The clinical and radiographic findings associated with the presence of hemivertebra ("wedge-shaped"vertebra) in small and brachycephalic breeds of dogs are reported together with the results of post mortem examination in the availabel cases. The condition is characterised clinically by progressive hind-leg weakness, spinal pain, abnormalities of the nervous system and evidence of muscle atrophy or other abnormalities of conformation. Confirmation of the clinical diagnosis is by radiography. It is suggested that the condition is congenital in origin. Breed incidences are reported. The occurrence of the disorder in certain families of dogs suggests also that it may be hereditary. Other congenital abnormalities are seen in some dogs affected by hemivertebrae.
报告了小型和短头犬种中与半椎体（“楔形”椎体）存在相关的临床和影像学表现，以及现有病例的尸检结果。该病症的临床特征为进行性后腿无力、脊柱疼痛、神经系统异常以及肌肉萎缩或其他形态异常的迹象。通过放射照相术可确诊临床诊断。提示该病症起源于先天性。报告了品种发病率。该病症在某些犬类家族中的出现也表明它可能具有遗传性。在一些患有半椎体的犬只中还可见其他先天性异常。
