Alterations in hip angles following of juvenile pubic symphysiodesis in ten dogs with hip dysplasia

Bu çalışmanın amacı; kalça displazisi bulunan 3-5 aylık yaştaki 10 köpeğin juvenil pubik simfizyodezis operasyonu sonrasında pre- ve postoperatif klinik ve radyolojik sonuçlarını değerlendirmektir. Pre- ve postoperatif 1, 3 ve 6. aylardaki kalça ekstensiyon testindeki ağrı skorlaması, Ortolani bulguları ve Barden palpasyon testi gibi klinik değerlendirmelerin sonuçları alındı. Standart ventrodorsal pozisyondaki Norberg-Olsson açıları ve distraksiyondaki kalça ekleminin distraksiyon indeksi radyolojik olarak değerlendirildi. Juvenil pubik simfizyodezis, simfizis pubisin büyüme plağı boyunca 2-3 mm aralıklarla (40 W, 12-30 sn), unipolar iğne elektrotlu koter ünitesi yardımıyla uygulandı. Juvenil pubik simfizyodezis prosedürü ile asetabulumun ventrolateral rotasyonu şekillenerek kaput femorisin asetabulum tarafından tam olarak örtülmesi sağlandı. Olgularda kalçanın ekstensiyon testi, Ortolani ve Barden palpasyon testi sonuçları pozitiften negatife dönüştü. Sonuç olarak; juvenil pubik simfizyodezis, kalça displazisi gelişimine predispoze olan veya hastalığın ilk belirtilerini gösteren 3-5 aylık yaştaki büyük ırk yavru köpeklerde kalça displazisine karşı profilaksi ve/veya tedavi sağlamak amacıyla kolay uygulanabilen, güvenli ve başarılı bir prosedür olarak değerlendirildi.

Kalça displazili on köpekte juvenil pubik simfizyodezis operasyonunu takiben kalça eklem açılarında şekillenen değişiklikler

The purpose of this study is to evaluate of pre- and postoperative clinical and radiological outcomes of 3-5 month-old, 10 dogs with hip dysplasia after juvenile pubic symphysiodesis. Pain scoring of hip extension test, Ortolani signs and Bardens palpations were performed pre- and postoperatively, on 1st, 3rd, and 6th months by clinical examinations. Norberg-Olsson angles on standard ventrodorsal on extended radiological views and distraction index on distracted hip radiological views were evaluated by radiological examinations. Juvenile pubic symphysiodesis was applied every 2.0 to 3.0 mm among to the entire length of the growth plate of the pubis via unipolar needle electrocautery (40 W, for 12 to 30 seconds). Acetabular full coverage on the femoral head was provided as a result of ventrolateral rotation of the acetabulum following juvenile pubic symphysiodesis procedure. The hip extension test, Ortolani signs and Bardens palpations were turned from positive to negative. In conclusion, juvenile pubic symphysiodesis is a successful and safe procedure which can be easily applied for prophylaxis and/or treatment of hip dysplasia (HD) in 3-5-month-old, large-breed puppies, which are predisposed to hip dysplasia or showing the initial clinical signs of hip dysplasia.
