Figure 3.2.2 Occipitoatlantal Luxation (Canine) CT
1y FS Keeshond cross with acute cervical injury
after being struck by an automobile earlier in
the day. A CT examination was performed with
the dog on a backboard in lateral recumbency.
Images a–c were acquired at the level of the
occipitoatlantal joint and are ordered from
cranial to caudal. The right occipital condyle
(a–d: arrow) is axially subluxated in relation to
the cranial articular fovea of C1 (a–c: asterisk).
The left occipital condyle is ventrally luxated
(c,d: arrowhead). Closed reduction of the luxa-
tion was successfully performed using fluoro-
scopic guidance.
