In the spirit of giving this holiday season, and just in
time for the New Year, a group of dedicated veterinary professionals donated
their time and expertise to perform a five-hour surgery on Tocho, an 8-year-old
mountain lion at Cheyenne Mountain Zoo. He is recovering well following the
complex procedure.
Three weeks ago, animal keepers discovered Tocho was having
trouble putting weight on his rear right leg, which was repaired several years
ago after being broken. Our veterinarians visually assessed him and prescribed
medication for inflammation and pain relief. They monitored him throughout the
week, but his lameness did not improve.
Our Zoo's veterinarians called on Colorado State
University’s James L. Voss Veterinary Teaching Hospital and the Colorado
Academy of Veterinary Technology for assistance. Both sets of medical
professionals volunteered to assist with an exam, at no cost to us. On the
morning of December 11, Tocho received a physical exam and x-rays that showed
his prognosis wasn't as good as the team had hoped.
“We initially thought that the cold weather was causing the
stiffness in the previously injured leg and that once the weather warmed up,
Tocho would improve,” Dr. Liza Dadone, Cheyenne Mountain Zoo veterinarian,
said. “Unfortunately, Tocho had a torn cruciate ligament. He needed surgery to
repair it, and he would also need the two bone plates that were previously used
to repair his broken leg replaced.”
“Even during the holidays, Tocho was a priority for all of
us,” Dadone said. “Thirteen medical professionals, seven of whom were doctors,
came together for his surgery.”
Team members donated their time and provided needed medical
equipment and supplies to support the procedure that otherwise would not have
been possible.
As a nonprofit that doesn’t receive any tax funding and
relies on admissions and donations to operate, our Zoo is extremely grateful
for the collaboration with CSU and CAVT.
The groups have collaborated on diagnostic, surgical,
therapeutic and other procedures for a variety of other animals at our Zoo.
“We also work together on writing medical papers to educate
and inform the greater zoo community,” Dadone said. “Our collaborative medical
efforts are not only benefiting animals at Cheyenne Mountain Zoo, but also at
other Association of Zoos and Aquariums institutions.”

We extend sincere thanks to the team that assisted with
Tocho’s surgery - from CSU, Drs. Clara Goh, Matthew Johnston, Ross Palmer, Dana
Ruehlman, two veterinary technicians and one vet-tech student. CAVT’s surgical
team included veterinarian Dr. Dave Rubenstein and a vet-tech student. Cheyenne
Mountain Zoo’s medical team included veterinarians Dr. Liza Dadone and Dr. Eric
Klaphake, hospital manager and vet tech DeeAnn Wilfong, and veterinary
technician Harley Thompson. The two bone plates were donated by DePuy
Synthes.
