even now at almost anything available, development of a dedicated small animal medical instrument and implant are far behind compared to the situation in human medicine. So we devised and applied a new surgical procedure with dedicated repairing instrument and implant for the case which struggled to repair in the past. As a result, we obtained great advantages including simplified surgical operation, significant reduction of an operation time, obtained reliable fixation, reduction in complications, and so on.

Most of them which will be presented in this lecture are still in the process of development, but we obtained good clinical results. Our daily orthopedic treatment in the clinic, bandaging, implants, instruments, including surgical procedures are still immature. So we have realized that we should modify and complete each one carefully every day.
