| 英文描述 | Spider syndrome is a crippling congenital chondroplasia seen primarily in black faced breeds of sheep. The syndrome consists of humped and twisted spines, limbs that are crooked, relatively fine boned, and disproportionately long and spider-like, a shallow torso dimension from withers to sternum, and a rump angled steeply from tuber sacrale to tuber ischii. In some cases the head appears short and convex when viewed from the lateral aspect, and there may be curvature of the nasal septum. Not all affected lambs have all signs, and lambs that appear normal at birth can develop signs during the first months of life. Ambulation may become difficult as muscle atrophy develops. Clinical pathology is not useful in diagnosis, but radiographs consistently show abnormal endochondral ossification in the elbows, shoulders, and sternum. Inherited as an autosomal recessive. Can be stillbirth and abortion of affected lambs. Pathologic fractures can occur. No treatment is reported. |
