title: Spinal mobility in the dog. A study in chondrodystrophoid and non--chondrodystrophoid animals.
abstract: Spinal mobility in chondrodystrophoid and nonchondrodystrophoid animal has been studied radiographically. Movement at the lumbo-sacral articulation is approximately three times greater than at other levels in the lumbar spine. The L7-L6 articulation is the second most mobile level. Movement at other lumbar segments is approximately equal. The range of motion is closely similar for both skeletal types which suggests that this factor alone is not of crucial importance in the aetiology of intervertebral disc disorder in chondrodystrophoid animals.
