The respiratory system had to function efficiently under anesthesia.
Body temperature had to be maintained because birds can lose heat rapidly during prolonged procedures.
Heart rate, breathing, oxygenation, and other physiologic parameters were monitored continuously.
The eagle was then positioned so the surgical team could reach the injured vertebral region while minimizing additional movement around the spinal cord.
The Surgeons Exposed the Injured Region Carefully
Once the operative site was prepared, the surgeons approached the damaged area layer by layer.
The goal was not to create a large surgical exposure but to gain enough access to identify the abnormal vertebral relationship and restore stability.
The tissues around the spine were handled conservatively.
Any manipulation near the spinal cord had to be controlled.
An uncontrolled movement of a damaged vertebra could worsen neurologic injury.
The surgeons identified the region seen on diagnostic imaging.
The abnormal alignment was confirmed.
The next task was to improve that alignment and keep it stable.
This was the technically demanding part of the procedure.
The spinal column had to be supported without placing excessive pressure on fragile avian bone.
Any fixation had to remain strong enough to tolerate healing and later movement while being small enough to accommodate the anatomy.
The surgeons worked slowly.
The Procedure Was Technically Successful
By the end of surgery, the injured spinal region had been stabilized to the extent the team believed possible.
Alignment was improved.
The fixation remained secure.
There had been no catastrophic anesthetic event.
Those were important successes.
However, no one knew whether the operation had changed the most important outcome.
The eagle still had to wake up.
Then the neurologic system had to reveal how much function remained.
The bird was recovered from anesthesia under close observation.
When it became conscious, it was placed back onto thick padded bedding.
No perch was provided.
The legs were still weak.
The eagle could not stand.
That was not unexpected.
Spinal surgery does not create instant neurologic recovery.
The team now entered what may have been the most difficult phase of the case.
Waiting.
The First Postoperative Hours Were About Preventing Secondary Problems
A bird that cannot stand requires intensive nursing care even when the primary surgery is technically successful.
The eagle had to be kept clean and dry.
Its body position had to be changed carefully so that continuous pressure did not damage the skin.
The breastbone, feet, wing edges, and other pressure points were checked repeatedly.
Thick towels and soft bedding helped distribute the bird’s weight.
The enclosure remained quiet.
Pain was controlled.
Food and fluids were managed according to the eagle’s condition.
The surgical site was monitored for swelling, bleeding, or other complications.
The team also continued repeated neurologic examinations.
Sensation remained present.
That was important.
There had been no obvious immediate loss of neurologic response following the procedure.
Now the question was whether motor function would begin to return.
The First Day Did Not Bring Dramatic Improvement
The eagle remained unable to stand through the early postoperative period.
It could lift its head.
It watched staff.
The wings moved normally enough for repositioning.
The feet still responded to stimulation.
However, purposeful use of the legs remained limited.
For anyone watching from outside the hospital, that could have seemed discouraging.
The surgeons had completed an extraordinary procedure, yet the bird still looked almost the same.
The medical team viewed the situation differently.
The goal of surgery had been stabilization.
The nervous system needed time.
Inflammation would not disappear immediately.
Bruised neural tissue could take days or longer to demonstrate whether meaningful recovery was possible.
The absence of instant improvement did not equal failure.
Spinal Trauma Can Change Over Time
After a major spinal injury, the initial neurologic picture may be influenced by more than permanent tissue destruction.
Swelling can compress neural structures.
Inflammation can disrupt signaling.
Small hemorrhages can affect local function.
Pain can limit movement.
Muscles weaken rapidly when they are not used.
As some of those factors change, movement may improve even though the original injury remains serious.
That is why the team continued documenting small neurologic changes rather than waiting only for the bird to suddenly stand.
A stronger toe response mattered.
An increase in muscle tone mattered.
A more purposeful leg movement mattered.
With spinal injury, progress often begins at a scale far smaller than a step.
The First Improvement Was a Small Movement of the Toes
Several days after surgery, staff noticed a subtle change during a routine examination.
When one foot was positioned against the towel, the toes flexed.
The movement was slight.
At first, the team was careful not to overinterpret it.
A reflex can sometimes mimic purposeful movement.
The examination was repeated later.
The toes flexed again.
This time, the response appeared more deliberate.
The opposite foot also began showing slightly stronger movement.
The eagle was not standing.
It was not gripping normally.
But the neurologic picture had changed.
“The first sign of progress was extremely small,” Cusack said. “We were not looking for the bird to walk across the enclosure. We were looking for evidence that motor function was beginning to return at all.”
The small toe movement was exactly that.
The Team Still Refused to Predict the Final Outcome
Encouraging neurologic signs can create pressure to declare a recovery.
The veterinary team resisted that.
A single movement could not tell them whether the eagle would eventually perch.
It could not tell them whether both legs would regain equal strength.
It could not predict landing ability.
It certainly could not confirm that the bird would ever be releasable.
“With spinal injuries, we have to be very careful about what we promise,” Cusack said. “Movement is good. Preserved sensation is good. But the question is whether those findings will eventually become useful function.”
Useful function was the standard.
Not movement for its own sake.
The Next Goal Was Weight-Bearing
As the feet became more active, the rehabilitation team began considering controlled supported standing.
This was introduced cautiously.
The eagle’s body was stabilized while the feet were positioned beneath it.
The goal was to allow the legs to accept a small amount of weight without permitting the bird to collapse or twist the healing spinal region.
The first sessions lasted only a short time.
The legs trembled.
The eagle leaned heavily into support.
Then it was returned to the padded floor.
These brief sessions were not designed to exercise the bird aggressively.
They were designed to reintroduce a function the nervous system had temporarily lost.
Muscle Loss Became Another Concern
An eagle does not need many days of inactivity before muscle condition begins to decline.
A bird unable to stand also risks stiffness in the joints and loss of flexibility.
The rehabilitation team therefore used gentle physical therapy when medically appropriate.
Passive range-of-motion exercises helped maintain joint movement.
The feet and toes were positioned naturally.
The legs were supported through limited controlled motion.
None of the exercises was allowed to produce excessive stress at the surgical site.
The team was trying to preserve the body the neurologic system would need if recovery continued.
There would be little benefit in restoring neural signals to legs that had become too stiff or weak to use.
The Eagle Began Pushing Against the Floor
The next meaningful improvement came when the bird started pushing its body upward.
At first, the movement was small.
