犬髋关节发育异常的研究进展

犬髋关节发育异常是一种常发于4～10月龄大型品种幼犬，由遗传和其它因素所致的复合性进行性疾病。典型临床特征为疼痛，跛行，主要病理变化为髋臼变浅，股骨头变形，髋关节不同程度的松弛，不完全脱位或全脱位，甚至发展为严重的退行性关节炎。从首次发现本病至今，对本病的遗传特点、诊断方法标准和各种治疗手段都有大量的研究。作者综述了犬髋关节发育异常的发病因素，常用的诊断和防控措施，从而为全面认识本病，并进行深入研究提供参考。

The Research Progress of Canine Hip Dysplasia

Canine hip dysplasia is a complex progressive disease which is caused by genetic and other factors, and it usually occurs in puppies of large-breed dogs whose age is between 4 and 10 months. The typical clinical features are pain and lameness, and the main pathological changes are flattening of the acetabulum, deformation of the femoral head, different degree laxity of the hip joint, incomplete dislocation or total dislocation, and even developed into a serious degenerative arthritis. There are many studies which concern the genetic characteristics, method and standards of diagnosis, various treatments since the disease was first discovered. This paper reviews pathogenic factors, control measures, method commonly used in diagnosis and treatment of canine hip dysplasia, in order to provide references for whole understanding of the disease and further deep research.
