| SIGNALMENT:
5-1/2 year old Male Turkish Van Cat
HISTORY:
Hit by a car six days prior to presentation. Multiple pelvic fractures
diagnosed by the referring veterinarian. Evaluated for internal injuries,
including pulmonary contusions, diaphragmatic hernia, and bladder integrity.
Stabilization was recommended prior to referral for repair of pelvic fractures.
DIAGNOSIS:
Multiple pelvic fractures (Figure 1) noted on radiographs. The
primary fracture of surgical significance is the right sacroiliac fracture/luxation.
A left ischial fracture and pubic fractures are also present. |

fracture/luxation using a single 2.0 mm screw and 0.045" K-wire. |
TREATMENT:
A dorsal approach to the right sacroiliac joint was made and this fracture
reduced and stabilized using an AO 2.0 mm bone screw placed in lag fashion
across the sacroiliac joint. A single K-wire is added for rotational stability
(Figure 2).
DISCUSSION:
As a general rule, pelvic fractures which should be surgically stabilized
are located at the level of the coxofemoral joints and cranial. This represents
the weight-
bearing section of the pelvis and an earlier return to function can
be expected along with restoration of the normal "box" configuration of
the pelvis.
