Radiographs | Trauma

Pelvic injury

A raptor presents to the wildlife center with a history of trauma. No fractures are palpable. Over the course of one month as the bird is recovering, it becomes evident that the bird is sitting slightly hunched and has developed a slight limp. What could be the problem?

• Answer
Fractures of the pelvic region can be difficult to palpate and often require radiographs. As the fracture heals, the joint if affected, may become limited in range of motion.

 Spinal injury

A fledgling Red-Shouldered Hawk was found on the ground below the nest site.  The hawk could not stand, but had limited deep pain perception in the feet. What might the radiographs reveal?

• Answer:
The arrow reveals the spot where the spinal column is irregular. The vertebrae at this location is elevated dorsally compared to the rest of the spine. This radiograph suggests a fractured back.

Shoulder injury

A raptor with a history of unknown trauma is drooping the right wing. What must be ruled out?

• Answer:
Whole body radiographs are needed to evaluate the shoulder region for any evidence of fractures or dislocations. Note the head of the right humerus is fractured at the shoulder joint as compared to the left side.

Impact Injury

A raptor sustaining impact injury may show what classic signs on radiographs?

• Answer:
Impact injuries to the chest area often result in air visible between the heart and liver.  This is termed pneumocoelom.

Lung injury

A raptor is presented with a history of traumatic or impact injury. Over the next two days the respiratory effort is becoming more labored. What must be ruled out?

• Answer:
Lung contusions.  This type of injury to the lung can be progressive over several days and is considered life threatening.
