Eight (male and female) Keeshounds from the ages of one day to eleven months were studied to determine the normal radiographic development of the radius, ulna and carpal bones.
At birth, diaphyses of the radius and ulna are present.
The epiphyses and carpal bones are absent radiographically because they are composed of cartilaginous tissue.
Two weeks later, ossification centers of the accessory carpal bone and lateral humeral condyle can be seen radiographically.
At three weeks of age, the ossification center of the proximal radial epiphysis is barely seen.
At one month, the ossification center of the medial humeral condyle is present.
At six weeks (1 ½ months), the ossification center of the...
