Hip dysplasia is a developmental orthopedic joint disease that commonly effects many different dog breeds, which are generally observed bilaterally. Triple pelvic osteotomy (TPO) is one of the most common techniques used to minimize the development of joint subluxation and hip dysplasia in young dogs. However, in the course of time, different ways to reduce the complications of TPO have been described and alternative techniques such as dual pelvic osteotomy (DPO) have been developed. Materials of our study consisted of 12 dogs with hip dysplasia at 7-11 months age range. Six of these dogs were selected from the dogs for 7-9 months old while the other six were selected for dogs at the age of 10-11 months old. In operation, pubic osteotomy was performed initially and then modified DPO plates were placed in ilium following ilium osteotomy. In acute postoperative period, patients were evaluated for ischiadic nerve paralysis symptoms. Preoperative Norberg angle measurements were compared with Norberg angle measurements on ventrodorsal pelvis graphs taken at postoperative 2nd month. As a result, it was observed that DPO was effective in slowing the development of hip dysplasia in the older patient population than 4.5-9 months old. No signs of postoperative ischiadic paralysis or paresis were seen in the patients. No complications such as screw loosening and plate breakage like complications related to the modified DPO plate which we used were encountered.

Kalça displazisi,
genellikle bilateral olarak gözlenen ve birçok farklı köpek ırkını etkileyen
gelişimsel bir ortopedik eklem rahatsızlığıdır. Üçlü pelvik oteotomi (TPO) genç
köpeklerde, eklemdeki sublukzasyonu ve kalça displazisi gelişimini minimize
etmek için kullanılan en yaygın tekniklerden biridir. Ancak zaman içerisinde
TPO’ nun komplikasyonlarını azaltmak için farklı yollar aranmış ve ikili pelvik
osteotomi (DPO) gibi alternatif teknikler geliştirilmiştir. Çalışmamızın
materyalini kalça displazisi tanısı konmuş 7-11 aylık yaş aralığında olan 12
köpek oluşturdu. Bu köpeklerden 6 tanesi 7-9 ay, diğer altısı ise 10-11 aylık
köpeklerden seçildi. Hastalara pubis ostektomisi yapıldı ve ilium osteotomisini
takiben modifiye DPO plakaları iliuma yerleştirildi. Operasyon sonrası, akut
postoperatif dönemde, hastalar ischiadic sinir paralizi açısından değerlendirildi.
Postoperatif 2. ay çekilen ventrodorsal pelvis grafileri üzerinde hesaplanan
Norberg açı ölçümü değerleri ile preoperatif Norberg açı ölçümleri karşılaştırıldı.
Sonuçta 4,5-9 aylıktan büyük hasta popülasyonunda da DPO’ nun kalça
displazisinin gelişimini yavaşlatmada etkin olduğu görüldü. Hastlarda
postoperatif siyatik paraliz ya da parezi bulgularına rastlanmadı. Kullanılan
modifiye DPO plakası ile ilgili vida gevşemesi, plaka kırılması gibi
komplikasyonlarla karşılaşılmadı.
