Abstract

Amaç: Bu çalışmada, kalça eklemi problemli köpeklerde, Pamuk’s Total Kalça Protezi (PTKP) sistemi uygulama ve sonuçlarının değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Kalça problemi olan (displazi, çıkık ve kırık) 12 adet köpek değerlendirildi. Kalça protez ekipmanı (Ortho-Pet), İzmir (Türkiye)’de imal edilmiştir. Kalça ekleminin craniodorsal yüzüne trochanter major düzeyinde, craniolateral ensizyonla yaklaşıldı. Caput femoris’in eksizyonundan sonra acetabulum genişletildi. Acetabular komponent yerleştirildikten sonra vidalarla sabitlendi. Daha sonra collum femoris’e femur komponenti yerleştirildi. İmplant başı, implantın boyun kısmının üzerine çakılarak, kalça eklemi yerine yerleştirildi. Operasyondan sonra 15. gün ile 1, 3 ve 6. aylarda inspeksiyon, palpasyon ve radyografik muayeneler yapıldı.Bulgular: Yedi köpekte (%58.3) postoperatif dönemde prognozun iyi ve çok iyi olduğu görüldü. Prognozu iyi olan olguların klinik muayeneleri 15 ve 30. günde birbirlerine benzerlikler gösterirken, post-operatif 90. günde ise post-operatif 15 ve 30. günde yürüyüş problemlerinin ortadan kalktığı ve ekstremitenin istenildiği gibi kullanıldığı tespit edildi. 5 köpekte (%41.6) ise ekstremitenin iyi kullanılamadığı ve çeşitli derecelerde topallıkları olduğu gözlendi. Bu olgularda radyografik muayenelerde collum femoris aparatının gevşemesi, sublukzasyon ve acetabular komponentin acetabulum içine tam sabitlenmediği tespit edildi. Öneri: Sementsiz PTKP’nin ilk sonuçlarında bazı teknik problemler görülmesine rağmen köpeklerde kalça problemlerinde ekonomik,
geliştirilebilecek ve sonuçlarının cesaret verici olması açısından yararlı olduğu ifade edilebileceği kanısına varıldı. Ayrıca, PTKP’nin 6
aydan daha uzun dönem sonuçlarının takip edilmesi kullanılabilirliği ve geliştirilebilirliği açısından önemli bilgiler vereceği düşünülmüştür.

Implementation of cementless Pamuk's Total Hip Replacement (PTKP) in dogs, and first evaluation of the results

Abstract

Aim: In this study, application and results of Pamuk's Total Hip Replacement (PTKP) system was evaluated the dogs with hip problems. 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.
