Nothing Humerus About It!
Nothing Humerus About It!
From New Mexico Wildlife Center
Last weekend, our hospital admitted an American Barn Owl who had been found on the ground with an injured wing. The rescuer, a falconer, correctly identified the injury as a fractured humerus and transported the owl to NMWC for care. When the owl was admitted to our hospital, our team took x-rays, started the owl on medications, cleaned some lacerations on the wing, and wrapped the fractured wing to keep it stabilized until surgery.
As you might be able to tell from the x-ray we took when the owl arrived, the fracture is an oblique one; that is, the break is at an angle, which means a substantial length of bone is affected. During surgery, the bone was stabilized with metal pins as well as dissolvable sutures to hold the angled bone ends together.
The last photo [the one I used as the title image] in this set was taken just a few days after surgery, and as you can see, American Barn Owl 24-750 is alert and appropriately defensive (spreading their wings and lowering their head is part of how this species says "go away") toward humans! The fracture, as well as the lacerations near the fracture site, are beginning to heal. We are hopeful that this very feisty (and very loud!) patient will continue to make good progress toward getting back out into the wild.
This photo was taken toward the end of the procedure, while the owl was still anesthetized (the orange tube is a monitor that goes down the esophagus and the clear tube is delivering oxygen and anesthetic gas into the owl's trachea). The silver bar is an external fixator that holds all of the surgical pins in alignment, and padding is added around the bar and pins to keep the area protected. All of the metal pieces that hold the fractured bone in place are very lightweight - the total weight added is not even half the weight of one of this owl's mouse meals!
Dr. Avery pins the owl's fractured humerus while Wildlife Rehabilitation Manager Stephanie monitors the patient's breathing, heart rate, temperature, and other vital signs. During this procedure, Stephanie was also manually administering breaths to the owl every ten seconds using the inflatable green bag in her left hand.
Well done. Anesthetizing birds is always so tricky

ABO 24-750 is such a boring name.
I’m going to call them BOWser.
I do like that better, but patient #750 for the year is such a nice number. Very factorable!
Yeah 24-750! You go feisty guy!
Props to NMWC!
A hoot salute to them all!
Hoot hoot! 🦉
