As both Director of the Minimally Invasive Orthopedic Institute and Grant Medical Center in Columbus, Ohio, and Adjunct Professor of Biomechanical Engineering at the University of Tennessee, Dr. Ray Wasielewski is well positioned to understand how the lab translates to the OR.
Prior to being concerned about bones and loads cells, however, he spent his early years thinking about engineering. “I was born in Schenectady, New York, and was one of six children. I was an active child who did a lot of sports and outdoor recreation. Much of our time was spent hunting and fishing in the Adirondacks far away from civilization. My father was an engineer who worked on jet aircraft engines and gas turbines and taught metallurgy at Rensselaer Polytechnic Institute. My mother worked at keeping six kids fed and only later took time to return to school and get a degree in art. She is now a member of the exclusive Cincinnati Art Society. Having the chance to observe my father’s love of engineering stimulated me to follow in his footsteps.”
But life experience and a career test would point Ray Wasielewski in another direction. “I entered Virginia Polytechnic Institute and State University as an undergraduate in 1977 and stayed on to obtain a master’s of science in materials engineering. During this time my interest in research was peaked, so I went to Oak Ridge, Tennessee, for a summer to work on novel materials. It wasn’t very fulfilling, however, as there were governmental issues that slowed things down. The following summer I interned at General Electric and found out the meaning of ‘messy business.’ One day there had been a union problem and I was assigned to keep an eye on things overnight. We found out the next day that during the night the turbine blades had been damaged on purpose. It made me realize I didn’t like the business of engineering, in particular how the separation between management and union makes it difficult to get along. I returned to school in the fall and took a career test to determine my standout interests and talents. According to the test, right after engineering was medicine. I spent two months volunteering at the ER in Blacksburg, where the doctors let me stitch people up and help in other ways. While GE already had a position for me in their young executives program, I turned it down. When I told my dad there was silence on the other end of the phone line. He eventually got used to the idea, however. I had missed the normal cycle for entry into medical school, so I delved into premed courses and got my master’s in metallurgy, something that would prove valuable for my later work.”
His initiation into the world of medicine would require a mental shift. States Dr. Wasielewski, “I entered medical school at Ohio State in 1982. The first two years were pretty hard because the exams were multiple choice. I was accustomed to graduate engineering school where we had a three-hour open book test with three questions that were all about applying fundamental principles to complex problems. I soon found out that medical school was largely about regurgitating facts. Once I got to clinics and started applying knowledge to problems, however, I did well. I knew I just had to get through and gain that foundation. This was particularly challenging, though, because I hadn’t taken many of the prerequisites. One case during this time affected my career significantly. We had a patient with a fistula in his bowel that required resection. We had taken blood gasses, so after the surgery I plotted out the blood gases and showed that we had missed a spot; the bleeding continued and I alerted the Chief Resident. That was my introduction into the importance of attention to detail. The Chair of the department learned of my work in the case and arranged for me to go to the Pittsburg Presbyterian Hospital for orthopedic residency.”
Dr. Wasielewski would move through the next five years without taking a deep breath. “I began my residency in 1986, an experience that was more rigorous than I expected. For four years I took no vacation and had call mostly every other night. My wife survived by riding horses and working as a pharmacist. We were actually apart for a while, as she stayed in Ohio while our home was being built. I was busy working with wonderful orthopedists like Dr. Harry Rubash, who is now the Chair of Orthopedics at Harvard. An extremely detail-orientated surgeon, he had trained under Bill Harris at Harvard and brought those skills back to Pitt. He taught me to have 100% of my mind focused on the moment, and to get engrossed to the point that I did not even hear things around me. Because of him I learned not to talk when I operate; I just put my hand out for instruments. We wrote manuscripts together and he persuaded me to become an academic orthopedist.”
