Dr. Tholen, M.D., F.A.C.S., a husband, father, grandfather, and plastic surgeon, never imagined that a zip-lining accident in Mexico would lead to an above-knee amputation. Determined to continue his active lifestyle and surgical career, he sought out expert prosthetic care, ultimately finding the right fit at Hanger Clinic’s Integrated Care Center in Chicago, IL

A Zip Line Adventure That Changed Everything 

Dr. Tholen’s journey as an above-knee amputee began unexpectedly at a friend’s wedding in Mexico. What was meant to be a thrilling zip-lining experience turned into a life-altering event when a braking maneuver caused his leg to become entangled in the zip line. The resulting knee dislocation and ligament damage led to nine surgeries, later resulting in an above-knee amputation. 

Despite the challenges, Dr. Tholen was determined to return to his active lifestyle and career as a plastic surgeon. Just 91 days after his injury, he was back in the operating room. 

Dr. Tholen shared, “I was fortunate to receive high-quality prosthetic care and an above-knee prosthesis from the beginning of my journey, which enabled me to continue working and enjoy an active lifestyle.” 

Seeking the Best Prosthetic Fit 

Initially receiving care in Rochester, Minnesota, Dr. Tholen transitioned to a provider in the Twin Cities, which better allowed him to maintain his prosthetic care and demanding work schedule. However, as his body changed over time, he noticed issues with the fit of his prosthetic socket—particularly the escape valve, which occasionally caught on the edge of the operating table during procedures, loosening the fit of his prosthesis. 

Determined to find a solution, Dr. Tholen connected with Kevin Carroll, Vice President of Lower Extremity Prosthetics at Hanger Clinic, and Leslie Green, Director of Patient Advocacy and Education. They recommended that he visit Ryan Caldwell, L/CP, at the Hanger Clinic Integrated Care Center in Chicago, IL

A Unique Approach to Prosthetic Care 

Dr. Tholen was immediately impressed by the Integrated Care Center’s innovative approach.  

“The facility offers a variety of real-world environments where amputees can test their prostheses, including a golf simulator, weights, kitchen, track, hill, stairs, ramps, and even a rock wall. This setup allowed Ryan to make real-time adjustments to my prosthesis, ensuring my prosthesis functioned optimally in real-world environments before I returned home,” said Dr. Tholen. 

Working with Ryan Caldwell, L/CP, Hannah Moody, MS, and his team, Dr. Tholen received a custom-designed socket tailored to his specific needs, providing optimal comfort and functionality. The new design included a protective shroud over the escape valve, preventing it from catching onto the operating table or steering wheel while driving. Knowing Dr. Tholen’s passion for automobiles, Tony Kapechuk, a technician at the Integrated Care Center, sourced carbon fiber with a metallic red finish to match his red car—an extra detail that made the prosthesis uniquely his. 

“I worked to develop a socket with lowered trimlines that is more comfortable, without sacrificing stability and control. My goal was to provide Dr. Tholen with the most comfortable fitting prosthesis that helped him to continue to work as a plastic surgeon, reach his activity goals, and achieve his greatest quality of life,” said Ryan.

“The team has so much knowledge in their respective specialties, utilizing new research and technology while building off past knowledge and tricks learned along the way. As a plastic surgeon, I respect the time and effort they dedicate to each and every patient to ensure they achieve optimal results. 

I am grateful that Leslie and Kevin referred me to Ryan at the Integrated Care Center, and for the care I received. This has only enhanced my ability to help others in my profession as a plastic surgeon and enabled me to continue an active life outside of work.” 

Whether traveling with his wife Sami, spending time with his six children, golfing, or teaching plastic surgery abroad, Dr. Tholen’s prosthesis supports his passions without limitations.
