چکیده

زمینه مطالعه: دیسپلازی مفصل لگنی‌رانی یک بیماری توارثی غیر‌مادرزادی می‌باشد که مخصوصا در نژادهای بزرگ جثه رخ می‌دهد. تعداد زیادی از سگ‌های درگیر، نشانه‌ی بالینی خاصی را نشان نمی‌دهند و این بیماری به تدریج سبب ناتوان شدن و ضعیف شدن سگ‌ها می‌شود.
هدف: بررسی مقدماتی رخداد این بیماری براساس معاینه بالینی و رادیولوژی در سگ‌های نژاد بزرگ ارجاعی.
روش کار: تعداد 36 قلاده سگ نژاد بزرگ بعد از انجام معاینات بالینی و تست ارتلانی، با استفاده از حالت گماری پشتی شکمی با پاهای کشیده جهت بیماری دیسپلازی مفصل لگنی‌رانی مورد ارزیابی قرار گرفته و با استفاده از سیستم درجه‌بندی FCI به 5 درجه A، B، C، D و E طبقه‌بندی شدند. همچنین روش PennHIP جهت اندازه‌گیری DI اجرا شد.
نتایج: دیسپلازی مفصل لگنی‌رانی در2/72% سگ‌ها تشخیص داده شد که 1/11% بصورت یکطرفه و 1/61% دوطرفه درگیر بودند. 73% موارد درگیر از جنس نر بودند. از 14 قلاده سگ دارای علامت بالینی، دیسپلازی مفصل لگنی رانی در 11 قلاده مثبت گزارش شد و در 22 قلاده سگ فاقد علائم بالینی، 15 قلاده واجد دیسپلازی مفصل لگنی رانی بودند. تست ارتلانی در 33 مورد منفی کاذب و در 6 مورد مثبت کاذب نشان داد.
نتیجه‌گیری نهایی: با توجه به رخداد نسبتا بالای این عارضه، ارزیابی رادیولوژی مفصل لگنی‌رانی در نژادهای مستعد به منظور تشخیص و برنامه‌های غربالگری دیسپلازی مفصل لگنی‌رانی ضروری می‌باشد و نباید فقط بر اساس معاینات بالینی و تست ارتلانی در مورد وضعیت مفصل اظهار نظر کرد.

چکیده [English]

Background: Hip dysplasia (HD) is an inherited, non-congenital disease that is particularly prevalent in large and giant breeds of dogs. The vast majority of dogs afflicted with HD show no clinical signs and it can be a highly debilitating condition for dogs.
Objective: Aim of this study is a preliminary study on hip dysplasia based on clinical and radiographical examination in referral large breed dogs referred to veterinary teaching hospital of Ferdowsi University of Mashhad.
Methods: Thirty six large breed dogs were examined for HD using Standard ventrodorsal hip extended view, and graded into five categories (A, B, C, D and E) using the FCI scoring system. PennHIP method was performed for measuring Distraction Index (DI). The Ortolani method was done to evaluate hip joint laxity.
Results: HD was found in 72.2% of the dog, which included 11.1% unilateral and 61.1% bilateral.
73% of the afflicting cases were male. HD was reported In 11 dogs among 14 dogs with clinical signs and among 22 dogs without clinical signs 15 dogs were affected by HD. Ortolani test represented false negative in 33 cases and false positive in 6 cases.
Conclusion: This study revealed the radiological evaluation of hip joint is essential in susceptible breeds for diagnosis and screening program of HD
