Materials and Methods: Twelve dogs with hip problems (dysplasia, luxations and fractures) were used. Equipment, Ortho-Pet, Izmir (Turkey) were manufactured. It was approached with craniolateral incision of craniodorsal sides of the hip trochanter major level. Caput femoris excision was performed by osteotomy. And then, acetabulum was enlarged. After acetabular cup have placed and it was fixed with screws. Then the implants was placed for collum femoris. Implant head of the neck portion was steeled and the hip joint was in place. In controls, inspection, palpation and radiographic examination was performed for post-op 15 days and 1, 3 and 6 months.

Results: Seven dogs (58.3%) in the postoperative prognosis is seen good or very good condition. Clinical examination of patients with a good prognosis in 15th and 30th days showed similarities between each other. Comparison of post-operative 90th days with 15th and 30th day prognosis show that the gait problems was eliminated and to considered to be very good condition. It was also observed that the extremities used as intended. The extremities were not used very well and lameness of varying degrees in 5 dogs (41.6%). Radiograhic examination of these dogs were showed loosening of the collum femoris apparatus, subluxation and the acetabular components may not fixed into the acetabulum properly.

Conclusion: Although the first impression of cementless PTKP's was shown some technical problems, it has been concluded that it is economic, development devices and encouraging of the first results. In addition, monitoring of longer-term outcomes PTKP's more than 6 months is thought to provide important information for the availability and development.