Other mentors would contribute to Ray Wasielewski’s intellectual development, as well as to his growth as a calm surgeon. “I began my fellowship at Rush-Presbyterian St. Luke’s Medical Center in 1991. I was under the direct tutelage of Dr. Jorge Galante, the inventor of porous coating. Working with the tremendously intellectual Dr. Galante, who thought like a metallurgist, reawakened a desire in me to use my engineering skills in orthopedics. I had always known I would study wear, but now I started to try on an inventor’s hat. Another remarkable person at Rush was master surgeon Dr. Aaron Rosenberg, who I witnessed handle the worst cases with exceptional skill. He would know exactly how long he could be in the case next door before he would move to help me in my room, meaning, of course, that he could readily judge our abilities and knew how much supervision we needed. He also taught me a lot about keeping things in their proper perspective. I remember one night I got a call from the hospital saying that there was a problem clearing a patient for surgery. I worked from 3 a.m. – 6 a.m. to get the patient cleared when Aaron came in the door and could see that I was upset. I told him, ‘I don’t think the patient is cleared,’ to which he replied, ‘Well, if the case is cancelled that is just nature’s way of telling us that we need to go out to lunch this afternoon. How about dim sum!’ After I recovered from the shock I could see this was his way of telling me, ‘Let’s step back a little. Don’t sweat the little stuff.’ Again, a few months after the fellowship I called Aaron because I had a complication where I couldn’t cure a knee infection and was despondent. He said, ‘Is the patient still alive?’ ‘Yes,’ I responded. He then said, ‘Then it’s still just an infected knee. Call me anytime you have a real complication.’ While we doctors want to care about everything we do, it can also be a burden if we are overcome by failure. It would be crippling. I remain forever indebted to Aaron for the invaluable lessons he taught me. They have provided significant guidance to my life as a surgeon and caring healthcare professional.”
Along the way, Dr. Wasielewski has also served patients by working in the lab. “During residency Dr. Rubash and I looked at the anatomy of the acetabulum and found that we could put screws in safely without hitting the nerves and vessels around the pelvis. You can’t see them so it’s important to establish zones for safe screw placement. Our work is in fact the source of the board exam question, ‘What are the safe zones for screw placement in hip replacement?’ I also learned a lot on the research front from Jorge Galante. I worked in his retrieval lab and published papers on wear in joint replacement. We found that patterns of wear on implant retrievals are not totally explained by design. If a certain design fails, you would expect the wear pattern to look the same each time it failed. It made me think about all the things that affect wear patterns that we didn’t understand. This work led me to research on measuring pressures in surgery. I thought that if we could measure this we could prevent abnormal wear and joint failure. Now I am working with Dr. Rick Komistek of the University of Tennessee on technology to improve the ability of surgeons to optimize implant longevity.”
Continues Dr. Wasielewski, “Recently Rick Komistek and I did a study with Depuy on mobile bearing knees. We inserted sensors and measured the pressure in surgery and saw how it correlated postoperatively with function. Many of these patients have lift off, a sign that the joint is not doing what it’s supposed to. Essentially, there should be no separation of the implant. We found that there are certain surgical variations that influence lift off. We tied things we do in surgery to postoperative kinematic findings. It was very exciting because nobody’s ever been able to measure this before. Now we’re creating wireless implants and instruments so that surgeons can see the compartment pressure throughout TKA to improve balance and kinematics.”
And he never forgot his inventor’s hat. Says Dr. Wasielewski, “From 1992-2002 I served as Chair of Joint Reconstructive Surgery and then as acting Chair of Orthopedics at Ohio State. I was inventing and wanted to retain the patents, so I separated from the university. One of my projects involving intellectual property is on an absorbable acetabulum rim that gives temporary stability to the hip. After a replacement the ball sits in the socket and can dislocate. You can put it into a constrained cup, but then the insert constraint is there forever and creates wear. This is a temporary ring that after three to six months dissolves, leaving the cup to function like a normal cup but provides only temporary stability so patients don’t have a long-term problem. Currently when surgeons have to revise a person's hip replacement they often must be lengthened to prevent the hip from dislocating. To address this issue I patented a liner that gives the hip temporary stability until the tissues have healed. Zimmer purchased this patent from me, known as biologically reabsorbable acetabular constraining components.”
Regarding the relationship between industry and doctors, Dr. Wasielewski says, “I think doctors will always have the opportunity to contribute intellectual property to product development. In the past maybe surgeon intellectual property hasn’t been valued as much as other surgical and design considerations. Most of the industry has spent dollars on consulting arrangements with surgeons, as opposed to spending money on relationships that procure their intellectual property. Going forward industry will likely focus on surgeons with IP. And there will be increased competition amongst the companies for people with intellectual property.”
To help prime the pump for inventions, Dr. Wasielewski gets away from it all. “Yes, I do the golfing thing like most surgeons. But I also love fly fishing, something I’ve been doing since the age of 12. Being out in the wilderness with friends and nothing around is just great. My wonderful wife is a pharmacist, our son is a golfer and 2nd degree black belt, and our 12-year-old daughter is an accomplished English equestrian rider since the age of four. We enjoy traveling around the country to watch her compete.”
